Hi all, I'm a bit of a newbie at this but i've been reading up for quite a while before starting out.
I've built a 'stealth-shed' but i'm not sure if it's going to work so thought i'd ask you guys what you think. The idea has kind of evolved but I fancied growing outdoors but it's too risky to have things on show AND I needed a shed for so I thought i'd combine the 2

Me and my partner both have kids so I had to come up with a way of having the plants in the sun all day but not attract unwanted attention, it's in a good spot and gets direct sunlight (when it's out) from about 10 am till 10 pm and so far only has a solar powered extractor in the roof that extracts air whenever the sun comes out. In the next week or 2 I intend installing a 4" carbon filter (extracted at the front at roof height) and a filtered air inlet at floor level at the back.
Might be better just to let the pics do the talking but the idea is to keep the plants just below roof height and lower down the shelf as the plants grow, all the surfaces are matt white for maximum light reflection inside the grow area and I've had to put bubble wrap under the plastic roof sheeting to prevent anyone seeing in from the outside. If the natural sunlight isn't enough I've been thinking about the possibility of having additional cfl lighting inside to extend to a 16/8 or 20/4 schedule and some way of blacking out the light getting out at night.

Not sure if the bubble wrap will block out too much of the sunlight, has anyone had much success growing in similar situations?? I'm interested in all comments, good and bad. If anyone needs more info please just ask, would love to make this somewhere my girls can thrive in peace

Here's some more pics

And the rest

i grow in me shed mate but yours is really "unique" idea. just be careful so neighbours dont realise how "unique" it is

You wouldn't believe just how careful i'm being , neighbours shouldn't be a problem, got high fencing up all around the garden, just hope no-one asks why it's a different shape on the outside to the inside, it's like doctor who's tardis only smaller than it looks on the inside!

Oh, and it can't help with the time travel stuff either, imagine planting seeds then travelling forwards to harvest time!

It's the amount of light and bubble wrap i'm not sure about, along with night time temps and air flow etc, hopefully all will be well but the plants you can see in the pics were seeds 3 weeks ago and they don't seem to be growing anywhere near as quickly as most of the pics i've seen on here but they did start off in crap compost and have had no light up to now apart from sunlight on the window sill and tap water, the smaller of the 3 pots is a seed just breaking thru the surface so I,ve just ordered a 125w veg envirolite to start it off under to see if that makes any difference. First try at growing my own so am very glad to have some experienced growers on here to ask and lots of threads to read up on.

Not read much about outdoor growing but for the price of a CFL, if you can afford it, you may aswell black the roof and use that. With the weather we have in england (depending on where you live) it wouldn't suprise me if you could get more light off the CFL than what you could via the sun roof.

Like the idea of the stealthyness of it tho, gl with it

Looks really ingenious, I hope it works well for you. Not sure about the bubble wrap, if you can do without it I would get rid to get as much light as possible in there.

Good luck

I would add a little lighting as mentioned before. Perhaps a few daylight tubes on the walls.

Nice Buddy Looks Shit Hot Hope All goes well for Your grow mate

gavmc

Looks very interesting indeed! Please keep us up to date how it works our for you!
Will stick to this for sure!

I'd say keep the sunlight, its the best light in the world!! Even on dull days the UV sunlight gets to the plants . It might be a good idea to suplement the light with a bit of leccy though as the light is only coming from above so not much direct sunlight apart from at midday. If your growing in it now dont need to worry about heat too much as theres lots of people growing outdoors over the summer.

Cheers for the info guys, it's always good to listen to different peoples opinions, have got a 125w envirolite on the way to give them a boost and i'm a bit late starting them, will have to suck it and see I guess but thanks for all your input so far, I've heard we're in for a really good summer this year so i'd like to keep the sun option open, I may try some kind of hinged cover on the inside with some lights hanging on chains underneath that fold back to the wall as the cover hinges down, could switch between the two in seconds but would the plants get pissed off with me interfering???

Thanks again, keep the ideas coming, it's all good.

I think the natural light along with the enviro would be a great combination. I reckon you will get a great crop just make sure you keep a fan going at all times as I reckon it could get a little stuffy in there around mid day.

looks great, i've thought about something similar in the past, but never quite got it together

Cheers again guys, am grateful for the advice. I got my light unit today, Jesus it's bigger than I'd imagined, it's only a 125w but 'Maxibright Compact Fluorescent Lamp' my arse! How the bollocks they can print 'Compact' on a box that bloody big is beyond me!

I also got a temp/humidity guage that records hi-lo for temp and humidity so at least i'll know whats going on in there now

Also ordered a roll of the diamond mylar stuff as it's clamed 95% light reflective and may help with a bit of light penetration if they ever decide to grow leaves and i think i'll build a veg cupboard in the corner for the future to give them some decent 24 hour light to give them a better start in life than these have had, grow lamp at night sun in the day if thats possible, also got some grow and bloom and big bud but will have to learn if/when to use it yet. Is there anything else that's a must-have to keep on hand to treat them for any insect/mould/rot/rabies they may get?

It's all good innit, looking forward to this, plant ownership of any type has not been good if i'm honest so hoping to do better.

Hey stealthshed looking nice. I had a mate who did something very similar, although he opened his door during the day as it was facing a paddock, but same clear roof design. He grew 4 plants in pb70's and pulled almost a pound a plant last summer. So it definitely works, imo.
B

Excellent, sounds very encouraging apart from I haven't got a clue what a PB70 is, excuse the ignorance...... i've googled it but decided your mate wouldn't have grown 4 plants in a 110v electromagnetic drill or a 150w power amplifier.

I'm a bit concerned about the size of my plants, been reading non-stop on the forums whenever i can to get myself up to speed and every thread i've seen with 4 week old plants are lots more advanced then mine, I've also read that the first 2 or 3 weeks set a plant up for the future so my question is should I stick them under my grow light 24/7 to give them a boost or am i weeing in the wind and should I bin them and start again. I know an outdoor(ish) grow is going to take longer than a fully kitted out indoor grow but mine are only about 5" tall with the 3rd set of leaves just growing (if you count the original round leafs too), the feminised skunk#1 is slightly shorter but the unknown one is a bit lanky but they've only had natural sunlight up to now. Is it too late for them or should I give them some love and light and see how they go. The pots are slightly big for their size as i had to re-pot them as 2" seedlings as the compost they were in was utter crap but I can see one of the main roots at the bottom of the pot already so maybe they're filling the pots with roots instead of going skywards for now and they'll get their arses into gear if I give them 24 hours of cfl for a while?

Thanks in advance for any thoughts as always, will take some pics tonight and post them so you have a better idea of where they're up to, they look healthy enough, just small.

Don't bin them plants just yet Stealthy - some of my plants are only about 6" tall - getting just sunlight - and this does give them a slower start than if they were under artificial lights. Fillin up roots in the pots is good - and you dont want your plants to be too lanky as they start to bush up.

Many on here are using both natural and artificial lighting with absolutely amazing results.

SL

Cheers for the info bud. Will keep going with them for now.

The shed isn't working out very well so far, it needs the ventilation sorting out before I can use it in the day when it's sunny again, the thermometer registered a low of 12 degrees C the night before last and a high of 62 degrees C in the day!! Ouch... even with air coming in under the corrugated roof and a PC and solar fan running on the vent in the roof it's nowhere near enough. I'm surprised they survived at all, was a very hot day here yesterday, hottest of the year so far.

Here's a couple of pics of the skunk#1 just after they came out of the shed... it's 4 weeks old

And this is the 'unknown' plant

You can see on this one that there's slight damage to the tip of a leaf, i presume this is due to the heat during the day

Given that the shed is not suitable till I've got the air flow sorted I quickly rigged up my new lamp temporarily to see if that would help but it appears to have made matters worse! .... on the taller unknown plant one of the leaves is looking fairly dead, the first pics are the temporary light setup and the bottom ones are of the plants in the morning just out from under the lamp, the smaller skunk#1 seems ok tho. Do you think the leaf damage could be a result of the heat in the daytime or could it be from the gro lamp?

My last seedling failed to surface so i've got 2 more on the go, one straight into compost and the other in tissue paper just so i've got a couple more started off in case these don't make it.

some roof sheeting is designed to keep out some of the suns rays , you might be better using glass?
i have a few outdoors and have seen 3 inch growth in the last few days and believe me no plants have had a start as bad as these ! long story but a while back they spent half a day down the toilet

Hey up m8y 1st welcome to the best site around

2ndly dig yourself a fucking big hole under the floor of ya shed drop in a box an hey ho you got a super stealthy room

Best of luck what ever you decide to go with mucka leepy

LST

i think something like this would be perfect for your shed.
rather then the bottom buds not really getting any sunlight.

yer right.... like anyone's gonna be mad enough to try that Leepy Thanks for the welcome and good wishes.

Cool thread tho, hats off to you matey for sticking with it, even if it WAS just so your garage didn't cave in hehe... can only try to imagine the highs and lows of doing that, you deserve every oz you harvest.

Thanks for all your input again ..... Down the toilet! I won't ask any more Sky but it gives me a glimmer of hope that I might be able to rear one of my own .

There's a website for the roof sheeting I got so will have a look later to see if there's any info on it regarding sunlight.

I've had the plants in the garden in the sun all weekend and under the 125 enviro at night and the smaller one seems to have bulked out a bit plus i took them out of their pots yesterday and there was only a few single roots winding their way thru the 'Homebase Gro Bag' soil so i took away as much soil as possible without damaging them and put them back in some west plus and there's more roots in the new stuff tonight than there was in the homebase stuff they've sat in for 10 days or so. The homebase got a good score in the trials but that's when it's used for large shrubs and bushes, it doesn't fare too well well in the seeds and cuttings category.

A new seed from the unknown batch has just popped in a small pot and i've put another in some damp paper towel to see how that goes but the seed was a bit lighter than the rest, a green colour instead of brown so I don't know if that's going to germinate but nothing yet, also got a 5" ruck fan on order with filter etc so i'll see how the temps/noise levels go in the shed with that running, hopefully get sorted for next weekend before the plants put on a growth spurt and get too big to be moving in and out during the day/night.

As mentioned above, the smaller skunk#1 has bulked out a bit and looks quite healthy now, the taller unknown one has had it's bottom leaves die off but the new growth (which has speeded up with the long sunny days and enviro at night) looks fine so will have to wait and see, will post some new pics soon. Cheers again for all your help.

Cheers buddy but the link doesn't work for me??

LST is super easy simply screw hooks into the side of the shed and use twine to pull the plant stalks down and outwards makes a wide compact plant a bit like scrog.

It's going to be a hot summer this year I would hook up some decent ventilation and I would also use a cover for your shed (So you can start 12/12 in mid July while the sun is brightest) it'll be too hot to use the light in there soon.

Because the only light source in there is the roof as long as you cover it so you reduce light times for the plant s to 12/12 you can flower earlier then normal using just the sun, this is a big big advantage and something I considered myself for a homemade polytunnel project I'm going to do one day. (Not for MJ growing)

If you really want to use this shed I'd consider adding celotex as the temps combined with good ventilation will be far more manageable in summer and put a lid on the shed and you can grow in winter as well (Just remember celotex the roof of the shed in winter.

If I was to grow in winter there I'd use a digital 600w ballast as the heat produced isn't too far off what my 250w enviro produces and once you use HID lighting you don't go back.

Sorry they are probably called something else in the UK. Short for Planter Bags. Thin black plastic bags that come in varying sizes, pb70 is a 70L bag. Great for Guerrilla grows as easy to carry heaps of them to location, but work fine in a shed too! I'm sure there is something similar in the UK. I got onto them after working for a large tomato greenhouse who used them filled with sawdust. Fuck I hated that job though. Who would have ever known cucumber plants are covered in a million cactus-like needles! Had rashes everywhere

Anyway, sorry to ramble, but a big deep pot would work just as fine, try go for 70L plus though if your wanting some big plants!!
B.

Thanks again for your replys guys, excellent stuff. I know what you mean about the planter bags buddage, will bear that in mind as i'm thinking of using one of the plants in a gurilla-grow and would be excellent for transporting one in, nice one. Am planning on making an internal shutter of some kind and yeah have been thinking about celotex or similar, would help with day and night time temps AND noise reduction as well as. I bought a couple of 120mm 12 volt fans at the weekend and fitted them into the floor to drag cool air in from under the shed, they're connected to a battery in the garage with a decent sized solar panel topping it up and a battery charger coming on for an hour or 2 as well in case it's cloudy. Have also got a decent oscillating fan in there pulling the fresh air upwards and over where the plants will be so all I need now is the 5 inch Ruck fan and filter to arrive and i'll sort that asap and leave it all running for a day to see what the temps get up to in the middle of the day, is cooling down from tomorrow with rain forecast for the weekend so will have to wait to test it when we have some hot weather again, typical!

Have thought about a scrog in there too, have just got some diamond maylar and it looks ultra good and should bounce the light about a lot better than my white paint but a nice even flat canopy might be just the thing. I like to think outside the box wherever possible and have also toyed with the idea of making a very slow turntable like a record deck that will rotate the plant(s) and have a light or 2 at the side(s) (think a slow doner kebab grill but replace the kebab meat with a nice plant and the grill with a lamp!), has anyone ever tried this?? do cannabis plants get dizzy?? It would ensure no leaves were stuck in a low light level area and would promote good even growth and ventilation, would also produce a shorter stockier plant maybe??


Anyway here's some pics, it's amazing how much they've grown over the weekend with sunny days and enviro at night. The smaller skunk#1 looks almost healthy now. The taller unknown plant has almost totally lost it's bottom 2 proper leaves (can't see them in this pic) and it has damage to the tips of the next leaves up but the new growth from over the weekend looks very healthy. Do you think i'm right in thinking this damage was down to the extreme temps they were in for a day (went up to 67 degrees C!!) coupled with low humidity drying the leaves out or does the damage look like something else (they were in crap compost for a while THEN the homebase grow bag soil and now finally the west plus), will stick a pic in the sick plants section if need be but thought i'd try in here first so peeps can read up on how the plants have been grown so far etc.

Anyway enough waffle from me, here's the pics and meet the newest addition, this is another of the unknown plants just in case the tall scabby one doesn't make it or is a male.

Really interesting setup you're developing, I think it will work well if you can manage to control the environment OK. It's definitely good to make the most of the sun's rays and cut down on power usage. I think the scrog is a good idea too as I imagine the sunlight low down in your shed is not that bright, I think if you can keep the canopy close to the window at the top of the shed the results will be good.


I would think it is almost certainly the temps and humidity that are the cause of the plants problems. The middle pic does look like it might have some nute burn. Not too sure but they might have gone into the grow bag compost a bit too early, it is probably a very rich compost. If the new growth is OK I wouldn't worry though I imagine it will be fine.

All the best with the grow, looking forward to hearing more

Cheers mate, will keep you up to date. Part of me wants to sack it off and take it all indoors, I have a walk in loft off my bedroom that's ideal for setting up in, always stays around 25 C in all weather and it's where I set up the temp cfl. The attraction of the free sunlight is too great for me to ignore tho and i'd really like to make it work although as you say temps could be a problem, will know more as soon as i get the main fan, if I can I will.

The fan and carbon filter arrived today along with the essence kit, flowering enviro bulb and fitting, will be fitting this (the fan, not the essence!) in the shed tonight and see how the temps go, yesterday it maxed out at 45 degrees C so getting there but it's a lot cooler outside anyway, have wired the 5" ruck fan up and I'm surprised at how much air it shifts but it's quite noisy for an outside project so I'll probably wire in a speed controller in to slow it down a bit, got the 5" instead of the 4" with this in mind temperature permitting!

Can't believe what a difference the enviro has made to the rate of growth of the new seedling, I didn't have one when I started off the others so hopefully this one will have a much better start in life, deffo a must-have in my opinion.

Can I use this thread as my grow-diary or should I start a new one??

I think if you can it would be worth sticking with it with the shed, you will save yourself a packet on leccy if you use sunlight as much as possible. Not quite sure how you would do it but is there anyway you could increase the thermal mass of the building (pile up stones or soil against the sides or put a large volume of water in the bottom) as this would help stabilise temps a bit if the fan is insufficient.

The enviros definitely make a big difference compared to sunlight alone, especially outside of summer time in my experience. Once they're beyond tiny seedlings make sure you keep the bulb very close to the plants.

If I were you I would use this thread, it will save you reposting your pics and info, unless you fancy tidying it all up in a new topic. Mine wasn't intended to be a diary but it soon seemed to grow into one.

Hope they'll all still coming on well, have you decided whether you're going to attempt a SCROG yet?

Hiya Net, thanks for the reply. Can't do a lot about the building apart from celotex all round which I intend doing asap as I cant cover the room in mylar till I do, will try and get some for next week then I can get it finished off as much as possible.

I have high hopes on the temperature front, I had previously fitted 2 12v 125mm fans to the floor with very fine netting underneath to act as a filter, it's actually a sun screen out of a car but the mesh is so fine it's ideal for keeping things from entering the area. They work ok but nothing to get too excited about... till I fitted the main fan last night. As soon as I switch the main fan on the 12v fans go much quiter as they're only helping air in now, I can feel the draught from the small fans from 2 - 3 feet away now where before you could only just feel the air coming in from 3 - 4 inches away. The noise isn't too bad either and once I've tested it during a hot day i'll be doing a more permanant job of fitting it and boxing in around the fan and ducting to further reduce noise levels, then there's the celotex too wich can only help with noise reduction too. With the fans running now I can feel lots of cool air coming in from the floor and moving across the room before going out thru the carbon filter and that's without the fan I'm going to be using to aim thru the canopy so it's all good I think.

The more I think about a scrog the more sense it makes, the only downside I can think of is that it would render the plant immobile for if I ever needed to move it for any reason but I think the results would deffo be worth it so yes, I think i'll be doing one plant at least.

Anyway, here's the pics so far for my new gro diary

Glad to hear the fan is working out well so far, hopefully it sort the environment in there out nicely and give you excellent stealth with the carbon filter, I'm starting to get jealous



Could you have the plants on a shelf that you raise and lower (or did you already say you are doing this) as it would let you keep the canopy very close to the top and also you could lower a plant out of the screen if you really needed to move it (would be a bitch to get back in though)




Glad to hear it, will definitely try and keep up with how you get on.

If the fans don`t manage to reduce the day/night temperature swing you could bury a load of perforated pipe under the shed floor a couple of feet deep and route the shed air through it.
Soil temps are a lot cooler than the outside air in summer and warmer in the winter.

That's not a bad idea Geo, will bear that in mind. Cheers buddy.

LST link that didnt work before^^

Looks great fella, good luck with your grow

Thanks for that, have read every page a week or 2 ago, is deffo food for thought and an inspiration to most




Cheers for the good luck wishes, am needing them at the minute .

dont go for a controller unless its one of the silent 100 quid + jobs , i bought a one (50 quid) to quieten a 10" rvk and the buzzing from the controller was louder than the fan was without it

I think this is gonna work for u mate. Not only will you provide your plants will artificial light, they will also receive natural light. All this has to = great bud.

Good luck

Cheers for that, good advice I recon too, cheapo's and dimmer switched make a hell of a racket and outside on a quiet evening i'll bet they'd be really obvious



Thanks for the wishes again, I think i'm gonna need it, things aren't going too well at the minute, have posted loads in the sick plants forum but only got one reply but no advice on what to do to solve it.

I potted them up last saturday, I did this a bit earlier than I think you're supposed to but I want them to go into big outside planter tubs to go into the shed as I won't be able to repot them once it's attached to the scrog mesh so they've got lots of new food then I watered them in with 5ml epsom salts and 3ml grow last friday evening (grow was a mistake I think, even 1/2 a dose) then treated them with essence on sunday, all I can think is that it was all a bit too much for them? I'm guessing really but have been reading up a LOT this week, Bish linked to a post where the plant had heat stress and it looked the same but I don't get how as mine were out in the sunshine all weekend (cracking weather) and under the 125w enviro (veg) but a couple of inches away with a 10" oscillating fan aimed just on and above the plant tops about 3 feet away grow so nice and cool (25C, RH 40 - 50). I've since built a veg box and added another 125w enviro (flower) as well now, but they have continued to curl / dry the leaves up and and have gone paler green around the edges and between the veins of the leaf and the leaf surface isn't flat, it's all raised and rough. I thought i'd over watered them so haven't watered them all week till tonight as the pots still felt quite heavy, they've not put out a lot of new folage but the new leaves that have appeared are slightly pale around the edges. I've flushed them with plenty of plain water tonight and let them drain for a while, don't know what else to do but just leave them to it, could do with a little guidance really, will post the pics here as well.

On a brighter note I've got the insulation boards today and made a start with that, have fitted the fan properly and insulated around it and the ducting and all you can hear now is the air getting sucked into the filter, gonna run the fan during the middle of the day and monitor max temps and do the same at night with only a small single fan on the floor to keep temps up as high as poss once the insulation is finished tomorrow hopefully, have also got some plastic coated mesh to do the scrog with, if the temps are good enough I want to stick one or 2 in there permanant as they're getting too big to be moving about, I might grow the larger of the 2 unknowns inside then I can go 12/12 earlier (if it lives!) with that and harvest sooner, the smaller of the 3 is doing ok, is only a couple of weeks old and has had a much better start than the 1st 2 did in better seedling compost, have potted it up into some AJB with syncro.... I read a thread where a couple of guys were raving about it being the closest thing they'd used to the now ledgendary west from a couple of years ago, it's loving it so far and I'm not gonna pot up till it's good and ready this time, lessons that have to be learnt I suppose.

Here's the pics from today, the rest are here in the sick plant section

Oooops sorry forgot link, the rest of the pics are here http://www.uk420.com/boards/index.php?showtopic=178729

It is indeed hard to understand how it could be heat stress. Does your thermometer record the max temperature or have you just been checking on it every now and then? Also I'd ease off the Bio Grow, if they've just been potted up they won't need any food until they've used up the nutrients in the compost. Hope they're coming along better now

Cheers for the reply buddy. Only gave the plants a small dose of grow once, nothing since, was just trying different things and i know some people do feed earlier but as a rule nothing till a week or 3 into flowering, have only given water since, have currently left one of them unwatered last night to check i'm letting them dry out enough. The plants seemed to get worse again after being outside during sat and sun daytime, twas a lovely sunny weekend with a lovely cool breeze and just right for growing weed I would have thought but apparently not. Have updated my post in the sick plants section with more pics, looking back at pics taken just 6 days ago in that thread they've grown quite a bit but the problem still persists, the problem is that anything you try takes days to show the effect and they're running out of time, here's a link to the thread in question to save putting it all in here again. http://www.uk420.com/boards/index.php?showtopic=178729

My grow is turning into an inside grow a little, not what I had in mind but i'm scared to put them out again as it appears to be making matters worse if anything. Thanks for your reply tho mate, am very grateful for the interest.

Hi, yeah my temp/hygrometer records highs and lows so i can see whats been going on with the temps/humidity. Turns out it was mostly heat stress i think although there was some nute burn also due to me trying a few different composts before i was happy. The plants haven't been outside due to the damage and i've been looking after them inside till they came good again, which they have. Here's a pic of them now, they're lots better. Plant 1 is first, it's a sensi femmed skunk#1, it's put on a LOT of leaves since the damage.

Plant 2 is from some seeds a mate gave me, this was damaged the most but it's put on quite a bit of growth since, was thinking of putting this one in the shed soon so long as it works out on the temp front.
Click to view attachment

And here's a group shot with plant 3 at the front, this is another one of the unknown plants that's around 23 days old and doing really well
Click to view attachment

Have lined the grow section of the shed with celotex and it's only dropping to about 15 degrees C at night now but i'd imagine that will get better the further into summer we go. It's a LOT brighter in there now (right down to the floor level is very bright) with all that foil backed celotex, does anyone know how good it is at reflecting UV light, can i leave this as is or should i still cover this with mylar?? The downside of the celotex in there is that the daytime temps have increased. (possibly an indication that the celotex foil is converting the light to heat like cooking foil does so therefor it's not suitable as a reflective surface for growing??)

On breezy days the noise from the fan is unnoticable as it's masked by the wind etc but on days where there's no wind at all you can hear it faintly and i'm not 100% happy with it so i've got another 5" ruck on the way but one of the new ones with the built in thermostat that slows the fan down once the req'd temperature is reached, hopefully then the noise will be limited to the hottest parts of the day and in the evening/night it should slow to a crawl just to keep fresh air in the place, i've also got another PC fan hooked up to a 40w solar panel that comes on when the sun comes out on the intake side, have got a normal plant in there as a test victim at the minute and it's bloody hot today so we shall see how it goes. The ruck that's currently in there will do for my indoor area, got another CF on the way for that too. This way I can grow indoors and out and at least I should be able to swap between the 2 if the shed gets too hot and they need a little tlc.

Is there a maximum recommended veg time before flowering, might force one plant onto 12/12 to get a harvest sooner indoors, they've both grown girly bits in the last couple of days.

Am gutted to say this but have had to scrap the shed idea, the recent heatwave has knackered up any chance I had of keeping the temps down to an acceptable level, I'm thinking of taking out the top 1/2 of the internal wall inside and creating a platform 1/2 way up under the poly roof area and using it to grow veg and strawberries and to start seeds off for flowers in the garden etc. During a normal uk summer it would probably have been ok at a push but with temps hitting just under 30 degrees outside then add in the sunlight into a reflective surfaced room and voila...... instant oven!! Even with the new 5" ruck doing it's best (best = more noise) along with an oscillating fan blowing cooler air upwards from the six 4" holes along the back floor edge with 2 of these holes also having 120mm pc fans going hell for leather dragging cool air in from under the floor it's still hitting silly temps this week. Did some tests last week and had managed to keep the temps down to the high 20's but just hitting 32 during the hottest part of the day which is bad enough but now it's in the 40's so probably not a good idea. It could be done, but not without making noticable noise and attracting attention to it, just not worth the hassle even after the time and money spent making it and kitting it out.

Did i mention about being gutted! shit happens i suppose. Cheers everyone for the input, some you win some you lose.

what a shame bro,
can you niot find somewhere outdoors for em .

if only as a trial??
be a shame to see them go to waste.


peace and i feel for you

Really sorry to hear the temps have scuttled the grow shed, can you put the plants somewhere else?

I'm not too sure but if you really want to try and make it work you could try covering the top with some shade netting to keep the temps down., I imagine the plants would still get plenty of usable light.
