  1. hello all, I'm on a £60 budget for a light and I've narrowed the choices down to these 2, 150w HPS or the Ebay LED what would be my best option for 2 plants in a 60cm x 60cm space?
  2. Please move if posted in wrong place Hi everyone. Been reading on here for a while found a lot of helpful information that’s helped me with my first few attempts. Long story short I started growing to help my mum who had terminal cancer with pain relief, fast forward 18 months and I’m now on my 4th grow. I’m struggling to achieve gpw and think this is down to my environment. I have a 1.2m bloomroom loft tent. I have a 6 inch outtake with a rhino filter. Currently using passive intake with a bit of ducting from room below. Running a 600w hps with dimmable omega ballast. X2 oscillating fans, humidifier for veg. 700w oil filled rad for lights off. My fan is a rhino thermostatic but I don’t think the temp control is very reliable. I’ve been using 11l pots with pure canna coco. Using canna range a and b, rhiz, cannazym, boost and pk. Swapped pk for bloombastic on current grow as advised by someone better than me lol. Watering every 2 days up to 2.5L in flower! Don’t seem to be getting the growth I would like in veg and seems to take forever for them to gain size! Now for the questions please! Do I need an intake fan? If so what size? Recommendations on fan controllers for intake outake and heater? Or easiest way to control them all? Would I be better doing 9x6.5l? Less veg time? If so would I put them straight under hps from cutting? A lot more info to share with you guys if you need any to help me! Sorry to ask so many questions on my first post! Thanks in advance
  3. Hi All Im going to upgrade my setup after this crop (my 3rd so far only so i'm still pretty new to it all) currently have a 2.4 x 1.2 x 1.8 tent and i started out with 3 x 600w viparspectra lights. last two yields were only 15oz from 3 plants, and 18oz from the 2nd yield, 3rd one is 2 weeks to go after taking in lots of advice, it seems that those lights just dont output the kind of power needed for decent yields and for this latest crop i have borrowed 2 complete 600w HPS lights with normal parabolic reflectors, and new bulbs (omega dual spectrum, and Lumii Black ballasts). i have retained the middle LED for a side by side comparison.. so far the two plants under HPS are producing much larger and fatter colas so i'm sold on HPS and dumping the LED's. a little about my current setup: 2.4x1.2x 1.8 tent 2 x HPS Lumii ballasts and omega dual spectrum lamps 600w, 1 viparspectra reflector 600w led alien easyfeed system, 30l pots 60/40 coco 24 hour feed schedule rhino 5" 360cm3 fan, carbon filter into rhino silent theromstatic fan controller passive intake using 2 x 8" duct s bends for light baffle feeding canna nutes 1400 oil filled rad for night with inkbird controller plants are 2 x Kritical Bilbao, and 1 Incredible bulk Im growing in my cellar, which helps to regulate the ambient air, its about 15C in winter and 18-19 in summer my next upgrade will be to a 3m x 1.5m x 1.8m tent which will need extraction upgrade im thinking of an RVK L1 6" fan and mountain air or similar filter. i think that gets me up to 60 x air extract per hour even with filter and ducting my real question is how many lights for that size space? i intend to start growing 4 plants. my concern is with heat, and getting rid of it.. and the next question is cool tubes.. do i or don't I some people love them, some hate them. Im having a bit of success at the moment using a dump fan to duct cool air towards the HPS lights, but I hav'nt used this setup in summer yet thanks for takking the time to read and reply

  5. I've been using the Lumii black ballasts electronic ballasts for a while now with 250w and 400w bulbs and they've never let me down. However, I'm a little intrigued by the 'super lumen' setting above the 600w level. From what I can find on the web, this increases the power delivered to the bulb by 10% (660W) which results in a 5-10% increase in output. A 600w bulb should produce 90000 lumens at rated power but could possibly produce a little over 96000 lumens assuming an increase of 7%. This would be suitable for a 1.2m grow space assuming a minimum requirement of 60000 lumens per meter squared for flower. Does anyone have any info/experience on this?
  6. Hi there, new to this forum so your help would be really appreciated! I have a 1.2x1.2x1.9 grow room that I have built, it took me some time and built it to perfection. I have 4 cuttings that I have planted in 3.8l fabric pots, gelato strain. They are on the cuttings and seedlings section on my grow chart, using mainly samurai nutrients. Finally got the temp right, about 21.5 lights off, 25 lights on. Temp has previously got pretty high due to working out the right timer settings on radiator, intake etc. I have noticed that my leaves have started to very slightly turn yellow on the ends, and have started to curl downwards - can anyone advise their experience on overcoming this? I am going to leave them for two days without feed as I believe it may be possibly an overfeed of nutrients or something, then next feed just give water to flush anything out. Does this seem the best course of action? Many thanks in advance!
  7. Hey guys .. I up this thread where all of us can share our grow pics, Only Seedsman strains please Thanks & enjoy!! Testing new gear.. sorry I cant talk about this awesome genetic.. sonn
  8. Hi all, just wondering what your thoughts are on this setup, I’m planning on 4 plants scrogged, each one under a 250w hps in a 1m parabolic reflector, reckon it would be enough light? Some of you may have seen the test plant I’ve got in at the moment, it’s a little purple bud auto and I’m playing about with lighting really just to test it out, can’t make my mind up about the lighting though, I know I could get away with 4x 600w hps but it’s in a loft and I don’t want it to get too hot up there, cheers and happy Toking, RGB
  9. Just wondering if I need a contactor or relay for my single HPS light fixture - I've been using a Lumii Heavy-Duty 24hr analog timer all these years, and it's supposed to be fine without a contactor as long as it's a single light and no more powerful than 600w. Mine's 400w. So, do I need a relay or contactor? And if so, which one's are good in the UK? Just saw the thread about lights killing timer switches and started reading......all the talk of house fires got my frickin' attention! So, wanna know the deal to be safe. Gonna get some fire extinguisher, as that's not something I ever thought about before, but you never know. Lot of wood in my place. And, btw, what's the difference between a contactor and a relay, in layman's terms?
  10. Hiya guys been so long since ive been on here cant even remmber my account, so I had to make a new one. Well Its that time again, going to be doing a new room up. This aint my first rodeo, however Im a bit out of the loop on the modern trends of lighting. Ive been using hps lights for many moons, but years ago I heard many great things about LED and plasma lighting, well years have past and I'm wondering if anyone has any experience with either of them, or if they can tell me if there still more smoke and mirrors than results? Tried looking on youtube but I dont trust most of them, as there selling the lights and could be swapping out the hps for LEDs once the cameras are rolling for all I know. The price of the LED's is the main issue, it varies from not alot of money to holy fuck thats alot of money for a light. I dont mind spending a couple notes on a light to gamble and see what happens, but not a bag of sand. I dont mind spending on a decent LED light if its going to work aswell as a hps does and has lower running temps, but it must be able to yield the same as what HPS does otherwise whats the point? To boil it down to the point, anyone have any experience with a LED light thats onpar with a 600watt hps light yeild wise that dosnt cost near a thousand pounds. Realisticly I wouldnt be able to justify spending more than 5-6 notes on a light unless it can piss over the 600w hps.
  11. Best lights for PG90 tent?
  12. Hi all new to forum , needing some help i am growing gsc autos and having issue i have successfully gemrinated my seeds but when i put them into the 10ltr pots most of them have struggled or died off. I have a 1800 w cob led from china and also a 600 w hps/mh lamp. I have tried using jiffy pellets but the seeds i tried just grew long and whispy and when potted up into the 10ltr and put under the led they died 2 have took. One seems to be starting to sprout its second set of leaves and the other has its first set but one leaf looks damaged. I am basically looking for a helping hand. Am i going under light to early i have my light quite high so to its not to intense for the seedlings. I am growing in all mix bio bizz soil and have purchased bio grow bloom and topmax thanks
  13. Hi all Does anybody know the answer to the question in the title? Reason im asking as I am in week 4 flower, starting week 5 tomorrow and I feel the plants are coming on very slowly, and my Swiss skunk is supposed to be renowned to be a fast finisher, well I can tell you now it isnt. So I can only think 600w is not enough for the size of my room. It is hung vertically inside a 1m parabolic. My room is 2.3m wall to wall wide (7.5ft) by 2m long from wall to door. But the plants dont come that far forward, when they were vegging and small I could keep all plants in a 4ft sq space but as they will out they are literally filling the while 2.3m width now. But I don't think the flower production is that fast at all, do I need to upgrade to 1000w to kick out the most of that space? Parabolic is hung around 1.7m tall The only other thing I can think of is it sleeping temps are high because of being in a loft. Lights come on at night and off during day, now I can see why that would cause stretch and stress but I dont see that in the plants. If you would like to see I have a diary (link in sig) this is not an advertisement but if I might need to upgrade my lights then today is the best day to do so as I am busy rest of week so it all depends what you guys think.

  14. Hi all I am looking to purchase a cheap LED for a tiny veg cab with limited height, around 90cm, its a small room and I currently have a 125w CFL in it. Enrionment is okay but I want higher wattage to cover 9 young plants and be able to raise my light up somewhat. I also know the LED will create some nice bushiness having used a bigger one before, and then I can really pump them in flower under a 600w digi hps in a parabolic. Thing is, being a Yorkshireman I am a tight arse, but I also know I do not need the advanced platinum sun shines out of the crystal backside of my creation series of light, just something with a max draw power of 300w from my socket, something equivalent to 300-450w of MH or HPS light. My imaginary budget is between £40-65. Can it be done? I know the tech is getting better all the time, and prices are coming down as more competitors come on the scene. Does anybody have a joyful story to tell of getting a bargain LED that literally just needs to 'do the job' nothing extra special. Ive considered HPS but even a smaller one will run too hot in there, and because of the space of the loft, flower room and veg cab do not want nor need to take on another ballast if I can avoid. Would ideally like to acheive 30w per plant so 9 x 30w somewhere around 300w of true wattage, but no more from its draw. I have done lots of searching myself, so just wondered if anybody else knows anything.
  15. Hi all, My HPS 600 watt bulb is blinking, but not turning on. I do one small grow with it, per year, as I am a light user. I think I've had it 3 or 4 years, and its only on for 4 or 5 months a year. 24/7 for vegging, 12/12 for flowering. Is it possible the bulb has just reached the end of its lifespan? I am hoping thats all it is, and not the ballast. It was working fine at the end of last years grow. Moved my young plants into the grow room today and it wouldn't start up. It's just stuck on blinking. Anyway, ordered a new Omega dual spectrum 600watt bulb that should be here by Wednesday. Hope that does the trick! Cheers.
  16. High all, here we go then make ya self comfy. A massive thank you to @HSO-Mark for these seeds. Looking forward to watching everyone else's diaries develop too. Gonna be a bit (or alot) of California Sunshine in the UK for the late winter blues I had 5 Lemon Thai Kush and 5 Chemdawg feminised seeds arrive, and they were put pretty much straight into compost... Chemdawg Lemon Thai Kush all the LTK popped up, and 3 of the Chemdawg's did too. Happy with that. I had a spare 1.2m roof qube empty (been waiting years to say that!!), so they're already out of my little veg cab, in the tent under 600w of hps. They look happy, and are growing quickly now they're in the big tent with lots of space, airflow and light. Just given water uptill yesterday. I thought i'd try some root stim. Went with biobizz as i'm using thier grow and bloom. Didn't clock that it's fecking £40 till after i bought it it better be good!! Just tweaked my set-up a bit, and i'm extracting both tents straight outside now, instead of 'vaguely poiting towards a window' and it feels much better all round. Not sure how i'm going to play this grow yet. My self imposed constraint is that i would like to try and get both tents in sync, harvesting one every 5/6 weeks. For that to happen, i would need to flip this tent to 12/12 in about 4 weeks. I have various cuttings from my previous and current grow i can add to or replace with. For now i'm thinking to add 4 plants from my cut's. That should work out about right, aiming for twelve plants in 7.5 ltr pots Also hoping to get the same seeds but in regular versions and get hacking, but for now, i'll focus on these. Nice one, Tigs
  17. Been a while thought i should do a diary.. No pics from veg as i had to move them twice due to inspections etc.. They vegged under 2 x 75w Hs1 led by grownorthern in a .5m x 1m lighthouse tent.

Lit canopy before re shuffle . 150w hans and 250w hps How it is now ... That it for now till next time take it easy ...
  18. Welcome to my new diary ! I shall be trying out a long slow grow with organic ingredients. All my Sweet Seeds ladies are clones from my competition run, I have just popped 5 Ugorg Blues and they are also in the tent but I shall not be concentrating on them in this diary, they will be in the background The soil I have to hand is clover, I'm not sure this is 100% organic but thats what they have all started in for the moment. I am getting a couple of bags of biobizz all mix for the next potting up in a week or two. I am mixing in Guanokalong powdered batpoo, a bit of volcanic rock dust, some additional Mycorrhizal Fungi, a generous serving of ecothrive charge, and finally some additional plagron worm humus. For additional fertilisers I shall be using Canna Rhizotonic (yup it's organic), BioBizz Fish Mix and Biobizz Bloom. I dont think there will be a need for grow, we will see. There are two Jack47's which came from a very healthy branch and big sticks of bud making mother, the mother was small but did really well so I am in the process of lots of LST and topping. They both have about 16-20 main branches on the grow - I intend to have to Jack47 trees, they may get topped once more yet. The plants are enjoying being manipulated, they are thriving as you will see below. The Sweet Cheese and Sweet Skunk clones I have one of each, they are survivors from their wicks not sucking up water whilst I was away on vacation. They will catch up with the jacks, but for now they just have 4 -6 growing tops happening. There are 5 x Urgorg Blues babies I have just moved into the tent also. If I can get the work done on my new shed everything will be transferred to there giving me much more space to grow. Thats the plan ! Heres a couple of pictures for now A closer look at Jack47
  19. Just getting set for grow number 3. I've got the Lumatek 600w dig ballast, the last 2 grows I used a 600w ds lumatek lamp dialed up to 660w for the flowering, about 1500 hours in total. Is there going to be much drop off in efficiency at this amount of use at 660w? There's sunmaster DS and hps 600w lamps at good prices against the lumatek...are they okay lamps, anyone use one with a Lumatek digi ballast? What's people's thoughts about DS or HPS for flowering? For the veg I had a 400w MH sunmaster cool deluxe which would be at about 1000 hours, I've read MH lamps drop off faster than HPS lamps, how much life do you think in the MH? I've got a brand new lumatek 400w DS lamp I could use for veg, what's peoples thoughts on ds or MH for veg? I'm Just going to be growing the one plant scrog this time so looking for plenty of sunshine Cheers
  20. Hi all, calling all sparks helping a mate set up his groom, its in an outhouse on a farm which is approximately 50 metres from the house (we recon to using about 53m cable all in) He will be burying an armoured cable of approx that length to supply the outhouse with electricity. he plans to do a 1k grow so all in probably not more than 1.7 KW should be plenty 2KW should be overkill (he has a 600 hps and a 400w halide and plans to combine them symultaneously for dual spec) he might run a 250 as well for veg The most important thing is that the extraction fan never ever stops turning over and pulling through the CF as there will be workers in the vicinity. the question is, will voltage drop be a problem over that distance? could it make the lights dimmer than normal? and would they fire up OK? (neither of us know much about electricity but I read somewhere that HPS have a "surge" when they first fire up?) he will be coming off a socket on a circuit in the house with only one other socket both of which he will disconnect/cover with a spur so there shouldnt be anything else on the breaker at the main board. the socket hes coming off is about 15 metres from the main board. so does that all sound ok? And what type of cable thickness should he go for for the 50m run to compensate for voltage drop/get best results/be safest for approx 1.5KW (to 2KW max for overkill/unforseen eventualities) thanks in advance for any help, cheers MM E2A: he will also be running 4 or 5 maxijet 500 pumps and about 200watts of fans if that makes any dif re voltage drop. and also he will be using one of those kits that send an internet signal down the cable so he can watch things from the main house on a webcam in case that poses any issues. thanks aggain MM
  21. Hello guys, well there's something wrong with my 20 days Dark devil which seems to be a bit late. i just added a cool tube as you can see in the picture. If you check my profile, you will see the description off all my equipment, style, etc. (sorry to bother you with such as stress). Yesterday I added the cool tube and today I watered with 2 LT ph 5.7 water mixed with 1 ml of rooter x, and 0.4 mg of flower power start (N11 P40 K13). By the way it's a 11 LT fabric pot with canna coco natural soil (really low additives). It was really hot before the cool tube since I switched from the 250w HPS to 400w HPS and moved the light roughly 34 cm from the plants. Temperature was around 31C* as monitored by my parrot flower power tool connected to my phone via app (which can be a bit faulty cause of the HPS light but I'm not sure. I always used it and it worked out really good). The point is my dark devil auto seems a bit weird and dry even if I water usually 2 / 3 LT of water with root x every 2 to 3 days as you can see in the attached pictures. i was wondering if that could be related to the light too stressfull for the plant and/or heat produced as a consequence. Cause I can't think about any other problem.. Any answer or advice is welcome and thanks for the attention. Cheers
  22. Hi all, my babies are currently 28 days old and under 85 watt CFL. I have a 400watt HPS. When shall I switch? https://www.uk420.com/boards/index.php?showtopic=368541&page=2#entry4486962
  23. Hello people, opinions if you will please. I want to set up a separate veg tent and my predicament is should I lay out for a metal halide for the veg tent to go along the line of its a better light for them in veg or do I swap my current all round 400w hps light into the veg tent and upgrade to a 600w hps for my tent which is 1 metre × 1 metre. Many thanks oporto
