hi just want to no if this would b alright

ive just made a little growroom bout 1ft high 1ft deep and 1 ft wide.
and ive got 3 20 watt energy savers to put in still...will just 1 normal light bulb 60 watt do the job or not...and i want to but in atleast 3 plants(lowryder)...not really sure if it will work as it will b first grow?
will any1 recomend a light to use in such a small place
cheers....

hi

a normal light bulb wont do the trick im afaraid

wouldnt of thought so

do u think i should just stick wid the energy savers??

Normal lightbulb ? I think somebody has been winding you up , you can't grow anything with a normal lightbulb .

You can't grow with those either .... well ...you could raise some seedlings... but that's about it...


Do a little more reading .... and a good deal more research .....


Laz

Actually you can , not great by any means but possible .

cheers people...

i just want to start growing soon but want everything to go well ...i will keep reading and just wait till i no want i really want to do


im pretty tight wid space at the moment just need something small like the box i made....

technically you can grow from the light bulb but the results we be well below what you could expect why not switch to a 200w envirolite or even a 125 watt envirolite, ideal for that space although your space could do with a lil more hieght?.. anyways small spaces then its gotta be envirolites... I remember talking to an old geezer in a pub and he told me that years and years ago he used to grow using a few light bulbs in an ol wardrobe.. thing is with ordinary lightbulbs is that they spend most of the leccy they use producing heat, whereas the envirolite is focused into lumens.. think the 2002 gives of 13500 lumens in the blue spectrum and the 125 watt about 9500, for flowering you want a red envirolite, and blue for veg.


good luck man.


cheeeeeech

cheers 4 the info....another thing iv learned on this site!!

stop being mean the lad could grow a joint. an i bet after ten weeks he will fuckin enjoy it.

just another question out of a hundred!!

wat light should i b using under my circumstances.....such a small box and a BEGINER!!!

cheers.....

cheech answered that for you m8.... on the 1st page ....


Don't tho ... waste your time and money using standard bulbs ... or indeed energy savers ...

Yes... you might get a smoke ...of sorts..... but it seems a tad stupid to grow and risk prosecution for such a crappy end result ...

hope it goes well for you ..


Laz

What size pots u planning to use? How much space to you reckon the lights will take up? How much height will be left for the plants?

3 inch wid nd hight pots??

ive made a little box on top of the grow box for the light so i can fit the light in there....hope that helps...

sad but true.
Do some reading. Build a bigger box with more height and get a hps for fecks sake.
Or...
If you want to see if you are capable of growing, get some bagseed and grow it out on a windowsill or under some fluoros or an envirolight.

Incandescent (regular) light bulbs are next to useless for growing weed, believe me..

CFLs are a decent choice but 1 foot of height is a non-starter for a beginner.

oright i thought it would of been ...cheers 4 the advice , im just going to use a cuboard in stead now just going to sack the 1ft box of..put seeds to germ (lowryder...seni star < there mates)
then need to find the right light!!

How many seeds have you started ? - you need to make allowances for 50 percent being the wrong sex ...

Lamps start to get efficient around 250 watts - which would best suit a cupboard maybe 2 foot 6 square - preferably at least 5 foot 6 high - though full height would be ideal.
Making sure the plants can breathe is as important as the lights (also these plants pong - and often we get immune to it)

(I get away with less than ideal conditions because I live alone and can run my cupboard with the doors open. )

6 of lowryder...and 8 of sensi star



the cupboard....bout 7ft high...4 ft wide

Sounds like mine

how deep ?

What you need to do is fill out your profile

You've sown rather more than I would have, but all is not lost.
Personally I wouldn't have bothered with the Lowryder unless I was growing outside.
The 8 Sensi Star should be a nice easy beginner's strain.
I suppose we'll have to see how many actually survive

If you look at my grow, it may turn out to be very similar to your cupboard. The first two grows it worked out well to sow 10 and end up with 5 females - though I'm quite likely to be getting only 4 this time ...

If your cupboard is a bit deeper, it may well accomodate more plants - my old one was 3 foot 6 by 2 foot six and I used to sow 24 seeds and flower 12 .

Let us know about depth, ventilation etc ...

as FF said 1ft height with pots about 3" high gives you 9" of growing space to the roof of your box, however my Lowryders were around 23" tall i think you need to get back to the drawing board mate!!
T1

EDIT: Disregard what i said, now you have a decent sized area to grow in everything should be fine. what light are you thinking of?? i reckon a 250w hps or 2 in there provided you have the extraction would be great.

i was going to use 150 watt hps...but might re think bout that...o yea the cupboard is just under 2 ft deep ...and just going to use pc fan

I'm really coveting your cupboard.

I would go for a 250 watt - you can easily add a second one later and grow a wild mix of genetics like I do.

250 watts is the point where HPS efficiency really takes off.

4 foot is a big stretch for any single lamp and you, like me, don't have sufficient depth to be able to use a single 600 watt lamp and parabolic reflector like uncle Owderb does (feels curiously appropriate that, despite our age difference )

Where is the cupboard located in relation to the loft/attic or an outside wall ?

(and how near the front door ? - though my pongs always used to find their way downstairs ...)

You could grow with a light bulb, but i'd imagine heat would become a problem in such a small space. You'd probably need constant air exchange. Just remember that incandescent bulbs are deficient in blue light so you'd have to put some fluros or somethin in there anyway. You'd be dissapointed if you did an incandescent by itself.

Muad'dib, please read the rest of the thread. Incandescents are not suitable for growing.

And the date

Yeah I replied a bit prematurely but once you hit the button theres no going back... besides i'm kinda new around here so I've been readin through some old threads...
Besides I've been told by enough of you what is and what isn't suitable for growing, I'm well aware of the spectral output of an incandescent bulb. The truth is, you can use incandescents, just not by themselves, and you have to compensate for the heat so you can bring them closer, and don't give me some shit about lumens either.

Look .... don't waste your time with incandescents ...

supplemented or otherwise...

Muad m8 - do some reading and a little further research before posting ....


..." don't give me some shit about lumens either" ...


Laz

First of all, they sell incandescent grow bulbs at the hardware store, I wan't wasting my time with anything, I was just making a point. The highest rate of photosynthesis happens right around 660nm, which incandescents produce a whole lot of. Maybe you need to do some research.

Ok m8 .... you know best, carry on ....


...Don't forget to post some shot of your harvest ...


Laz

Yeah - at around 2% efficiency.



e2a: And it's 450nm and 680m, which are the chlorophyll absorption peaks.


Type Overall luminous efficiency
40 W tungsten incandescent 1.9%
60 W tungsten incandescent 2.1%
100 W tungsten incandescent 2.6%

Muad'dib, a lot of research has been done into what lights are suitable for growing. Practically everything that produces light has been tried. And the research is ongoing, we even have people growing under LEDs. The consensus of that research is that incandescents are pretty much the worst thing you could choose.

If you think that we've all got it wrong, fine. Do a grow your way, post a diary, and prove it. We will all apologise and congratulate you. But until that time, if you continue to post what we believe to be bad advice, people will correct you. You seem to be aware of this, in which case I submit that your post in this thread is little more than a troll. In other words, put up or shut up.

I don't really understand why anybody would choose to grow with incandescent lightbulbs ?

If it's some kind of experiment thats fine but the guy actually wants some end product from his grow I believe .

I have grown using CFL's so it is possible but if you are going to take the time and effort (and risk) to grow then you
might as well get some decent lights .

Good point! And thank you all for posting some intelligent conversation, instead of just chastizing me. My remark was only to say that it was possible, not to say that it was anywhere near as good as other lighting systems. The fact is you'd probably have to jump through hoops to get any kind of comparable result.


Incorrect. The absorption maxima of chlorophyll a are lambda= 430 and lambda= 662 nm, that of chlorophyll b are at 453 and 642 nm.

Also, not sure what the source was at the moment, but I did read that the greatest rate of photosynthesis happens at around 660nm because the ratio of chlorophyll A to chlorophyll B is about 3:1



HAHA! Touche. I intend to though, I have the experiment set up conceptually in my head, but the reality of the situation is that between my 12 hour work days and my other responsibilities I don't get a lot of time to work this stuff out, but you can expect something by the end of the summer. I will probably use halogens though and not standard incandescents.


agreed, but that doesn't mean its not possible.


OK, but you have to remember that those ratings are based on LUMENS. Lumens do not measure how much light a source produces, they measure brightness (to the human eye more specifically). The brightest lights (HPS etc) produce a whole lot of yellows and greens which come up very bright in human vision but are not particularly photosynthetically active. The wavelengths of light that plants use the most are not very bright at all.

In a way you've touched on the very thing that drives people to experiment with things like LEDs .. even HID lamps produce mostly heat.

I suppose if you're used to paying £150 an ounce for schwag, you might be content with 500 watts of quartz halogen floodlight in a DIY cooltube .... who knows, the £100 worth of electricity might produce an ounce ... but then Blab's microgrow made 3/4 of an ounce with 80 watts of CFLs ..

It's difficult for those of us who started out pre-WWW, to keep quiet when we see the new generation of growers in danger of making the same mistakes we did . (My own 160 watt vertical fluorescent experiment ended as soon as Sunlight Systems brought out a 250 watt HPS.)

I've no idea why they sell incandescent "grow lights" .. I suppose it's because there are people who are happy to buy them ...

I think you're taking all this a little too seriously bud. I was just making conversation. I have no problem with people correcting me, I am in fact, human, and make mistakes all the time. It's when people call me an idiot that I get defensive.

M ..... no one is suggesting that it's not possible ... (sighs deeply.... )


Just that its a complete waste of time, effort & money and a needless security risk .... for no sensible harvest at the end of it..

you carry on... 'experiment' away m8 .... good luck to you...


But any experiment with Halogens doesn't really have much to do with the case in point does it?....


Laz

Yeah you're right I guess, the truth is when i originally posted i was thoroughly baked and only saw the first page, and it seemed incandescent was all he had to work with, so I was remarking that it was probably do-able. Things sorta got out of control when people started saying I didn't know anything, and if you knew me, you'd know I never back down when theres some good intellectual banter.

On a side note, I was under the impression that halogen and incandescents were essentially the same thing, the halogen was just an attempt to improve on the weaknesses of incandescents.

Isn't this an experiment forum...

No-one minds discussions about what might or might not work, in fact as you pointed out in many ways it's what this forum is about. But you posted in a thread started by a newby who wanted advice on how to light his grow. This is inappropriate, he might easily have gained the impression that lighting with incandescents was an accepted solution. Or someone else reading the thread might. That's why we jumped on you. Newbies often get confused when they get lots of conflicting advice, because they don't have the experience to judge what's best. A newby published a thread about this just the other day, pleading for definitive advice because he had had so many contradictory answers to his questions that he didn't know who to believe.

If you want to have a theoretical discussion about the use of incandescents and halogens, start your own thread and make clear at the beginning that it's a theoretical discussion. Then there is no danger of misleading anyone. You'll probably still get lots of people telling you it won't work, mind, but they won't tell you off for posting it.

Indeed, I certainly won't make that mistake again... you guys are pretty friggin intense

Is that enough for an apology? If you read the rest of that guys site, i'm sure you will come to the conclusion that he is legit.


HA sorry I forgot to link it. here it is...http://h1.ripway.com/opticspdf2/

If you fancy setting that up, I have a shed load of 4 foot fluorescent fittings ....

mate, put those lights in that box, grow some half decent weed in it and then you will convince someone of something.

i've used strip flouros and there is no way that amount of light in that box will yeild more than a couple of bongs worth, i have 1/2 that light in a shoebox just to do two mums and a handful of cuts

So pack it into a smaller box. The setup costs about what 2 grams of kind bud costs here, so as long as you got more than that it would be worth it.

go for it

The electricity, on the other hand ... a tad under £50 ... though still only the price of a third of an ounce of schwag ....

... on the other hand, a 250 watt HPS (300 watts inc. losses) in a more sensibly sized box - say 2 foot square is good for 4 ounces at least.
