hey Potalot,

I have a cabinet that is 22.5in x 22.5in. x 67.5in. tall. In there I grew one Trainwreck from start to finish with a 400w hps and a 15in. axial fan blowing on the plant. My temps were so high, however, that I could not close the door (plus the fan was too big to fit in the closet).

This time I kept the hps, and added a cooltube, a tube fan, a carbon filter, and a small computer fan, and I am able to keep my temps around 28-30C (81-85ish F) You can check out the the links in my sig, they have pics and more info...

For you, it depends on what you are really going for, and how much you want to spend... I can tell you that one fluorescent light is not enough to finish a grow with. You could use it for the first week, but after that you will need some additional flouro's and even some cfl's. The flouro's have a blue light, so they are good for veg. The cfl's come in 2 different types, one with blue and one with more orange (I think the ones with the lower numbers, 2700K-3500K are blue, and 6500K are the orange,. Get some of the more orange cfls in addition to a couple flouro's and that should get you started. good link:El Cheapo Guide to Lighting (http://boards.cannabis.com/indoor-lighting/121311-el-cheapo-guide-lighting.html). The more light (in lumens and the correct color for veg/flowering) will give you better results.

Take down the tinfoil, as it doesn't do anything. Paint the inside of the closet FLAT white, it reflects much better than tinfoil and better than mylar also.

You want your intake opposite your exhaust, and people normally put their exhaust on the top and their intake on the bottom, but try to get them as opposite as you can (intake-bottom right far corner, exhaust-top left near corner).

The amount of lighting you can eventually get in there depends on your exhaust, and how you can maintain temps. If you have a good exhaust, a 400w hps is possible. Otherwise, stick to the cfl's as they dont't give off that much heat, and people seem to have had a lot of success with them around the boards. Check out some cfl grow logs and get a feel for how much light you think you can fit in that closet.

TWO 400W hps??? Sounds like a lot of light for that space... (I'm guessing its 18" x 18" x 60"?) If so, you will have a little challenge with the temps in that size closet with just one 400w hps.

Maybe you could get a 600w hps in there, if you have a cooltube for it with a strong fan, and a second fan for the main exhaust, an active intake, and/or an air-conditioner...

Just sounds like a lot of light and heat for that small space. My closet is 22.5" x 22.5" x 67.5", and the temps are on the higher end of the acceptable range. Just to be safe, buy a really good tube fan (maybe one with adjustable speeds) and just a 400w.

Go through this:http://boards.cannabis.com/indoor-growing/132514-noobs-guide-growroom-set-up-work-progress.html Try to plan it all out first on paper, and then do the math with the ventilation, it worked pretty well for me.

you might want to get the temps down a bit more. once you get up around 90F photosynthesis comes to a grinding halt. my young plants box gets up to around 85 and they seem to be doing fine, but you don't want to go much over that. 78F is what's considered optimum.

first off, i was trying to help you out. people don't want to decipher your heiroglyphics to try to answer your question. secondly, don't insult other members of the boards. this will only get you banned.

if you can't read or write you have no business growing bud!

I screwed up... blue are higher K numbers and better for veg. Low numbers are better for flowering. My bad...
