Thanks for the replies guys
My grow space isn't that small. It's not like a kitchen cabinet or something. It's in my closet. The space is probably 2'x2' and 5' tall area. If I get a compact flourescent 75watt bulb, do you think that would be enough just to start 1 plant?....
Sure, you can start one plant under a single CF, but be prepared to put about 4-5 x 18-20W CFs in there as the plant veges up, one on top and the rest around the midpoint of the plant height.
You will get
some buds by flowering with the CFs but they will be small, fluffy, low density popcorny sorts. Get a small HPS security light for flowering from the hardware store if you want good bud density.
Sorry, but your 2 x 2 space
is effectively a kitchen cabinet. You'll smoke all you can grow in such a small space faster than you can grow it. If you only had a walk-in closet, perhaps 4'x6' you'd stand a much better chance of getting out of the loop of buying weed.
You'll certainly be able to get one plant flowered in such a space, perhaps two if you use the old Sea-of-Green growers' tricks (remove all branching, flower the plants while still quite short).
Short plants work better with indoor lighting. A 250W HPS security light would give you some nice, tight buds on roughly 25-30" tall plants in an 8 week flowering cycle.
Get your mum plant going, sex it, then do a half-dozen cuttings if you've gotten a female. Flower up the 2 cuttings that do best, just as soon as they set root.
While you're flowering, you'll have to find a place to veg your mum. You might be able to veg in the lower half of the closet and flower in the upper half.
Your ventilation will be difficult; you're going to have to move air equal to the entire volume of the closet every 5 mins (AND will have to trap light from the veg area from getting to the flowering plants).
annnnd.... I suppose you want to keep this thing quiet enough so others in the house are not aware of it?
