So, I've been contemplating whether or not to grow my own for awhile. I just want to grow one for now. I'm working with a pretty small space here, like 2x2ish? Maybe more. I don't know how great of a space that is for growing a plant, so would it even work? It's the only space I have available.
How much lighting do ya think I would need? Is an HPS really needed for one plant? I don't want fluffy buds though from using a florescent. How should I go about this??
Thanks!
First of all, one plant could be anything from a 12" high dwarf autoflower to a 15 foot high outdoor grown sativa "tree". What "matters" isn't the number of plants per se, but how large they are. In other words, its all about your SPACE.
A 2x2' space is PLENTY big enough to grow a good amount of bud (ie several ounces per crop) assuming you have the right amount of HEIGHT to let the plant(s) grow. You can get away with less, but If you can, I'd say you'd want at least three feet tall for that. Also, if you were growing in a space as large as 2x2x3 you could definitely get in more than one plant if you liked. I'd say up to four if you grew them right.
Good rule of thumb is that optimal lighting is about 70W/sqft for fluorescent lights and 50W/sqft for HPS. You can get away with less, though you'll have less yield and less dense buds.
Not incidentally, fluorescent bulbs can yield excellent dense buds; its just a question of doing it right. You have to use the right spectrum lights, use enough watts light, use reflectors to ensure you're not wasting light, and keep the lights close the plants' canopy. For a 2x2x3 space you could try using a 8 tube 2 foot T5 fluorescent fixture. Something like this:

If you use high output tubes, it will draw nearly 200W of power, and that while less than the optimum, it still ought to be plenty to grow a few plants.
Personally, for a space that large, yeah, I'd go HPS. Look for a 150W or (better) a 250W lamp with reflector. You can pick up a decent 250W unit for as little as $150.
Don't forget about fans for cooling, and odor control.
