Ok so i was thinking of cleaning out my closet, and starting a small grow op in it here is a picture of it.

There is a couple things i was wondering. What size light i will need also the cost of the light ill be buying, and how much i can grow in this space. If anyone can help me that would be great. its about 3 and half by 3 and i guess a lower budget would be nice really depends what ill need to get started the less i gotta spend the better and sooner i can get started thanks btw about 6 feet tall

I have about the same space. I would put 4 plants in there with a 400 watt light. You can see how I set up mine here
