New and need help

Ok I want to grow like 2 or 3 plants in my closet it is like a 4x4 space, I just need need to know what lights should I get and at the best price?

A 400w hps will do 4 plants in that space nicely. I would splurge for a 600w though. Also, 4ft T5 lighting would also be a possibility. Good luck.

in that space i would go wit a air cooled 400 or 600, and get a fan to suck out hot air, leave the open end of the light hood open, it will help take out tha hot air in your hood and in your grow room
