You need to provide us with more information. Perhaps do a bit more reading. Are you using soil or hydro? HID light? How strong? SOG/SCROG? Do you prefer indica strains or sativa strains. Simply not enough information. I am growing 17 plants in 8 sq feet. You have 9 sq feet.
is screen of green very beneficial? i personally prefer sativa/indica mixes. but i love em all. soil. 400W HPS. dam 18 plants in 8 sq ft? that brings another question. Would it be better to grow like 10 small plants or 4 huge plants? i know all the growing basics i just wanna do it best the first time. keep in mind im growing with someone who has successfully grown before it was just a totally different grow space he used and totally different lights.
heh, glad you took it well, i was just messin around with you. A 3x3 closet sounds small, but im sure if you LST them, and start to flower them early enough you could grow a whole batch of "tomoatoes"
