i take it you dont have the equipment or plants yet, just out of curiousity what strain are you going to grow?
well for starters ur going to need to get ur lights, id say 4 400hps for that space, id go for 11 litre pots too, i use 6.5liitres but i put 16 in a 1x1m tent, so dont want the plants too big but you'll be able to bulk them up bigger than mine, i also top and lollipop all mine(just grow the heads and chop off what the light doesnt really see) to get u started for the next few weeks jus run 2 of the lights as the plants wont need all that light staright away, where are you getting your air from, i drag air in from outside and vent out into my house jus to be on the safe side, and it heats my house up lol
what country are you from, im from the uk and use nutrients only sold here, if you have any questions during the build or wheneva just pop em on here and i'll be glad to help and try and walk you through your first grow, we've all been there,:) hope this helps a little bro
peace hb
