what you'll need denni, is 3 gallon pots, you can go smaller, but less roots will mean less yeild. growers preference thing.

i use 3 gallon for seed grows (due to veg time to sexual maturity) and 1 litre containers for my clones (which i'll flower as soon as they are 9 inches tall)

what type of hid are you using? if it is mercury vapour, i'd suggest mh or hps.
