sog and scrog are best methods for closet growing

Get a good ventilation System in there
-intake fan (from outside or a/c'ed room)
-exhuast fan (in to attic or out of house)
-dampers on intake and exhuast
-scrubber for odors
-duct mufler for noise

good ventilation could cost around 500.00 and a cheap one maybe 200.00

get some good lights in there
-400w air cooled hps hood runs for 400w but will be worth it (run exhuast duct through hood)

if the closet is tall enough split it in to 2/3 and 1/3 sections
-1/3 section for mothers and clones
-2/3 section for flowering stage

just pick the best looking female from your first harvest


most importantly get yourself a good strain ... spending a grand on a primo closet grow and growing bag seed is pointless. Get a good strain from the seed bank that grows short
