Ok,
15 plants(legal state med limit in Wa.)
room size is 8'X12'X9'
3-1000w HPS
2 12"X5" intake vents(no exhaust fans)
1 ceiling exhaust fan, vents outside
5 gallon pots
from the pot they grow to a max height of around 3.5' to 4' and pretty bushy
I attached pics, the veg photo is from my current batch, the week 6 flower is actually from my first batch, I only fed straight water from start to finish. pretty sad but, crawl first. second batch just used all purpose miricle grow, actually a bit better. This batch I used Foxfarm grow big for veg. Cut back the lights on sat. and tomorrow give their first shot of AN iguana juice organic bloom, which will be paired with AN Big Bud in week 2. Already this batch is a shit ton better than grow 1 and 2. The harvest pic is from grow 2.
