oh, i forgot the big plants are 10" and 8", the small plants are around 3-4"

Well how tall is your grow tent and will you have a hps for flower?

grow tent is 5ft tall. and no i dont have HPS, i only got LEDs and CFLs. I cant use HPS for flowering because my reservoir is in the tent, when i did use a 400w HPS, the tent temperature went up to 85 and my reservoir temp climbed to 76.

i am not really worried about vertical space, its more of a length and width problem... (2ft x 4ft), the bigger plants are already touching the mylar and thats before topping and flowering xD. so i think if i top it next week, they will get super bushy (like a furburger), and ill probably have to Nair (trim) the plants to keep it small
