NSCannaanswered grow question 4 years ago I used that tent on my first grow(on my second now) and I put my 4 plants in bloom at 15" inches (soil to top of plant) They grew to 23" (all indicas) which was a pretty good height for the tent, but I starting running into a lot of heat/humidity problems due to my canopy occupying the entire grow space; leaving almost no room for the fans and humidifier. Definitely start training now, if you haven't already, and keep enough space for your gear=)
I ended up moving to a bigger tent, 2 weeks into flower since I was not properly prepared.
