Perfect! I planned for two. So I can run a day time and a night time strain at the same time.
If I got 3 thay would be a bonus but as long as I can fit two photos I am happy.
Depending on the strain, medium used and how you train, 2 will work in a 2x4 tent. Not much head room with lights and exhaust fan hanging. If yours is over 6’ you should have some nice size plants. After 2 months in 2x4 I purchased a 4x8 and had 8 plants. Looked like a forest. I grow hydroponic style and they get big even autos.
Yeh the gorilla tent comes 6ft 11 as standard, with a 1ft extension kit but you can buy a 2ft extension but I dont think almost 10ft will fit in my room lol
