imo yes you could do vertical but would need to use either a vertical cool tube or have a really good exhaust fan and a fan on the floor blowing up at the bulb.
I know its an old post but im running a 3x3x5.5 bare bulb but I have one fan blowing up, one extracting, and a 16" room fan cause I sleep in that bitch so I gotta keep it cooooool
I've been rethinking the grow, my closet is only a little bigger than 4' wide so im not sure if I should go with a 4x4 with a 600 or just say screw it and go small untill i get a bigger area. its hard to decide because while theoretically I could do a 4x4, its hard to find a tent that is 72" or shorter with an exhaust vent on the top (i have shelves in my closet that are used for storage and i dont have enough room to move it) and even then i wouldnt be able to maneuver around the tent, only from the front which would be a bitch come late flower. I want to run vertical because the benefits are far greater than horizontal, but it is going to be hard to run a vertical grow in a tent that I can easily work with in my space constraints. I may just run a 150w in a 2x2 until I can run a 4x4 and not have it be more trouble than its worth, and play with a few genetics and learn the growing patterns of each one. As always feedback and criticism is welcome and admired
Yep, for sure, just make sure you control your canopy! I did a 600 in a 4x4 tent, no problem. I'm in a 10x5 now, the extra space is helpful for sure but not necessary. Just makes it easier to work and manipulate etc.
