I am running at 500 watts hps hortilux atm I plan on switching to 750 just after the stretch. 5 plants in a 4x4 tent in 5 gallon pots. 3 Green Gummy, 1 Sweet Afghani Delicious and 1 Chocolope. My roots are coming out of bottom of pots and may be rootbound I vegged for a while because i had to control some cold temps. my question is should I transplant? I switched to 12/12 two days ago. My canopys is absolutely full and everything is very intertwined with my trellis and im running out of vertical space to work with. Another note my plants were on the floor of the tent and maybe the roots are just poking out to drink the drainage?
