"About" 150 plants? You don't know...?
LED's and HPS? How do you keep the LED's out of the HID's way? Why the combination? If you've got the HPS, LED's are unnecessary and are in the way.
Rootbound and nutrition will be a problem. (one of many if inexperienced)

Is this your first grow, and which dispensary are you filling?
If this is your first grow...good luck. Hopefully your successes will outweigh your failures. If this isn't a dispensary grow and you are nothing but a scumbag dealer, there are other sites that cater to your kind. If this is for personal...going this big presents a variety of problems avoidable through downsizing and experience.
Rusty Trichome Reviewed by Rusty Trichome on . Question Over Roots? LED Lights and what not! Heh I am growing about 150 autoflowering plants, all various varietes under a combination of led and sodium. they are all potted up in 7" pots at the moment and i really didnt want to disturb their progress but wanted to give the roots a run off. I was going to put all the pots on bread trays elevated from the floor and let the runs run down maybe into a medium like perlite etc? will the roots run down and out or will they just continue to root bound. They are only fifteen days old and Rating: 5
