I must say that I run a perpetual grow in most of the cab of several varieties maybe 20-30 hashberry at a time. I averaging hb w/plants per and grams per watt. I'm thinking about losing the side mounted t8's for led 50w panels. I could fit anther 30 plants in that way. This system has halved the light bill without the cooling necessary for 800Whps. It has taken a long time to get the best out of flouro tubes. You can see the used car heater core that is supplied by well water in the summer..140f in atttic summer 90-95 in cabinet. Plants grow to touch lights, t12's have 86f surface temp. Some of the cheap shoplight ballasts have failed due to deletion of heatsink on one of the components. Replaced ballast w/GE96hoMVNDIY from homedepot 2 out of 16 fixtures (including veg/clone areas). 24hrs veg 13.5hrs flower. Can't get video to load. Low tech guy new to andriod.
