He gets out what he puts in,so idk about gainful.. Lol..
Heat went up to 80-82 due to the LEDs,but I had an extra in line booster fan and some hose,so I spliced in a hose to the false wall,where its @20degrees or LESS,and hook it into the trigger box with all the venting plugs,so extra a.c. for nothing..I'm thinking it'll be more effecient,but its apparent I won't be able to run all the lamps in the summer..maybe,I'll try,it might help the hood exhaust is tied into the HVAC,in the summer the hoods are cooled with the a.c...
Working so far...
