Agree, are these grow bulbs? E39 Mogul socket, big ass, 12" to 18" long, big fuckers......
Or just large lamp CFL bulbs?
I got Flourowing reflectors with 125/250 CFLs so if you are using them they too will generate a decent amount of heat...but with all that lighting in that space which... i am calculating to be just shy of 3ft by 3ft, with about a 5ft height....if you train them like hell, they will work, but, you just have no light penetration more than say 2 inches...
Remember, the light is one of the core elements of growing. Nutes are nutes are nutes... growing medium is just a preference. Additives are bullshit.
Light, temp, water, humidity, and a ready supply of nutes. The rest is just sales gimmicks.
If you want to keep the light penetration, high output, and keep temps down.... make the investment into a 315w CMH setup.
I did last year, and I wish I had done it way sooner. Both my 600w MH veg lamps are now 315w CMH but the temps have dropped 10-15degrees (f) and the run in open hoods with a single exhaust in the room now.
I got this one x2 and added bulbs at another 50-60 each. Used my pre-existing 600 setup, just swapped the ballast, popped in the socket adapter, and it was good to go. Wnded up removing the glass from the hood later.
Its a $150 or so investment but its WORTH it. Better color, better light penetration, lower power usage, lower temps.... You will love it. I am moving my flower room to DE CMH 630's over the summer.
