Hey DGC,

To be up front, power consumption and/or big large bud yields are not my concern. I use solar energy and grow only personal bud. What I do care about is tasty terpenes and great medicine. I’m cool with it being super sticky for extract or not for straight smoking fat joints. So resin production is a thought I’m messing around with.

I am using two 315 CMH 3100s in my grow tent. Am I right to assume that if each bulb gives off 1.6 umols/joule and that I am pushing out 3.2 umols/joule total. Which is better than the RSECP 550 LED thats hitting only 2.6 umols/joule. Also somewhere I read that a 315 CMH is equivalent to a 600W HPS. Is this True? Does that potentially mean that I’m pushing the equivalency of a 1200 HPS? If so the 550 is the equivalency of a 1000W HID. I don’t know what any of this means I just want to grow some DANK! Please help me understand what kind of power I am dealing with and how to tame these beast. BTW I’m rocking these in a 3x3x6 grow tent.

Also with all the cool new talk about changing spectrum and/or photo-period time from 12/12 to 18/6 the last week or two of flower positively stressing the plant. What do you think would happen if I put a 315 CMH 3100 WITH a 315 CMH 4100 in the tent the last week or two of flowing? I am able to run both because they do run cooler. (85 degrees for both) My buddy’s RSPEC 550 is dope yet runs a little hotter than just one of my lights. And since I fortunately and accidentally acquired another CMH ballast and and 2 A/C Infinity fans; why not, they rock! Peace and love DGC, I love being a member. The pic is from this grow, my first grow, keepin it real
