I ordered 2 Galaxyhydro 165w. This is good. I'm probably going to integrate a couple 423nm T5 just to **** off my wife. I am sick of wondering when certain T5 bulbs are worn and then tossing them when they still light up but I can't use them for their intended purpose. It just seems like a waste. I welcome all of your destructive criticism. Please make sure to comment on how some white American with a clip board didn't certify that they were safely designed.
