I'm a week in to 12/12. Sending them in to flower. I'm running 3 150w 2800k each. And 2 300w 3900k. Temp is holding around 80 degree they love it. Tomorrow I'm going to start my nuts for flowering. Everything I have said here is it good. Here is some pics.
You see in the picture how the bottom branches seem on the dark side? Usually dark spots dont flower well or have fluffy small buds. Dude at almost three feet already those puppies are gonna finnish huge! Have you seen the way guys use Y spliters in the sockets to plug two of those bulbs into one socket? That would probably be pretty rad over the middle of them.
