What's up JP. Great lookin grow man. +Rep for a detailed and interesting journal. I'm actually in the process of finishing up my cabinet right now, and about halfway through reading your thread i realized i'm using the exact same cab as you. Same light fixture as the one you just bought too with the splitters using 6 23w 2700k bulbs. I've got a few things similar to yours including your issues with heat! lol workin it out myself but had a few questions for you. #1 can you post a pic standing further back with the cab doors open. I'd like to get a better idea of your setup and how big your girl is. #2 what are your ambient room temps outside the cab? just tryin to put it in perspective with mine. As for hanging the light fixture, I just screwed it right into the bottom of one of the shelves that came with it. It fits right in the middle nice and snug and the 5 shelf heights let me raise and lower the light. Not sure if that will work for you cause of how big your girl is tho. Anyways, I would like to post a few pics of my cab once i work a few smaller details out if thats cool with you. Keep up the good grow and remember to be patient, it will all be worth it!
