Its probably mostly the genetics but might have something to do with my light spectrum too as I have 2 4000k and 2 3500k boards in there at 240w. Ive got another 240w but never really felt like I needed it enough to sit down and put it together. I've read a few places the 4000k can add a little frost, might be true.She certainly is frosty!
I had some pulleys for a kayak trolley that I used for my light. Best things ever. Makes raising and lowering super easy.
