Distance will vary with many factors. The best method to judge is using the back of your hand test. Put your hand under your bulb at any distance you like. If you can keep it there without much discomfort, your plants will be fine too. Test often at the top of your canopy and keep the lights as close as possible for the best results.

supplements i use is hesi root complex i am gona start to add gold labels nutrition when they turn 3 weeks old.
temp is 25 degres celcius humidity is 45-58
There are five passive inlet air holes at bottom and is outside of tubs sucking exhaust air thru active carbon filter. I thought that cooltube would be great to eliminate heat in this system, but I was so wrong! As you can see from that pic, air doesn't move at the top very well.
anyone see any problems mixing GH with advanced nutes and techna flora nutes? right now i got flora duo base 2 part mixed with av big bid and buf factor x and b -52 for my freinds 1000w 8 plant grow hes broke so i scraped up some old nutes i had and free grow samples from the grow store.but i want to switch the big bud now that he is in week four and i dont have overdrive and i want to replace it with techna floras awsome blossome anyone think thats a bad idea?thanks in advance for anyones info
I'm no expert, but if money is the problem have him try MAXIBLOOM and dry KOOLBLOOM. It's cheap and works well, he should get multiple grows under 40 bucks. Trying to mix and match nutes sounds like a major PITA, here's a link https://www.icmag.com/ic/showthread.php?t=191645
What a great idea! Really gonna try this out if it helps. Thank you!Why not just put the air holes at the top, so cool air is pulled in, goes down through the plants and down to the cooltube opening? You'd probably want some thing to keep light in (and out during dark periods) - maybe some PVC pipe elbows or something similar?
