i hope thats not the case cause i'm gonna try it for myself.. i started today and i'm gonna try to do a journal..but if its shit i'll let people know its shit.. but i'm hoping i didnt just light my $1500 on fire
I really don't think you'll be dissapointed and please post a journal, the more the merrier.
If I can point something really important things about the Magnums (and LED's in general) to help you to dial in your grow quicker and maximize your results. Magnums have 60 degree lenses. Many LED panels have 90 degree lenses and I've even seen up to 135 degree lenses. I think that a lot of LED grows run their panels too high (to get bigger coverage area) so they lack intensity and the plants stretch (looking for stronger light) and waste energy stretching instead of producing. The important thing to understand is 60 degree lenses have half the coverage area but twice the intensity
when hung at the same height as a panel with 90 degree lenses.
I think that hanging the lights at 12-15" is optimal if you are running taller plants and 24-26" if you are scrogging of running lots of short plants that don't need the penetration.
No matter what, LED's just aren't made to light trees as there is a limit to the useful distance of 3W diodes no matter what the lens angle and I think anything beyond 3 1/2 feet from the light isn't usable intensity. If they are being used to grow trees I would side light with additional panels.
You might hear some people say that 60 degree lenses don't allow the spectrums to mix properly but if you do the math on the lens angle and spacing of the LED's in the panel you can quickly figure out that overlap (proper spectrum mixing) occurs at about 5" from the panel so no issues there.
Good luck
