It seems like the dude added far reds (740nm) by adding them as LEDs to his panel! mmm
Sorry but I was mistaken, I think is the same day that those heat bulbs were mentioned by an other member:
great grow, great pics
can i ask if you find the flowering period to be normal or a bit longer with these LED units. i found that the addition of far-red (740nm) leds to a unit seems to reduce flowering time , perhaps the white crees give out some far red?
before my LED units used far red flowering took a week longer than HPS, and with far red they seem to take a week less than HPS
thanks and much respect,

That's interesting.. I think I am gonna think twice when I'll built my fixture, Yes I wanna make my own LED light.
Anyway, I think I am personally gonna try the heatbulb, was even only for the heat? And the UVB ones.
I, At the moment added two 45w cfl's, I hanged them down very low nearly touching the bottom, at the two sides.
My temps, at plants area, went from 67 to 73.50, not too bad.
I too had a oil filled radiator, but on knna thread suggested using cfl and similar... so I thought... that's right..... why should I waste watts on radiator when I can have more light or something?
@captain kron, I have to strongly disagree with what you have said about temps, 78's range is optimal temps for MJ, without Co2 at all; You are right, YOU NEED CO2, but only when you reach 85 - 90 's, but til the 80's, that's a sweet spot for MJ, IT THRIVE.
