@Budzbuddha built one using the qb and then re using one of the drivers. But was only able to power qb at 50 watts.... if im not mistaken... so your gonna spend 120 dollars getting it all set up when you could just bury that light and buy a new one that will be much better and will last you 10+ years.... do you want 3 oz a grow or do you want a LB per grow.... the choice is yours. Lol
Correct on the 304 ... which i did not know recently that it was off catalog. However the 50 watt power is the boards “ sweet spot “ since it is at a higher efficiency with these “ mid power “ leds. I grew 4 plants under that lowly one panel and it still blew that old mars door stop out of the water. It grew 4 plants at 5 w / per foot in a 3x3.
And the plants thrived.
Since then I modified to a 3 panel rig ( wing ) that the 304s ... even though they are off catalog , you would have to pull them from my dead hands . I got early matched sets that robin and Stephen used to write the info on the boards. These have been running consistently from dec. 2015 to last month ( since playing with the 96s ) .... the same original mars build is the center. Cooling was a bonus thru the side vents that pointed at wing boards .
And eventually pulled the old drivers for a meanwell swap.
Hopefully they refresh the 304’s and bring them back as a mixed board.
Even though she’s about 4 years old ... she is still one of my workhorses ...
I would appreciate your help
