I have two of these led grow lights in this 2x4 and looks to be loving it. I have had red/blue/purple led grow lights for YEARS and so happy to finally get some full spectrum white light action going on.
It is much easier to spot issues with plants now that I can actually SEE THEM in their natural light. With blue led grow lights for example. It is really hard to tell if anything is yellowing because you can't see it in that spectrum.
These are also not too expensive ( around $80 a pop ) and I might even try and cram one more in this 2x4 grow tent. I am going to test the light intensity and canopy coverage with a few light meters I have.
I also have a watts-up meter to test the actual wattage draw from the wall for one, two and then 3 of these mars hydro led grow lights.
Once again, thank you for watching and I am sending positive growers karma to everyone reading this! The AardVark
