@ClydeGrows, I wasn't sure where to start, great recommendation thank you! Just a question if you don't mind: I'm looking at the ViparSpectra and am deciding between the P600 and P1000. I suppose the most significant difference is the 930 umol/m2/s for the P600 versus the 1006 umol/m2/s for the P1000; would you strongly recommend the P1000 over the P600?
I have a small setup, one plant at the time, and I'm leaning towards the lower wattage of the P600 at the expense of only a small difference in yield (assumingly).
