NotaNovice,

Thanks for the suggestion

I'm not aiming to use these LEDs in this 1st grow of mine... What I was thinking is that we can try and come up with the best wavelength solution, then order up three or four bulbs... Then, some of us, try this as a side-experiment.

No, you're right... I wouldn't (and won't) replace my HPS/MH with these LEDs for this grow... but if I get my hands on them? Ufff... I'll build another cabinet in one day! Not so much airflow needed... etc. etc. etc...

Thanks for the input Nota!
