You don't have to have a doctorate degree in mathematics to hang out here...wouldn't be a liability though! Notice in that above formula from Supra it comes out to about 15 PAR watts a square foot (remember that). IMO you will be a happy camper if you design and build to meet or beat that number with warm cobs...and you will have a very even canopy of photons if you have at least 1 cob per square foot.noobie here.. just joined today and working my way through this thread from page 1 today - incredibly useful info, although my head is swimming with all the acronyms and calcs...
I follow your formula until the last line... where does the 4.65 come from?
Thanks...
No I'm not a mathematics major...but I did read a lot and spent a few nights at a Holiday Inn.
