Yeah, I have used that calculator in the past. It's putting me at 860 ppfd at 24" and like 1150 ppfd at 18". Im liking that.Yeah, he is relatively new, found him a half year ago.
The second link from post # 16 is also useful, as you can directly take over the numbers of the Sammy calculator and convert them to PAR numbers at different heights....
edit: Just tobe sure those numbers are solid, the "area illuminated" means what exactly? I am just using the PPFD they give at the bottom plus 10% losses for reflection. But is it the ppfd for the area illuminated or the umol/m^2/s they use at the bottom?
