After a little more research I learned a bit more about converting lux to ppfd. It seems I am in good shape. I'm getting at least 1000 ppfd in all areas of the canopy. Side note, when I have my lights dimmers linked, this isn't the case, the ppfd is always most intense under the center light. By disconnecting the dimmers and running independently, I can dial in the proper intensity to hit a median across the top of the canopy of 70k in the center, the lowest it gets on the sides of the canopy is 50k at the same height. If I drop the lux meter a little lower to the area where my lowest tops are, I am hitting no less than 42k. After converting all this stuff it seems that anything over 40k is sufficient for flower. If I will get the yields I want at 1000ppfd then why put another light in? I am going to put it into the 4x3 with my other spare SF2000, def enough light for that and I can then light it evenly instead of a 2000 and 1000. I'll stick a 1000 in the 3x3 for vegging for 5x5 and a 1000 in 2x2 vegging for 4x3. Then I got a 90w T5 in the bottom of the propagation area/early veg, and 4 20w led strips up above for the seedlings etc. I think this works out nicely... sorry for all the contradiction and bouncing back and forth. Just don't want to fuck myself in the long haul! I may pick up some supplemental lighting for the 5x5 at some point but at the moment I feel like chucking the other SF2000 in there is a waste. Correct me if I am wrong.
