Any updates on this, don't keep us in suspense here!!
Looks like an amazing setup, although I must say that 7 x 600's is not nearly enough light for a room that size. Assuming your ceiling is 3m high (maybe a bit less)that gives you 27 lumens per square foot. quite far off the ideal 50 per square ft. You need more like 12 600's in there to make ideal use of that space or it's pretty pointless
Without being technical.. 7 is enough for good shit!
Lol
would equate to 75 oz minimum ,,better than a kick in the balls
Best I've had was 72oz from 2 x 600. With 35 sativa seeds started under 12/12.
I always aim for 20oz from each 600 at least.
Best I have had was 47 oz dry from one 600w and 6 x Blue Cheese in 11 ltr pots of cellmax as trees in a 1.2 x 1.2 x 2 meter tent. So 7 600s should still be good.
