what are you getting per 1000w light??

-i'm very interested in learning how much others are getting per light, with what growing medium, and with what nutrient brand.

-my last grow i averaged about 23 oz per light, using the GH flora series, using rockwool cubes in an ebb n' flo system.

please share...

From how many plants is that?

You had a pretty reasonable grow there, its considered good if you get 0.5 g per watt and you managed 0.644g per watt
so good going

My last harvest i harvested one plant under a 600w hps and achieved 15 oz dry weight. Which was 0.51 g per watt

18 plants per 8' x 4' table, 2 lights per table.
