I could just control them by switching some lights off in veg and topping every week.
In flower they stretched 3ft 150%.
I need more light, I have a 600w I can add but don’t want to increase the electric consumption that much. I was thinking of taking out the 1000w and putting the 600w in there and getting another 600w but found a deal on Amazon for a 315 CMH for 239$ taxes and shipping in. What is the effective light footprint for yours. I know they are equivalent of 500-600w light. Their info says 6 square feet for flowering 9 for veg.
