Have you noticed a lot of extra fan leaves/larf? I seem to grow a ridulous amount of leaf with these lights hopefully that transfers to increased yield.
well I am just getting back into the swing of things after 20 years, so I don't have much of a basis for comparison. the girls are definitely growing thick and lush with vegetation. very much like I remember it being like back then. but back then I was using a 400 watt metal halide light next to a 250 watt high pressure sodium light.
last week I cut a ton of leaves off the girls and I could have cut more! they are a week away from harvest now and will be getting straight water in their res later today.
