Hey Hazy,
Thanks for the post. Please dont take this as a critic etc. im grateful for Your post.
I have prior had the light closer with autos and this time around wanted to see how it fared with a distance that is more than the various people / charts say use. Kinda like a greenhouse with sup.
The new digital ballast, especially Gavita put out a bit more heat than regulars and using HPS the heat is even "worse" (2c more on average, compared to MH)
There is no doubt, had the light been dropped and moved accordingly to stretch, the development should have been better than it currently is. ie. slightly higher yields, due to an eventually bit more node building and extra energy to the plant, due to closer to lights, which would again have raised some more leaves, which would give even more energy when they get hit by the light.
Compared to Tangs grow, day 5,10,etc. (yes many variabales)
The growth of these, hasnt been wicked nor anything, actually they have quite good (above average) but the questions is, how they would have looked, had they been blasted with "proper" lightning.
All the best and thanks for posting in Sir !
