Just watch that 24 to start closely. If someone isn’t supplementing enough calmag the lights will make the plants burn thru them. Lesson learned at the start of my current grow. Once corrected it was all better. I prefer starting at 32 inches and letting the girls grow to the light. So far I haven’t had any stretching issues.
I’m sure a lot of it will be strain dependent. I still don’t understand on my last grow, how I could get an AutoCob to within 10 inches of a the main cola in full bloom, with a reflector on, and there was no signs of stress or burn. Try doing that in veg and watch how fast those leaves curl. I still think we have a few things to learn about how these cobs and plants work together. I’ve never seen anything this efficient when it comes to grow lighting.
@BigSm0 should be proud, and is,
of the light he has put together.
