Many argue that the density of photons is more important than the spectrum. When in flowering, 600-900 PPFD is what I usually aim for. Which grow light(s) are you using?
@Mr. Grow It I have viparspectra 1200 LED with veg and bloom switches.
@rakerbaker I'd run both switches on for the entire grow and just adjust the light distance as needed.
@Mr. Grow It thanks so much that’s what I thought. I have a degree in plant science (40 years ago) and I have learned a ton more watching your videos, thanks for all your hard work!
