What happens if you use red spetrum cfls like 3000k on a seedling instead of 6500k ?
I don't know exactly but I did that with my first grow and it still grew right and everything but I later switched to 6500k. I wouldn't recommend using all 3000k lights though. They need the 6500k to grow right. I would figure it would just stop growing or take a really long time to grow if only using red spec.
