I think a lot of people want these. Has anyone have the info as to when they will be available ? Has anyone settled for something different? If so...what? Is the difference between 3000k and 4000k that big ? Gratefully growing 3000
Yes the difference is significant. 3000k is more for flower, 4000k Veg. Ideally you'd want both, your plants will respond well being exposed to as wide range as possible not to mention things like 630nm, far infrared, and UV.
