Improving quality is my whole reason for growing indoors. I could grow all these strains outside in one season. Doesn’t matter if the UV is there during veg or not if you get better finished quality flowers without it then you can change that in an indoor environment and just turn it on when it best serves what you are wanting out of the plant. Just like with the right equipment I can make it spring, winter, or fall in Mississippi at anytime of the year.
