So the plants prefer the blue in white light to grow or the red in grolux type light? Just for leaves to grow, no blooming.

ive been doing a bit of research and it seems that 6500k is a good spectrum , i heard blue spectrum can casue algae too. so red is the go.

So far it seems the 5000-6500 K range is best for vegetative growth.
