Doing well the new quantum board set up is giving them plenty of light. Certainly brighter than the 600w HID. They seem to love it. Just been giving ph'd rainwater and a little cal mag. Gonna feed this week and see what they will do.
@Cherubino, I cant speak to its definite ability as I have never done a side by side with and without it. May try tho on some clones. I would say everything I have fed it to has been super frosty and sticky. How far in flower is the plant you are feeding it?
