Up till now, you have been shielding your plants from a blast of red light to stop stretching, but now your marijuana desires all the photons it can get. Turn your red light spectrum—that’s red and deep red—up to 100%. This maneuver aids you get these greater-than-ever yields.

The rest of the channels in your variable spectrum can remain at 100% as effectively. It is all hands on deck in the flowering stage.

Finishing Stage

This is exactly where you handle your potency and chemical profile. As you recall, blue and white light are the heroes when it comes to creating trichomes. Prioritize blue and UVB at 100%, and turn red down to about 50%. This is how you get these sticky buds absolutely everyone is hunting for.
