My blueberry auto is now flowering should I used only flower switch and veg. Trying to cut down on the heat, I’m only using the flower switch.
The goal for growing is the most light in the temp range.
Managing temp is a priority
Lights with dimmer or multi-mode capability allow for some control.
Sucks loosing lights, but sucks more burning the plant.
If temps allow Veg&Bloom.
When too hot, choose one.
More exhaust with cooler intake helps.
I cant grow indoors from June to Sept. (unless using HLG lights).
Good growing to you.
Also, shift lighting hours to take advantage of “Natural Cooling cycle of earth”.
