DrJynx86answered grow question 4 years ago I never switch off the bloom lights, even when vegging, it's more power for the girls.
The only reason I might switch it off and only leave the veg lights, is for mothers and cuttings/clones, and just if I want to save on the power bill.
They will always grow faster, at any stage, with more watts being delivered, plain math.
Keep on the good care and Happy smokes!
