Is growing under only 5000k-6500k cfl's ok or do I need a multispectrum? I am growing lowryder purp gems. I am going with hps for flowering, I was just wondering about the veg state.
So am I understanding correctly that during photosynthesis the plant utilizes the blue spectrum of light, so would it be better to go with all 6500k's or a mix of 6500k's and something closer to 5000k
