If it is best to have auto plants on a 24 hours of light and normal strains on a 18-6 hours of light so should I have them in to separate grow rooms or can I have them in the same room and will it hurt my auto plants to be on a 18-6 hours of light
It will not hurt your Autos to run a 18/6 photo period. Personally; I would never mix the 2, but you can grow the Auto’s right beside the regular genetics. Your issue may arrive when you induce flower photo period.
Autos are meant to be run on a long photo period. They are meant to mature quickly, and the more hours of light the more yield. Take it for what it is worth.
