I am only getting additional light at dusk otherwise it is synced up good. I am going to try and keep one Godfather, Chiquita Banana and Purple Haze, as well as the one labeled Northern Lights Auto in the greenhouse. The other six go into the ground. My question is do I wait longer to transplant outside if they are not root bound and doing well. They are 30 days in the 3/4 full 5 gallon pots. For now I see no reason to not keep the additional lights synced up with my daylight schedule. There is not much heat given off these fixtures to make a diffence.
