my ladies are from a few hermie plants that i have had much success with. I used those seeds, germinated them, and they are now in soil under 400W HPS 18/6... I wanted to use a different space to have other germinating seeds and then during the veg stage and change the other room to a flowering room when the time comes. I was just thinking of getting another 400W HPS for vegetative in the other room.. Will that be good and cause the least stress?
