Starting seedlings indoors
I've just finished getting the new garden area soil balanced and ready to go all ph levels in great range I am going to start all my seedlings late February and add new seeds every week or so to ensure staggered harvesting. I'm doing them in Pete pellets and domes. I'm going to use heating pads and put them under 400w HPS light in the garage.. Do I put them on 24hr light then when ready temp them or harden as some call it or will the change in 24hrs of light then go to march light from sun make them think it's time to bloom as a supposed to vegg growth? Or is there a better light schedule for seedlings like 18 light 6dark or 12/12 etc? I normally put them in sun room but next year we added a lot more plants to the garden so I need more space so it's a light over sun light to pop them any thoughts on the matter.
