Ok so if i have a veg room inside, veg for a few weeks and then move them to a greenhouse during the winter for flowering?Will it work? Go auto into flower when its in greenhouse?
It will work out great! The winter time will cause them to flower, and they will flower nicely in the greenhouse. Id suggest to throw a new plant out every week so can start harvesting every week after a few months. Sounds like you will be having a good grow!
I don't exactly know what your talking about when you say go auto (unless thats the type of seed you'll be growing), As for the greenhouse in the winter, You'll need to agument the natural light with artificial light(grow lights), and if your going to do that you might as well keep them inside and happy!
How can anyone answer this question without knowing where the OP is located? How deep into winter? How many hours of light? Light intensity in winter is paltry. It might work, as long as you keep temps in range, but most likely you would need to supplement with artificial light as chimera said.
