I was thinking the same thing about my plants, so I tested a few males outdoors and with good results they grew faster. Your plants should do fine outdoors unless you live in the Nunivit. You can also build a cold frame for your plants. Just make sure the plant dont roast inside during warm days. That was my big mistake.
Nights around here can get really cold , but it dosent stop my plants from growing. Good luck Mojoke.
