indoor or outdoor?

Ok so i have 6 girls and they are all about 6 weeks old. I have started putting them outside during the day and putting them in my grow room just before dark. There getting 20/4 of light/dark, and there not growing like i wish they would. Should i just leave them either inside or outside or is what im doing better for them. Please help!

Well, you are not hurting them. If you want faster growth then I would say keep it up.
Ya know, if these girls are going to be outside plants in pots it doesn't matter. you got all summer. They will grow to their pot size. If you plan on going in ground and you want monsters then yea the bigger you start them the better chance you will get monsters.
