Starting a separate veg space, unsure of timing for optimal transition.

Seeds have to grow for 4 to 5 weeks for photos before they can flower. They need the maturing time. So when you have 6 weeks of flower left is a good time to get your seeds going or if you want to take clones for your veg room, take them when the plant are just about to flower. You'll then be ready to move those veggies to the bloom room when your girls have finished. Cheers friend
