Try to find out how much those plants stretch. You could end up with some crazy ladies at 6 weeks till flip!
Mailining and topping twice are different animals, but you get the picture with how much time it takes. If I'm doin photos after autos, I will start the photos in solos while the autos are half done/finishing up. I start about 5 weeks or so from the autos finishing. Just put them on the edges around the tent. Most times 2 weeks in solos, 2 weeks in a 1 gallon, then a week or so after transplanting into the bed I'll flip the switch. Saves a lot of time with the overlap
