personally id use the big tent for the photos and use the smaller one to run some good yielding autos just in case a learning experiance happens then in future you could start the photos in the bottom of the auto tent give you a head start on veg time for a couple of weeks then when you harvest the photo tent transplant the new seedlings into bigger pots and you will only need to veg another 2-3 weeks before flipping always wanted to try some master kush almost ran GHS version but ended up with some white rhino that never flowered when will you be popping the master kush
