I’m almost a pure photo grower, however, auto’s are ready to smoke 6-10 weeks before photo’s every time. Even SoG 4-8 weeks behind an auto.
if you’re running photo seedlings directly into flower, you’re basically auto flowering anyways with chance the plant refuses it and vegetates anyways.
photos advantage comes, in my opinion, if you have a second room. You can infinitely vegetate and dictate the size, style, shape of your plant with good care. If they’ve vegetated awhile, they flip to flower way easier, faster in my experience. Or you can run them as they hit 12-18” SoG style single cola. Then obviously higher THC and yield than auto’s can get to currently and the rotated tents allows you to harvest every couple months. Really 6-12 weeks after you flip any plant out of veg room assuming it has canopy space.
