I plan on growing Blue Dream autoflower outdoors this spring and summer. Would it be better to plant in 3 gal. or 5 gal. containers?
I would go with the 5 gal if it were me…
5 gal definitely the taller and skinnier pot you can find for Autos is better they like reaching down deep. Also sow your seed in the pot that you plan to Harvest in autoflowers do not like being transplanted most of the time their life span is too short to fully recover from the stress
