Pot size for Polar Express

Got some polar express seeds, was wondering if 2 gallon containers would be big enough to grow these in? With such a short growth time I didn't wanna transplant em much and let em grow.

Also curious if it's best to LST these auto flowering plants?

I prefer 3 gal but u could make a 2 gal work. Plant the germed seeds directly into your final pot. Don't transplant autos... they dont like to be stressed.

Oh... and LST is great for autos....

10-4 on the the LST..

I bought 3 gallon smart pots for them... Ive read that a 3 gallon smart pot is equivalent to a 5 gallon plastic
