These were grown in air-prune beds outside in Rhode Island, so definitely a shorter season compared to indoor starts. I grow them pretty tight to get a lot of trees so they usually grow pretty tall and skinny the first year but they are certainly sturdy. I fall plant half, and spring plant half and they both establish well. The second year typically sees them put more energy into lateral growth with branches and some more height. In good soil and sun I usually get them to fruit by year 6 from seed, sometimes year 5 depending on genetics.
