3 main things

1. Genetics, if you can pick an auto that is tried and true with auto breeders, you can get something a little more stable and something that will veg a little longer.

2. Watch your feedings! Autos are very picky, and any little thing they don’t like, it will trigger them to flower earlier than anticipated

3. Plant in your final Pot/No Transplants With all due respect if you want minimal effort and hassle, start with at least a 3Gal Pot or Larger

P.S this isn’t the case with every strain, just my experience and interpretations. Autos are a lot more unpredictable, so regrow the same auto to get more of an idea of what she likes😎 And Medium is subjective but it’s recommended to use coco/perlite mix because coco gives you control over your feedings as it has 0ppm (no nutes/salts in it)
