Hi!
Smart pots and other fabric pots are great in general, helping your plants making solid root structure. I just don't like transplanting with them, and now I'll use them to grow autoflowers only (no transplanting).
I'm not convinced by auto pots, mainly because they can't let the soil dry enough and also because I'm not willing to come back to buckets for soil growing.
In the other hand, I would like you to consider Air Pots too. Not easily foldable as the smart pots, but also great for making a good rooting system and transplant are stress free for you and your plant.
