Germinating in final pot size

Has anyone ever started their seed(s) in their final pot size but had different sized biodegradable cups in the center to act as potting up? Would this not work the same? since roots will first get balled up in the first (peat,coco) cup before breaking down to move to the next pocket?

Hmmm, don’t know about that.

Explain?

Looking at the pic I would say no pots would sit in water making the pot soft and the root would go right through

I can’t, but I think if I was going to use the same pot from start to finish, I’d just plant my seed and let it do its thing. I couldn’t say for sure, but I think your concept might slow down the vegetive growth? Give it a try. Sounds interesting.

I use a solo cup with drain holes and half pearlite with whatever medium I'm using ( hard for me to overwater with all that pearlite ).
I cut in half vertically and tape it back together before I fill it.
That way you can peel the tape and split the cup off really easily. I saw that air pots split like this and was like, hmmm.

You are supposed to transplant so the roots grow out at all levels basically, if you start in a big pot they mostly go down. All those stupid natural outdoor plants, trees and such, doing it wrong That's one reason why people transplant anyway, another is room.

To specifically answer your question, Yes. I used those dissolvable small planting cups on some stuff for the garden. It wouldn't let the roots through like you would think. I had to dig stuff up and peel the cups away. They were degrading, but not as fast as the roots needed them to. It was outside so I was watering pretty good.

Why not just transplant? As stated above starting in small containers works best for proper watering and root ball formation.
