Coco coir biodegradable starter cups/pots

Hello! These aren't bad to start off in, but trust me when I say, they don't biodegrade as fast as you'd like. If you put this pot directly into the new soil during pot up, the roots will become root bound 🙁. We still need to transplant the entirety of the plant into new soil and discard the coir pot. Especially with the round versions. They've been heated, pressed and formed that way and there's less porosity for the roots to travel through the coir, after that process. On a side note, if you haven't started, I wouldn't start them at all in those cups, as roots will attach themselves to the coir and removal for transplant can tear those roots up. I've used Cow pots too (sterilized cow poops heated and formed) but with the same problems. Roots just don't travel through them as well as we'd like them too. That's my personal experience with vegetables and cannabis seedlings. I don't use them anymore unless I'm willing to cut away the coir, cut the roots that are tangled in the coir and do a direct to soil transplant. Hope this helped and please know this is my experience with them, but others may have a better way of utilizing them. Keep the question up and see if anyone gives another answer/suggestion. Cheers! Sorry that was so long
