Don't know when I will be able to transfer to soil and a couple already broke shell, I heard from a buddy that I should wait till their tails get about 2cm before I plant them but I can keep them germinating for weeks if I keep the paper towel wet I've also heard I should plant them asap when they break.
The longer you wait, the higher your chance of damaging the taproot when planted. It can be done best practice is right when you see the root break the shell
5 have already broken and they are pretty long, if I can't get soil today doesn't matter, still have plenty But is there a chance they will survive?
They can survive. Keep warm and wet. Expose them to as little light as possible. Dont sweat it, but get some soil. Lite warior would be my choice in this case. Good luck bro
