I like to float the seed for a maximum of 24 hours. They will usually crack open before then. Quickest I've had one crack open is 6 hours. Once I see the seed has cracked open, I plant directly into medium (coco coir/perlite) temps are ~70°F and she has a dome over her.
I am using reused coco mix. Alot of roots were left behind. This shouldn't create any issues. At least, it hasn't in the past. I probably should have rinsed and buffered. 🤔 I've gotten away without it before. 🤞🤞🤞
She's up a day later than beans normally pop up, but she is alive, nonetheless! Tomorrow will be day 1! 😊
