From the photos, I’m guessing that you remove the 10 day olds from the Solo cups? I’ve seen some transplants done by cutting away part of the cup to enable the roots to grow through and leaving some of the cup for structural support. Seems to me that removing them from the cup would be preferable. Any advice on how to do that without everything crumbling apart? Do you feed to moisten the Coco before removing from the cup?I start my seeds in root riots and my seedlings always go into solo cups till maybe say day 10 as by then they have great roots and they all have the same coco/clay balls media .I then transplant them into the autopots before then waiting around 10 days till I bottom feed them from the reservoir. Also any questions russ ask away always happy to help
