Ok here’s my up pot method
I use this when starting in a solo cup
These are 16 days from sprout. It’s a water only method. The cotyledons are still green so I hope it’s not to early but the roots are through the weep holes.
I fill my pot with coco/perlite mix with a solo cup in the middle
Remove the solo cup. Nice hole for the transplant
Now I gently squeeze the bottom of the seedling cup, kinda squeezing it up. It will loosen the roots. Turn it out into your free hand and you should have this
Now I plant it into the hole in my new pot. I then do a water only around the base of the transplant.
From here on out, it will be hand watering with whatever nutes I choose. This run is gonna be a Lucas Formula.
Hope this helps anyone when up potting from a solo cup
