The roots will grow through that white fabric pots from what I've seen, if we don't move up to the one gallon fabric pots before that completely happens
Royal gold tupur is the medium it's a coco coir pre buffered mix that has perlite in it, the solo cups are bottomless and they are in one pint fabric seed starters
These were planted on wed and it's sat.
All they've had is pH 5.8 distilled water (ppm 0)
The nute chart says feed. My buddy says they'll burn if the roots don't establish first. I've heard it both ways about ppm 240-400 is safe if they have their first true leaves they're photosynthesizing...
