how do I harden them off? The 2nd pic shows a lot of root I presumed. There fa least 3 inches from root cube.I would allow a few more roots to break through the rooting cube.
Picture 1 isn't relevant.
The appearance of the foliage doesn't indicate a cuttings readiness to veg.
The roots are everything.
When enough roots have broken through,
the cuttings need hardening off
ready to leave the propagator and survive as veg clones.
So do u suggest feedin with water until the plants noticeably start growin vertically?When they begin vigorous vertical growth, vegetation is in progress.
I've been told it's watering approx once every 1-3 days as soon as soil feels dry 2 inches from the top. I thought using coco it was really hard to actually over water because it just drips strait thru?Yes, just don't overdo it on the water.
I don't feed, unless and until the plant starts to show a deficiency. Water as needed.
