When to plant clones

I took clones about 2 weeks ago and the roots are now about 1/2" out of the rockwool. When should it be safe to plant them

i think i would wait a few more days but i would be putting them in soil. seems like ive seen other posts with more roots poking out before planting but they should be fine. sorry ive never used rockwool but want to try.

Go for it. let your medium be moist.

The more mature they are the less likelyhood of shock. I'd wait one more week and then it's bombs away.
