should i throw this clone in soil yet?

i cut them 3 weeks ago yesterday, and put em in small rockwool piece i cut. i used rooting gel and all that.
if i tug the stem a little, i cant pull it out at all, so i know there is SOME root structure in the rockwool. its just not showing itself yet. i was thinking of putting them in a dixie cup with soil. i would bury it to the bottom set of leaves.

think thats a good idea? or should i wait more? its been 3 weeks for both of them

update: i just took one out to look, and theres a single root coming out the bottom of the rockwool!

what a coincidence i asked this just as it was popping out haha. but id still like to know if i should plant them or not

Wait until the tips of roots are exposed from the cubes.

I agree give it a few more days and get a nice root system going before you transplants them!

ok thanks!

3 weeks of growin a clone you should have a good amount of roots..

yeah thats what i thought. but theyve looked perfectly healthy the entire time so idk haha
