Roots crawled up in rapid rooters plug.

It is necessary to make the roots not in the light. Make a neat hole in the center and spread it with your fingers, then insert the root carefully and very carefully put in the central hole the middle of the root. So that everything looks like a planted plant, only in a reduced version. The root sticks out in the middle of the soil, the stem is located in the center, vertically. The root is located in the center of the substrate, light does not fall on the root, only the top of the plant sticks out in the middle with leaves up to the light. Do this, transplant carefully, monitor the humidity and roots in the correct position - they will begin rapid growth, after which they will take the entire area of ​​the substrate in a few days 4-7 days with successful good growth. I am also always with seedlings - I cover the sprouts with a lid of transparent passing light, in the first week it is useful to create greenhouse conditions, after the first week and good rooting, you can remove an auxiliary greenhouse. And do not hesitate with a transplant after successful rooting. Good mood and good yields 🙌

Never seen plugs like that before. I would just cover the tops with some peat moss/vermiculte if you have it, or something simlar, to keep the root from drying out. its air pruning itself, so want to act fast.
