I love to hear things like this Freak! I remember you from way back at OG right? I was smokinrav back then.
As far as the root development goes, you can plant them most any time a single 1/2" long root has appeared. You can also leave them for months in the rooting jar before planting and develop a large root mass.
Technique is different to transition them to soil though. If you're putting a water clone with small roots in soil, you may need to humidity dome it for a day or two, depending on the RH of the room they're in. Large root masses don't seem to need a humidity dome when transitioning to soil. I don't know why there is a difference. With either method, saturate the soil the clone is going in, and don't amend it to make it too light. Use you're regular medium after they have transitioned. You can use full light 2-3 days after planting.
good thread for people having issues with other cloning methods.
Can I just place clones by the window or do I need to put them under fluoros or some other lightning?
