I've had fantastic success with Rapid Rooters. Consider them a soil less medium. I add a tiny drop of bloom fert and cannazyme (at maybe 1/10 strength) to some water and pH balance to 6 or so and soak them. I use
Clonex rooting gel but any rooting hormone should work fine. Squeeze the excess water out of them before you place the clone. When you squeeze gently water should not pour out. Moist not wet.
When I place the clone in the hole I carefully tear a piece of the rooter off from around the rim and stuff it in as a shim to support the clone and eliminate air from getting to the new root zone.
I use an inset tray with spaces for the rooters, a regular tray and a dome and only do a dozen or so at a time. I'll fill the middle two rows of the inset with clones and pour a little water on the outside grooves of the bottom tray to keep humidity up.
I mist them immediately with a Vita-Grow Anti Wilt solution but I don't think that's necessary. Be sure to check on the regularly as they have a tendency to absorb too much water if there's too much in the tray. Don't be afraid to squeeze them gently with the clone in to get excess water out.
In summer I use a 75 watt equiv. CFL on 24 hrs and mist with at least once a day without a heat pad. In winter they'll take 3 or 4 times as long without a heating pad. My quickest mom roots in 5 days and most of the rest go 7-10 but I do have a couple real stubborn ones that go 12-14.
Sorry for the long winded response, hope it works out great for ya
