The bottle of root powder will have full instructions. It helps if the bottom of the stem is damp so that more powder will stick to the stem.
Any of the seed starting mediums and/or vermiculite can be used. I usually keep the pot inside. I have clear bags that I buy for bread that I use to make a little green house. Just put the pot inside the bag, with a stick or old skewer.
Fasten the bag to the skewer with a clothespin. Or you can put a few sticks in the pot and cover with saran wrap. The propagation medium is damp, and covering it keeps it that way without a need to constantly water.
I do leave a teeny space or poke a teeny hole for a little air. Put it under your grow lights.
I use clear paper cups with vent holes on the top and a few around the sides.
