I germinated mine in a paper towel, and after they cracked I inserted them into Rapid Rooter plugs and covered the hole up just enough to keep light out. They all flourished in the Rapid Rooters, and I stuck them in the RainForest exactly five days from putting them in paper towels, with roots coming out the sides and bottom. I just put some hydroton in the bottom of the netcups, set the RR plug on top, and filled in around the sides with more hydroton.
