Started from seed in a glass of water/h202 for 24 hours, then transferred to root riot cubes. I put the cubes in a 10x20 germination tray with a humidity dome. It's actually a tray within a tray, the bottom tray having about an inch of water and airstones in it. The idea behind this being that the bubbles from the airstones will help humidity the chamber in addition to the heat mat.
