Greetings, I like to experiment, so I started two pots on 7-1, pot #8 sprouted on 7-3, it was in a covered seed tray on a heat mat, 100% pumice. Pot #9 sprouted 7-5, on the open bench, no pre soak. Pot #9 is a net pot with 1:1 pumice/#2 cherrystone, and is in a dish of water, sort of semi-hydroponic. I plan to use dilute 9-3-6 when the true leaves are out. I am curious how well they grow and mature in this substrate.
