As usual I don’t know how to do moderation, so I have started a lot of seeds over the past couple weeks. They’re in a covered seed tray on a heat mat in the basement, 12 hrs a day of two T5 lights with a bit of “shade cloth” as well. Temps vary between low 60s and mid high 70s in the humidity dome. The cacti/succulents are mostly in 75 or 80% 1/64 – 1/8 inch pumice (Scenic Hill Farms) mixed with 25 or 20% Black Gold cactus mix. Thin layer of fine sifted cactus mix on top, then seeds sown on top.
Update 1/4 — went up to 4 lights but with shade cover, got high T closer to 82 ambient. Also added more water to base to up humidity
1/20 — tried a very slightly acidified solution on the non germinated aztekium / astrophytum.
