Kreewlanswered grow question 6y ago Hey buddy! The seeds are buried one centimeter in the substrate, and covered with a little bit of substrate. I take a pen with a cap and measure roughly the centimeter, I recommend making it wider than the pen, but not much more. Don't forget to germinate them, sometimes they come out fine but for me it's a lottery if you do it that way. Once the root has come out, place it down in the hole. For me, germinating with plates and napkins is the best, good luck!
