My six week Obesum seedlings are in a dixie cup. (2 seedlings). About 2" is coir and the rest of the cup is my gritty mix. They are almost 3" out of soil multi leaves. Can't photo right now it's to smokey for me, again. Could they be buried deeper at this point? I like short stalks. We do that with other plants but never read it done here. These are my first seeds to do well.
