I used to h202 dunk, and sometimes still do depending on seed age, but it was more me just trying to use the soul we use for our native plant grow operation. They require way less loamy soil. Actually most thrive in the shitty stuff.
I’ve had some bugs in the last soil and didn’t want to risk reuse of it without a good sterilization. I transplanted the one survivor into a good mix I finally aquired, hoping he does well. Looks a bit shriveled but still some good green 2nd leaves goin.
