Greetings, I have read that when the tap root comes out you put the seed with the tap root up , why cause it natural course is to hook and turn down, I did this just to see if what I read was right ahd here is the proof!
View attachment 1819716this blackrose seedling I place in the soil with the tap root pointed up, I have done it both ways, the way to not have the long reach is put close to t5 light, or soak seed in water 24 hr then plant in soil, this is a picture of the soak way.
View attachment 1819717notice the two true leafs are very close to the soil, this way seems to elimate the long reach.
If the seedling do get to long, just prop up with thread and some toothpicks to help them out.
