Classy Woman you are Granny.I think you are right, the farther down the tap root can go, most likely the better the plant grows. For me, I don't have enough veg room and have to transplant twice.
And I sure understand not enough time to visit everyone... That is why I don't do my own journals anymore. Dear man, I don't care if you even reply to any of my long winded messages. Just seein you in here brings me joy.
How is that done? Probably a long answer. A link to where you did this would be fine.I also root multiple clones in a single cup of water (no soil til I have roots - but do change/refresh the water every few days) due to not much veg space.
