Look at those beautiful ripening fruit, once I've harvested them all I'll be able to make one whole espresso!
What was your method? I have been able to get them to root with construction sand and water but I can never get my greenhouse to stay warm enough for a proper stalk to survive. Rockwool has been even worse on the temperature control front, sadly, I might eventually have to try submerging it in water temperature controlled like a fish tank.
