Yeah I'm using a 15 gallon soft pot and it settled down into the pot after a few waterings. At transplant, I filled it up to the very top but it compacted on it's own. So I added some EWC and more soil.
Ok, huge difference between a 5 gallon pot (my grow) and a 15 gallon pot LOL. Do you add anything else with the soil and EWC, guano, bone meal?
