I actually heard from a few different YouTube channels that they use the same dirt over and over. Some added amendments. Some did nothing but start watering with nutrients pretty quickly.
I had six plants for my first harvest. After I cut all the plants at the stalk I put them outside for a few days while I processed my bounty.
A couple of days ago I finished pulling out the rootball and the rest of the stalks. Mixed the dirt (potting soil, peat, and vermiculite) up with each other and packed 3 five gallon pots for my next crop. I plan to start nutrients as soon as I get first leaves. (I plan on growing three plants at a time. I reaped a big harvest, 1.2lbs or so.
