It's been in this pot since I purchased him back in July; it's a self watering pot I found on Amazon. I highly recommend them. I have all of my plants in them at this point.

He came in a tiny little plastic pot nested inside a ceramic pot, so he gained quite a bit of root room in his current pot.
I used a mixture of 75% cactus potting soil and 25% standard potting mix and added the peat moss he came with back to the top of the soil.
Not sure if this has been said yet, but you can buy bottom watering pots! It's what I use for all my plants and has been a total game changer for me (previously killed every plant I'd ever owned)
Self watering pot! My T. Zebrina started going downhill and I put her in one when she was still little and I swear I saved her life. Now she’s so big I can’t STOP her from thriving

I carefully pulled the plant out of the AeroGarden. Cut off the plastic, tried not to touch the root.
Filled the planter halfway and dug a small hole in the center.
Spread the roots across the soil, put the plug in the whole and filled with more soil.
Then I watered well and watched to make sure the bottom had water.
I squished it between two AeroGardens so the light would help it take.
I have my Boston and maidenhair in these pots - makes it much easier to keep them moist : https://smile.amazon.com/Watering-Aerating-Reservoir-Succulents-Windowsill/dp/B07998PP1B
Also second the draft/window/cold air tip, I had mine hanging in front of an open window for a while and it did not like that :(
