Contact
The address is contact@tanknana.com. Messages are read by a person, and anything that asks a question gets an answer, usually within a few working days.
Corrections are the most useful thing you can send: the plant, the field that looks wrong, and where you saw a different value. A grower's or shop's plant profile is enough. Once the change is in, the record cites it.
Shops: the options for being listed are on the partners page. Write to the same address with the name of your shop and the plants you sell.
