Contact TerraGlass

TerraGlass is a small, independent, ad-supported site — there is no support team standing by, but a real person reads what comes in to support@petpalm.com.

A few things this address is genuinely useful for: a calculator that gave you a result you think is wrong (say which tool — the substrate layer calculator, vessel volume calculator, plant count calculator, humidity guide, moss coverage calculator, or drainage layer calculator— and the values you entered); a tool you wish existed on the site; an out-of-date fact or broken link in the blog, learn section, or the museum; or a bug in how a page looks or behaves on your device.

There’s no fixed response time to promise, and no ticket number or live chat — email is read and handled as it comes in. TerraGlass’s tools produce general planning estimates for a hobby and decor project, not horticultural or veterinary advice, and the site isn’t affiliated with any nursery or plant retailer. If you have a question about whether a specific plant is safe around a pet or child, a vet, poison-control line, or a knowledgeable local nursery will serve you better than this site can.

Before writing in about a tool result, it can help to double-check the numbers you entered — container height, floor area, and plant spread are the most common source of a surprising answer. If it still looks off after that, that’s exactly the kind of message worth sending.
