General Disclaimer
The information and tools provided by TerraGlass (“https://www.petpalm.com”) are for general hobby and decor purposes only. Everything here is offered in good faith, but we make no representation or warranty of any kind, express or implied, as to the accuracy, adequacy, validity, reliability, or completeness of any information or result on the site.
Any use of the information or tools is entirely at your own risk. It is your responsibility to ensure the results meet your specific requirements and to verify them before acting.
A Planning Aid, Not Horticultural or Safety Advice
TerraGlass’s calculators — the substrate layer ratio calculator, the jar and vessel volume calculator, the plant count calculator, the humidity guide, the moss coverage calculator, and the drainage layer calculator — are designed to help you plan a terrarium build and check your own working. They do not constitute professional horticultural, veterinary, or safety advice, and this site makes no claims about plant safety or toxicity. If a terrarium will be kept somewhere pets or children can reach it, research each specific plant with a qualified source before adding it.
Results Are Planning Estimates
The tools apply standard hobbyist ratios and geometric formulas and round their output for readability. Real terrarium behaviour depends on your specific container, room conditions, and plant choices, so a displayed value is a starting point, not a guaranteed outcome. Always observe your own build over time and adjust.
Why a Result May Look Off
A calculator can return a surprising or blank answer when:
- Units are mismatched: entering a diameter where a radius is expected, or a length in inches where centimetres are assumed, changes the answer entirely.
- Inputs describe an unrealistic setup:for example, a plant spread larger than the container itself, or a coverage fraction outside the 0–1 range.
- A minimum has kicked in: the drainage layer calculator enforces a sensible minimum height for very shallow substrate depths, which can make the result look larger than the raw percentage would suggest.
No Warranty
TerraGlass expressly disclaims all warranties, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that our tools, calculations, or information are error-free or complete, or that the website will be available without interruption.

To the maximum extent permitted by law, TerraGlass shall not be liable for any direct, indirect, incidental, special, consequential, or exemplary damages — including plant loss, project costs, or other losses — arising out of or related to your use of our tools and services.
