Terms of Service
Last updated: May 2026
These Terms of Service govern your use of this website and its calculators. By using the site you agree to these terms. If you do not agree, please do not use the site.
Use of the calculators
The calculators are provided free of charge for general informational and educational purposes. They run in your browser and are intended to help you plan and estimate, not to replace professional measurement or judgement.
Not professional advice
All results are estimates only. They do not constitute horticultural, agricultural, electrical, financial, medical, legal or other professional advice. Growing conditions, equipment, water chemistry, products and local rules vary, so always verify critical figures and follow the guidance and safety instructions for your own equipment.
No warranty
The website and calculators are provided "as is" and "as available", without warranties of any kind, whether express or implied. We do not warrant that the calculations are accurate, complete, error-free or suitable for any particular purpose, or that the site will be uninterrupted or secure.
Limitation of liability
To the maximum extent permitted by law, we are not liable for any loss or damage — including lost crops, equipment damage, lost profits or other direct or indirect damages — arising from your use of, or reliance on, the website or its results. You use the calculators at your own risk.
Intellectual property
The site design, text, calculators and related content are protected by intellectual property rights. You may use the calculators for your personal or internal business purposes, but you may not copy, scrape, republish or resell the content without permission.
Third-party links and advertising
The site may contain advertising and links to third-party websites. We are not responsible for the content, products, or privacy practices of those third parties. Advertising is provided to help keep the calculators free.
Changes to the service and terms
We may add, change or remove features, and we may update these terms at any time. The date at the top of this page shows when the terms were last revised. Continued use of the site after changes means you accept the updated terms.
Governing law
These terms are governed by the laws applicable at the operator's place of establishment, without regard to conflict-of-law rules. Mandatory consumer protections in your country of residence still apply.
