This page sets out what the content on Rootwise (zjhbxf.com) is for, and where its limits are. Please read it before using any of the tools. The site holds 22 tools. The site is about: Plant care without the fluff.
Everything here - the tools and the writing - is general information and a learning reference. It does not replace a judgement from a properly qualified professional, and it does not replace an official document, notice or contract term. Any figure a tool produces is a reference magnitude computed from the inputs you supplied. It is not a conclusion, a quote, a diagnosis or a promise.
On health, medicine, medication and nutrition, the site provides checklists and ways of organising information - no dosages, no diagnoses, no substitute for seeing a doctor. Follow your doctor, your pharmacist and the official guidance; where a specific number appears, the official source decides. On law, tax, employment and social insurance, the site explains the basis and the process only, and the formal position of the relevant authority decides. On finance, investment and tendering, the site teaches calculation and process, gives no investment advice, promises no return, and treats every fee as a reference figure. For outdoor, diving, snow, altitude, wildlife, protected-area and border situations, the site provides safety checklists and official contacts only - no decompression tables, no guarantee that any depth or weather is safe, and no way of working around a regulation.
The method behind each tool is explicit. The input data, your understanding of the basis, and the conditions of actually doing the thing are not something a tool can guarantee. Two people get different results from the same tool, the cause is usually a mismatch of basis rather than a broken tool. Put the units, the time window and the definitions in line before comparing anything. Any decision involving money, a signature, a medical check, site work or a promise to somebody else should be re-checked against the original material and the official position.
Advertising on the pages is served by third-party networks; the site neither controls nor endorses what appears there. External links point at public official or reference sites whose content and availability belong to them. They are navigation aids, not recommendations. Their own policies apply.
Some of the writing and data here draws on published statistics, official public information and common industry practice, with sources noted where possible and "check the official source" stated where it matters. If you believe something here affects rights you hold, contact us through the footer and we will look into it.
The site is provided as is, with no express or implied warranty as to absolute accuracy, completeness or fitness for a particular purpose. To the fullest extent permitted by law, no liability is accepted for indirect loss arising from use of, or inability to use, the content here. The "check the official source" notes scattered across the pages are not boilerplate; they mark the edge of what we actually know.
The scope of these terms may change as the service and the applicable rules change. A revised version replaces this page and carries a new date. Questions about any clause can go to the contact details in the footer.
This page is a general disclaimer for the tools published on this site. Watch out for one thing in particular: these tools calculate from the values you supply, so an accurate formula applied to the wrong assumption still gives a confident and wrong answer. Read the result together with the stated assumptions, not on its own.
Where this stops: nothing here is professional advice, and it cannot substitute for an official source, a qualified practitioner, or the terms of a contract. For anything involving health, safety, money, law or engineering, confirm with the relevant official or professional body before you rely on the outcome.
If you are about to run one of the calculators here, a short method helps: step 1, decide which question the tool actually answers and whether your situation is close enough to that question; step 2, enter the inputs exactly as you have them, without rounding them into tidier numbers; step 3, treat the output as a worked estimate and verify any figure that actually matters against the official source. That last step is not optional for decisions involving safety, money or legal obligations.
