Editorial Policy & Standards

How we aim to make greenhouse planning content useful, traceable, and honest about its limits

Our purpose

Sierra Greenhouse publishes educational guides, planning tools, and equipment comparisons. We aim to connect consequential claims to suitable sources, show the assumptions behind estimates, and distinguish general information from decisions that require local knowledge or a qualified professional.

Editorial standards

Evidence and accuracy

  • Prefer primary research, government guidance, university extension resources, standards, and original manufacturer documentation when appropriate.
  • Link material technical claims to sources where a reliable public source is available.
  • Date changing facts such as prices, availability, regulations, and product specifications.
  • Describe uncertainty, regional variation, and important limitations instead of implying one answer applies everywhere.

Authorship and accountability

  • Published material identifies the Sierra Greenhouse Team as its author.
  • The organization is responsible for maintaining content and considering documented correction reports.
  • We do not present unverified individual biographies, qualifications, or affiliations as evidence of authority.
  • Readers can inspect our sources and should independently verify high-stakes or site-specific decisions.

Clarity and usefulness

  • Explain why a choice matters before listing options or products.
  • Expose calculator formulas, inputs, units, and practical constraints.
  • Separate observed facts, manufacturer claims, estimates, and editorial interpretation.
  • Prefer actionable checklists and comparison criteria over unsupported claims of superiority.

Our publishing workflow

  1. 1

    Define the question

    We identify the reader decision, the facts needed to support it, and the areas where geography, time, or individual circumstances could change the answer.

  2. 2

    Gather sources

    The editorial team looks for current, relevant primary material and records source links near the claims they support. Secondary sources may provide context but should not override a more authoritative primary source.

  3. 3

    Draft with assumptions visible

    Guides and tools should state their scope, assumptions, units, and limitations. Product pages should distinguish our comparison from seller or manufacturer statements.

  4. 4

    Check and maintain

    Before publication, we check links, citations, calculations, disclosures, and internal consistency. After publication, new evidence or a specific reader report may trigger another review.

Source selection

Sources we prefer

  • • Government and public-agency guidance
  • • University extension publications
  • • Peer-reviewed research
  • • Standards and code-setting bodies
  • • Original product manuals and specification sheets
  • • Current retailer pages for dated price or availability snapshots

Sources that need caution

  • • Marketing copy without supporting documentation
  • • Undated or anonymous material
  • • Anecdotes presented as universal outcomes
  • • Aggregated summaries that omit the original source
  • • Old specifications for products that may have changed
  • • Automatically generated claims without source verification

Product comparisons and affiliate links

Some links may earn Sierra Greenhouse a commission without changing the reader's price. The possibility of a commission does not establish that a product is suitable for a particular reader.

Comparisons should use disclosed criteria and link to primary specifications where possible. Prices, stock, warranties, and seller terms can change, so readers should confirm them directly before purchasing.

We do not imply hands-on testing unless the page explains what was tested and how. Manufacturer- or retailer-provided information is identified as such when it supports a material claim.

Corrections

If you find a possible error, send the page URL, the specific statement, and any supporting primary source. We will review documented reports and update material when the available evidence supports a correction.

  • • Typographical and formatting errors may be fixed without a note.
  • • Material factual changes should include a dated correction note.
  • • Product snapshots may be refreshed when specifications or availability change.
  • • A disputed claim may remain while evidence is incomplete or contradictory.

Important limitation

Sierra Greenhouse provides general educational information. It does not replace a site assessment, product label, local code, permit requirement, or advice from a qualified horticultural, structural, electrical, legal, financial, or other professional.
