Community Contributions: How Users Help Build the Database
Learn how to contribute strains, write reviews, and help build the most comprehensive cannabis database through community collaboration.
Table of Contents
The Strain Database is not just a product we maintain β it is a living resource shaped by thousands of contributors worldwide. While our AI systems discover and enrich strains at scale, some of the most valuable data in our database comes directly from the cannabis community: growers who know their strains intimately, patients who can speak to real therapeutic effects, and breeders who want their genetics accurately represented. This article explains how you can contribute and why your knowledge matters.
The Submission System
Our submission page is the front door for community contributions. Whether you have discovered a strain that is missing from our database, want to correct information about an existing strain, or have a breeder to add, the submission system provides a structured way to contribute.
Submitting a New Strain
When you submit a new strain, we ask for the following information:
- Strain name β The official or most widely recognized name
- Breeder/seedbank β Who developed or released this strain
- Strain type β Indica, sativa, hybrid, or ruderalis
- Genetic lineage β Parent strains, if known
- Effects β What effects does this strain produce? Select from our 240 effect categories
- Flavors β What does it taste and smell like? Choose from our 405 flavor profiles
- THC/CBD ranges β Cannabinoid percentages, if available
- Description β Any additional context, growing notes, or history
You do not need to fill in every field β partial submissions are welcome. Even just a strain name and breeder is enough to trigger our AI enrichment pipeline, which will attempt to find and verify additional data from our network of 78+ sources.
Submitting a New Breeder
If you know of a seedbank or breeder that is not in our breeder directory, you can submit them with their name, location, website, and any additional information. Breeder submissions help us expand our coverage of the global cannabis genetics landscape.
Correcting Existing Data
Spotted an error? Perhaps a strain is attributed to the wrong breeder, or the listed effects do not match the consensus experience. Correction submissions are just as valuable as new strain additions β they help us maintain the accuracy that makes this database trustworthy.
The Review System
Beyond structured submissions, our review system allows users to share their personal experiences with specific strains. Reviews contribute a layer of real-world data that no amount of web scraping can replicate.
What Makes a Good Review
The most useful reviews go beyond "this strain is great" and include specific, observable details:
- Effects experienced: What did you feel? How long did effects last? Was the onset gradual or immediate?
- Flavor and aroma notes: What did you taste? How does the smell compare to the listed flavor profile?
- Growing observations: If you cultivated this strain, what was the flowering time? Yield? Any challenges or surprises?
- Medical use: If used therapeutically, what symptoms or conditions did it help with? (Note: we display user-reported medical observations for informational purposes and do not present them as medical advice.)
- Context: What consumption method? Indoor or outdoor grown? Which breeder's version?
Reviews are linked to specific strains and contribute to our effect and flavor confidence scores. When multiple users independently report the same effects, our system increases the confidence rating for those effect associations.
Moderation and Quality Process
Every submission and review goes through a moderation process before it appears in the database. This is not about gatekeeping β it is about maintaining data integrity in a domain where misinformation is common.
Automated Checks
When a submission arrives, our system performs several automated validations:
- Duplicate detection: We check the submitted strain name against existing entries, including common variations and misspellings, to prevent duplicate records.
- Breeder verification: If a breeder is cited, we verify they exist in our directory or flag the submission for manual breeder creation.
- Data consistency: We check for obvious inconsistencies β a strain claimed as "100% indica" with "pure sativa" effects, for example, gets flagged for review.
- Spam filtering: Automated detection of promotional content, bot submissions, and irrelevant material.
Human Review
After automated checks, submissions enter our review queue where team members verify the information against independent sources. For strain submissions, we cross-reference with breeder catalogues, seedbank listings, and our AI enrichment sources. For reviews, we evaluate the specificity and plausibility of the reported experience.
The typical review cycle takes 24 to 72 hours. High-confidence submissions from established contributors may be fast-tracked, while submissions that require additional verification take longer.
Why Community Data Matters
Our AI discovery system is powerful, but it has inherent limitations. It can only find strains that exist on the indexed web. It cannot capture oral tradition, local cultivar knowledge, or the experiential nuances that only come from personal consumption or cultivation. Community contributions fill these gaps in ways that are impossible to automate.
Regional and Heritage Strains
Many strains, particularly landraces and heritage cultivars from regions like Afghanistan, Colombia, Thailand, and Morocco, exist primarily in oral tradition and small-scale cultivation. They may never appear on a seedbank website. Community members with connections to these growing traditions contribute invaluable genetic documentation.
Real-World Effect Validation
Breeder-provided effect descriptions are marketing material. Community reviews provide ground truth β what people actually experience, in their own words, across diverse contexts and consumption methods. This user-reported data helps calibrate our effect associations and provides a reality check against catalog claims.
Growing Intelligence
Practical cultivation data β real flowering times, actual yields in specific conditions, susceptibility to pests or diseases β comes almost exclusively from the growing community. This information enriches our strain profiles with practical utility beyond what any product description can offer. Combined with tools from our partner CannAI, community growing data creates a comprehensive cultivation knowledge base.
How to Get Started
Contributing to the Strain Database is straightforward:
- Visit the submission page to add a new strain or breeder, or to report a correction.
- Browse the strain catalogue and leave reviews on strains you have personal experience with.
- Use the recommendation quiz and provide feedback on whether the recommended strains matched your expectations β this helps us improve our matching algorithm.
- Share your growing observations to help build the practical cultivation knowledge that sets our database apart.
A Call for Contributions
With 50,874 strains and growing, we have the breadth. What we need now is depth β richer descriptions, more community-validated effects, real-world growing data, and coverage of the strains that exist beyond the mainstream seedbank catalogue. Every single contribution makes the database more valuable for every other user.
Whether you are a home grower with experience in a single strain or a breeder with a catalogue of hundreds, your knowledge belongs in this database. Cannabis culture has always been about sharing β sharing seeds, sharing knowledge, sharing experiences. The Strain Database is simply a structured way to continue that tradition at global scale.
