START HERE: Breeders Lab Rules, Posting Guide & Key Resources

[logic]

Welcome to The Breeders Lab.

This forum is for cannabis genetics and breeding discussion: lineage, parent selection, filial generations, preservation projects, pollen handling, seed viability, trait selection, terpene/aroma inheritance, strain history, and breeder-to-breeder knowledge.

Please read this before starting a new thread.

1. What belongs in The Breeders Lab

Post here for:

• Cannabis lineage, ancestry, and strain history
• Breeding projects, crosses, filial generations, backcrosses, S1/R1 work, IBL work, preservation projects, and polyhybrid questions
• Parent selection, male/female selection, progeny testing, phenotyping, and trait stability
• Pollen collection, pollen storage, seed maturity, seed storage, seed viability, and germination-age questions
• Terpene, aroma, morphology, vigor, resistance, chemotype, and other selectable breeding traits
• Breeder history and old-school cannabis genetics discussion

2. What does not belong here

Do not use this forum for:

• Buying, selling, trading, swapping, testing, giving away, or soliciting seeds, clones, pollen, cannabis, hash, or related items in open forum
• Wish-list posts that are really sourcing requests
• Private sales, begging for freebies, or attempts to bypass site policy
• Spam, affiliate posting, vendor promotion, or repeated commercial links
• Personal attacks, flame wars, doxxing, or posting private conversations
• General grow troubleshooting that belongs in the Cannabis Infirmary or grow-help areas

3. Where should I post?

• The Breeders Lab: breeding, lineage, pollen, seed viability, stabilization, parent selection, preservation, and genetics discussion.
• Strains and Hybrids: general strain opinions, smoke reports, “what strain is this?”, favorite strains, and non-breeding strain talk.
• Auto Flower Strains: autoflower-specific genetics, autos, and auto strain questions.
• Cannabis Infirmary / grow-help forums: plant-health issues, nutrient problems, pests, deficiencies, environment, lighting, and general grow troubleshooting.
• Grow Diaries: step-by-step grow journals and project logs.

4. Make your thread easy to answer

For breeding or lineage questions, include as much of this as possible:

• Strain or line names
• Known breeder, seed source, or origin story, if known
• Generation: F1, F2, F3, BX, S1, R1, IBL, landrace, clone-only, polyhybrid, or unknown
• Your goal: preservation, aroma, resin, vigor, resistance, structure, flowering time, chemotype, yield, morphology, etc.
• Population size and selection criteria used so far
• What traits you are selecting for and what you are culling against
• Photos, test data, germination age, seed storage details, or pollen storage details where relevant
• What you already searched or read before posting

5. Suggested thread title formats

Clear titles get better answers. Good examples:

• [Lineage] Road Kill Skunk history and related lines
• [Question] F2 segregation and selecting keeper males
• [Pollen] Storage method, viability, and timing question
• [Project] First cross: parent goals and selection notes
• [Terpenes] Aroma traits worth selecting for
• [Preservation] Keeping an old line from bottlenecking
• [Vendor/Source Question] First-hand experience only, no solicitation

6. Legacy Breeders Lab resources

These older sticky threads are still useful references, but they are no longer the primary forum index:

• Breeding for beginners
• The Terpenes Of Cannabis, Their Aromas, And Effects
• Collection and Storage of Cycad Pollen
• Nevil's Passing and the start of Operation Green Merchant
