Most hemp growers pick the wrong variety for their latitude. The result — crops that flower too early, yields that disappoint, and seasons wasted. HempSeedLatitudeMatcher ends the guesswork.
Hemp is a short-day plant. Flowering is triggered by day length — and day length changes with latitude. A Chinese variety that excels at Katherine, NT (-14°) will fail at Epping Forest, Tasmania (-42°). A European variety bred for temperate conditions will bolt before building biomass in the tropics. The yield loss can exceed 40%.
"Most growers choose varieties based on availability or price. Latitude is the variable that actually determines whether your crop succeeds or fails."
This tool is built on the AgriFutures Australia Industrial Hemp Variety Trials (IHVT) — three seasons, nine sites, 23 varieties, latitudes -14° to -42°. Chinese varieties dominate northern latitudes. European and Canadian varieties dominate southern. Australian varieties bridge the mid-range. That's the science. This tool applies it to your location.
Only commercially available varieties are included. No experimental lines, no research-only genetics — only strains you can actually source, plant, and harvest.
Complete all 6 steps to get your matched varieties. Top 2 results are free. Full access — suppliers, documentation, growing calendar — unlocked with purchase.
Based on your location, soil, and use case
All varieties, seed supplier contacts, legal documentation, and growing calendar are unlocked as part of your Industrial Hemp Science Academy enrollment.
Verified commercial contacts per variety · Country availability · Quarantine requirements · Current stock status
State-by-state permit requirements · THC compliance thresholds · Import permit guidance · Chain of custody templates

Type any city, town, or region — the tool geocodes it automatically and calculates latitude. No manual coordinate entry required.
Soil type is estimated from your geographic zone based on known Australian and global soil classification data, with option to override manually.
23 commercial varieties across Chinese, Canadian, European, and Australian genetics — all validated through AgriFutures Australia's 3-year national trials program.
Instant legal status check and documentation requirements per country — know exactly what permits and certifications you need before you plant.
Fibre, grain, construction, biomass, or dual-purpose — varieties ranked by IHVT performance data for your specific output target and latitude zone.
Version 1.0 of a living tool. The database and matching engine update as new field seasons, commercial releases, and regulatory changes occur.
The tool on its own — or free inside the Academy. The math speaks for itself.
