Phenotype hunting

Phenotype hunting: a systematic method

How serious hunters work through a 50-pack to find the one.

2 min read2026-05-2615 views

Phenotype hunting is more than "plant 50 seeds and pick the best." Real hunters score every plant on a structured rubric so they can defend the keeper against the other 49.

The hunter's rubric

1
Vegetative (weeks 1–4)
Score structure, internode spacing, leaf width, vigor, and disease resistance. Cull the obvious losers early.
2
Early flower (weeks 5–7)
Score stretch, branch strength, smell on rub. Take cuttings of every survivor — you'll need clones to verify the keeper.
3
Mid flower (weeks 8–10)
Score flower density, resin coverage, terpene complexity, disease/mold resistance. Cull aggressively.
4
Harvest (weeks 11–12)
Score yield, density (wet → dry weight), and trim difficulty. Take careful tissue samples for the lab if you can.
5
Post-cure (weeks 14+)
Smoke test, terpene retention, harshness, effect duration. The keeper is the plant that still impresses you 4 weeks after the chop.

How many seeds is enough?

Casual hunt

to find a great plant

Serious hunt

to find a special plant

Pro hunt

100+

to find a legendary keeper

These are rough rules of thumb. Stable IBL lines need fewer; wide polyhybrid F1s benefit from larger pops.

Pheno hunting on a budget

You don't need a 100-pack to find a special plant. Small hunts find keepers every day if you run them carefully. The trick is to stop wasting tent space on plants you've already culled.

1
Buy from a documented line
Stable F3+ or IBL lines give a better keeper-per-seed rate than wide F1 polyhybrids.
2
Cull aggressively in veg
Slow, weak, leaf-curled, or visually off plants get pulled at week 3.
3
Take cuttings of every survivor
You can't unflower a plant. The clone is your only shot at running the keeper again.
4
Score on a structured rubric
Pre-write your scorecard: flavor, structure, finish, frost, smoke. Numerical scoring beats vibes.
5
Re-run the keeper
A 'keeper' identified from one run is a candidate. A keeper that survives two runs in different conditions is the real thing.

Phenotype vs genotype

Genotype is the genetic code. Phenotype is how that code expresses under specific conditions. Same seeds, different plants.
