Grower guides
Working notes on the science and the craft: what the plant makes, what happens to it after harvest, and how growers argue about method. Written the same way the database is built — specific where the evidence is specific, and explicit about where it runs out.

Terpenes
The volatile compounds behind cannabis aroma, what a terpene number on a label really measures, and where the evidence for their effects runs out.
6 min read
Cannabinoids
THCA, THC, CBD and the minor cannabinoids, how a total THC number is calculated, and why the same flower can test differently at two labs.
7 min read
Genetics and phenotypes
What F1, S1, backcross and IBL actually promise, why two packs with the same name are different plants, and how phenotype hunting works.
7 min read
Trichomes and harvest timing
The gland structures that make cannabinoids and terpenes, how to read clear, cloudy and amber heads, and how much that reading can honestly tell you.

After the cut
Post-harvest
6 guides
Drying and curing
The stage where most quality is won or lost: dry room targets, how to tell when a dry is finished, and what a cure does that a dry cannot.
7 min read
Hash making
Mechanical separation of trichome heads by dry sift and ice water: micron stacks, grading, drying the wash, and why some cultivars simply refuse.
7 min read
Rosin pressing
Solventless extraction with heat and pressure: temperature ranges for flower and hash, bag micron choice, cold cure, and realistic yields.
6 min read
Decarboxylation
The heat reaction that converts THCA to THC, why it costs about twelve percent of the mass, and why a home oven cannot tell you how far it went.
5 min read
Vape carts
What is actually inside a cartridge, why distillate needs terpenes added back, the cutting-agent history worth knowing, and how to read a certificate of analysis.
6 min read
Edibles and infusion
Fat-based infusion, the arithmetic behind a dose estimate, why onset differs from inhalation, and the homogeneity problem that causes most bad experiences.

Crop steering
Using irrigation, substrate and climate to push a plant vegetative or generative, what equipment it actually requires, and when it is not worth doing.
7 min read
Living soil
Growing in a biologically active soil that is fed rather than fertigated: how a mix is built, how it is maintained, and which claims about it hold up.

How these are written
- Figures are given only where they are defensible. Where a number would be invented, the relationship is described instead.
- Disagreement is reported, not smoothed over. Growers contradict each other on most of this, and saying so is more useful than picking a side.
- Nothing here is medical information. No cultivar, cannabinoid or terpene is described as treating anything.
