The Method

Most cultivation advice is hobbyist folklore. These are operating procedures.

Every protocol here was run, measured, and corrected on a commercial floor — not paraphrased from forums. Substrate formulas with ratios. Fruiting parameters with numbers. Yield benchmarks you can hold a crop against. The same documents we use to train growers and keep a farm consistent.
