Note · 6 minPink Banana Runtz: Early Lessons
I dried and weighed 17.0 oz (roughly 482 g) of flower, plus 4.2 oz of trim for oil. The buds are airier than I’d like but tremendously resinous; the cure is underway.03Reference · 6 minpH and Nutrient Uptake: What Actually Matters in Soil
How pH affects nutrient availability, what a soil reading can tell you, and why input-water pH is not a root-zone measurement.04Data note · 1 minA Quick Look at U.S. Water pH
County medians of 2024 Water Quality Portal pH observations, with an explicit distinction between environmental samples and tap water.05Reference · 5 minVPD Leaf Offset
How leaf temperature changes VPD estimates, why a default offset is only an assumption, and how to compare leaf and air readings.06Reference · 3 minDemystifying DLI
Convert canopy PPFD and lighting hours into daily light integral, with a worked example and practical measurement caveats.07Reference · 2 minWhat Actually Makes a Cannabis Seed Germinate
A failed germination batch, the observations it left behind, and the temperature and moisture checks I plan to improve.08Analysis · 8 min
