Demystifying Soil N-P-K Ratios & Nutrient Mobility
Nitrogen (N) drives vegetative foliage growth. Phosphorus (P) fuels root proliferation. Potassium (K) regulates stomatal function. Mobile nutrients like N, P, K show deficiencies in older leaves first, while immobile Ca and Fe appear in new growth.
Understanding Evapotranspiration (ET₀) in Containers
Overwatering rarely comes from too much water per watering; it comes from watering too frequently before soil pores dry out. Saturated substrate cuts off oxygen, leading to anaerobic bacterial growth and root rot (Pythium/Phytophthora).
Inverse Square Law of Sunlight & PAR Levels
Light intensity diminishes by the square of distance from a window. Moving a plant 6 feet from an East window cuts usable Photosynthetically Active Radiation (PAR) by over 75% compared to the windowsill.
