Expert Eye: Phosphorus

Phosphorus is one of the ‘big three’ major elements that’s vital to the growth and health of plants. It assists in converting the sun’s energy and other chemicals, such as nitrogen, into usable food for plants. A phosphorus deficiency is definitely something that every indoor grower wants to avoid as it invariably leads to sick-looking, stunted plants that produce smaller, lower quality fruits and flowers. Not good! So is the answer to bigger yields simply to pack on the P? Well, it’s not quite as simple as that, so we asked Geary Coogler from BS Horticulture for some expert advice.
