Xtreme Gardening 6oz Calcarb Foliar Booster

CalCarb® Foliar Booster is a calcium carbonate spray formulated to deliver calcium and carbon dioxide directly through plant foliage to support nutrient uptake and photosynthesis. Applied to the leaf surface, it penetrates the stomata where it releases usable calcium to strengthen cell walls and carbon dioxide to enhance photosynthetic activity. Suitable for indoor and outdoor use on vegetables, fruits, herbs, and flowers, it supports plant development while helping plants respond to heat and drought stress. Regular foliar application during vegetative and early flowering stages can assist with maintaining plant health and supporting crop quality.
