By enhancing cell wall strength and chlorophyll production, it supports vigorous flower and fruit development. Suitable for both flowering and vegetative phases, this nutrient formula ensures healthier, more robust plants with easy-to-use dosing. ## Description Massboost is a plant booster that prevents calcium (Ca) & magnesium (Mg) deficiencies while stimulating powerful fruit set & development. Massboost is used during weeks 3, 5, & 7 in flower to provide increased levels of calcium & magnesium during specific stages of flower development. Calcium & magnesium are often overlooked but are entirely essential for healthy growth in plants. Calcium largely comprises the cell walls of plant cells giving structure to stout flowers, stems, leaves, & an available supply allows the continued formation of new plant tissue during intense periods of growth. Magnesium is the central core of chlorophyll thus essential for the plant to undergo photosynthesis metabolizing sunlight, water, oxygen, & Carbon dioxide into materials allowing the plant to develop. Directions for use: use during weeks 3, 5, & 7 during flowering increasing from 5-10 mlper 5 gallon. Use during the vegetative phase if needed at the rate of 2. 5-5 mlper 5 gallon as needed. ## Features - Massboost is a plant booster that prevents calcium (Ca) and magnesium (MG) deficiencies while stimulating powerful fruit set and development.
