Main Highlights
- Boogie Brew Tea creates phenomenal growth rates while saving the farmer on fertilizer costs & water usage. Nutrients are broken down faster and made more bio-available. Salts & heavy metals found in soil & water supplies become far less hazardous to plants when the enzymes produced by Boogies biological army of organisms work to soften their impact and reduce toxicity.
- Prepare to witness explosive growth, shiny leaf structure, strong root development and awesome flower quality. Used regularly, Heavy Harvest Boogie Brew Tea helps plants to achieve their fullest flavor & aroma potential.
- Why is Boogie Brew so effective? The answer lies in our quality blend of composted Veeganic ingredients. This exceptional recipe blends cutting-edge, natural & non-animal derived fertilizers with concentrated soil conditioners to produce a superior living tea.
- When brewed with oxygen, (actively-aerated) from a strong air pump, this infusion acts as a catalyzing agent, bridging the gap between soil, nutrient and plant. Boogie Brew functions like the probiotics of horticulture: The Soil-Food-Webs own primal defense system!
