Biological Water Treatment Solution For use soil gardens, soilless mix hydrogardens, and aeroponic growing applications. Containing a mixture of beneficial bacteria including Bacillus subtilis, Paenibacillus polymyxa, Bacillus circulans and Bacillus amyloliquefaciens, Hydroguard bio-fungicide water treatment solution colonizes plant root zones to strengthen and protect plants. Because it forms a barrier against damping-off disease and root rot, Hydroguard is especially effective when used with seedlings and cuttings. Hydroguard is safe for use in soil as well as in hydroponics gardens including aeroponics systems. Directions for use: Soil Gardens: Add 5-15mL (1-3 teaspoons) of HydroGuard per 4 liters (1 gallon) of water. Apply first application to seedlings and re-inoculate every 30-90 days. Soilless Mix Hydrogardens, Aeroponics, and Nutrient Film Technique: Add 5-15mL (1-3 teaspoons) of HydroGuard per 4 Liters (1 gallon) of water. Add to nutrient solution every 7-14 days.
