The H2OFX Cartridge
H2OFX cartridges come in two different sizes to suit your reservoir or watering container needs. The small cartridge can be used in anything from a watering can to a 40 L (10 gal) water container. The large cartridge can be used in up to a 250L (66 gal) water container.
Add the cartridge at any time throughout the growth cycle – it is recommended for all stages of grow, germination, vegetation and flowering.
