The smallBoy® This unit is designed to be a stand alone filter for immediate removal of chlorine and sediment from your water. It is rated at up to 99% chlorine removal @ 1 GPM flow and can clean up to 90% of the sediment particles above 5 microns. This filter is not designed to significantly lower the Parts Per Million (PPM} of your water. The majority of the PPM is minerals which can only be removed with Reverse Osmosis. Having chlorine and sediment free water is essential to growing healthy plants and maintaining beneficial micro-organisms, bacteria and fungi in your root zone and growing medium. These microbes can not survive in the presence of chlorine. Chlorine free water is also essential for organic compost tea and extraction solution brewing, hydroponics and any bio-organic gardening method.

Hygrozyme UK’s most popular root stimulant Hygrozyme is a natural enzyme product which breaks down old roots into food for your plants while creating space for new roots to grow. Hygrozyme is completely unique in the way it is manufactured and it contains no living organisms. Hygrozyme can be used right through the entire growing process or as a soak to rid old mediums of dead roots and to prepare them ready for your next grow. Add Hygrozyme to your nutrient solution at a rate of 2ml/litre. Adjust pH as necessary. Use at the same rate for treating cuttings or seedlings and pre-treating rockwool cubes. As with all nutrients, boosters and additives, never mix them together in their concentrated form (i.e. straight out of the bottle). Always add each nutrient, booster or additive to your reservoir or feed water in turn, giving the solution a good stir to mix it in before adding the next one. Hygrozyme is an enzyme product like no other. It is created by an entirely unique fermentation process which produces a bacteria free product consisting of enzymes and amino-acid chains. The enzymes in Hygrozyme break down old roots and turn them into food for your plants. This makes space for new roots to grow into and creates a healthier root-zone. Though it is not certified as organic, Hygrozyme contains only natural ingredients and can be used very effectively as part of a natural feeding schedule. Because Hygrozyme contains no bacteria, the product has an almost unlimited shelf-life and can also be used with peroxide products.
