Product description
Matrix K20 5 L – chloride-free potassium in volume for flowering rooms
If you add potassium to every flowering tank in a room, or run several tents in bloom at the same time, the 1 L bottle empties quickly. The 5 L can of Matrix K20 is five times the volume, the largest size Fenix MTX makes, and lowers the cost per litre.
Why growers use it
K20 is a fast-acting single-nutrient potassium supplement from the German Matrix MTX range. Potassium strengthens cell tissue, regulates the stomata and so the water balance, and supports nutrient transport. The manufacturer also points to better flowering readiness when potassium is topped up during bloom. The formula is chloride-free, so it does not add unwanted salts to your feed, and it is quickly absorbed.
Dosing in big tanks
Use the amounts in the Matrix MTX feeding schedule printed on the label; no fixed ml/L is published online. In large reservoirs, a dosing pump or graduated cylinder makes it easy to add exactly the same amount to every batch. Add K20 together with your base nutrients, stir well and check EC and pH, since every extra element shows up in your EC reading.
Storage
A can this size often lasts more than one season. Keep it closed, frost-free and out of direct light, and shake it before every use. Decanting into a smaller bottle for daily work keeps the bulk sealed.
