Dual Fuel is the newest and most advanced 2 part on the market. It contains no carbonates or synthetic dyes and has the cleanest salt and residue index available. This complex commercial grade formulation has been concentrated in order to reduce volume of nutrients in the grow room. This reduces shelving, storage, handling and plastic bottle waste/disposal. A true ‘sludge free’ two part nutrient solution. When mixed, it will naturally set to pH 6 – 6.5, reducing the need for more chemicals and adjustments.
