Superior Potash is a high quality PK booster that will add finished weight to your harvest. It is made using the revolutionary 'Hot Mix technology' which makes the potassium available to the plant in such a way that it can take up more than it actually needs for its metabolic processes. You will notice that your plants stay shorter, stockier and develop denser flower clusters than they do using other PK formulations. When choosing a flowering additive to use in your system a PK boost is considered a must and this is the best there is and should be used as part of any flowering programme where maximum weight is required. NPK ratio 0-9-18 Use at 1ml per litre throughout the bloom cycle.
