Nutrient solutions need to be kept below pH7.0 to ensure that every essential nutrient remains available to your crop. However, sometimes the nutrient solution can become alkaline. This can be due to the action of the crop itself as it selects specific nutrients to remove from the solution. Other times it can be due to the use of alkaline tap water, or the use of alkaline fertilizers or additives. As such, the regular monitoring and use of Indica pH DOWN ensures that your nutrient solution always remains in the sweet spot of pH 5.5-6.5.

Indica only use the finest grades of raw materials and reverse osmosis water to ensure the minimum possible contaminants, such as heavy metals which can contaminate inferior industrial acid material. This results in the cleanest possible crop.
