A Hydroponic Fertilizer is made for use in hydroponic systems that require a carefully crafted fertilizer to mix into a nutrient solution for crops. Different fertilizers are formulated for different crops. For instance, nutrient-hogging tomatoes will need a very different formula than reserved lettuce. These fertilizers will come either as a liquid or as dry granules, both with pros and cons. The fertilizer is highly soluble in water and it comes on form of dry concentrated nutrients. It provides the best results when used in crops in either hydroponic or even soil grown crops. Hydroponic Fertilizer is very efficient and useful.
