HydroBuddy Hydroponic Nutrient

The HydroBuddy Android app is a complete recoding and port of the popular hydroponic nutrient calculator, HydroBuddy. It contains NO ADS and NO IN-APP PURCHASES.

You can use this calculator to figure out how to combine raw fertilizer salts in order to arrive at a desired concentration of nutrients in a hydroponic nutrient solution. Use it to prepare nutrient solutions by direct addition or to prepare A/B concentrated stock solutions that are then diluted for plant use.
