Nutrient and pH Guide

Maintaining proper nutrient and pH levels can be a challenge, especially for new gardeners. This guide will give you an idea of what you need to do in order to keep your plants healthy.

Nutrients

As a general rule, you will want to use about half an ounce of nutrient solution per gallon of water in the reservoir per week. For example, our Foody 12 towers have a seven gallon base, so you would need to add 3.5 ounces of nutrient solution per week into the base. The exception to this rule is when you're growing vegetables using the Pro Grow formula. The first week you'll use 1/4 the normal amount, and the second week you'll use 1/2 the normal amount. Once you get into the third week, then you'll use the full amount. 

pH Levels

The pH level depends on the type of plant you're growing. You can find handy guides to the specific pH level you'll need for vegetables and herbs using the links. As a general rule, most plants that you would grow hydroponically would have an optimal pH range between 5.5 and 6.5. pH level is important because it affects how well plants absorb nutrients. If the water is too alkaline, then your plants may suffer from nutrient deficiency. Once your plants have matured, the water in the reservoir will gradually become more alkaline over time. This is why it's important to constantly monitor pH levels. An easy way to adjust the pH levels in your hydroponic system is to use a pH kit. Our pH kit includes a pH tester, as well as pH up and pH down. Using a kit such as this will allow you to make sure your plants are properly absorbing nutrients and reach their full growing potential.
