Simplifying Measurements

Here are some helpful conversion charts to make sure your measurements are correct. This is often an overlooked area in growing hydroponically or organically. Guessing measurements can cause problems in your plants life cycle. Plants are like people, too much of one thing this is not necessarily good, and not enough of something can cause health problems. Use these helpful measurements with our feed schedules to help you accurately feed your plants.

Garden Management


As with soil-based gardens, hydroponic plants require good pest and disease maintenance controls. Failure to do so creates the same results as with 'ordinary' gardens (i.e. spindly or dead plants). Since the majority of hydroponic plants are fruits and vegetables, that means the plants are not worth eating.

However, managing the hydroponic garden is even trickier, since disease and pests have it much easier in this setting. Plants are continuously kept wet, either immersed in water ('true' hydroponics) or continually sprayed (aeroponics) or reside in a permanently wet medium such as perlite or sand. Fortunately, as with soil-based gardens, there is an large array of available methods to manage the problem.
