Although it is perhaps one of the most overlooked aspects, pH is very important in hydroponic and organic as well as regular soil gardening. pH is measured on a scale of 1-14 with 7 being neutral.


Acids are lower than 7 and alkalis (bases) are above 7. This article deals with the pH of hydroponic gardening and the availability of nutrients at different pH levels in a soilless growing medium. Organic and soil gardening have different levels, so the following chart doesn't pertain to them. To be technical, the term pH refers to the potential hydrogen-hydroxyl ion content of a solution. Solutions ionize into positive and negative ions. Pure water has a balance of hydrogen (H+) and hydroxyl (OH-) ions and is therefore pH neutral (pH 7).

The pH scale is logarithmic, which means that each unit of change equals a tenfold change in the hydrogen/hydroxyl ion concentration. GENERAL HYDROPONICS: pH Dynamics And Adjustment. Answer: pH is the measure of acidity/alkalinity of a solution.

Growing different plants with similar requirements will help ensure the best growth. The concentration of nutrients is measured as Conductivity Factor (CF). The more nutrients dissolved in the solution, the more conductive it becomes. Aquaponics. A small, portable aquaponics system.


The term aquaponics is a portmanteau of the terms aquaculture and hydroponic agriculture. Aquaponics (/ˈækwəˈpɒnᵻks/) refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrifying bacteria initially into nitrites and subsequently into nitrates, which are utilized by the plants as nutrients, and the water is then recirculated back to the aquaculture system.
