Water quality is one of the most important factors when growing plants hydroponically. This is because nutrients in solution can become unavailable due to interactions with salt. Water can also contain high levels of sodium and chloride that are toxic to plants. Botanicare recommends using reverse osmosis (R.O.) water when mixing nutrients, and for hydrating growing media like Botanicare’s Cocogro and Readygro. When you want to grow the best hydroponic crops you have to start with the best water. For more information on how you can get the best water for your plants, please visit our partner, Hydrologic.
A compound that reduces the surface tension of a liquid. Used in hydroponics to help a nutrient solution more easily infiltrate the grow media.
The simplest form of hydroponics is the wick system of fertigating your plants using completely passive methods. In this system, plants draw up the nutrient solution via a fibrous material that is placed in a reservoir. The simplicity of this system is its only advantage because there are no moving parts there is little chance of failure as long as there is water available. The disadvantages of this system are that it does not allow the grower to control rate and frequency of irrigation and during warmer periods the wick system may not be able to keep up with the irrigation needs of the plant. This is the least popular type of hydroponic system and is rarely used at the commercial level.
