*Hydroponics : Comes from Greek, hydro= water, ponos= work. Hydroponics is an old technique that is the art of growing plants in water. Today, hydroponics is a term naming the action of growing plants without soil, on inert substrates. But different inert substrates involve different growing methods (commonly called soilless culture). There are many different hydroponic systems*: drip*, aeroponics*, tidal tables*, NFT*.
*Systems : Means containers of substrates or nutrient solutions feeding plants. Each container operating in a specific way.
*Aeroponics : Not to be confused with aquaponics, aeroponics is a technique of soilless culture. The principle of this type of culture is to spray a nutritive jet (as mist) to provide an environment charged in oxygen for the roots. To spray, and not to water, the nutritive solution on roots, it is necessary to have a pump that can develop a consistent pressure.
*Drip : The system is made of 2 containers. The first container contains the solution; the second contains the substrate (clay balls, coco…) and the plants. An air or water pump, gives the solution on the substrate surface. The solution flows through drips or opened ring. The solution will then water the roots and fall in the first container, and so on.
*Tide table : The principle is to continuously feed plants but they would be fed intermittently. Each watering cycle = one tide. Once the table is full and the substrate sufficiently irrigated, the pump stops feeding the plant with the solution and then it can flow through the drainage holes.
NFT* (Nutrient Film Technique) : The NFT enables the water to circulate continuously at the foot of Rockwool cubes. Water that circulates continuously on this carpet makes a nutrient film.
*CFL : Compact fluorescent lamps that provide an exceptional brightness and save up to 75% of electricity. They are low energy bulbs, last longer and require much less energy than traditional (or incandescent) lamps, and produce the same brightness as them. They also produce little heat.
*Hygrometry : Refers to the relative humidity of air. It is measured using a hygrometer.
*HPS : High pressure sodium bulb. HPS lamps do not function as conventional incandescent lamps. Requiring a particular electric intensity, the sodium bulb cannot function without a plate of adequate wattage (ballast). Its spectrum is ideal for blooming.
*MH : Metal Halide bulb. Its spectrum is ideal for plant growth.
*Ballast : A ballast must be adapted to the type and power required by the bulb. Ballast must be installed by a professional. It is a resistance preventing from overheating bulbs.
*Grow tent : Room made with innovative materials to protect plants from external influences. Enable better control of the plant’s environment. *Reflector : The reflector reflects light in an efficient and consistent way to focus on the plants.
*Réflector : The reflector reflects light in an efficient and consistent way to focus on the plants.
*Substrates : Substrate is a material base that enables receiving an organic element, to ensure sustainability and development
*Aquaponics : Aquaponics is the culture of plants in « symbiosis » with fish farming. The fish excreta are the fertilizer for the cultivated vegetal.
*Stabilized plants : Plants whose sap is replaced by a glycerin based substance, perfectly environmentally friendly and 100% biodegradable. It keeps the plant in the same condition during many years without maintenance.
*pH : Hydrogen potential, pH measures the acidity or alkalinity of a solution.
*EC : Electro conductivity quantifies the richness and concentration of ions in the solution by measuring the conductivity of the solution (most of the nutrients absorbed by the plant are ions when they are in the soil and are ions dedicated to hydroponics fertilizers).
