New HPS 400W Watt Hydroponics Switchable Dimming Electronic Ballast For Grow Room Tent Box Cabinet Light System
Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, or coconut husk.
Some of the reasons why hydroponics is being adapted around the world for food production are the following: This auction is for an advanced multi-purpose Electronic Ballast which can support both HIGH PRESSURE SODIUM (HPS) and METAL HALIDE (MH) bulbs.
This particular option gives the grower the flexibility to choose the best selection simply by changing the bulbs, instead of having to own two separate light system setups.
METAL HALIDE bulbs are used to accelerate growth, and HIGH PRESSURE SODIUM bulbs are used to encourage flowering, budding, and fruiting. Our ballasts run on either 120v or 240v without any special rewiring.
Today, hydroponics is an established branch of agronomy. Progress has been rapid, and results obtained in various countries have proved it to be thoroughly practical and to have very definite advantages over conventional methods of horticulture.
The two chief merits of the soilless cultivation of plants are, first, much higher crop yields, and second, hydroponics can be used in places where in-ground agriculture or gardening is not possible.
With pest problems reduced, and nutrients constantly fed to the roots, productivity in hydroponics is high, although plant growth can be limited by the low levels of carbon dioxide in the atmosphere, or limited light exposure.
To increase yield further, some sealed greenhouses inject carbon dioxide into their environment to help growth (CO2 enrichment), add lights to lengthen the day, or control vegetative growth etc.
