  1. LED Grow Lights and the History of Hydroponics Hydroponics has an interesting history. Perhaps the first instance could be traced back to the times of the Romans or even before that when man learnt that plants can be grown with water and some nutrients, without the need for soil. However, hydroponics as it is practiced today perhaps owes its origins to Jean Van Helmont, who, in the 17th century experimented to show that plants draw nutrients from water. www.mvphydroponics.com

  2. After that it was left to Julium von Sachs and W.Knop of Germany to find out that plants use Nitrogen, Potassium and Phosphorus as nutrients. In the early part of the 20th century, Dennis Hoagland developed a nutrient solution the formula of which is still in use. In addition to the three basic nutrients, he also included minute amounts of other metal salts. Then, in WW2, the Americans used hydroponics to grow vegetables on the rocky and barren islands of Iwo Jima and Okinawa.

  3. www.mvphydroponics.com Then in 1960s came along nutrient film technique and drip irrigation system that gave a fillip to hydroponics. Growers used mineral wool and these two techniques to deliver nutrients to plants. A decade later growers of cannabis “discovered” this as being perfectly suited to their requirements. Around this time General Hydroponics arrived on the scene with its ready to use mix of liquid nutrients.

  4. Light is crucial for indoor hydroponics, a practice much preferred by cannabis and marijuana growers. High intensity discharge lamps arrived on the scene and gave a further fillip to hydroponics as did halogen and sodium vapor lamps. However, these were incremental progresses in lighting technology. LED lights used for hydroponics (or any other purpose) last for 100000 hours and have none of the drawbacks.
