Welcome to SpectraPure Hydroponics Here you will find a wealth of information, not only about the full line of SpectraPure's Water purification products, but, as well, the science behind SpectraPure's world class products. Where did Hydroponics Begin - Wikipedia The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or A Natural History by Francis Bacon, printed a year after his death. Water culture became a popular research technique after that. In 1699, John Woodward published his water culture experiments with spearmint. He found that plants in less-pure water sources grew better than plants in distilled water. By 1842, a list of nine elements believed to be essential for plant growth had been compiled, and the discoveries of German botanists Julius von Sachs and Wilhelm Knop, in the years 1859–1875, resulted in a development of the technique of soilless cultivation. Growth of terrestrial plants without soil in mineral nutrient solutions was called solution culture. It quickly became a standard research and teaching technique and is still widely used. Solution culture is, now considered, a type of hydroponics where there is no inert medium... Nico Escondido, Cultivation Editor at High Times magazine “Most nutrient problems are actually pH problems. For soilless mixtures, use a pH between 6.0 – 6.5. For hydroponic mediums, such as Rockwool or clay pellets, keep it between 5.8 – 6. Warmer roots respire faster, which releases more energy and grows larger root mass and plant size. Keep root temps between 66-70°F.” Here is where SpectraPure can help. With the very best in Media Reactors and Water Purification products to maintain optimum pH levels. Why Hydroponics - Tom Blount, Expert at US Hydroponic Association “Achieve the greatest volume and highest quality of produce possible, while reducing operating costs, and maximizing your profitability by growing smart.” “Just one square metre gives you more yield than in one acre of land. That’s an ideal system for a developing country. [It] will produce up to 300 cucumbers a year.… A system like that can supply a family with fresh vegetables and with vitamins and also with protein” Dr. Nick Savidov, Aquaponics researcher and leader at the Aquaculture Centre of Excellence at Lethbridge College Keith Roberto, Author of How-to Hydroponics. “Hydroponics is the most efficient method of feeding plants through the introduction of pure nutrient salts into the water. When you cut soil out of the equation, you bypass soil-born diseases and the plant’s roots no longer have to search through the soil for nutrients. I like to say you can grow twice as much in half the space. There’s also zero run-off, which means fertilizers don’t wind up leaching through the soil and harming natural water sheds. And everyday garden pests are less likely to take up residence and require the application of costly and sometimes toxic pesticides. Typically, you see a two-to-one ratio of growth over conventional soil.” Needless to say, if you want your growing medium and plant nutrition levels to be maintained at the highest standards, pure water is essential!
