atomic number 8 is essential for healthy plant development . Although plants generate oxygen as a by - mathematical product during photosynthesis , they require O for vim production during the nighttime . Also , the roots of a plant require oxygen for proper ontogenesis , and bacterium in the rhizosphere use atomic number 8 to transfer N into plant life - available nitrate and ammonium hydroxide . In the soil , tooth root obtain their atomic number 8 from the air that is present in pockets between the soil particles , but in hydroponic organisation , oxygen levels may rapidly drop below the required level of 8 mg / 50 ( fig 1 ) .
Under utmost low-toned - atomic number 8 anaerobic conditions , bacterium start to generate energy by the oxidation of nitrate into nitrite , especially at a low pH. When nitrite accumulates in the substratum , this can quickly reach levels that are toxic to the plant . Plants that are disclose to dangerous levels of nitrite show root browning , leafage wilt , and impair growth . Growth inhibition particularly occurs at low-down pH level : the lower the pH of the irrigation pee , the high the growth limitation . It is therefore crucial to prevent anaerobic conditions by wield sufficient atomic number 8 layer at the root zone .
Intra Hydro pure is a singular silver - stabilize disinfectant based on hydrogen peroxide that slowly decomposes after response in weewee and atomic number 8 . Next to effective water disinfection , this newspaper shows that the addition of Intra Hydro pure to irrigation pee increases the break up oxygen concentration to a stable floor that keeps plant life healthy .
Intra Hydro pure increases the amount of resolve oxygenTomato ( Lycopersicum esculentum ) was seeded on water - gazump rockwool plugs and place under 17 hours of luminousness per daytime . germinate seedlings were reassign to pumice stone stones in a hydroponic culture organization contain plant food water supply with or without 40 ppm Intra Hydro pure . The plants were grown for 5 weeks under 17 hours of visible light per daytime . body of water without Intra Hydro pure contained 40 – 50 % dissolved oxygen . The plus of 40 ppm Intra Hydro vestal increase dissolve atomic number 8 to a stable story of 100 – 110 % within one minute ( material body 2 ) . The plant grown in weewee with and without Intra Hydro stark had a comparable appearance , but the roots maturate in 40 ppm Intra Hydro pure were visibly longer ( fig 3 ) .
At a commercial-grade Gerbera grower , the irrigation body of water from six different drippers was sampled five clock time in a time full point of 14 months ( Figure 4 ) . These measurements clearly show that a higher amount of Intra Hydro pure in the irrigation water correlates with a higher grade of dissolved atomic number 8 .
