The O2XS system provides a unique and totally revolutionary system to alleviate the problem of a lack of dissolved oxygen in the nutrient solution for hydroponic growers.
Out stripping the results of all previous techniques (Ebb & Flood, NFT, Aeroponics) the O2XS system super-saturates the nutrient solution through pressure. Allowing a consistently higher level of dissolved oxygen that surpasses saturation point and is maintained under the plants biological demand (BOD). This cannot be achieved in any other hydroponic system on the market today in the world.
The benefits of the O2XSsystem include
* Achieved consistent levels of in excess of 14 mg/l
* More rapid growth as roots have an optimal supply of oxygen at all times
* A stockier, higher yielding plant
* No need for tank changes
* A clean system
* A 90% reduced risk of pythium
* Most system sizes run under 100W
* Lower light levels required
An Introduction To Dissolved Oxygen
All plants have the same basic needs of light, food, CO 2, water, heat and fresh air. By growing hydroponically we have the added advantage of ensuring adequate oxygen to the roots by suspending them in water, allowing them to absorb the oxygen in water rapidly. However, if the oxygen content in the water is inadequate the plant growth will slow in proportion to the oxygen availability. Thus the trick of the hydroponic grower is to co-ordinate the supply of water, nutrient and oxygen with the crops needs according to other environmental factors like temperature of air and water, CO2 levels, ventilation, humidity, moisture capacity of rooting media, size and type of crop and day length.
All of these factors can be manipulated by the grower with the use of lights, fans, heaters, coolers etc.
However until now, one factor could not be manipulated ? the level of dissolved oxygen in the nutrient solution. Dissolved oxygen is vital for the health and strength of the root system as well as being necessary for nutrient uptake, but the rate at which oxygen can be dissolved in water depends upon variables like temperature and pressure.
Put simply, the colder the water, the more dissolved oxygen it can hold and conversely, the warmer the water, the less oxygen it can hold.
As you can see by the table below, water at a temperature of 1 C cannot contain more than 14.19 mg/l of dissolved oxygen, whilst at 28 C it cannot contain more than 7.81 mg/l of dissolved oxygen.
