Liquid Oxygen 1L

Liquid Oxygen contains 17.5% hydrogen peroxide H202. Hydrogen Peroxide is a molecule which is fundamental to life itself, participating in all the metabolic processes in plants and animals. When added to the nutrient tank it will quickly break down into pure water, releasing the extra oxygen atom into the solution where it can be taken up by the roots in much the same way as nutrient ions.

Cleanup
Liquid Oxygen can be used to clean and sterilise the hydroponic system and growing medium. It is a powerful and very aggressive liquid and it will effectively kill all pathogens and harmful bacteria. If using a medium such as Perlite or expanded clay, remove as many of the old roots as possible. Then soak the medium in a concentrated solution of Liquid Oxygen. This will oxidise organic matter in the medium and assist in its rapid decomposition. Remember to flush medium thoroughly with fresh water before re-use. To sterilise a hydroponic system make up Liquid Oxygen in the tank and circulate it around the system to sterilise all the pipe work, drippers etc. Once again remember to flush the system thoroughly with fresh water, or wait a few days, before installing new plants. For cleanup solution: to each 10 litres of water add 100 ml Liquid Oxygen.

Attention
Liquid Oxygen is highly concentrated. The active ingredient is a volatile and aggressive chemical. Treat Liquid Oxygen with great caution and handle with due care. KEEP OUT OF REACH OF CHILDREN
