Treating the Reservoir:
Drain a portion of the nutrient solution from the reservoir until the roots are partially exposed. Add the diluted hydrogen peroxide solution to the reservoir, aiming to thoroughly saturate the root zone and nutrient solution.
Duration of Treatment:
Allow the hydrogen peroxide solution to remain in the reservoir for about 30 minutes to an hour. This allows time for the peroxide to react with pathogens and pathogens and oxygenate the nutrient solution.
Flushing and Monitoring:
After the treatment period, flush the system with fresh, clean water to remove residual hydrogen peroxide and any decomposed organic matter. Monitor plants closely for any signs of stress or adverse reactions.
Precautions and Considerations:
Protective Measures: When handling hydrogen peroxide, wear gloves and eye protection to prevent skin or eye irritation.
Avoid Direct Contact: Direct application of concentrated hydrogen peroxide to plant roots can cause damage. Always dilute it appropriately before application.
Frequency of Application: Limit the use of hydrogen peroxide treatments to occasional use as needed. Regular use may disrupt the balance of beneficial microbes in the hydroponic system.
Monitoring and Observation: Observe plant health closely after treatment. If symptoms persist or worsen, reconsider the treatment approach and consider other measures such as improving oxygenation or adjusting nutrient levels.
Other Steps to Treat Root Rot
To effectively treat root rot, hydrogen peroxide should be used in conjunction with other measures:
Identify and fix the root causes – improve aeration, lower water temps, sanitize equipment
Prune away severely damaged roots before treating
Introduce beneficial bacteria to outcompete pathogens and promote healthy roots
Maintain optimal nutrient levels and pH to support plant health
