Do some of your plants look a tad droopy during the hot days of summer? Heat can sap the energy from a plant. Heat can also heat up and warm the water (nutrient solution) in your containers. That may not be good. Warm water has less oxygen. Adding hydrogen peroxide will help you compensate for lower oxygen levels. That can be good.
H2O2 has an extra atom of oxygen. The release of this extra oxygen in your nutrient solution can result in healthier plants and root systems. You can buy the product in almost any pharmacy, drug store, and places like Costco. Buy the 3% variety. The label should include the words purified water.
Dosage: As a starting point, add four tablespoons per gallon or one cup per twelve gallons each week or add two to three ounces per day per five gallons, which is a tad over a quarter-cup. Always start with a lower dosage to prevent burning. If you notice browning on the edges of leaves you have used too much.
The optimal temperature range for your nutrient solution is 65 to 75 degrees F.
Summer heat can dramatically increase that range and, as a result, tomatoes and other varieties will start to shut down their production of fruit.
H2O2 can help increase the amount of oxygen in your containers. But use caution: heavy dosages of the product can be detrimental. It can kill your plant.
