I have found that prices for a bottle of CO2 can vary dramatically from shop to shop, this side of town to the other side of town. How much do you pay for a bottle of CO2?

The Fallacy of Insuring Minimal Safe Oxygenating RDWC Using Hydrogen Peroxide – They say that if you are really into “cheap oxygenation,” then surely one of the cheapest and easiest ways to oxygenate your nutrient solution is to use hydrogen peroxide (H2O2). They say that H2O2 can particularly...

Root-parasitic fungi: How to control Pythium in hydroponics? By Noucetta Kehdi A dynamic, well-designed growing system, a clean, highly oxygenated water, a well-drained substrate, good ventilation, and the right temperature and humidity levels, are the main ingredients to success when growing...
