How long do air stones last?

By some reports, airstones begin to lose their effectiveness after about six weeks of use, though this varies depending on the mineral content of your water.

Do I need an air stone if I have a sponge filter?

  • Problems affect plants quicker.

How do I calculate my air pump for hydroponics?

A better rule of thumb is to ensure that the pump you buy will provide at least 500-600cc per minute of air to your nutrient reservoir. 500-600cc per minute is the same as 500-600ml per minute, and even the cheapest air pumps will provide more than that, so most hobbyist indoor gardeners will be safe here.

DO levels in hydroponics?

In hydroponic growing systems, plants are grown in a soil-less environment and receive all essential nutrients from a nutrient solution. Dissolved oxygen (DO) levels of 5 mg/L and above are recommended, as levels below this are detrimental and possibly fatal to plants.
