This is where the Kratky method shines. It’s a technique that allows you to grow hydroponically without electricity, pumps, or wicks of any kind. In fact, you don’t even have to change your reservoir or add nutrients. It’s as close to a completely “hands off” growing technique as I’ve ever seen. Is air pump necessary for hydroponics?
Deep water culture is the only hydroponic system that an air pump is absolutely required. While not every hydroponic system needs an air pump, you can’t over oxygenate your hydroponic system.
Does hydroponics need moving water?
Stagnant water is not well oxygenated, and that leads to a buildup of harmful pathogens and algae. To protect your plants, the water from the reservoir needs to have air flowing through it. The roots then use the oxygen to better absorb nutrients. Can tomatoes be grown hydroponically?
There are plenty of hydroponic systems that will work great for growing tomatoes, but which one is best for you will come down to how large of a garden you want, and your budget. Growers have used every hydroponic method to grow tomatoes: DWC, Ebb & Flow, Hydroponic Drip, NFT, etc.
How can I oxygenate my water without a pump?
Ways To Oxygenate Fish Tank Without A Pump
- Add live aquarium plants.
- Use a strong filter with an adjustable flow rate.
- Increase water surface agitation.
- Increase water surface area.
- Keep fish that swim in different levels of the tank.
- Water changes/cup method (for emergency situations)
Is more air better for hydroponics?
In a Deep Water Culture hydroponic system, it is absolutely crucial to have adequate oxygen levels because roots are submerged. For optimal growth it is recommended to have 1 Litre Per Minute of air pumped into each Gallon of nutrient solution.

Do you need oxygen for hydroponics?
What is the role of oxygen in hydroponics? … The oxygen actually assists the process of nutrient uptake. When more oxygen is present, plants can better absorb minerals and even water. That means the air stones can make your nutrient solution more efficient.
What size air pump do I need 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.
What is the best Airstone for hydroponics?
The Best Air Stones for Hydroponics in Deep Water Culture (DWC)
- VIVOSUN Air Stone.
- Uxcell Aquarium Fish Tank Air Stones.
- Tetra Whisper Air Pump.
- Active Aqua Commercial Air Pump.
- Pawfly Air Stone Cylinder Bubble.
How long does an air stone 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.
How deep should hydroponics be?
The solution should be deep enough to contain and supply nutrients to the lower plant roots. For example, lettuce plants in 3-inch-deep pots should have no more than 1/16 inch at the bottom of their pots protruding into a nutrient solution about 5 inches deep.
How long should a hydroponic system run?
30 minute minimum on/off time settings will usually be fine, but 15 minute minimums will give you more flexibility. You’ll need a pump timer for any Ebb & Flow (Flood and Drain) system, Drip system, Aeroponic system, and sometimes some people use them in NFT systems as well.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
