The top-feed enhancing growth significantly in the first 2 weeks when your plants have just sprouted. Bubbleponicsīubbleponics takes the same idea of basic DWC (Deep Water Culture) with extra top-feeding/top-dripping where nutrient solution from the reservoir is pumped directly over the seedling’s roots. It is important to ensure and maintain the right amount of nutrient solution for water and oxygen access to the roots. It’s not efficient for larger fruits bearing like tomatoes, peppers, and cucumbers. You will need a large container and more frequent monitoring to grow plants that tend to grow larger. This method works best with fast-growing leafy green plants like lettuce, spinach, and herbs. The roots are partially exposed to the air for oxygen while the remaining parts of roots are immersed in the solution to get nutrients. In this passive system, you leave space for air between the water (nutrient solution) surface and plants’ roots. This is the most basic type of hydroponics with minimal equipment and without any use of electricity. The Kratky Methodĭeep Water Culture without any pump is known as the Kratky Method. As the plant grows, the roots will travel through the Hydroton and net basket and grow directly into the nutrient solution thus providing the plant with a perfect ratio of nutrients and air to promote vigorous root and plant development. The net pot is suspended over a nutrient-rich solution that is aerated with an air pump attached to an air stone. Without vigorous aeration, submerged roots would rot and die – but when the bubbles are constantly present some surprising results often transpire! Basic Deep Water CultureĪs its name implies, the roots of the plant are submerged in “deep water” nutrient solution that is aerated by the air pump.
