When starting fresh cuttings, these are typically placed in trays under a dome and watered manually with a hand sprayer. However, we recommend using a tray compatible with an ebb & flood system or capillary matting. This approach not only reduces time and labor, but also ensures a more consistent distribution of water and nutrients. Additionally, it helps avoid plant stress caused by direct water spraying on the plant.

Mother plants remain in the same pot for a longer period, and they typically receive water mixed with concentrated fertilizers. A common challenge is the buildup of high EC (electrical conductivity) in the growing medium. Drip irrigation is an excellent solution for this issue. Each pot is equipped with one or more drippers—small sticks inserted into the substrate, connected to a hose that delivers water from the top. As the water flows through the substrate, it helps wash down excess nitrates, making it easier to control EC levels.

Crops in the vegetative and flowering stages often have short life cycles of about 8 weeks. During this time, they are frequently spaced out or moved to different areas to receive specific climate and lighting strategies. If you're using drippers, it can be labor-intensive to remove and reattach them each time. Additionally, drippers are difficult to clean, increasing the risk of disease and pests.

Because of the short crop cycle, maintaining EC levels is easier due to less buildup. For these stages, an ebb and flood system is highly effective. In this system, crops are placed on a watertight surface that’s flooded with a shallow layer of water and fertilizers several times a day. This ensures each plant receives and absorbs the precise amount of water and nutrients it needs. It saves significant labor, eliminates the risk of clogged or neglected drippers, and allows for a large portion of the water to be drained and reused.

The past years we see a large increasy in use of Nutrient Film Technique (NFT) at large scale cannabis facilities, which we consider also to be a very good alternative for ebb & flood.
