Flood and Drain or Ebb and Flow Irrigation for Cannabis Production

Flood and Drain or Ebb and Flow Irrigation for Cannabis Production Professor DeBacco Ebb and Flow Basics Plants are grown in typically an inert substrate that is within a container located in a growing tray where nutrient containing water is pumped from a reservoir into the growing tray. This essentially floods are tray allowing the substrate and roots to absorb some of the nutrient solution before the water slowly drains back to the reservoir. This process also aids in the aeration of the rootzone. Why Growers Like it Ebb and flow systems are easy to automate and are easy to set-up and require minimal parts/equipment. This system is scalable meaning it can be used for 1 or 100’s or 1,000’s+ plants Drawbacks A disadvantage to this system as well as many other hydroponic systems in general is that if something goes wrong (even for a short period of time) the entire crop could be lost. Careful monitoring is essential this includes nutrient concentrations and also pH values Typically nutrient solutions are changed every 7-10 days The system should be cleaned between grow cycles Equipment Needed Reservoir with lid Growing tray to support the plants and hold the flooding cycle Tubing with required fittings Water pump (sized appropriately for size of tray) Timer Plants potted in an inert growing substrate that will allow for absorption of nutrient solution Frequency and Duration How to best run your set-up will depend on a few factors such as… Size/age of plants Substrate plants are growing in General growing environment conditions (Ex. Temp. and Humidity) However a starting point would be… Frequency: Two irrigation events per day during the light cycle Duration: 30min flood cycle Link to Lecture Slides: https://drive.google.com/file/d/1TEgi... 420 Magazine Source Content by Slide Title: Ebb and Flow basics https://www.420magazine.com/community... *Due to the description character limit the full work cited for "Flood and Drain or Ebb and Flow Irrigation for Cannabis Production" can be viewed at... https://drive.google.com/file/d/1stPL...
