Ebb and Flow Growing System
- This system works by temporarily flooding the grow tray with nutrient solution and then draining the solution back into the reservoir, which is controlled by a submeresed pump on a timer
- Several times a day, the timer comes on and allows the pump to release the nutrient solution into the grow tray
- When the timer shuts off the nutrient solution is collected back into the reservoir
- This system can be modified in many ways such as filling the grow tray with grow rocks or gravel
- One main disadvantage of this system is the possibility of a power outage and/or pump timer failures, due to the growing medium that is used
What you'll need:
- Water reservoir
- Pump for fertilized water
- Grow tray and media
- Nutrient solutions
- Air pump and diffuser
- pH and EC/TDS meter, such as the Hanna HI 9813-6
