Hi,
I wanted to know some techniques to prevent root bourne illnesses such as pythium in an ebb and flow system. After suffering from this problem a few times I am sure poor drainage caused much of my problems, coming from NFT, where this was never a problem, I am having a tough time with ebb and flow and pythium.
I am using flexible plastic pipes to drain the nutrient soup from my tray to my reservoir. Problem is, sometimes the pipe goes below and than above the reservoir in height before ending into the reservoir, thus every time a fill and drain occurs, some fluid is left in the flexible drainage pipe. If my timer is filling and draining only twice a day, I am concerned pythium might grow in the warm fluid stuck in the pipe. Is this a real concern? My last 2 failed grows I am thinking were due to left over fluid left in the trays from poor drainage, I plan to fix this promptly, but I am now concerned about the drainage pipe.
