ebb n flow in coco works great when you utilize it correctly. Keeping container size small, and transplanting a few times is how i did it. The whole point of ebb and flow is to get that wet dry cycle mulitple times per day. It allows more o2 to the roots. While it is true that its nearly impossible to over water coco, you dont want to keep it wet all the time. You will get better results letting it dry out, sometimes even to the point of wilting a bit as bad as it sounds. With a small enough pot, you are guaranteed to have it dry out 2, maybe 3x per day. I reccommend using perlite in the mix. I always put pantyhose over my drainfitting to block coco particles.
Its has its pros and cons. Ebb n flow uses more water than you actually need per week for any given crop. This is why i have gone to top feed systems. However Ebb n flow offers you more lieninency with salt buildup, and more uniform dispersal of nutrients throughout the root zone. Recirculating reservoirs are more of challenge to maintain, but you can better learn whats going on with your plants by taking reservoir readings. Once you dial it in over time its not too bad. Drain to wasted is less water, less hassle, and damn near fullproof. Thats what i run these days, and im getting my 1g/watt or more no problemo.
