@Hattiwatti, I do interconnected RDWC when i do water culture. I've never had a bad experience with rot or pathogens spreading from one plant through the entire RDWC system, and man i've done my far share over the last 25 years. I think a lot of people are not understanding the importance of keeping the water temps down. No more than 70F, period, End of discussion. We used to put trays of ice cubes in our reservoirs to keep things cool 25 years ago. That may have been a little extreme. Today they have water chillers, though they are stupidly expensive, they will ensure a steady 68F water temps, which the plants will thank you for.
