The drip system seemed to be pretty decent, but I wouldn't go back to it. Thing is that it's complex. A lot more tubing to deal with, 1/8'' ID spaghetti tubing and drippers that clog with salt buildup all too easily. Plus the air pump which was running 24/7 and began to slowly drive me crazy with its noise. What I did like about drip was how it kept its pH and ppm's in check with very little variation. That's not the case with ebb and flow. The pH rises .1 every other day or so and ppms are always on the rise. So to keep things in check I set the pH level down to 5.7 instead of 5.8 and always try to keep the ppms 100 below my target. Demands a lot more attention than drip, but then again the plants grow a helluva lot faster and fuller!
Using a Fearless Gardner air table, I've got my flood times dialed in to 4 minutes on and 3 hours, 56 minutes off - around the clock day and night. The table takes nearly a half an hour to drain, so it's really a 30 minute flood time if you look at it that way. The Eco Plus Commercial Air 1 is a perfect fit btw for the air tables. Just one of these guys is more than enough for powering two tables. Highly recommended!
Flipping the switch to 12/12 tonight. It's time!!!
