I just top water it in. Wife got me an ACI auto sprayer. First run I did, but I never let bases go dry now. I keep them full of 6.5ph water from 2 weeks to last days before harvest. My medium stays spongy wet. I know what you’re thinking but the plants don’t care what we think. I run Pro mix but it works great with coco. I use Gia Green amendments, and I top water everything in for several days in a row with no issues. I pull base samples and test PPM, PH but (8-10) week Flowering it hasn’t been a problem. My watering issues have disappeared. No nutrient deficiencies. Several runs in a row with not even a yellow leaf until finish. I just feed the soil the plants feed themselves. Sip buckets are the same principal, but I already have these. My DWC system is still in the box. I’m not saying this is the right way, but it works. A skilled grower with good genetics would get awesome results. There are a few here using them maybe they will weigh in. I have seen top shelf here on those bases.
