I guess this is bubbleponics? Top-fed RDWC? I am making this shit up. I have a control reservoir on the left with a very small return sump, which is split four ways into three little drippers buried in the hydroton (pulled out to show in one photo) of each bucket. Each grow bucket also has an airstone which are attached to a sizeable airpump rated for a 60-100 gallon aquarium. I repurposed a few Blumat parts I had laying around for the drippers. Thoughts?
