I have 3 inch. The only place of issue is the return line from the t at the back. I have seen a significant reduction in flow near the end of my grow.Pretty much my entire question. What size pvc are you using? Are you having clogging problems?
It really does amaze me when things are adjusted and it’s like boom , what the hey.It was kind of cool to see your leaves perk up when you lowered the EC. They are looking awesome man, I have a feeling this will be some killer bud.
I also run two pumps , the main for flow and then a bit smaller for my falls, which is t’d and plumbed with shut offs , so that I can also use it to pump out most everything. The cc buckets are nice but too pricey with there bottom that would allow for a most 100 percent removal were I might have 2 gallons in the ribs.Pretty much my entire question.
