The larger \u003cstrong\u003e1\/2 in outer diameter\u003c\/strong\u003e moves more volume than 1\/4 in line, which is what you want feeding high-flow GrowoniX systems and long reservoir runs, and it drops straight into 1\/2 in push-to-connect ports with no adapters.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Black RO Tubing Holds Up in Light-Exposed Runs\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe opaque black wall is the point here. It interrupts photosynthesis, so algae can't take hold inside any section of line that sees grow-room light. Most growers run the black on feed and waste runs near the membrane housing where light exposure is worst, and keep translucent white for the spots where they actually want to watch flow. The trade-off is you lose that visual check on water clarity, which matters less on a high-volume feed or waste line than a product line.
