HydroLogic Tubing 3/8 inch - 50' Black – Black

Hydro-Logic 3/8 Black Tubing for Clean RO Water Routing Hydro-Logic 3/8 black tubing gives you 50 feet of flexible polyethylene line for moving filtered water between your RO unit, reservoir, and feed points. The 3/8" OD line runs neatly along walls and benches, so you can keep the reservoir area tidy instead of fighting kinked, tangled runs. Its opaque black wall blocks light inside the tube, which helps keep algae from taking hold in the line over a long grow. Sizing 3/8 Reverse Osmosis Tubing for Evolution-RO and Merlin-Garden Pro This 3/8" reverse osmosis tubing matches Evolution-RO and Merlin-Garden Pro systems, so replacement runs seat cleanly on the same quick-connect fittings. Growers usually keep the run from the RO output to the float valve as short as practical. Extra length adds friction and slightly lowers delivery pressure. Keep a spare 50-foot roll on the shelf. Worn or stained lines swap out in minutes when you re-route around pumps, chillers, or tight corners. Key Features 50 ft length: Gives you room for re-routes, expansions, and cleaner installs across the grow room. 3/8" OD polyethylene: Flexible PE wall bends around corners while holding consistent fitment on compatible RO connections. Opaque black wall: Blocks light inside the line to discourage algae from building up over a long run. Evolution-RO and Merlin-Garden Pro fit: Direct replacement line for these systems on the same quick-connect fittings. Bagged 50-foot roll: Spare line stays clean on the shelf for fast repairs and system tweaks.
