{"product_id":"nef-tub-solid-45l-black-hydroponic","title":"NEF Tub Solid 45L Black | Hydroponic Reservoir, Grow Tub \u0026 Mixing Container","description":"\u003cp\u003eA reliable nutrient reservoir is the foundation of any hydroponic system. Without a stable, light-proof container holding your nutrient solution, everything downstream, from your pump to your plants, is working against inconsistent conditions. The NEF Solid 45L Black Tub gives you a purpose-built starting point. Solid black construction blocks light completely, preventing the algae blooms that cloud nutrient solutions and compete with your plants for oxygen and nutrients. At 45 litres, it holds enough solution to run a multi-plant drip system, a DWC setup, or a flood and drain reservoir without constant top-ups.\u003c\/p\u003e\u003cp\u003eThe heavy-duty injection-moulded walls are built for repeated use in nutrient-rich environments, and the tub can be drilled to accept tub outlet fittings, grommets, and bulkhead connectors, making it a flexible base for custom system builds. Whether you're setting up your first hydroponic system or adding a dedicated mixing and storage container to an existing setup, the NEF 45L tub is a straightforward, durable solution that does exactly what it needs to.\u003c\/p\u003e\u003ch2\u003eHow It Works\u003c\/h2\u003e\u003cp\u003eFill the tub with water and nutrient solution to create your reservoir. Connect your submersible pump inside the tub to feed your irrigation system, or use tub outlet fittings drilled through the wall for gravity-fed or recirculating connections. The opaque black walls prevent light from penetrating the solution, eliminating the conditions that allow algae to establish. The reinforced wall structure handles the weight of a full 45L solution load without flexing or deforming, maintaining a stable, upright container throughout the grow cycle.\u003c\/p\u003e\u003ch2\u003eKey Benefits\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e45 litre capacity for multi-plant systems.\u003c\/strong\u003e Holds enough nutrient solution to run drip systems, DWC setups, and flood and drain reservoirs without constant refilling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack light-proof construction prevents algae growth.\u003c\/strong\u003e Solid opaque walls block all light from reaching the nutrient solution, eliminating the primary cause of algae blooms in hydroponic reservoirs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-duty injection-moulded plastic.\u003c\/strong\u003e Built for repeated use in nutrient-rich, water-based environments across multiple grow cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with hydroponic fittings and outlets.\u003c\/strong\u003e Can be drilled to accept tub outlet fittings, grommets, and bulkhead connectors for custom system integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile across system types.\u003c\/strong\u003e Suitable as a nutrient reservoir, grow tray base, DWC container, flood and drain reservoir, or general-purpose mixing and storage tub.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy to clean and maintain.\u003c\/strong\u003e Smooth interior walls resist residue buildup and clean out quickly between grow cycles.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHydroponic nutrient reservoir for drip and recirculating systems\u003c\/li\u003e\n\u003cli\u003eDeep Water Culture (DWC) grow container\u003c\/li\u003e\n\u003cli\u003eFlood and drain system reservoir\u003c\/li\u003e\n\u003cli\u003eNutrient solution mixing and storage\u003c\/li\u003e\n\u003cli\u003eCustom hydroponic system builds\u003c\/li\u003e\n\u003cli\u003eIndoor grow room and greenhouse irrigation setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity.\u003c\/strong\u003e 45 litres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour.\u003c\/strong\u003e Black (light-proof)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial.\u003c\/strong\u003e Heavy-duty injection-moulded plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction.\u003c\/strong\u003e Reservoir, grow container, mixing tub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility.\u003c\/strong\u003e Tub outlet fittings, grommets, irrigation fittings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication.\u003c\/strong\u003e Hydroponics, DWC, flood and drain, drip irrigation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironment.\u003c\/strong\u003e Indoor, greenhouse, commercial systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Weight.\u003c\/strong\u003e Approx. 1.5 to 2.5 kg (empty)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Bought Together\u003c\/h2\u003e\u003cp\u003eTurn this tub into a complete reservoir with the right fittings.
