The solid base holds liquid without drainage, making it suitable for reservoir applications where the larger NEF 45L is more than you need. Black construction prevents algae growth by blocking light from reaching the solution inside.\u003c\/p\u003e\n\n\u003ch3\u003eWhere the 23L Size Makes Sense\u003c\/h3\u003e\n\n\u003cp\u003eThe 23L tub sits between a standard bucket and the NEF 45L tub in capacity. For single-plant DWC setups, small recirculating systems, pH and nutrient mixing stations, or cuttings propagation with the \u003ca href=\"\/products\/large-humidity-crib-propagation-dome-hydroponic\"\u003eLarge Humidity Crib\u003c\/a\u003e, 23 litres is the right volume. Large reservoirs can be harder to manage with small systems because the solution-to-plant ratio is too high, making EC and pH harder to stabilise quickly. A 23L reservoir matched to a 1 to 2 plant system gives you tighter control.\u003c\/p\u003e\n\n\u003cp\u003eThe 23L tub also fits inside most grow tents as a mixing or catch container without taking up significant floor space. For growers running recirculating systems that need a separate mixing reservoir distinct from the main system tank, the 23L is the standard choice.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible Accessories\u003c\/h3\u003e\n\n\u003cp\u003eThe NEF lid (sold separately as \u003ca href=\"\/products\/nef-tub-lid-23l-45l-65l-white-hydroponic\"\u003eLids to suit 23\/45\/65L\u003c\/a\u003e) fits the 23L tub for covered reservoir applications.

NEF tubs are manufactured from food-grade plastic suitable for contact with hydroponic nutrient solutions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the solid and grated NEF tubs?\u003c\/strong\u003e The solid tub has a solid base for holding liquid. The grated tub has a perforated base designed as a drainage insert to sit inside the solid tub, creating a flood and drain chamber or root zone aeration layer above the reservoir.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use the 23L tub for DWC?\u003c\/strong\u003e Yes. The 23L volume is appropriate for a single-plant DWC setup. Cut holes in the lid for net pots and an air stone, connect an air pump, and the 23L tub functions as a compact DWC reservoir.
