Mid-Size Hydroponic Nutrient Tank Australia\u003c\/h2\u003e\n\u003cp\u003eThe 65L Black Tub Reservoir is a mid-size food-grade black plastic nutrient tank designed for hydroponic systems that need more capacity than a 45L tub but do not require the full volume of a 160L or 220L reservoir. Black construction blocks light to prevent algae growth in the nutrient solution. At 65 litres, it suits multi-plant recirculating systems, larger DWC setups, and nutrient mixing stations for 5L to 10L batch preparation.\u003c\/p\u003e\n\u003ch3\u003eWhy 65L Is the Right Size for Many Setups\u003c\/h3\u003e\n\u003cp\u003eThe jump from 45L to 160L is significant. For growers running 4 to 6 plants in a recirculating drip or ebb and flood system, a 160L reservoir holds more solution than the system needs, which makes pH and EC adjustments slow to take effect and increases the cost of nutrient changes between cycles. A 65L reservoir at the same nutrient concentration requires less product per fill, responds faster to pH correction, and is easier to fully drain and clean between grows.\u003c\/p\u003e\n\u003cp\u003eFor growers using the \u003ca href=\"\/products\/flood-drain-trays-black-hydroponic-ebb-flow\"\u003eFlood and Drain Trays\u003c\/a\u003e or \u003ca href=\"\/products\/flo-gro-dripper-system-recirculating-hydroponic-australia\"\u003eFlo-Gro Dripper System\u003c\/a\u003e, 65 litres provides adequate buffer volume without the overhead of a large tank.\u003c\/p\u003e\n\u003ch3\u003eCompatible Accessories\u003c\/h3\u003e\n\u003cp\u003eThe NEF lid range fits the 65L tub for covered reservoir applications.

Cut the lid for net pot holes and air stone access, run an air pump, and the 65L tub functions as a reliable mid-size DWC reservoir.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes a lid come with the 65L tub?\u003c\/strong\u003e No. The lid is sold separately - see \u003ca href=\"\/products\/nef-tub-lid-23l-45l-65l-white-hydroponic\"\u003eLids to suit 23\/45\/65L White\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the shipping weight on the 65L tub?\u003c\/strong\u003e The 65L tub ships at volumetric weight and falls in the Bulky Freight tier at $79.95 for Zone 1 (VIC\/NSW\/QLD\/SA\/ACT) due to its physical size.
