Wipe down the interior walls with warm water and a mild sterilising wash or diluted hydrogen peroxide solution to sweep away any lingering nutrient biofilms or mineral salt scale. Allow the fabric to air-dry completely in a shaded, well-ventilated space before folding it up to prevent storage creasing or mould.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIdeal For (Uses)\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGravity-Fed Irrigation Systems:\u003c\/strong\u003e Serving as the master, zero-power storage hub for automated multi-pot setups that run entirely off gravitational fall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial Facility Nutrient Mixing:\u003c\/strong\u003e Acting as a standalone, easy-to-clean agitation tank where mineral fertilizers, pH buffers, and boosters can be aggressively blended.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestricted-Access Cultivation Zones:\u003c\/strong\u003e Solving water storage logistics in boutique urban spaces, indoor attic setups, or basement tents where standard rigid barrels simply cannot pass through the doors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e","brand":"Holland Forge","offers":[{"title":"50L","offer_id":48424621178980,"sku":"4745","price":99.9,"currency_code":"AUD","in_stock":true},{"title":"225L","offer_id":48424621211748,"sku":"4747","price":151.9,"currency_code":"AUD","in_stock":true},{"title":"400L","offer_id":48424621244516,"sku":"4748","price":227.99,"currency_code":"AUD","in_stock":true},{"title":"750L","offer_id":48424621277284,"sku":"4749","price":313.9,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/50-Litre-SIDE-web.png?v=1778991151","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/aqua-tank-flexible-water-reservoir-series-collapsible-high-capacity-hydroponic-storage","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
