Constantly circulating nutrient-rich, oxygenated water through each of the four \u003cstrong\u003e20L plant sites\u003c\/strong\u003e drives rapid vegetative growth and strong root development, while all four pots drawing from the same \u003cstrong\u003e120L reservoir\u003c\/strong\u003e keeps EC and pH stable and heads off the uneven growth you get feeding plants separately. Roots suspended directly in oxygen-rich solution absorb water and nutrients far faster than in soil or coco, and the recirculating design keeps that solution moving rather than stagnant - avoiding the weak roots and nutrient imbalances that would otherwise hit bud density in flower.\u003c\/p\u003e\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHighly oxygenated root zone\u003c\/strong\u003e promoting strong, dense root mass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConsistent feeding\u003c\/strong\u003e across all four plant sites from one reservoir\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact footprint\u003c\/strong\u003e ideal for smaller grow tents and rooms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid vegetative growth\u003c\/strong\u003e and improved flowering performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJET-STREAM SILENT 1.0 pump\u003c\/strong\u003e circulating up to \u003cstrong\u003e950 L\/hr\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Black Series components\u003c\/strong\u003e built for reliable long-term use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAssemble the system and connect all pots to the main reservoir using the supplied pipework.\u003c\/li\u003e\n\u003cli\u003eFill the reservoir with water and add hydroponic nutrients to the manufacturer's feeding schedule.\u003c\/li\u003e\n\u003cli\u003eInstall an air pump with air stones to oxygenate the solution (\u003cstrong\u003eJET-35\u003c\/strong\u003e recommended; required for RDWC operation).\u003c\/li\u003e\n\u003cli\u003ePlace plants into net pots filled with clay pebbles or another suitable hydroponic medium.\u003c\/li\u003e\n\u003cli\u003eSwitch on the circulation pump to begin recirculating the solution.\u003c\/li\u003e\n\u003cli\u003eMonitor pH, EC and water levels regularly through veg and flower.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem type:\u003c\/strong\u003e Recirculating Deep Water Culture (RDWC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePots:\u003c\/strong\u003e 4 x 20L per plant site\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem volume:\u003c\/strong\u003e 75L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir:\u003c\/strong\u003e 120L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFootprint:\u003c\/strong\u003e 1.1m x 0.7m minimum, up to 1.36m x 0.96m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant spacing:\u003c\/strong\u003e 50-60cm centres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater pump:\u003c\/strong\u003e JET-STREAM SILENT 1.0, 950 L\/hr maximum flow, 16W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended air pump (sold separately):\u003c\/strong\u003e JET-35, 35 L\/min output, 20W\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Alien","offers":[{"title":"No Tank \/ No Pump","offer_id":52696236065034,"sku":"HYD-ALIE-031-01","price":385.0,"currency_code":"GBP","in_stock":true},{"title":"No Tank \/ With Pump (Jet Stream 950L PH)","offer_id":53409552138506,"sku":"HYD-ALIE-031-02","price":421.95,"currency_code":"GBP","in_stock":true},{"title":"120L Tank \/ No Pump","offer_id":53409552171274,"sku":"HYD-ALIE-031-03","price":500.0,"currency_code":"GBP","in_stock":true},{"title":"120L Tank \/ With Pump (Jet Stream 950L PH)","offer_id":53409552204042,"sku":"HYD-ALIE-031-04","price":536.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/grow-systems-alien-rdwc-4-pot-20l-black-series-29786858782904.webp?v=1773235022","url":"https:\/\/hydrocropshop.co.uk\/products\/alien-rdwc-4-pot-20l-black-series","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
