By continuously circulating oxygen-rich nutrient solution between every pot and the central reservoir, the system maintains stable root zone conditions and balanced feeding across the entire hydroponic system.\u003c\/p\u003e\n\u003cp data-start=\"500\" data-end=\"990\"\u003eThis RDWC system helps growers maintain consistent EC and pH levels throughout the grow room or grow tent, ensuring plants receive equal nutrients at every site. The constant movement of nutrient solution improves nutrient uptake and oxygen availability, supporting strong plant health throughout vegetative growth and the bloom stage. With well-oxygenated roots and steady nutrient delivery, plants can grow vigorously and produce dense flowers with improved bud density and overall yield.\u003c\/p\u003e\n\u003cp data-start=\"992\" data-end=\"1008\"\u003e\u003cstrong data-start=\"992\" data-end=\"1008\"\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1010\" data-end=\"1463\"\u003e• Large-scale recirculating deep water culture system for high-yield hydroponics\u003cbr data-start=\"1090\" data-end=\"1093\"\u003e• Continuous nutrient circulation ensures consistent feeding across all plants\u003cbr data-start=\"1171\" data-end=\"1174\"\u003e• Oxygen-rich root zones support strong root development and plant health\u003cbr data-start=\"1247\" data-end=\"1250\"\u003e• Helps maintain stable EC and pH across the entire hydroponic system\u003cbr data-start=\"1319\" data-end=\"1322\"\u003e• Suitable for large grow room or indoor growing environments\u003cbr data-start=\"1383\" data-end=\"1386\"\u003e• Supports vigorous vegetative growth and increased yields during flowering\u003c\/p\u003e\n\u003cp data-start=\"1465\" data-end=\"1479\"\u003e\u003cstrong data-start=\"1465\" data-end=\"1479\"\u003eHow to Use\u003c\/strong\u003e\u003c\/p\u003e\n\u003col data-start=\"1481\" data-end=\"2358\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e\n\u003cli data-start=\"1481\" data-end=\"1600\"\u003e\n\u003cp data-start=\"1484\" data-end=\"1600\"\u003eAssemble the RDWC system using the supplied pipework, positioning pots according to the recommended plant centres.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1601\" data-end=\"1727\"\u003e\n\u003cp data-start=\"1604\" data-end=\"1727\"\u003eInstall the JET-STREAM™ SILENT 2.0 water pump to maintain constant nutrient circulation throughout the hydroponic system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1728\" data-end=\"1853\"\u003e\n\u003cp data-start=\"1731\" data-end=\"1853\"\u003eConnect a suitable external air pump (JET-100 recommended) with air stones to supply dissolved oxygen to the root zones.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1854\" data-end=\"1976\"\u003e\n\u003cp data-start=\"1857\" data-end=\"1976\"\u003eFill the reservoir with water and mix hydroponic nutrients according to your feeding schedule for hydroponic systems.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1977\" data-end=\"2109\"\u003e\n\u003cp data-start=\"1980\" data-end=\"2109\"\u003ePlace plants in net pots using an inert medium such as clay pebbles and allow roots to reach the circulating nutrient solution.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2110\" data-end=\"2242\"\u003e\n\u003cp data-start=\"2113\" data-end=\"2242\"\u003eMonitor EC, pH and water levels regularly to maintain optimal nutrient uptake during vegetative growth and the flowering stage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2243\" data-end=\"2358\" data-is-last-node=\"\"\u003e\n\u003cp data-start=\"2246\" data-end=\"2358\" data-is-last-node=\"\"\u003eFor best performance, maintain stable nutrient solution temperatures using a suitable water chiller if required.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Hydro Crop Shop","offers":[{"title":"No Tank \/ No Pump","offer_id":52696230527242,"sku":null,"price":975.0,"currency_code":"GBP","in_stock":true},{"title":"No Tank \/ With Pump (Jet Stream 950L PH)","offer_id":52696230560010,"sku":null,"price":1011.95,"currency_code":"GBP","in_stock":true},{"title":"280L Tank \/ No Pump","offer_id":52696230592778,"sku":null,"price":1140.0,"currency_code":"GBP","in_stock":true},{"title":"280L Tank \/ With Pump (Jet Stream 950L PH)","offer_id":52696230625546,"sku":null,"price":1176.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/grow-systems-alien-rdwc-21-pot-20l-black-series-29786856194232.webp?v=1773240245","url":"https:\/\/hydrocropshop.co.uk\/products\/alien-rdwc-9-pot-36l-pro-silver-series-copy","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
