By constantly circulating nutrient-rich, oxygenated water through each plant site, this system helps deliver rapid vegetative growth, strong root development and excellent yields.\u003c\/p\u003e\n\u003cp data-start=\"423\" data-end=\"718\"\u003eThe RDWC design ensures all plants receive the same nutrient solution from the central reservoir, maintaining stable EC and pH levels across the system. This consistency helps avoid uneven plant growth and supports healthy development from early vegetative growth through to the flowering stage.\u003c\/p\u003e\n\u003ch3 data-start=\"720\" data-end=\"736\"\u003eKey Benefits\u003c\/h3\u003e\n\u003cp data-start=\"738\" data-end=\"1230\"\u003e• Recirculating deep water culture system designed for fast hydroponic growth\u003cbr data-start=\"815\" data-end=\"818\"\u003e• Highly oxygenated root zone promotes strong root development\u003cbr data-start=\"880\" data-end=\"883\"\u003e• Consistent nutrient distribution across all plant sites\u003cbr data-start=\"940\" data-end=\"943\"\u003e• Compact footprint ideal for smaller grow tents and grow rooms\u003cbr data-start=\"1006\" data-end=\"1009\"\u003e• Encourages rapid vegetative growth and improved flowering performance\u003cbr data-start=\"1080\" data-end=\"1083\"\u003e• Durable Black Series components built for reliable hydroponic systems\u003cbr data-start=\"1154\" data-end=\"1157\"\u003e• Suitable for use with clay pebbles and other hydroponic growing media\u003c\/p\u003e\n\u003ch3 data-start=\"1232\" data-end=\"1263\"\u003eHow It Solves Grow Problems\u003c\/h3\u003e\n\u003cp data-start=\"1265\" data-end=\"1532\"\u003eMany growers experience slow growth and poor nutrient uptake when root zones lack sufficient oxygen. RDWC systems solve this by suspending roots directly in oxygen-rich nutrient solution, allowing plants to absorb water and nutrients much faster than in soil or coco.\u003c\/p\u003e\n\u003cp data-start=\"1534\" data-end=\"1791\"\u003eThe recirculating design prevents stagnant nutrient solution and keeps feeding conditions consistent across all plants. This helps avoid uneven growth, weak root systems and nutrient imbalances that can reduce yield or cause problems during the bloom stage.\u003c\/p\u003e\n\u003cp data-start=\"1793\" data-end=\"1941\"\u003eWith the recommended air pump providing strong aeration, plants develop dense root masses that support healthier flowering and improved bud density.\u003c\/p\u003e\n\u003ch3 data-start=\"1943\" data-end=\"1957\"\u003eHow to Use\u003c\/h3\u003e\n\u003col data-start=\"1959\" data-end=\"2602\"\u003e\n\u003cli data-start=\"1959\" data-end=\"2060\"\u003e\n\u003cp data-start=\"1962\" data-end=\"2060\"\u003eAssemble the RDWC system and connect all pots to the main reservoir using the supplied pipework.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2061\" data-end=\"2174\"\u003e\n\u003cp data-start=\"2064\" data-end=\"2174\"\u003eFill the reservoir with water and add hydroponic nutrients according to the manufacturer’s feeding schedule.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2175\" data-end=\"2281\"\u003e\n\u003cp data-start=\"2178\" data-end=\"2281\"\u003eInstall an air pump with air stones to oxygenate the nutrient solution (required for RDWC operation).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2282\" data-end=\"2385\"\u003e\n\u003cp data-start=\"2285\" data-end=\"2385\"\u003ePlace plants into net pots filled with clay pebbles or another suitable hydroponic growing medium.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2386\" data-end=\"2480\"\u003e\n\u003cp data-start=\"2389\" data-end=\"2480\"\u003eTurn on the circulation pump to begin recirculating nutrient solution through the system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"2481\" data-end=\"2602\"\u003e\n\u003cp data-start=\"2484\" data-end=\"2602\"\u003eRegularly monitor pH, EC and water levels to maintain optimal plant health throughout vegetative growth and flowering.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3 data-start=\"2604\" data-end=\"2632\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp data-start=\"2634\" data-end=\"2777\"\u003e• System type: Recirculating Deep Water Culture (RDWC)\u003cbr data-start=\"2688\" data-end=\"2691\"\u003e• Pot capacity: 20L per plant site\u003cbr data-start=\"2725\" data-end=\"2728\"\u003e• System volume: 75L\u003cbr data-start=\"2748\" data-end=\"2751\"\u003e• Reservoir volume: 120L\u003c\/p\u003e\n\u003cp data-start=\"2779\" data-end=\"2792\"\u003e\u003cstrong data-start=\"2779\" data-end=\"2792\"\u003eFootprint\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2794\" data-end=\"2912\"\u003e• Minimum footprint: 1.1m × 0.7m\u003cbr data-start=\"2826\" data-end=\"2829\"\u003e• Maximum footprint: 1.36m × 0.96m\u003cbr data-start=\"2863\" data-end=\"2866\"\u003e• Recommended plant spacing: 50–60cm centres\u003c\/p\u003e\n\u003cp data-start=\"2914\" data-end=\"2928\"\u003e\u003cstrong data-start=\"2914\" data-end=\"2928\"\u003eWater Pump\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"2930\" data-end=\"3022\"\u003e• Model: JET-STREAM™ SILENT 1.0\u003cbr data-start=\"2961\" data-end=\"2964\"\u003e• Maximum flow rate: 950 L\/hr\u003cbr data-start=\"2993\" data-end=\"2996\"\u003e• Power consumption: 16W\u003c\/p\u003e\n\u003cp data-start=\"3024\" data-end=\"3066\"\u003e\u003cstrong data-start=\"3024\" data-end=\"3066\"\u003eRecommended Air Pump (sold separately)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"3068\" data-end=\"3135\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Model: JET-35\u003cbr data-start=\"3083\" data-end=\"3086\"\u003e• Air output: 35 L\/min\u003cbr data-start=\"3108\" data-end=\"3111\"\u003e• Power consumption: 20W\u003c\/p\u003e","brand":"Hydro Crop Shop","offers":[{"title":"No Tank \/ No Pump","offer_id":52696236032266,"sku":null,"price":385.0,"currency_code":"GBP","in_stock":true},{"title":"No Tank \/ With Pump (Jet Stream 950L PH)","offer_id":52696236065034,"sku":null,"price":421.95,"currency_code":"GBP","in_stock":true},{"title":"120L Tank \/ No Pump","offer_id":52696236097802,"sku":null,"price":500.0,"currency_code":"GBP","in_stock":true},{"title":"120L Tank \/ With Pump (Jet Stream 950L PH)","offer_id":52696236130570,"sku":null,"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\/tanvir-copy","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
