{"product_id":"growlink-link-hub","title":"Growlink LINK Hub","description":"\u003ch2\u003eGrowlink LINKS HUB for Centralized 8-Port Device Control\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe \u003cstrong\u003eGrowlink LINKS HUB\u003c\/strong\u003e powers and communicates with up to eight LINK devices over standard RJ-45 cabling. Each port supplies up to \u003cstrong\u003e1A at 24VDC\u003c\/strong\u003e through the cable itself. Valves, relays, and sensor modules pull both data and power from the same line. The HUB itself runs \u003cstrong\u003e24VDC at 3W\u003c\/strong\u003e from the included AC\/DC supply. Network connection uses Ethernet for primary uplink with Wi-Fi available as a backup channel to Growlink OS. Operating range covers \u003cstrong\u003e50–122°F (10–50°C)\u003c\/strong\u003e and \u003cstrong\u003e0–75% RH non-condensing\u003c\/strong\u003e, suitable for greenhouse and indoor cultivation.\u003c\/p\u003e\n\u003ch2\u003eWiring a Centralized Automation Hub for Multi-Device Grow Operations\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003ePlan the eight ports around device priority: HUB-required modules first (relayLINK and quadLINK), then optional-HUB devices (valveLINK, canopyLINK, lightLINK) that could otherwise run over Wi-Fi. Place the controller centrally to keep cable runs short and reduce voltage drop on the PoC line. The 1A-per-port budget is the constraint worth checking. A quadLINK and a relayLINK draw their own data current, while sensor hubs and valve drivers add their loads. For facilities needing more than eight devices, scale by adding additional HUB units in the same Growlink OS account. Each new HUB appears as a separate communication node in the dashboard. The trade-off is that every HUB needs its own Ethernet port. Plan switch capacity at the network layer before expanding past two or three HUBs per room. This is what the \u003cstrong\u003ecentralized automation hub\u003c\/strong\u003e design buys you — one network drop, one power supply, eight device channels.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 RJ-45 Device Ports with PoC:\u003c\/strong\u003e Each port supplies up to 1A at 24VDC over the same cable that carries device data — fewer power supplies, cleaner wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEthernet + Wi-Fi Network Connectivity:\u003c\/strong\u003e Plug into the local network over Ethernet for primary uplink or fall back to Wi-Fi when running tents or temporary spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowers Every Wired LINK Device:\u003c\/strong\u003e Required for relayLINK and quadLINK, optional for valveLINK and canopyLINK; one HUB anchors the full LINKS deployment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandalone or Multi-HUB Scaling:\u003c\/strong\u003e Run one HUB per room or add additional HUBs to the same Growlink OS account for larger facilities.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Built for greenhouse and indoor agricultural environments with serviceable construction.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #333; color: #fff;\"\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eInput Power\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e24VDC, 1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePower Consumption\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e3W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eDevice Ports\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e8× RJ-45 (PoC up to 1A at 24VDC per port)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eNetwork Uplink\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eEthernet (primary) + Wi-Fi (backup or primary)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e50–122°F (10–50°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eOperating Humidity\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0–75% RH (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eDimensions\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e7.75\" × 7.75\" × 3.75\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCompatibility\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eAll Growlink LINKS modules (relayLINK, quadLINK, valveLINK, canopyLINK, lightLINK, and more)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eIncluded Hardware\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eAC\/DC power supply, 10-foot RJ-45 cable, mounting kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eMade in USA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Growlink","offers":[{"title":"Default Title","offer_id":48240787947734,"sku":"GL-LINK-HUB","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Growlink_Links_Hub_main_image.webp?v=1778542463","url":"https:\/\/growershouse.com\/products\/growlink-link-hub","provider":"GrowersHouse","version":"1.0","type":"link"}
