The kit branches one canopyLINK HUB port across multiple ClimaLINK or TerraLINK sensors. The 4-pin M8 connectors at every junction stay sealed against grow-room humidity and the daily dust that kills generic patch cables. The T-connector lets one HUB port feed two sensor branches at the same time. The end cap closes off any unused branch leg to keep the bus terminated cleanly. Plug-and-play mating means no firmware setup — auto-addressing on the canopyLINK side picks up each connected sensor on the next sweep.\u003c\/p\u003e\n\u003ch2\u003eSplitting Sensor Branches with an M8 Sensor Extension Kit\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eRun two sensors per HUB port instead of one — climate on one branch, substrate on the other. This frees up the remaining canopyLINK ports for additional zones. Place the T-connector near the canopy so each branch can route to its sensor location without strain. Daisy-chaining beyond a single split risks signal weakening on long cable runs. For more than two sensors per branch, drop in an additional HUB or canopyLINK module rather than stacking extra T-connectors. The end cap matters more than it looks: an open branch leg can collect moisture and corrode the contacts over a flowering cycle. Cap the unused side at install and the assembly stays sealed for the life of the run. The trade-off is that every M8 mating point is one more thing to inspect. Pull the connectors at room turnover and check for green oxidation before re-mating — early corrosion is the first sign a junction is leaking signal.\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\u003eBundled 5m Cable + T-Connector + End Cap:\u003c\/strong\u003e Branch one canopyLINK HUB port between two M8 sensors without buying separate fittings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed M8 4-Pin Connectors:\u003c\/strong\u003e All junctions stay sealed against humidity and dust for the life of a flowering cycle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-Play with Auto-Addressing:\u003c\/strong\u003e Plug in, mate the connectors, and the canopyLINK sees each sensor automatically.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull ClimaLINK \u0026amp; TerraLINK Compatibility:\u003c\/strong\u003e Climate, substrate, CO2, light, moisture — any Growlink M8 sensor works on the bus.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCultivation-Grade Construction:\u003c\/strong\u003e Shielded cable and end-cap termination keep signal clean in grow-room environments.\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;\"\u003eKit Contents\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e5m M8 extension cable, M8 T-connector, M8 end cap\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCable Length\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e5 m (~16.4 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eConnector Type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eM8 4-pin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eSensor Compatibility\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eClimaLINK, TerraLINK, and other Growlink M8 sensors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eHub Compatibility\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003ecanopyLINK Sensor HUB M8 ports\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eSingle HUB port splits to two sensor branches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eConstruction\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eShielded cable, sealed connectors, cultivation-grade jacket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePlug-and-play (hand-tightened mating, no tools)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eSensor Types Supported\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eClimate (temp, RH, VPD), substrate (VWC, EC, temp), CO2, light\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Growlink","offers":[{"title":"Default Title","offer_id":48240874881238,"sku":"GLM8-EXT-KIT","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Growlink_M8_Extension_Cable_Kit_main_image_with_T_connector.webp?v=1778545649","url":"https:\/\/growershouse.com\/products\/growlink-m8-extension-cable-kit-5m","provider":"GrowersHouse","version":"1.0","type":"link"}
