{"product_id":"treegers-gl-led-1","title":"Treegers GL LED","description":"\u003cp\u003eThe Treegers GL LED is a full-spectrum grow light built from detachable LED bars that click magnetically into the frame. The driver is integrated into the fixture, so there is no separate ballast to mount. Its Full-Spectrum Fusion spectrum is balanced for full-cycle growing, and Treegers also position it as an optimal choice for propagation, clones, mothers and vegetative growth, so one fixture can stay in place from the first cuttings through to flowering. The GL is one light built in two sizes: the GL300W runs four bars and the GL420W runs six, spreading the same spectrum and efficacy over a larger footprint.\u003c\/p\u003e\u003cp\u003eThe multi-linear layout spaces the bars across the frame, and each bar spreads its light at a 120 degree angle, so the canopy is lit from several points rather than from one central source. That overlap helps even out intensity between the middle of the canopy and its edges. Cooling is entirely passive: heat leaves through the fixture itself, with no fans to clog, clean or fail. Treegers quote a diode efficacy of up to 4.2 μmol\/J and a whole-fixture efficacy of 2.8 μmol\/J. A gap between the two is normal, because the fixture figure includes what is lost converting mains power in the driver. That makes it the more honest guide to how much light each watt actually delivers. On the GL420W, Full-Spectrum Fusion is built from 4000K and 5000K white diodes with 660 nm deep red, a wavelength close to the absorption peak of chlorophyll that adds efficient red to a broad white base.\u003c\/p\u003e\u003cp\u003eTreegers rate the GL420W for a larger area than the GL300W, while the PPFD maps measured for each model show the four-bar GL300W spreading its light more evenly across its own recommended area. Both models are dimmable through the Treegers Precise T Dimmer, which is not part of the box contents. Starting seedlings and fresh cuttings at a low dimmer setting, then raising the output as the plants establish, keeps young growth from being pushed harder than it can use. It also lets the same light carry the crop through to flowering without being swapped out.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/67AvKd-XBzU\" title=\"Treegers GL300W \u0026amp; GL420W LED Grow Light Fixtures\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Treegers","offers":[{"title":"GL300W","offer_id":67546258571422,"sku":"9309001188030","price":530.99,"currency_code":"AUD","in_stock":true},{"title":"GL420W","offer_id":67546258604190,"sku":"9309001188047","price":665.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/Treegers_GL300W.png?v=1760420805","url":"https:\/\/www.hydrooasis.com.au\/products\/treegers-gl-led-1","provider":"Hydro Oasis","version":"1.0","type":"link"}
