White Full Spectrum or Purple Grow Lights?<\/h3>\r\nPurple (red + blue) lights are efficient but unpleasant to work under and make it hard to spot pests or nutrient problems. White full spectrum lights resemble sunlight, suit every growth stage and show plants in their true colour, so they can be used in homes, offices and shops. All Alton Ray grow lights are full spectrum.\r\n

    FAQ<\/h3>\r\nWhat is the best grow light for an apartment?<\/strong>\r\nThe 18 W I-Gol LI11 or LI12 linear light: white light, low consumption and easy shelf or under-cabinet mounting.\r\n\r\nCan a normal LED bulb grow plants?<\/strong>\r\nRegular lamps are designed for human vision and deliver little useful photon flux. Real growth needs a full spectrum grow light with a specified PPF.\r\n\r\nWhat warranty do the grow lights have?<\/strong>\r\nAll Alton Ray grow lights carry a 3-year factory warranty.","link":"https:\/\/altonray.com\/en\/product-category\/industrial-outdoor-lighting\/horticulture-grow-lights\/","name":"Horticulture Grow Lights","slug":"horticulture-grow-lights","taxonomy":"product_cat","parent":236,"meta":[],"menu_order":0,"_links":{"self":[{"href":"https:\/\/altonray.com\/en\/wp-json\/wp\/v2\/product_cat\/710","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/altonray.com\/en\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/altonray.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"up":[{"embeddable":true,"href":"https:\/\/altonray.com\/en\/wp-json\/wp\/v2\/product_cat\/236"}],"wp:post_type":[{"href":"https:\/\/altonray.com\/en\/wp-json\/wp\/v2\/product?product_cat=710"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
