People are growing food on rooftops, balconies, and backyards \u2013 but how about in abandoned warehouses or basements?<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Professor Xiusheng (Harrison) Yang in the <a href=\"https:\/\/cahnr.uconn.edu\">College of Agriculture, Health and Natural Resources<\/a> has invented a technology, GREENBOX, that can grow high-quality food in existing indoor urban spaces.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang, a professor in the <a href=\"https:\/\/nre.uconn.edu\">Department of Natural Resources<\/a>, first had the idea to develop GREENBOX five years ago after observing the unmet need to grow food locally in urban environments.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">\u201cThere\u2019s a need to produce food locally in urban areas where people need it the most,\u201d Yang says.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Current GREENBOX models are about the size of a standard commercial pallet \u2013 48 inches by 40 inches. Yang says that the height can be variable, depending on the crops, reaching upwards of 84 inches high.<\/p>\r\n\r\n\r\n\r\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\r\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"193711\" class=\"alignnone wp-image-193711 img-responsive lazyload\" data-src=\"https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9104-002-rotated.jpg\" alt=\"Lettuce in a grow facility\" width=\"756\" height=\"1008\" data-srcset=\"https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9104-002-rotated.jpg 756w, https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9104-002-225x300.jpg 225w, https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9104-002-315x420.jpg 315w, https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9104-002-499x665.jpg 499w\" data-sizes=\"(max-width: 756px) 100vw, 756px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 756px; --smush-placeholder-aspect-ratio: 756\/1008;\" \/>\r\n<figcaption class=\"wp-element-caption\">Lettuce being grown in GREENBOX (Contributed photo)<\/figcaption>\r\n<\/figure>\r\n\r\n\r\n\r\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"193710\" class=\"alignnone wp-image-193710 img-responsive lazyload\" data-src=\"https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9515-002-rotated.jpg\" alt=\"Smiling man with lettuce in greenhouse\" width=\"756\" height=\"1008\" data-srcset=\"https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9515-002-rotated.jpg 756w, https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9515-002-225x300.jpg 225w, https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9515-002-315x420.jpg 315w, https:\/\/today.uconn.edu\/wp-content\/uploads\/2022\/12\/IMG_9515-002-499x665.jpg 499w\" data-sizes=\"(max-width: 756px) 100vw, 756px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 756px; --smush-placeholder-aspect-ratio: 756\/1008;\" \/>\r\n<figcaption class=\"wp-element-caption\">Former graduate student Ankit Singh poses with lettuce grown with GREENBOX (Contributed photo)<\/figcaption>\r\n<\/figure>\r\n<\/figure>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">The insulated boxes contain programmable LED lights that Yang and his team can adjust to fit the light needs of a specific crop and a hydroponic growing system. Hydroponic systems grow plants without soil, using water-based mineral nutrient solutions instead.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang\u2019s team can control the temperature, humidity, and carbon dioxide levels in the GREENBOX and monitor the plants\u2019 progress remotely using the video systems with which each GREENBOX unit is equipped.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">\u201cIt\u2019s a true plant factory,\u201d Yang says.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang and his students conducted a feasibility study where they demonstrated that they could successfully grow 48 heads of lettuce (24 heads each in two units) in 30 days, through every season in Storrs, Connecticut. They published their results in <a href=\"https:\/\/www.scirp.org\/journal\/paperinformation.aspx?paperid=113993\">Agricultural Sciences<\/a> in 2021.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang emphasizes that this feasibility study was a proof-of-concept and GREENBOX\u2019s technology can easily be scaled up.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">\u201cIt creates a lot of flexibility for food production so it can meet the needs of different seasons and different varieties with very limited space,\u201d Yang says.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">GREENBOX offers many advantages over traditional greenhouses. Because they are designed to be set up in unused urban structures, GREENBOX units greatly reduce transportation costs, both in terms of money and carbon emissions.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Further, GREENBOX does not face many of the challenges traditional farming does, such as weather-related disruptions to the growing season or pests. The latter also means there is no need to apply pesticides to GREENBOX crops.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">GREENBOX also uses less energy and water than traditional greenhouses, which Yang outlined in another publication for the <a href=\"https:\/\/elibrary.asabe.org\/abstract.asp?JID=5&amp;AID=52508&amp;CID=virt2021&amp;T=1\">American Society of Agricultural and Biological Engineers.<\/a><\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang also published a <a href=\"https:\/\/elibrary.asabe.org\/abstract.asp?JID=5&amp;AID=53509\">financial feasibility study<\/a> in 2022 showing that GREENBOX would be profitable in major cities across the U.S. Yang\u2019s study included Dallas, Los Angeles, Miami, and New York City. He found that GREENBOX was most profitable in cities, like Dallas, where the cost of renting space and labor were lower, but it would still be profitable in locations like New York City where these costs are some of the highest in the nation.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang says the crops best suited for growing in GREENBOX are leafy greens, like lettuce, as well as cannabis, since these plants have low maintenance needs and do not need soil to grow, like potatoes or carrots would.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">\u201cWe see a lot of potential for the technology in urban applications,\u201d Yang says.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Yang is now working with his students to analyze how to optimize the heating and ventilation systems by testing alternative materials and designs.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">GREENBOX\u2019s development has been supported by funding from the USDA Hatch Act.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><em>Follow <\/em><a href=\"https:\/\/linktr.ee\/uconncahnr_social\"><em>UConn CAHNR<\/em><\/a><em> on social media<\/em><\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>GREENBOX can grow high-quality food in existing indoor urban spaces and meet the need for local, sustainable food<\/p>\n","protected":false},"author":127,"featured_media":193707,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_crdt_document":"","wds_primary_category":0,"wds_primary_series":0,"wds_primary_attribution":0,"footnotes":""},"categories":[2224,2300,2076,2364,2235,2306,2227],"tags":[],"magazine-issues":[],"coauthors":[2140],"class_list":["post-193706","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cahnr","category-natural-resources-environment","category-research","category-technology-commercialization","category-today-homepage","category-uconn-voices","category-uconn-edu-homepage"],"pp_statuses_selecting_workflow":false,"pp_workflow_action":"current","pp_status_selection":"publish","acf":[],"publishpress_future_action":{"enabled":false,"date":"2026-05-08 11:08:27","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/193706","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/users\/127"}],"replies":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/comments?post=193706"}],"version-history":[{"count":5,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/193706\/revisions"}],"predecessor-version":[{"id":193715,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/posts\/193706\/revisions\/193715"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media\/193707"}],"wp:attachment":[{"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/media?parent=193706"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/categories?post=193706"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/tags?post=193706"},{"taxonomy":"magazine-issue","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/magazine-issues?post=193706"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/today.uconn.edu\/wp-rest\/wp\/v2\/coauthors?post=193706"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
