Indoor farming companies like Eden Green Technology are gaining momentum as they aim to produce fresh produce year-round while reducing water and land usage and protecting crops from climate change. However, some rivals are struggling or filing for bankruptcy. Plenty Unlimited is investing $300 million in a new facility, and Kroger is expanding its availability of vertically farmed produce. Critics argue that high energy costs associated with artificial lighting can make profitability difficult for indoor farming. Some experts believe that investing in practical solutions for outdoor farming or climate initiatives might be more beneficial than expanding indoor farming operations. Pest control and scaling up operations are also challenges faced by indoor farms. However, some companies are confident in their approaches, such as relying on natural light or efficient lighting systems. Walmart has invested in Plenty, but skepticism remains about the overall profitability of indoor farming.
