max FACTS How the Dutch Innovated Greenhouse Tomato Growing Arguably the most popular greenhouse-growing product, tomatoes and greenhouse practises of today owe a big nod to the Dutch, going back to the mid 1990s. The Dutch pioneered indoor tomato-growing techniques that led to varieties that travel well and are extremely flavorful. Growers in the Netherlands pioneered the pelleting system that coats seeds in a protective layer, making it easier for mechanical seed dispersal. Additionally, methods of priming (triggering then stopping the germination process) tomato seeds came from the Dutch, who were among the first greenhouse growers to incorporate geothermal energy to save costs. Horticultural tech companies such as Priva developed automated, climate-control, and water-dosing systems that synchronize variables such as air vents, CO 2  dosage, heating, cooling, and ventilation. Interestingly, nearly 80 per cent of the world’s tomato seeds come from the Netherlands. — qz.com Avocado Seeds Show Anti-Inflammatory Properties Penn State researchers have identified an extract from avocado seeds that exhibits anti-inflammatory ability. The discovery represents a potential source for new anti-inflammatory compounds that might be developed as a functional food ingredient or use in pharmaceuticals. “The next step, before we can draw further conclusions about the anti-inflammatory activity of this avocado seed extract, will be to design animal model studies,” says Joshua Lambert, co-director of Penn State’s Center for Plant and Mushroom Foods for Health. “For example, we can look at a mouse model of ulcerative colitis where we formulate the avocado seed extract into the mice diet and look at whether it is able to reduce inflammation.” Lambert believes the study lays the groundwork for more research because it provides evidence there are bioactive compounds in avocado seeds that have anti-inflammatory activity. “The level of activity that we see from the extract is very good,” says Lambert. — sciencedaily.com Record-Holding Watermelon Equivalent of Two Beer Kegs With summer right around the corner, plenty of people will be enjoying watermelon under clear blue sunny skies. Chances are, when you head to the market, you won’t see a watermelon as big as that grown by Chris Kent. Kent, who is from Sevierville, TN., holds the record for producing the world’s largest watermelon which weighed in at a hefty 350.5 pounds in Oct. 2013. According to the Watermelon Board, the average watermelon weights 20 pounds, so Kent’s giant equalled 17.5 melons. Kent grew the massive melon from seeds he bred himself and cultivated his melon outdoors, but watermelon can be grown indoors and will do well in just about any hydroponic system as long as there’s room to support the big vines. Perlite makes a good watermelon-growing medium, however, growers may prefer something heavier, like clay pellets, pea gravel, or silica stones. — Maximum Yield Staff 22 Maximum Yield
