My Life: Home Grown Boys 4.30pm, BBC1 This charming documentary profiles a group of inner-city boys who spend their summer holidays growing and selling veg from a site in London's King's Cross. Land is provided by the council and start-up funds are obtained from a local charity, but these kids otherwise have autonomy over their project, selecting seeds and offering their wares to some high-profile businesses, including Eurostar and the Guardian. With a window of six weeks in which to grow and sell their product, the young entrepreneurs are under significant pressure, but the boys turn a significant profit. Gwilym Mumford Bees, Butterflies And Blooms 8pm, BBC2 In this final episode, Sarah Raven looks at how our urban jungles can benefit from flowers and bees, and vice versa, fostering a sense of community spirit all round. In Birmingham, she inspires the city council to sow flower meadows and plant displays; in London, she follows progress at the Olympic Village, where the landfill is being transformed into pollen-rich meadows, and asks if this could be a blueprint for the way we plant our cities in future. Ali Catterall Thames Treasure Hunters 9pm, National Geographic Modern-day mudlarks trawl through the sludge of London's famous river in search of stuff they can sell. It's a centuries-old tradition, but contemporary dredgers must run the gamut of pollution and lord knows what else lurking deep in the oomska. And their significant finds more often end up in museums than paying for someone's ale. They set to work with metal detectors (cheating), and there are experts from the Museum Of London on hand to identify and date the loot. Fully fascinating. Julia Raeside Storyville: Deadline – The New York Times 10pm, BBC2 Ah, newspapers. What is to be done with them? Facing the dual threat of new media and declining ad revenues, they have their backs against the wall and, in the US at least, many have gone out of business. The New York Times soldiers on and, as this peek inside the great institution shows, the staff are as dumbfounded as anyone, though at times, impressively optimistic about the paper's survival. First shown on BBC4. Martin Skegg American Guns 10pm, Discovery A series following Colorado-based firearm fetishists the Wyatt family, who run Gunsmoke Guns, one of America's most prestigious gun facilities. The Wyatts deal in bespoke weaponry, and proudly boast of their ability to craft a handgun from scratch out of a chunk of metal, something of a throwback in this era of mass production. In this opening episode, patriarch Rich and his team of master craftsmen attempt to recreate the "knuckle duster", a set of brass knuckles concealing a small revolver, a weapon that had its heyday of popularity in the 19th century. GM Lowdown 10.30pm, BBC4 Flatmates Alex and Bob (think two Simon Peggs‚ one a little bit Peggier than the other), allow sex symbol Oliver Barry – a certain Mr R Crowe, basically – to crash at their pad in what is essentially Australian television's riotous answer to Drop The Dead Donkey. Barry wastes no time in noisily getting off with Alex's love interest, Rita (Alex: "You're not supposed to go off and sleep with the sexiest man alive!" Rita: "How am I supposed to know that, I can't read your mind!"), before a satisfying comeuppance is achieved. AJC
