Pick of the day

The Hardest Harvest, 9.35pm, RTÉ One

An Irish farmer, forester and fisherman travel to the harshest of environments in some of the world’s poorest countries to live off the land and sea using nothing but bare hands and basic tools.

First up, Cork dairy farmer Paula, Waterford forester Jamie, and Dublin skipper ‘Big’ John each leave behind family and friends to spend two and a half weeks living a hand-to-mouth existence in remote rural Africa.

Hunting and herding with spears, logging by hand and fishing an open ocean in the flimsiest of vessels, they push themselves to the edge to understand the struggles their African hosts face.

Ending Tonight

Grow, Cook, Eat, 7.30pm, RTÉ One

The final programme in this 'grow your own' series is all about peas, the botanical fruit that's rarely sold fresh, and generally comes frozen.

Michael Kelly heads to Dublin and visits Airfield House and Gardens, Karen O'Donohoe is back in Cork looking at another great community growing project, and chef Jessica Murphy prepares Roasted Pea Soup and Pea Dip in the Grow Cook Eat kitchen.

House: Seasons 1-8, Sky Box Sets & NOW TV

Here are all 177 episodes of the Emmy Award-winning medical show and its iconic, idiosyncratic lead character, played by Hugh Laurie.

Although it's basically a 'case of the week' drama, it really stands out due the strength of the main characters, particularly the eponymous Dr Gregory House, superbly played by Hugh Laurie, an unconventional and misanthropic medical genius.

Like most shows, it wanes a little near the end of its (eight season) run, but the first five or so are excellent.

Don't Miss

The Americans, 12.00am, RTÉ 2

I'll keep plugging this riveting spy/family drama show because it's easily one of the best shows on the box and it generates so little attention it borders on criminal neglect.

This week:  secret brings Elizabeth and Paige together, while in Moscow, Oleg's secrets put him under KGB suspicion – which is never a good thing.

And there's a new twist in the Morozov operation which creates an opportunity that changes everything.
