I think the armour would be a bit OTT to be honest - I plan to run the cable
alongside the irrigation pipes
so http://www.homestead.co.uk/tcjf5005pb.htm would probably be ok!

It'll depend on the length you need and the voltage drop you are
prepared to accept but even the 1/0.50mm stuff should be OK for 50W
