I'd been thinking about buying some self-watering troughs for my very sunny front garden for ages. I wanted a contemporary look but an effective watering system as I am only here during the working week. I finally decided to buy from Lechuza - not cheap but well-designed. Service was excellent and delivery prompt. I bought 2 Trio 30 troughs, with 3 individual compartments in each. Working out the assembly of the water indicator for the first compartment took me a little time to puzzle through - following the instructions for the Cubico inside the irrigation box proved the right choice. The others took moments to put together - that's learning! Easy to plant up and good guidance on getting the plants established. They look pretty good though I say it myself.
