Put your rain barrels to good use with Irrigatia's SOL-K12 watering kit. The easy to use drip irrigation system uses a solar pump to redirect water from rain barrels or other non-pressurized water sources to hanging planters, patio pots or garden plants. Using solar power alone, there is no need for complicated and expensive electrical or pressurized water hookups. The Irrigatia kit self-waters every three hours, providing less water on cloudy days and more when it's sunny and is easily adjusted to pump more or less as needed. Ideal for small watering projects, fertilizer can be added to the water source to feed plants as it simultaneously waters them making the SOL-K12 kit the perfect
garden-sitter when you need to get away for a few days. Available online for $120.
