Just picked up a 5 pack of these for just under $40 delivered. Looks like a great way to deliver water slowly to the root system of plants.

I'm about to trial a couple on some fruit trees I'm planting and then, if they work OK, planning to use them for some bush grows this summer. [I will have to cart in water as don't have the luxury of an available water source in our bush!].

Not sure that 10L would last for 6 weeks during the hottest part of our summer, but it should be pretty efficient when delivering the moisture below ground. And will hopefully allow me the luxury of leaving plants unattended for a week or two.
