Five pack of olla watering stakes with an adapter so it can accept 1/4 inch irrigation tubing for efficient automated watering. Just connect it to a bucket to feed them with gravity. It is not reccomended to hook up to mains water, as the pressure may break it. May arive wet from testing for leaks. Picture shows my tomato plants i pots in the 95 degree weather here in Florida. Despite being in pots they are happy and healthy.
