collecting, storing, and using rainwater for watering gardens
I know it's been done, but I have some questions and concerns. I want to set up a rainwater collection to use mainly to water my potted outdoor plants and perhaps flower and vegetable gardens around the yard. Does anyone sell these collection systems? I suppose I could just use a 55 gallon drum and stick it under the downspout too.
Is there a way to hook a hose up to the tank and let the weight of the water itself act as pressure to make the hose run?? Is the asphalt in the roof shingles an issue in using it on plants??
