I have a supply of well water to my greenhouse. This water is not suitable for long-term use on plants because of the hardness. This water eventually leaves calcium deposits that are unsightly and harmful to the plants.
For some time, I used an RO system with a booster pump. The system charged a large (deep well) bladder tank and stored about 15-18 gallons of water total. This type of system has its flaws, namely that the booster pump wears out (twice in 3 years) due to the high back pressure on the system and the fact that it is running all the time. The system goes through lots of membranes, which are expensive. It doesn't hold much water. And finally it doesn't take advantage of free, clean water in the form of rain. So I reengineered the entire system. Thanks to tigerlily123 for the original inspiration, and thanks to nautical99 for sharing the details of his system with me.
First I attached gutters to both sides of the greenhouse.
