Sure thing Reg. You may have seen the machines around in the city where you can fill up your own water jugs. They use reverse osmosis to clean the water. The bottled drinking water that you might buy has also been cleaned with reverse osmosis, but usually they then add minerals back into the water because the minerals make the water taste good. The thing is, the minerals they add back are not necessarily the ones or the right ratio you would want for your plants. If you see one of those machines around, it is usually only 25 cents a gallon.
