I am one VERY happy green thumb girl. I was gifted a RO filter by my awesome husband 💕 I've been wanting one for a loooong time! I can't wait to get rid of (recycle) all my water jugs I used to collect rain water. My rain barrels have been very dry and I have been buying water. I refuse to use nasty tap water. This will really make my "grow life" easier.... It wasn't that expensive. This model was $150, well worth the investment!
