Does anyone use and outdoor RO unit for greenhouses/bog gardens. I'm interested in purchasing an RO unit for my outdoor/indoor plants. I'm looking for any kind of RO Unit that will attach to my outdoor spicket. Any ideas? I've used tap (90 to 100ppm) on my CPs for a long time with no problem but my collection continues to grow and feel that over time hardwater buildup in my bogs could be a problem.
