I have thought about buying a RO unit, but still have not.
I collect rain water when it rains. Around 35 gallons of it. If its dry I go up to the store about 5 minutes away with my gallon jugs and fill them at a RO unit that cost 25 cents per gallon.
The summer is the worst for me with my outside plants. I do not grow my plants in trays and they need watered every other day. I end up using around 10 gallons a week.
I guess my N. rajah likes me.
The soil mix I use is equal parts perlite, peat moss, and dry LFS. This is pretty much my standard mix for most of the CP's I grow. I top dress my neps with live LFS moss when the plants are bigger. I also do this with some other CP's as well
My neps that grow inside year round get watered twice a week, as for all my inside plants.
