Revers Osmosis System Advice Needed

[Becca]

I couldn't remember where I should post this thread...so here it goes. I am looking into a reverse osmosis water system. I can rent one from Culligan for $34.00 a month and it will hold up to 3 gallons and I couldn't remember if they told me I could draw 10 gallons or 30 gallons a day on it, but either way I would have to have something to store the additional water in, because I use the s/h culture I go through probably in between 5 to 10 gallons of water on watering day. To refill the tank I would have to wait an hour, so I would start drawing from the tank the night before since waiting for water to filter is what I am trying to avoid since I am currently using a Britta water pitcher to filter my water while watering the 'chids. I wonder if a RO system will be as big of a pain and as slow as the Britta? I have roughly 30 plants and it is taking me about 2 to 3 hours to water my plants because I am waiting on the water to filter. I under stand the RO system will remove more then the Britta does....but would it really save me time and be worth it? Any users have any input? TIA!
