Thanks for the input guys. I had one of those 5 filter 100$ ones. It was slow as molasses. On a good day it might do a gallon in 45 minutes. Left it out for a winter accidentally and all the lines became brittle and cracked. My own fault, but that has led me to looking for something hopefully a little faster.
I think that Hydro-logic filter looks like a pretty good setup for my purpose. I'm going to do some more research on it and see what the replacement filters go for. I'll also keep looking around and do comparisons. I'll report back with what I wind up deciding on.
Right now I'm using Poland Spring at about 5$ per 5 gallons. not a ton of money but I anticipate these plants using lots of water in the height of flower. Especially int he summer months as I have passive intake/cooling. I'm figuring, conservatively I think, that I'll need a gallon a day at most for each plant. That's 6 gallons a day potential. So If I could get 8-10 gallons in an hour's time I would be pretty happy.
Thanks again.
