Thanks, optique, for the feedback! I figured as clear as it is that it should be fine for a while but didn't know for sure. I rinsed some peat moss this afternoon with some of the water in my 32-gallon "strategic reserve"
garbage can (21-22ppm). I'm going to rinse a batch of perlite tomorrow. When I'm finished I'm going to top the garbage can back off with this water, which should lower the bulk water's TDS measurement a bit. The rest will go in the humble gallon milk jugs.
The last rain we got was a really nice, *clean* rain, that fell onto a recently rain-rinsed roof.
It looks like we may get another good rain (1+" possible) tomorrow afternoon/night so I need to get things done and set up the pots and cooler!
With rainwater being *free* I'm a sucker for collecting it...much more than I need for the number of plants that I have. BUT, late this past summer we hit a dry spell and I began to approach needing to tap into the strategic supply. I max out at around 60 gallons of stored water...buckets, jugs, and garbage can. I need to start thinking about streamlining my setup a bit.
Anyhow, I was wondering about the leaves and acorns in the water. Thanks for quelling my concern!
