Q.

best water source for seed-starting

Zone Jonesborough, TN | msharrisjr added on May 5, 2019 | Answered

is there any merit to the argument that fluoridated town water should be avoided for seed-starting and seedling transplant purposes, and that no-chemical roof or stream water is preferable?

I have been growing for 30 years and haven't had trouble with city tap water. Most cities have switched from chlorine to chloramine. Check with your water department. I think it is more of an issue with houseplants that are repotted every few years and where chlorine levels can build. Chlorine is highly volatile and "off gasses". Leaving tap water uncovered overnight reduces the chlorine content significantly. Chloramine does not which makes it a safer chemical to use from a safety standpoint. If you are concerned, using a filter pitcher will remove chlorine.
