Chlorine - How long to evaporate.

I strongly recommend everyone access the report on their water. I say so on RIU regularly. Available online for most water utilities. Excellent information including levels of calcium and magnesium. Then you can tell if you need to supplement.

I have learned that Ca and Mg from groundwater is not available to plants. Private well water can be many times more contaminated than municipal supplies. Rainwater is my preference and livewell water is awesome. I have even hauled water from the local lake.

Check online for your local municipal water report. If you have your own well, get it tested regularly as conditions change. Agriculture, mining and manufacturing can all have devastating impacts on your water. This impacts your own health and the facts are readily available.

Look under a leaky faucet outside. Even in the desert it's a jungle in the spot.

Thanks for your replies man! Looking good so far, I just had my anesthesia seed sprout today so I am having a great Friday! Hope you all do the same.

"Calcium Source - Water
All water sources supply some calcium. As a general rule, water coming from deep wells or most non-coastal regions of North America has sufficient calcium for normal crop growth, while water from a shallow well, coastal region, rain, lake, river or pond generally has insufficient calcium levels. Regardless, it is best to have your water tested to verify if your water is supplying sufficient calcium. If the calcium level in your water is 40-60 ppm or more, then there is little need to use a fertilizer that provides calcium."

Plants use calcium in tap water just fine.

Adding a cap of hydrogen Peroxide reduces chlorine in water almost immediately. Im not sure what the other side of the reaction contributes but just sharing what I have found. Again, no real need to do such a thing.
