The city I live in has hard water. From the latest report 2008 the average is ‘very hard’ at 160ppm (around 9.3 grains per gallon). There looks to be a lot of calcium and magnesium in the water, and it is treated with chlorine apparently. The average pH of tap water is also 7.9.
I haven’t done an official pH test yet myself, but my tap water has a yellow tint in large quantities. I have a filtered dispenser pitcher for drinking and cooking.
My question- will using my tap water detrimentally affect my Roma and Sweet 100 tomato (or my Spicy Globe basil) plants? Should I use filtered water or just treat the tap water somehow before hand? My thought is that the Ca and Mg would actually benefit my plants, but the alkaline pH worries me (should it?) I planted them in Miracle-Gro potting mix last week and it’s "fertilizer analysis" is 0.21-0.7-0.14
To the plant’s credit- they seem to be doing fine, one is particularly happy and has grown at least half in size (Roma last week 4in, today about 6in!) I’ve pinched off the few flowers that’ve appeared and will continue to do so until the plants are at least 18" They get filtered sun from sunrise and full sun from 10AMish to sunset. (Is that TOO much? it’s at least 10hrs). If it helps, I live in Los Angeles, CA (yup I’m planning on getting a shade for them come July).
Any opinions on the water or anything else is very much appreciated. I’m a worrynut, so sue me :)
