Water?

I know most of you all use distilled water and I also do. I wonder if you could use lake water from a fresh water lake. Or is there a way to get the colrie out of tap water. The reason I ask about lake water is that I am at the lake 4 to 5 times a week due to I was a pro wakeboarder and still teach and give lessons. Any ideas would be helpful. My wife is tired of going to the store for water:)

If you just let the chlorine evaporate from the tap water by letting it sit out for at least a day I think you'd be fine... I went so far as to collect rain water however the other day for my seedling.

Is there a way to test for chlorine?

you can get a ph test I'm sure, just like a strip or maybe there are digital ones to.

I have a ph tester but I am not sure that will tell me if chlorine is in that water and it will harm the plants.

Well you want a P.H of about 7.0 isn't it? The neutral level.

just did a little test right out of the tap yikes came with a 8.5 I am going to let water from the tap sit a few days and then test it.

I use tap water. All plants seam to grow just fine o.0

i dont think the chlorine is a problem with tap water just the high ph

All right party people, here's the deal:

You can't determine presence/absence of chlorine by testing pH.

MArijuana likes a pH that is slightly acid, approximately 6.3 to 6.8.

Did you know that distilled water, when allowed to air-equilibrate, actually has a weakly-acid pH as a result of atmospheric CO2 going into solution and going into equilibrium with Carbonic acid?

Lake and rain water will 99% of the time be slightly acid as well.

LAke water does contain low levels of dissolved nutrients; the amount varies depending on the region, the watershed, the substrate, biological activity, time of year, etc.

If you use tap water and really worry about chlorine, you can let it sit with an airstone in it overnight to air-equilibrate. At room temperature, pure Chlorine exists as a gas. In natural lake water, it will be found as an part of a molecular substance such as sodium chloride (NaCl) which is table salt, or CaCl, which is road salt, or any of an innumerable array of substances.

The amount of chlorine left in tap water after leaving it out all night should NOT harm you plants.

If you want to test for chlorine, pool supply stores should have chlorine test kits in stock, but the sensitivity is low because of the very high levels of Cl expected in swimming pools.
