My city has some of the best tap water in the nation, ok for plants?

We always rank high on those lists of best tap water. The guy at the hydro shop said to just add some ph down and it's good to go. Someobody else (not related to growing) told me that it's "dead soft".

Also, will the fridge filter help the water at all?

Thanks.

no.......your city still uses chlorine/chloramines

The water is fine for plants.

Your water will most likely be just fine. The casual rule is if it's fine to drink it's fine to feed them with. Mine is rated as extremely hard, comes out of the tap with a ph of over 8, few millilitres of Ph down and it's all good.

Sorry, the microbes aren't THAT sensitive that they are going to fall over dead from the slightest whiff of chlorine.

The only time I treat my water is the month of March when they douche the system with chlorine to clean it out. Other than that, it's chloramine at 3ppm or less. None of the plants or the garden, all organic, show any ill effects. Micro herd is doing fine.

I don't ph it either. Using 100-150 gallons to water everything inside and out precludes that sort of silliness. Between the lime and the micro herd, it's taken care of.

Vitamin C in lemon juice takes care of the chlorine/chloramines. Use it to lower your pH.

When RO water is $ 1.50 for 5 gallons from any grocery store fill station why risk hurting your girls with additives like ph up and down. I guess it depends on your abilities as a grower to monitor your system. Will it kill them, no. Get the right water the first time and you wont need to make many corrections. HAPPY GROWING FRIEND

No risk and no need. Cannabis has done just fine for i don't know, just 1 or two years or so without the invention of RO water and don't just dandy

All one has to do is to look at your past threads.

I'm a sporting man. Please post a pic of something you harvested in all those years before I was born.

First off I am in the commercial water treatment biz, take your hydro store dudes comments with a grain of salt. Always do a water analysis so you know what your baseline is. You would be very suprised at what muni's supply to their customers. The obvious chlorine/chloramine additive and depending on the exact locations of the wells or surface water source the water can have a very high concentration of disolved solids - not necessarily good when watering your girls. I personally use a 55 gallon trash container placed under a gutter downspout - cheap and always available. Tends to be a little acidic due to proximity to steel mills (read acid rain) but pretty close to 6.3 ph with less than 10 ppm disolved solids.

Same here. I use 25-35gal of water every day, and a pH-balanced fertilizer and lime in the medium. Never measure pH. Never found the need. Just pulled a personal best of 4.1oz per square foot (dry) under 1Ks.

Here is my local tap water, never had a problem growing ganja with it, though as the temprture gets very low they inject more chloramines or chlorine into it and it makes my cup of tea taste like shit...... my ater is good for my weed, no so good for a tasty cup of tea lol
