If you aren't getting any deficiencies then I wouldn't worry about it. It costs about $18 a quart where I'm from. Not terrible, but not cheap either. There are a few brands of it. You could order it off of the internet.

LOL! I wish it were that simple. I don't think there is such a thing as "best water". The best water IMO has a very low ppm, and is well aerated. Bottled water is almost always excellent for growing our favorite plant. It typically has a good pH and has some trace minerals in it like calcium and magnesium. I personally use r/o water from one of the grocery store machines. It's much cheaper than bottled or distilled ($.25 per gallon) and it comes out at like 10-15 ppm with a pH around 6.8. I like it because the plants basically get only what I give them. I also like it because my tapwater is utter crap! 600ppm most of the year and not suitable for drinking, let alone growing.
In summary, the best water for growing is whatever works best for your situation. Happy growing.

No problem. Always glad to help.Thanks for the insight! Sure helped me alot!
great info i have been having problems with ? progressively getting worse through flowering. lowest fan leaves brown at the edges and keep browning until fall off. this works its way up the plant but only on fan leaves. i just had my well water tested and ph7.4, hardness 5gpg, iron 0.8-1.0ppm, tds 186ppm, i am using biobizz soil and nutrients which is supposed to lower the ph. i just got a R O and was wondering if this should solve all my water/ nutrient issues? THANKS FOR ANY HELP

186 ppm isn't terrible and pH is easily adjusted but is your water softened? The r/o filter is definitely worth a shot. Just make sure you get some cal-mag or some sort of calcium and magnesium supplement.

Hey Doc thanks for the great thread.
I have hard water. Currently running between 350/400 ppm @ 7.1/7.5 ph. I have been adjusting the ph to 6.0/6.5. I am currently using powder fertilizer that a local here makes Veg is at 20-6-16 and Bloom 9-21-12. I also add a B vitamin supplement. I use the B vitamin with both the Veg and Bloom nutes and my solution is running at 1500/1800 ppm depending on water levels in the solution box. Now 1500/1800 is pretty middle of the road for my culinary herbs and they do fantastic without any issues. Cannabis is also fine during the Veg stage. This is although my first go round using 5 gallon bucket for flower. I had always let mother nature do it before.
I have used this system before for melons and tomatoes and never had any issues with salts I guess this could be due to rapid water uptake during fruiting. I have not ever used distilled or R/O water for the NFT hydro unit. What should TDS be running for bucket system with cannabis?

I'm not a hydro guy but the little I know about hydro it's going to depend on what the strain likes and how big your plants (what stage they are in) are. It's my understanding that r/o or distilled water is even more important for hydro growers. By using purer water you are able to give the plants exactly what they need and there is no garbage in the water that will build up in your medium or interfere with nutrient uptake. Hope this helps, but you should probably check in the hydro forum for an answer to you TDS question. I don't want to give you incorrect information.

Boiling will evaporate Chlorine and kill bacteria. It also reduces hardness a little bit.
Thank you!

Cl2 dissipates in the presence of Free Oxygen and Sunlight. That is why you have to keep adding Cl2 to your pool. What comes out of your tap should be 2 ppm at most after break point and residual. I worked at a water treatment plant I know this shit. Anyway set it outside in the sunlight and the Cl2 will go away in 24 hours. I use city water straight in my misters in the greenhouse and my Girls are Great. The early leaf of while knock you on your ass. Don't be so fucking intense. Remember what this all about. If your city puts fluoride in the water you will have Girls with great teeth at most.

Chlorine
Discovered in 1774 by Carl Wilhelm Scheele, who mistakenly thought it contained oxygen. Chlorine was given its name in 1810 by Humphry Davy, who insisted that it was in fact an element.
The pure chemical element has the physical form of a diatomic green gas. The name chlorine is derived from chloros, meaning green, referring to the color of the gas. Chlorine gas is two and one half times as heavy as air, has an intensely disagreeable suffocating odor, and is exceedingly poisonous. In its liquid and solid form it is a powerful oxidizing, bleaching, and disinfecting agent.
This element is a part of the halogen series forming salts. It is extracted from chlorides through oxidation and electrolysis. Chlorine gas is greenish-yellow and combines readily with nearly all other elements.
Applications
Chlorine is an important chemical in water purification, in disinfectants, in bleach and in mustard gas.
This element is a part of the halogen series forming salts. It is extracted from chlorides through oxidation and electrolysis. Chlorine gas is greenish-yellow and combines readily with nearly all other elements.
Applications
Chlorine is an important chemical in water purification, in disinfectants, in bleach and in mustard gas.
Chlorine is also used widely in the manufacture of many products and items directly or indirectly, i.e. in paper product production, antiseptic, dyestuffs, food, insecticides, paints, petroleum products, plastics, medicines, textiles, solvents, and many other consumer products.
It is used to kill bacteria and other microbes from drinking water supplies.
Chlorine is involved in beaching wood pulp for paper making, bleach is also used industrially to remove ink from recycle paper.
Chlorine often imparts many desired properties in an organic compound when it is substituted for hydrogen (synthetic rubber), so it is widely use in organic chemistry, in the production of chlorates, chloroform, carbon tetrachloride, and in the bromine extraction.
Chlorine in the environment
In nature it is only found combined with other elements chiefly sodium in the form of common salt (NaCl), but also in carnallite, and sylvite. Chlorides make up much of the salt dissolved in the earth's oceans: about 1.9 % of the mass of seawater is chloride ions.
The amount of chloride in soils varies according to the distance from the sea. The average in top soils is about 10 ppm. Plants contain various amount of chlorine; it is an essential microutrient for higher plants where is concentrates in the chloroplasts. Growth suffers if the amount of chloride in the soil fall below 2 ppm, but it rarely happens. The upper limit of tolerance varies according to the crop.

Health effects of chlorine
Chlorine is a highly reactive gas. It is a naturally occurring element. The largest users of chlorine are companies that make ethylene dichloride and other chlorinated solvents, polyvinyl chloride (PVC) resins, chlorofluorocarbons, and propylene oxide. Paper companies use chlorine to bleach paper. Water and wastewater treatment plants use chlorine to reduce water levels of microrganisms that can spread disease to humans (disinfection).
Exposure to chlorine can occur in the workplace or in the environment following releases to air, water, or land. People who use laundry bleach and swimming pool chemicals containing chlorine products are usually not exposed to chlorine itself. Chlorine is generally found only in industrial settings.
Chlorine enters the body breathed in with contaminated air or when consumed with contaminated food or water. It does not remain in the body, due to its reactivity.
Effects of chlorine on human health depend on how the amount of chlorine that is present, and the length and frequency of exposure. Effects also depend on the health of a person or condition of the environment when exposure occurs.
Breathing small amounts of chlorine for short periods of time adversely affects the human respiratory system. Effects differ from coughing and chest pain, to water retention in the lungs. Chlorine irritates the skin, the eyes, and the respiratory system. These effects are not likely to occur at levels of chlorine that are normally found in the environment.
Human health effects associated with breathing or otherwise consuming small amounts of chlorine over long periods of time are not known. Some studies show that workers develop adverse effects from repeat inhalation exposure to chlorine, but others will not.
Environmental effects of chlorine
Chlorine dissolves when mixed with water. It can also escape from water and enter air under certain conditions. Most direct releases of chlorine to the environment are to air and to surface water.
Once in air or in water, chlorine reacts with other chemicals. It combines with inorganic material in water to form chloride salts, and with organic material in water to form chlorinated organic chemicals.
Because of its reactivity chlorine is not likely to move through the ground and enter groundwater.
Plants and animals are not likely to store chlorine. However, laboratory studies show that repeat exposure to chlorine in air can affect the immune system, the blood, the heart, and the respiratory system of animals.
Chlorine causes environmental harm at low levels. Chlorine is especially harmful to organisms living in water and in soil.
