SOLUTION: A successful water treatment system will usually include carbon filtration to reduce or remove chemicals and heavy metals. The systems should also include catalytic carbon which successully removes chloramine added by municiplaities. Many growers utilize two columns of carbon:

By far and away the best way to grow legal cannabis in the USA is to do it in a state where it has been legalized. Prison time is not conducive to to growing a booming business. Well… duuuuhhhh! Seriously, there are many “best practices” when it comes to growing cannabis successfully and profitably. However, we are here to discuss what growers can do to increase their yields and profitability by growing cannabis with high quality water.

Often overlooked, chemicals and heavy metals are almost always detrimental to any plant, especially cannabis, as well as people who use the product. These include arsenic, nitrates, nitrites, chlorine, chloramine, PCB, TCE, dioxin, glyphosate, lead, cadminum, mercury, chromium, and many, many others. Heavy metals accumulate in parts of the body, and are not easily eliminated. Arsenic contaminantion is much more common than most people believe and small amounts can be deadly. Plants naturally absorb arsenic and store it in their tissues.

I can’t write it any better than the Royal Queen Seeds Blog, so here is how they phrased it:

Chemicals & Heavy Metals

Not surprisingly, water is frequently overlooked as a critical component of growing cannabis. After all, many people feel that if water is safe to drink, it must be safe for growing plants. Before we can decide how to treat the water, we must first understand the role that water plays in growing any plant, and especially cannabis. Cannabis is approximately ninety percent (90%) water, so it would be difficult to overstate the important role water serves in growing the plant.

I guess I just don’t understand what your criteria is for “better.”

As far as the Brita filter goes, I am not sure about it removing chlorine, but that is cool if it does. It should lower the amount of TDS, giving you a lower base PPM or EC to start with, so that there is more leeway for adding nutes before you reach a toxic level of TDS that your plants cannot handle.

That’s me. I fill 3, gallon milk jugs about once every 3-4 days. I deal with a high pH and sitting out does NOT change that, but when I was at the hydro shop last time, they gave me a free 8oz bottle of pH neutralizer. Pick up a bottle of that, it is cheap. I only use a few drops and it lowers my pH from the 8’s down to 7.0 flat, then I add a small amount of nutrients to every watering (I know that’s not normal but it works for me ) and retest it and it comes out at about 6.0-6.5.

I suppose in a state like yours filtering the water would be better because they add tons of chemicals to municipal water supplies, but out here it’s all from aquifers and wells so most of the non-water substances in our water are basically just more nutrients

The nice thing about the neutralizer is that if it’s an acidic solution it will bring it back to 7, and if it’s alkaline, it will also bring it back to basic.

Are you considering adding a water filter to your garden? Honestly it is not a bad idea. I have been using a cannabis water filter for years and I think it is totally worth it. This is especially true if you want to grow as clean and organic as possible. Depending on where you live, tap water usually is high in salts, metals and chlorine. Salts, metals and chlorine are definitely not good for your plants or the biology in your garden. Chlorine is known to kill the beneficial microbes, fungi and bacteria that live in your garden. There is also evidence suggesting that chlorine slows root development. To improve your growing environment, I recommend adding a garden hose filter.

Side Note:

A lot of growers use Reverse Osmosis filters. Reverse Osmosis is a water purification technology that uses a semipermeable membrane to remove impurities. RO filters are great at removing salts, metals and chlorine. In fact, they pretty much remove everything from your water. On the other hand, RO filters are extremely wasteful. For one gallon of clean water, most RO filters waste between two and four gallons. Some older models are worse!

In my opinion, a better alternative to a RO filter is a carbon filter. I prefer using carbon filters because they are cheap, easy to use and work great! Carbon filters screw right into your faucet or hose. Amazon is definitely the best place to buy these filters. After researching the difference between competing brands, I determined that the cheaper models were nearly as effective as the expensive models. For me, the choice was easy. I choose the Camco Tastepure because it offers the best performance for the cost. I discovered that some brands sold the exact same filter but for way more money. Camco on the other hand, sells their filters in two packs. A two pack will run you $18! Camco recommends changing your filter every 3 months, but this obviously depends on how much you use it.
