Why use reverse osmosis water for growing cannabis? Did you know that the H2O that comes out of your tap is not suitable for growing marijuana in most cities?
To begin with, city water contains chlorine to kill bacteria and other microorganisms. At the very least, this makes your plants taste horrible. In addition, chlorine has been known to damage certain types of roots, especially delicate white root hairs.
What is Reverse Osmosis Water and How to Use it for Growing Cannabis?
Now, I’m not saying that you shouldn’t drink chlorine H2O. You can make it work with the right conditions. However, de-chlorinated is undoubtedly recommended if you want to grow killer weed.
Another problem with city water is fluoride. Yes! Cities put chlorine in their supplies, but they also put fluoride in their water supplies. You can’t see it, and you might not taste it, but there’s fluoride in the stuff that comes out of your tap!
For some good news:
Reverse osmosis (RO) is an effective method for removing chlorine and fluoride. At the same time, RO also filters out just about every other chemical and particle in the water except for H2O molecules.

Suppose you’re considering buying a reverse osmosis system. You might also want to consider this: The membrane used in RO filters will eventually clog with particles and therefore reduce its ability to filter out contaminants. Of course, this depends on how much you use it, but the rule of thumb is that you should replace your membrane every dozen years or 2,000 gallons.
It’s also worth mentioning that RO systems are not cheap.
If you’re looking to save money, there are alternatives that I’ll go over in another article. Nevertheless, if you want clean H2O for growing weeds, read on.
There are several ways to get reverse osmosis H2O. The first way is to buy a RO system for your home, but these can be expensive and time-consuming if you want to clean large quantities of H2O. If you already have one, then great! Go ahead and use it.
If you’re looking for an easier way to get reverse osmosis water, a product called the “Water Wand” might be right for you.
The Water Wand is a hand-held device that allows you to “wand” your tap water and drink it without taking in pollution from the environment or chemicals from your pipes. In other words, you can use it to test H2O from your tap and make sure that the H2O you put in your RO system is clean.
In addition, you can connect a hose directly to the Water Wand and pour purified water into exposed soil without using a bucket. This allows the plant to drink as much as it wants and doesn’t waste any water near the roots.
Water is a crucial element of life, and it can’t be stressed enough how important clean H2O is to growing weed.

You don’t have to go out and buy a reverse osmosis system, but you should still think twice before filling up your watering can from the kitchen sink. If you want clean, filtered RO H2O that will make your plants grow, check out the Water Wand.
