Water is food for the soul for our marijuana plants, it carries all the nutrients that our fine growing flowers will ever need. The nutrients are absorbed straight from the water directly into the roots, where they are distributed properly throughout the plant. If your water doesn’t have enough nutrients in it, your plants will starve, but water with an overabundance of nutrients will kill your plants as well. The makeup of your water (pH), rather too basic or too acidic will make it hard for the roots to absorb the necessary nutrients. So we attack the question, What is the best water for growing marijuana?
What Is The Best Water For Growing Marijuana?
Straight to the point, Rainwater, Gods water, The Creators’ water, hands down, not even a competition, is by leaps and bounds the best water for our cannabis flower. Yes, there is a difference between the rainwater that falls in the inner city, and the rainwater that falls in rural areas, this is nothing but further proof of how superior rainwater is for our precious marijuana plants (And any other plants). Rainwater checks each and every box period. The price is unbeatable because it’s free, and it has the best natural pH level and mineral content possible. Of course, just to be sure you should test the water and make any adjustments if necessary (I highly doubt it (Maybe in the inner city). Without question Rainwater is your best natural overall source of water.
What About Other Water Sources?
Well, what about other sources of water, are we saying that they are no good? Absolutely not, and let’s talk about the rest. Some will say, (I don’t know how) that these other sources of water are far more convenient for them than rainwater.
Tap water. The most common mistake in a vegan grow is the use of straight-up tap water, depending on what area of the country you live in this can be good or bad. Tap water is accessible to most, but it will definitely need some assistance. We are going to have to test the water so that we know exactly what we are dealing with, meaning what we are going to need to add or subtract to make it healthy for our fabulous flowers. Your city should have a record of their water quality, but regardless of this, we still must do our pH and TBS testing. Fluoride and chlorine are not nutrients that are plants need or desire for that matter, we must definitely remove the components out of our tap water. We can simply let the water sit for 24 hours and that will take care of the chlorine, but some governments in an effort to save money use chloramine instead of chlorine, chloramines do not naturally evaporate. This means that we will have to filter the water, this is best done by using a charcoal filter to get rid of the chloramines. Reverse osmosis filtering or distillation will also rid our water of the unwanted chlorine or chloramines. Fluoride, however, is a different story. We will need to filter fluoride out by using an activated alumina filter or again reverse osmosis and distillation also helps to remove fluoride.
Distilled water: distilled water contains no nutrients, it is like a blank canvas, so we are going to need to add nutrients because water with no nutrients will steal nutrients from the soil and our plant. This is the only drawback of distilled water, because it is distilled, we know that it doesn’t contain contamination and we can control exactly how much and what minerals we choose to add.
Bottled water: bottled water can be a decent source for our marijuana grow but the cost is high. Our belief is that bottled water is even-steven with tap water containing some of the same traits, and needing some of the exact same treatments.
Purified water: purified water is just that, purified, it has no mineral content at all. So of course we are going to have to add all the nutrients that are precious plants will need before we can water them with this water source. This is another situation where if mineral-free water is poured into our fabulous soil, it will absorb more minerals away from our cannabis roots.
Springwater: in my opinion, and the late great doctor Sebi’s opinion, spring water, which is alkaline, is the best water for the human body. Springwater is also a pretty good source of water for our marijuana plants, for spring water is generally groundwater, translation; it can vary greatly from one spectrum to the next. Like all water, you surely want to test it before used to find out the exact pH level and the mineral content, and just like most of the water, we will have to make adjustments as needed before pouring the precious water on our cannabis plants.
Mineral water: mineral water is just that, it is water with a high mineral content. Mineral water is very expensive. Your tap water contains minerals and costs far less. Let’s be clear, mineral water is not bad for your cannabis plants because it does have great mineral content, but it is not cost-effective In any way shape form or fashion.
Well water: Well water is very interesting, of course like all the other waters, It must be tested first. We must know what minerals are contained, and the pH level of the water. You will have to adjust the levels to match exactly what it is you are trying to do.
Rainwater: again, I cannot stress enough Rainwater is simply the best type of water to give your precious plants, it’s cost-effective, it’s free from contaminants and depending on what part of the country you live in or where you are located, It generally requires very low maintenance. Rainwater is usually a little acidic, this is almost like a steroid to most plants, which is why you see them have a growth spurt after it rains. Simply letting Rainwater sit for a 24-hour period will pretty much neutralize the acid in the water, but as you know, we must still test our water
Will There Be A Test?
Any water source that’s not pure distilled water needs to be tested. pH levels and the mineral content is what you consistently hear from us, because those things are crucially important in feeding our fantastic flower. Once tested, if the water isn’t ideal, we will need to make some adjustments. Quick trick/tip; You can purify any water completely using reverse osmosis, how, with a basic filter system, or by distillation. These things will remove all minerals and most nutrients from the water, leaving you a blank canvas so that you then add in the ideal level of nutrients and create the best pH levels.
A pH meter is of the utmost importance, we need our numbers to be between 6 and 6.8 when we are growing in the ground or even in pots, and we need it to be between 5.5 and 6.5 if we are dealing with hydroponics. Are we looking for an exact number? Great question, and the answer is no, we just need to keep our levels within the aforementioned numbers. Unless we are using pure distilled water we must test the water, even rainwater, so that we can track our levels.
How do we test our pH levels, if we have an indoor grow, we test what is called the runoff water, What exactly is runoff water? (You ask great questions) runoff water, is water that did not get absorbed into the soil or snatch by the roots, but did not evaporate, and therefore made its way from the plant into some places that water collects. Our wonderful soil behaves like a filter or a natural buffer, so the pH changes in our water don’t have a large influence on the pH levels near the roots. However, if you are cultivating a hydroponic grow, pH changes in the water have an almost immediate effect on our fabulous flower. There are many ways to raise the pH level in our water, some use garden lime, and some use products like Gen. hydroponics pH control kits. You can use simple white vinegar to lower your pH level
Adding and Subtracting
How do we adjust the mineral content of our water? It is best to use A TDS (total dissolved solids) meter to test the mineral content of our water, it also gives you levels on a few other things, but in this post, We are concentrating on our water. We measure mineral content in parts per million, commonly known as PPM. If you are using tap water, it should always read between 50 and 300 ppm, but never over 400 ppm. As the stages of our flower changes so should our ppm levels. After cloning our fickle little flower likes to get 500 to 600 ppm, but while vegging it should be around 800 to 900 ppm, and we top out at about 1000 to 1100 ppm when we enter into our flowering stage.
We can lower the PPM’s in our plant, by using products like Gen. hydroponics flora grow, micro combo fertilizer set. Please be mindful that there are many other products available for use. Even if you have what is called hard water, where your water measures over 400 ppm
Not to Hot And Not Too Cold
Does our marijuana plant care about the temperature of its water? Why yes it does: the best water temperature for our marvelous marijuana plant is between 68° and 73°F. We want our roots to properly absorb the nutrients, so we cannot make our water too hot or too cold.
If we are mindful of the things that we have learned in this post about the water, we will be able to properly feed our babies from germination to vegetation and end up with a most prosperous vegan grow.
