Water is essential for cannabis plants’ sustenance and light and minerals. It not only aids in photosynthesis but also maintains a cool internal temperature for the plant.
The most crucial function is that water transports all the nutrients in the soil to the roots so the plant can use them. We must be careful to hydrate the crop using only the most appropriate type of water since the kind of water we employ significantly impacts plant nutrition.
This post will examine several forms of water, how they impact cannabis plants, and the optimal water temperature for cannabis plants.
We will also learn how to balance and fix typical water issues for the best possible growth. To learn more about the best water for marijuana, continue reading.
Considerations when Choosing the Best Water for Growing Cannabis
Water PPM for Cannabis Plants
PPM, or parts per million, is a unit of measurement for the number of minerals in the water. Milligrams of contamination per liter are measured in PPMs. The optimal PPM for cannabis water is between 500 and 600 in the seedling stage and early vegetative stages.
In the late vegetative stage, between 800 and 900, and during the flowering stage, between 1000 and 1100. Both soil and hydroponic systems have comparable requirements. However, different strains may have different needs. Always examine the requirements of the cultivar of your choosing.
Can you Water Cannabis with Hard Water?
The quantity of soluble mineral salts in hard water is exceptionally high and includes calcium and magnesium. Milligrams of calcium carbonate per liter or ppm are used to assess hardness.
Cannabis growing issues might be experienced upon the use of hard water. Nutrients from the plant can no longer be collected adequately due to calcium deposits in the roots. The provided nutrient may then have minimal or no intended impact.
Can you Water Cannabis with Soft Water?
The amount of calcium and magnesium-rich rocks and soil that soft water has come into contact with is much lower.
The ideal water for humans to drink or to feed plants is soft. Anything with a pH of 7.8 or lower and a ppm concentration of less than 17.1 is considered soft water.
Water pH for cannabis
The pH scale, with 0 being the most acidic and 14 the most alkaline, determines how acidic or alkaline your water is. Water with neutral pH is 7.
Since cannabis develops best in the pH range of 6-7, several cannabis farmers will spend significant time concentrating on pH. The pH directly affects how well your plant growth is doing. If the pH is too strong, for instance, your plants won’t be able to absorb iron. Similarly, too low of a pH will prevent your plants from getting enough calcium or magnesium.
Adjusting pH in the water
You must make a timely adjustment if your nutrient, soil, or Water pH is far outside the ideal range. You can accomplish this by using “pH up” and “pH down” solutions available at any grow shop. Naturally, you will need to add some pH down if your pH is too high, and vice versa.
Water Temperature for Cannabis Plants
The appropriate temperature ranges for cannabis should be discussed first. This element is the easiest to understand and will gradually allow you to enhance your gardening abilities.
68° to 73° F is the best water temperature for growing weed. Water holds less oxygen as it grows warmer. The roots can breathe and stretch because of the oxygen around them.
The root zone is placed in an anaerobic environment due to inadequate oxygen levels. Due to this configuration, it is more likely that crops will contract infections like pythium, which stunts crop growth.
The other extreme is also undesirable. Cannabis watered at temperatures cooler than 55° F shocks the plant, lowering its metabolic ability and bud production and growth are hampered.

What Type of Water is Best For Cannabis?
Unfiltered tap water, it is often believed, will damage your plants. Despite some explanations, it is not valid. First, tap water quality varies greatly from one town to another.
Cannabis won’t endure very long if your area has calcium and magnesium salts in addition to the hard water with high chlorine content. However, removing the chlorine should be straightforward if you let the water sit for a day or longer.
Rainwater
In general, giving your healthy plants rainwater is the best option. Once you have paid for the storage container or containers, it is free and largely contaminant-free.
However, don’t be fooled by claims that it is pH neutral and completely pure. This is only the situation in a relatively small number of places on the earth because of human pollution.
Rainfall typically contains slight acidity, so plants have a brief growth spike following a heavy downpour. The acid will neutralize if you let it sit for a little, which is typically the case when growing indoors. Either way, you should test the pH to ensure it is within the range that weed plants prefer.
Distilled Water
Are cannabis plants appropriate for distilled water? While soft water from reverse osmosis and other sources aren’t ideal, they make a great flat base.
If you can afford it, use purified sources and add nutrients to them. You maintain total control over all three variables by bypassing toxic compounds in tap and rainfall.
Signs of Water Issues in your Plants
People frequently overwater their plants, and a few simple changes might help you create a better landscape. Overwatered plants can still be saved and prosper in your landscape after being detected. To aid you in seeing whether there is too much water in your environment, we have put up a list of four symptoms to look out for.
- Yellow lower leaves make the plant appear withered.
- There won’t be any new growth or rotten roots.
- Young leaves will seem brown, and the soil will look green (algae).
- The symptoms of plants with too much water are similar to those with insufficient water.
4 Tips To Give Your Cannabis The Best Water
Automatic Watering
While installing an autonomous irrigation system may appear complicated, it is simple to perform and can save you time and energy when growing cannabis indoors. You may water numerous times daily with an autonomous irrigation system without physically turning on or watching over your equipment, saving you time and labor.
Watering Frequency
So, once the surface of the soil or developing medium feels dry, you should water your cannabis plants.
- When the earth feels dry up to your first knuckle, water plants (or if the pot feels light).
- Plants in coco coir should be watered every 1-2 days. Try providing less water at a time till plants get bigger and start consuming more if the coco coir is staying wet for more than three days.

Runoff Water
A fertilizer solution that passes through a plant’s soil is collected as runoff. To catch the extra nutrition solution that has traveled through the container containing the root zone in a potted plant, a plastic dish or tray is positioned under the container.
We routinely analyze the pH and EC of this runoff solution to see if our subsequent nutrient delivery needs to be adjusted.
For cannabis to produce healthy, intense blooms, the appropriate amount of water and nutrients must be used. High-quality nutrients can be used with these water sources which include all the nutritional requirements for cannabis growth.

How Much Water Does a Weed Plant Need?
A weed plant needs a considerable amount of water to survive, but the exact amount depends on many factors. The type of weed, climate and soil conditions all play a role in determining its water requirements. In general, most weeds prefer moist soil with consistent moisture levels. If grown outdoors, they should be watered deeply once or twice a week depending on weather conditions. A good rule of thumb is to give them approximately 1 inch (2-3 cm) of water per week if possible; however, this can vary significantly from one area to another depending on environmental factors such as temperature and rainfall patterns.
The ideal way to keep your weeds hydrated is by using mulch around them or by providing consistent deep watering sessions that allow for some runoff at the base of each plant when needed. Mulching will help retain moisture in dry climates while reducing evaporation in wetter climates because it acts as insulation against high temperatures and direct sunlight exposure which can quickly dry out the soil even during periods with regular rainfall amounts.
Weed plants also have different root systems, which play an important role in their ability to absorb and store water effectively throughout their entire life cycle – shallow rooted varieties require more frequent irrigation compared to those with deeper roots, which are better adapted for longer periods between watering sessions due to their greater access underground resources like moisture reserves stored further down into the earth’s surface layers.
Furthermore, larger marijuana plants tend to need more than smaller ones since they are able to draw upon larger volumes of available groundwater sources over time without additional top up applications being required from you as frequently as small sized specimens would require under similar circumstances.
Overall though there isn’t really one definitive answer when it comes exactly how much water does a weed plant need since so many conditions must be taken into account before formulating any accurate advice about what might work best for your particular situation – therefore it is always wise seek expert assistance if unsure about anything related this subject matter so you don’t inadvertently damage what could otherwise become thriving specimen given optimum care!
How Often to Water Weed
It is important to water your weed plants correctly in order to ensure that they stay healthy and produce a good yield. Generally, you should water your marijuana seeds once every 2-3 days. This will give the soil enough time to dry out between watering sessions and will encourage deep rooting of the plant. When it comes time to water, make sure that you use room temperature or slightly warm water as cold temperatures can shock roots and stunt growth.
Additionally, be sure not to over saturate the soil; instead allow for adequate drainage so that oxygen can reach the roots of the plant which is essential for healthy growth. It’s also important to monitor how much moisture is in the soil before each watering session using a moisture meter – this will help you determine when it’s necessary and how much water your weeds need at any given moment. Lastly, if possible try adding a few drops of liquid fertilizer when you’re watering – this will provide nutrients directly into their root system which are needed for optimal development during all flowering stages of growth!
How To Tell If Your Plants Are Thirsty
If you’re wondering if your plants are thirsty, there are a few telltale signs to look for. The first thing to do is check the soil. If it’s dry, chances are your plant needs water. You can also lift up the pot and feel its weight; if it feels light, this could be an indication that it hasn’t been watered in a while. Another way to tell is by looking at the leaves: droopy or wilted foliage often means your plant needs more moisture. Lastly, yellowing leaves may signal overwatering or underwatering depending on how they appear so pay close attention here too! All of these cues should help you determine whether or not your plants need a drink – remember to be patient with them as they adjust over time and never forget to give them some love!
Overall, there are a few simple ways to tell if your plants are thirsty: check the soil, feel the pot’s weight, look at their leaves and pay attention to any yellowing. With these tips in mind, you can give your plants exactly what they need and keep them happy and healthy!
How To Water Your Cannabis Plants
Watering your cannabis plants is an important part of the cultivation process, as it helps to keep them healthy and vibrant. Without proper hydration, many issues can arise that can hinder the growth of your crop. It’s essential to provide water in a timely manner – too much or too little will have negative consequences.
The first step to watering your cannabis plant is determining when it needs water. As a general rule of thumb, you should check if the top two inches of soil are dry before adding more; if they are wet then wait until they become slightly dry again before adding more water. If you’re growing in containers or pots, be sure to lift one up every now and then to see how heavy it feels – if it’s light in weight that means there isn’t enough amounts of water inside so add some more!
When you do decide to irrigate, make sure the pH levels aren’t too high or low for optimal absorption by taking readings with a digital meter. The ideal range for cannabis is 6-7 on the pH scale (which measures acidity). You should also take into account what type of medium your crop is grown in (soil vs hydro) as this impacts how often you need to water them – soil grown crops typically require less frequent watering than those grown using hydroponics systems.
Some tips: Water only when necessary and avoid over-watering at all costs! Doing so can lead to root rot which will stunt growth and eventually kill off your marijuana plants altogether; use lukewarm tap water instead cold/hot temperatures might shock their system; feed young cannabis seedlings once per day but reduce frequency as they get older; create drainage systems around each pot so excess moisture doesn’t build up near root rots – this ensures good air circulation which further prevents diseases from developing within soil mediums like fungal infections etc. Finally, always keep an eye on daily fluctuations between daytime/nighttime temperatures since warm days tend require more frequent watering than cooler ones do!
When to stop watering before harvest
It is important to stop watering your crop before harvesting in order to ensure the best quality and flavor of the final product. As harvest approaches, gradually reduce the amount of water you give your plants so that they can start focusing energy on ripening their fruit or vegetables. The amount of time you need to stop watering before harvesting depends on what kind of crop you are growing. For most crops, it is recommended that you cease all irrigation at least two weeks prior to harvest. This will allow enough time for the plant’s cells and tissues to mature fully, giving them a richer flavor and texture upon consumption.
Additionally, allowing your plants some extra “dry-off” time helps prevent decay due to excess moisture during storage or transport after being harvested. If you have any doubts about when exactly to cut back on watering before harvest season arrives, consider consulting with an experienced grower who can provide advice tailored specifically for your particular situation.
How To Collect Water Runoff
1. Install a rain barrel or cistern: A rain barrel or cistern collects water runoff from your roof and stores it for later use.
2. Use swales: Swales are shallow trenches that redirect water away from hard surfaces like driveways and sidewalks, allowing it to infiltrate the ground instead of running off into storm drains.
3. Plant native vegetation: Native plants thrive in local conditions and can help slow down the flow of water by absorbing much of it before it runs off into nearby waterways.
4. Install green roofs: A green roof is a layer of vegetation planted on top of a building’s structure that helps absorb rainfall before it runs off as runoff.
5. Build permeable pathways: Rather than using solid concrete or asphalt, build pathways with permeable materials like gravel, grass pavers, or porous pavement so water can easily seep through them instead of running off elsewhere..
How To Water Cannabis Plants When You’re Away
If you’re going away and need to water your cannabis plants, there are several ways to do it. The first is to use drip irrigation systems or self-watering containers that can be set up before you leave. These automated systems will keep your plants watered for a set amount of time so that when you come back, they’ll still be healthy and thriving.
Another option is to ask a friend or family member who lives nearby if they can check in on the plants while you’re gone. They can then water them as needed and make sure everything stays in good condition until you get home. Lastly, try setting up large buckets of water near the plant roots which will slowly seep into the soil over time instead of having one big watering session right before leaving town.
