The Different Types of Water

When it comes to watering your cannabis plant, there are different types of water that you can use. You can use tap water, reverse osmosis water, distilled water, or rainwater. Each type of water has its own benefits and drawbacks. In this article, we will go over the different types of water and how they can affect your plant.


Cannabis plants love rainwater! If you are lucky enough to live in an area where it rains frequently, you can collect rainwater in a barrel or bucket and use it to water your cannabis plants. Just make sure that the barrel or bucket is clean and free of any chemicals that could harm your plants.

If you live in an area with hard water, rainwater can help to soften it before you use it on your plants. Hard water contains high levels of minerals like calcium and magnesium, which can build up on the leaves of your cannabis plants and cause nutrient deficiencies. Softening hard water with rainwater will help to prevent these problems.

Distilled water

Distilled water has been purified by a distillation process that removes all impurities, including minerals and chemicals. This makes it an ideal choice for watering cannabis plants, as it will not build up mineral deposits in the soil that can lead to nutrient deficiencies. It is also available cheaply and easily from most supermarkets.

While distilled water is perfect for cannabis plants, it does have one drawback – it does not contain any dissolved minerals, which can be essential for plant health. For this reason, it is often advisable to add a small amount of fertiliser to the water when using it to water cannabis plants.

RO water

Reverse osmosis water, or RO water, is one of the most filtered waters available on the market. In order to filter out all of the impurities, an RO system forces water through a semipermeable membrane. This process gets rid of most, if not all, contaminants including dissolved minerals, bacteria, and viruses. The only downside to using RO water is that it can be quite expensive to set up a filtration system in your home. If you do decide to go this route, make sure to purchase a high-quality RO system that includes a sediment filter and carbon filter.

The Best Time to Water Your Cannabis Plant

It is important to know when to water your cannabis plant. If you water it too much, the roots will rot. If you water it too little, the plant will become stressed and may even die. The best time to water your cannabis plant is in the morning or evening.

In the morning

The best time to water your cannabis plant is in the morning. This allows the plant to absorb the water and nutrients before the heat of the day. It also allows the plant to dry out before nightfall, which reduces the risk of fungal diseases.

In the evening

It is best to water your cannabis plant in the evening. This gives the plant time to absorb the water and use it throughout the night. Cannabis plants need a lot of water, so make sure to give them enough. Water them until the soil is moist, but not soggy.

How Much Water to Use

too much or too little water can both be detrimental to your cannabis plant. When watering your plant, it is important to make sure that the soil is evenly moistened without being waterlogged. The best way to determine how much water your plant needs is to check the soil with your fingers.

1 gallon of water per day

It is important to know how much water your cannabis plant needs in order to ensure its health and vitality. Different plants have different water requirements, and it is important to understand these needs in order to provide your plant with the proper care.

A good rule of thumb is to give your plant 1 gallon of water per day. This amount may need to be increased or decreased depending on the type of plant, the size of the plant, the climate, and other factors. It is always best to check with a professional or do your own research to determine the specific watering needs of your particular plant.

Over watering can be just as damaging as under watering, so it is important to monitor your plant carefully and make sure that you are providing it with the proper amount of water. If you are unsure, err on the side of too little water rather than too much. Your plant will thank you for it!

2 gallons of water per day

As a general rule of thumb, you should give your cannabis plants about 1-2 gallons (3.8-7.6 liters) of water per day. However, there are a few things that you need to take into account before giving your plant its daily dose of H2O.

First and foremost, you need to take into account the size of your plant. A small plant will obviously require less water than a large one. Secondly, you need to consider the climate you’re growing in. A hot and dry climate will require more watering than a cooler and wetter one.

Last but not least, you also need to take into account the type of soil you’re using. Sandy soils will drain more quickly and require more frequent watering than heavier clay soils. If you’re unsure about how often to water your plants, it’s always best to err on the side of caution and water them less rather than more. Too much water can be just as damaging as too little.

How to Water Your Cannabis Plant

Watering your cannabis plant is one of the most important aspects of growing healthy plants. While there is no single method of watering that is perfect for all plants, there are some general guidelines that can help you water your plants properly.

Use a watering can

Water your cannabis plant with a watering can. Fill the watering can with water and wet the soil around the plant. Be sure to avoid getting water on the leaves, as this can cause them to rot. Allow the soil to dry out completely before watering again.

Use a garden hose

The most common and simplest way to water cannabis plants is with a garden hose. If your tap water is safe to drink, it’s probably also safe for watering cannabis plants. Garden hoses are easy to find and relatively inexpensive, making them a great option for beginner growers.

To water with a garden hose, simply attach the hose to your faucet and turn the water on to the desired flow rate. Hold the hose near the base of the plant and allow the water to flow until it begins to pool at the base of the plant. Be careful not to over-water, as this can lead to root rot and other problems.

Use a drip system

One of the best ways to water your cannabis plants is to use a drip system. A drip system can be as simple or as complex as you want, but the basic idea is that you slowly drip water onto the roots of your plants. This allows the roots to absorb the water more efficiently, and it also reduces the risk of overwatering.

You can buy drip systems at most garden stores, or you can make your own. If you choose to make your own, you will need to purchase a timer, some tubing, and some emitters. You will also need to drill some holes in the bottom of your pots for the tubing. Once you have all of your supplies, follow these steps:

1. Connect your timer to your water source.
2. Run the tubing from your timer to your plants.
3. Attach an emitter to each plant.
4. Set your timer and enjoy!
