Advantages of Using Grow Bags for Marijuana Plants

Before we cover how to use grow bags for weed, let’s consider the top reasons you would choose to do so. Here are the main advantages that grow bags offer you when growing cannabis plants:

  • Airflow: Grow bags allow for better air circulation than any other container style. The fantastic airflow that grow bag materials allows for makes root rot, fungal infections, and other moisture-related issues far less likely.
  • Drainage: While weed plants often prefer plenty of water, they should not grow in soils that are waterlogged. The permeable nature of a grow bag always ensures proper drainage.
  • Temperature Moderation: One of the top advantages grow bags hold over other containers is their ability to moderate temperature. The same material qualities that allow for airflow and drainage help prevent sudden temperature changes, which allows for a more consistent growing environment for your plants.
  • Root Pruning: When a plant outgrows a standard container, it will become rootbound. However, that issue is much less common with fabric grow bags as they promote root pruning to keep your plants healthy and expanding.
  • Mobility: This benefit is true of nearly any type of container and is particularly important when growing weed plants. The mobility of fabric grow bags allows you to move your marijuana plant to different locations in accordance with their growth stage and their preferred growing settings.

As you can see from the list above, grow bags offer many advantages whether you are growing weed plants or not. Now let’s move on to the more practical matter of how to use grow bags for weed plants.

How to Use Grow Bags for Growing a Cannabis Plant

While growing cannabis in grow bags is not difficult, there are a few factors you should keep in mind. The next few sections will introduce you to a few vital insights that will help your marijuana cultivation ventures be as successful as they can be.

Choose the Best Grow Bag for Your Ganja Plants

The best grow bags on the market today consist of non-woven fabrics that not only allow for incredible air and water circulation but are also highly durable and long-lasting with the right care. If you can find a grow bag that meets those criteria, you’re off to an excellent start. However, there’s one additional question that is crucial to choosing the best grow bag for you.

What Size Grow Bag is Best for a Marijuana Plant?

The size of grow bag you should use depends on the current growth stage of your marijuana plant. For example, marijuana seedlings should grow in a small starter kit. After your plant surpasses the seedling stage and begins to develop roots, you can transplant it to a grow bag. 3-gallon and 5-gallon grow bags often work well for young plants, while mature plants may need bags that are 10-gallon or larger.

Fill Your Grow Bag with Healthy Soil

The soil you add to your grow bag is as important as the quality of the grow bag itself. Each plant you grow will have specific preferences related to soil content, and cannabis plants are no exception. Generally, marijuana plants prefer to grow in loam soils that have a suitable balance of drainage and water retention.

Occasionally, you may need to supplement your grow bag soil even if you started with a healthy mix. Soil amendments ensure that your soil maintains its structure and can supply the right nutrients for your cannabis plants.

You’ll find that there are many different types of synthetic fertilizers that are specific to growing marijuana. These fertilizers include varying amounts of nitrogen, phosphorus, potassium, and various micronutrients. Different nutrient ratios are often better suited to certain stages of cannabis cultivation.

Additionally, you can also use organic fertilizers to improve the soil quality of your marijuana plants. A few examples of these options include manure, compost, and worm castings. Living soil is also popular among growers. Each of these materials adds organic matter to you grow bag soil and helps promote vigorous growth for your cannabis plants. 


Move Your Grow Bag as Much as You Need

Growing marijuana plants in containers allows you to move your plant as much as you need. For instance, many growers keep seedlings and young marijuana plants in indoor grow rooms. Then, in summer, they may choose to move their plant to an outdoor growing location.

Those who grow marijuana outdoors also may choose to bring their plants inside at night to protect them from cool temperatures. The advantage for fabric grow bags is that you’ll have little trouble at all moving your plants to give them the best growing conditions. 

Choosing the most advantageous position for growing cannabis also depends on your ability to understand what growth conditions are most suitable for marijuana cultivation. Once you know those requirements, you’ll have a clearer understanding of where you should locate your grow bag.

Ideal Grow Conditions for Marijuana Cultivation in Grow Bags

If you’re struggling to decide where to grow your marijuana plants, it helps to review the basic growth requirements these plants have. Generally, most ganja plants will grow best when they are in the presence of:

  • Air temperatures between 60- and 90-degrees Fahrenheit
  • Ample daily light, whether outdoors or under grow lights
  • Relatively high humidity between 40 and 60%

If you can find those conditions in an outdoor setting, your marijuana plants are likely to grow well. Alternatively, you can recreate those growth conditions by growing weed indoors using a grow tent or an indoor grow room. In either case, using grow bags will allow you to move your cannabis plants to an area where they have the best chance to thrive.

FAQs about Growing Cannabis Plants

Growing marijuana is a process that is unfamiliar to many, even those who have experience with other forms of gardening. That lack of experience leads many potential weed growers to have many questions about how to raise their cannabis plants properly. Below are some answers to a few of the most common of those inquiries.

What is the best acidity level for growing cannabis plants?

Typically, marijuana plants prefer soil that is slightly or moderately acidic. A pH range of 5 to 7 will usually permit one of these plants to survive. However, a pH level that falls between 5.7 and 6.2 is often preferable and will make for the best growth. Marijuana plants that grow in alkaline soils may show limited growth and can experience chlorosis as well.

How often should you water a marijuana plant?

Compared to other plants you might choose to grow, cannabis plants tend to need a relatively high amount of water. At times, you may need to supply water for your plants every one to two days or every two to three days. However, one of the best ways to know if your marijuana plants need water is to feel the soil. If the first inch of soil is dry, give your plant more water.

If you choose to grow your cannabis plants in fabric grow bags, you should remain prepared to give your ganja plant more water than you would if it were growing in another type of container. The permeability of grow bags allows water to drain quite effectively. While this is overall a benefit, it can mean you’ll need to water more often when growing moisture-loving species such as pakololo plants. 

What kind of water is best for growing cannabis?

Standard tap water should work well for your cheeba plants. However, there is a better alternative you can use. Distilled water may be the best option for dagga plants as it is much less capable of spreading harmful toxins to the soil. Tap water, on the other hand, can be somewhat impure, which could hinder your marijuana plants on a rare occasion.

Why are my cannabis plants turning yellow?

Bud plant leaves often turn yellow when they are not getting the correct amount of soil nutrients. For example, a cannabis plant that gets too high a volume of soil nutrients may experience nutrient burn, one symptom of which is yellow leaves. By contrast, a lack of nutrients can cause the same effect. However, you should know that yellow leaves can be a sign of several problems in plants, such as poor drainage.

Should you cut off yellow leaves on marijuana plants?

Removing yellowing leaves will not usually cause harm to your plant and can be beneficial as well. For example, removing those leaves will allow light to reach other non-yellowing leaves more easily. Selective pruning can also help prevent disease in your cheeba plant.

Final Thoughts on Using Grow Bags for Growing Cannabis

Knowing how to use grow bags the right way for cannabis plants will go a long way towards ensuring your plants remain healthy and produce an ample harvest.
