Top Tips on How You Can Make Your Cannabis Buds Dense

How To Grow Cannabis With Dense Buds

It is not one factor that affects the density of your cannabis buds. It is various factors from the strain of cannabis to the type of light and nutrients you provide your plants. Most of the time, the most significant reason plants grow and develop airy buds, is because of neglect by the grower. It can be due to insufficient nourishment or not regulating the temperatures of your grow room, among other reasons. With worse conditions, how the plants grow, and the amount of harvest is put to question.

What things can you do to overcome your situation and start growing buds that are dense?

The Amount and Strength of Light

As a cannabis grower, you have to admit that sometimes you may have problems with your lights as they underpower delivering a small amount of light. The light may be sufficient during the growing phase of cannabis. The big problem is that different plant stages have different light requirements in terms of the wavelength. When a grow lamp is under-powered, it may not deliver the required type of light for the flowering stage. It then affects the development of buds. When the buds do not receive the right amount of light, they will not thicken or become dense even if the whole plant is still healthy.

The length at which you place your light bulbs from the plants may also affect the size of your buds. How far away from your plants do you put your grow lights? Depending on the type of light, there is a distance that is right for every grow lamp. An example, when using CFL or Fluorescent bulbs, you should hang your lights only a few inches away from the plants if you want to grow dense bulbs. When using LEDs, you should consult the manufacturer since all models are different. You should be careful that there are some very powerful LEDs. If you place them too close to the plants, you may end up scorching your plant leaves and destroying your buds. A good way you can determine the right distance to position your light is by placing your hand under the lamp. If your hand feels unpleasant due to the warmth of the light, then it also feels the same for the plants.

Some Best Led Grow Lights For Grow Marijuana:

The Color of Light

Color of Light

When choosing a grow light, you should prioritize lights that produce the colors yellow, orange, and red as they tend to help buds grow and become dense. Their color closely resembles the reddish light from the sun. During the flowering stage, cannabis plants utilize the red frequencies of light more efficiently than any other frequency. Therefore, you can search for an excellent high-performance bulb that can produce 660nm when your plants are in bloom to help with the development of the density of the bud. Even so, marijuana can work pretty well with any spectrum of light. It just needs to deliver the right amount of brightness. You can increase the intensity of light by acquiring a good reflector and reflective walls that will bounce back the light to the plants providing enough coverage. Additionally, it is best to place the lights at the top of the canopy. However, it should be at a non-destructive length to the plants. It ensures that all the buds and bud sites receive plenty of light for them to grow and become dense.

Optimal Temperature and Heat

Optimal Temperature and Heat

When growing cannabis, you have to make sure that the growing environment has the right temperature range for the best development of buds. You should always ensure that at night, the temperatures do not drop too low, and during the day, they do not exceed 85 degrees Fahrenheit. They should still lie in the range of 70 to 80 degrees Fahrenheit. When the temperature exceeds 85 degrees, they can lead to the development of airy buds. While you need to have control over your heat, choosing the best strain to grow can also help make the difference. If you live in a cold region, you can select an Indica strain since they are good at handling the cold. Sativa strains are best for growing in the equatorial region as they adapt well to the heat. When your buds are exposed to too much heat, they can become thin and develop strange growing patterns. The cold temperature during the first six weeks of flowering can make your plants produce airy buds that do not increase in size or density.

The Humidity Levels

Just like temperature, you need to ensure that the level of humidity in your grow room is in the right range. When your cannabis plants enter the flowering stage, you should never allow the level of moisture to be more than 60 percent. During the final two to three weeks of harvesting, you should reduce the levels to 45 percent gradually. By doing so, the plants will try to find ways to protect their flowers hence developing denser buds that contain a high amount of resin. By reducing the level of humidity, you can protect the buds from the development of buds.

Feeding the Plants

For your plants to grow big and dense buds, you need to provide them with some external stimulus that can give them increased energy such as nutrients. You have to ensure that you feed them only the right amount of nutrients throughout all the growth stages. You should not use a general plant nutrient on weed. Most of these carry nutrients that are high in Nitrogen which would not be suitable for use during the flowering stage. It can lead to the development of small buds, an exact opposite of what you intend. During the flowering stage, your plants require a minimal supply of Nitrogen, plenty of potassium, and just the right amount of phosphorous. With that, your plants can develop healthy and dense buds.

During this stage, you should avoid getting too much Nitrogen since it will lower your plant yield and increase the development of airy buds.

Improving the Airflow and Spacing

When growing your cannabis, always ensure that there is plenty of spacing around the buds. It helps them grow and big as possible without any hindrance or stress, enabling them to reach their potential. If you notice that some branches or leaves are hindering the buds from receiving light, you should employ low-stress training techniques on the plants. The process involves bending the branches of the plant in a rather beneficial way to the structure of the plant. You do not have to break or cut any. You should also improve the airflow of your grow room by setting up fans and ventilations.

Providing Support to Plants

Depending on the type of plants you are growing, most of them at one point will require you to provide them with support for them to grow to their maximum ability. Marijuana is not left out. Regardless of whether you are growing your cannabis indoors or outdoors, when you support it, you will help the plants develop significantly. There are various tools and methods you can use. It all depends on the current condition of your plants.

Marijuana plants are well known to have weak stems. You may, therefore, require to provide them with support to add on the strength of bearing the weight from the buds. Also, when practicing indoor cultivation of cannabis, and you are using a hydroponic system to provide the plants with water and nutrients, you need to give the plants with a support mechanism since there is no soil to provide plant support.

Using A Good Size Container

The size of the container you choose to grow your cannabis in can ultimately affect the size of your plants and the size of buds it will produce. A small container can only handle a small plant. They can also only support little buds. When purchasing the pot you want to use, you should always have the result that you intend to achieve in mind. If you plan to grow a big plant that will only have big buds, you should therefore only purchase the big size container.

You can as well use air pots that will help increase the growth rate of your plants. An air pot contains small holes where your plant roots can suck in oxygen from the air. They also help to prevent roots from binding when they grow in a tight and enclosed environment.

Preventing Overwatering


The roots of cannabis require both oxygen and water to grow. You should always be careful with the amount of water you provide for your plants. If you want your plants to grow with thick and dense buds, you need to provide them with just the right amount of water for them to use the oxygen in the growing medium air pockets and the water itself in growing.

When you provide your roots with too much water, the excess water will fill out the air pockets in the growing medium, reducing the amount of oxygen the plant’s intake. Your plants will start to develop curly or droopy leaves and failing bud integrity. Watering decisions are one of the most important when growing cannabis since it also is responsible for the delivery of nutrients, especially in a hydroponic grow system.

The Time of Harvest

One complicated situation that you need to learn how to identify and maneuver as a cannabis grower knows the right time to make your harvests. When you do it too early, you will reduce your yields, and your buds will become airy and poor. It will also reduce the potency of the buds. Users that smoke the cannabis from such early –harvested buds may experience headaches after use. You should avoid harvesting cannabis whose buds still have white pistils and are sticking out. The buds should be nature and thick for you to make a move. By creating an excellent, timely harvest, you can give your buds enough time to thicken up and tighten.
