The Effects of Humidity on Cannabis

Humidity is one of the most critical factors that affect a cannabis plant’s growth. This involves a plant’s ability to uptake water, nutrients and carbon dioxide.

Ideally, the humidity level in your grow room should be regulated to best meet the needs of your cannabis plants at every stage of their life cycle. It isn’t enough to hold the humidity during growing; it must be able to be controlled when drying and curing. To avoid these struggles you can buy hash online in canada.


Temperature is one of the most important aspects to consider when growing cannabis. It influences plants’ growth, ability to uptake nutrients and water, and how well they respond to light.

During the vegetative stage, young cannabis plants like temperatures in the 70-85degF range during the day and a little cooler at night. For the flowering stage, slightly cooler temperatures around 65-80degF (18-26degC) help produce better quality buds with the best color, trichome production and smell.

Humidity is also another factor to consider, especially during the flowering phase. Lowering humidity during this period helps prevent mold and mildew from forming. In terms of cannabis storage, your marijuana will deteriorate more quickly if exposed to too much air. However, if it receives insufficient air exposure, the relative humidity rises. Marijuana should be stored in airtight containers. The relative humidity is difficult to control when keeping marijuana, whereas temperature, light, and airflow are. It is challenging to regulate the relative humidity in a humid environment. A humidity pack can be the difference in this situation. The container is filled with a weed humidifier pack, which keeps the humidity at the ideal levels and protects the marijuana from deterioration. 


Light plays a significant role in cannabis growth and yield. It regulates germination, photosynthesis, and plant architecture.

The spectral content of light affects the development of chlorophyll, which in turn generates food energy to support cannabis plant growth. It also helps cannabis plants set their internal clocks by mimicking day or night light.

Growers adjust the spectral contents of their lights to encourage a plant’s production of the proper forms of chlorophyll at different stages of growth. They do this by tuning their lighting to include greater relative concentrations of red and far-red wavelengths, which are vital for flowering, bud formation and harvest.


Water plays a vital role in cannabis growth. Aside from the apparent hydration factor, it also affects how the plant absorbs nutrients.

For starters, water needs to be clean. Generally speaking, water with a pH value of 7.0 (neutral) is ideal for most growers.

If the water is too acidic, it will stunt plant growth. Likewise, water with a high ppm of minerals can clog up the root system and reduce nutrients.

This can lead to discoloration in the leaf, which is a clear sign of an issue with hydration. Other causes can include light stress and nutrient deficiencies, so it’s best to check each before making any changes.


When it comes to cannabis, the soil is a massive part of growing. Whether you’re an indoor, outdoor, or auto-flowering grower, your plants depend on the right kind of dirt to thrive.

Soil has several properties that can make or break your harvest, including water retention, drainage, texture, and pH. Understanding all these features is critical to finding the perfect soil for your growth.

For starters, look for a good, organic soil mix containing essential nutrients in the proper ratios. 


The cannabis plant needs a variety of nutrients to grow healthy and strong. These nutrients, known as macronutrients, include nitrogen (N), phosphorus (P), potassium (K) and calcium (Cl).

The amount of each needed will vary depending on the stage of plant growth. For example, nitrogen is essential during the vegetative and bud-forming stages, while P and K are essential for root, flower, and seed development.

Besides the main essentials, plants also need several micronutrients such as boron, copper, iron, molybdenum, manganese, and zinc. They help with the plant’s growth, development and metabolic reactions and are essential for optimal plant vigor and optimum harvest quality.
