humidity for growing weed indoors

As your indoor weed plants grow, they’ll need less attention, but you’ll still need to check up on them every 2-3 days.

Examine the tops and undersides of leaves for pests or discoloration—spider mites live on the underside of leaves—as well as stalks and branches. Also, check the soil for pests.

If your space is too humid, you may need to invest in a dehumidifier—also known as “dehueys.” However, keep in mind that while dehueys will reduce humidity, they typically increase temperature—you may need more fans or an AC when adding a dehumidifier.

Good soil for cannabis relies on a healthy population of mycorrhizae and soil bacteria to facilitate the conversion of organic matter into nutrients that a plant can use. Alternately, you can use a regular soil mix and then supplement your plants with liquid nutrients.

You can connect a controller to fans, dehumidifiers, humidifiers, heaters, or air conditioners, and set thresholds whereby each device will power on and off based on your ideal environmental settings. Some units run autonomously, making changes based on set parameters, while others allow you to control each element via an app on a phone, tablet, or computer.

Think of all the equipment in your grow space as organs in the body—if one fails, the others will have to work a lot harder for a bit, and then will fail in a matter of time.

Check for pests, mold, or nutrient deficiencies

For example, it takes less time to grow 3′ weed plants than 5′ plants; in the span of a year, you can maybe grow four harvests of 3′ plants, or two harvests of 5′ plants.

Too much humidity in your curing space and you might be left with perfectly grown, but moldy cannabis. Nobody wants that; neither the individual user nor the dispensary buyer. Moldy cannabis is easily the fastest way to ruin your reputation as a reliable grower of high-quality buds.

To start with, relative humidity is determined by how much water vapor the air can hold at a specific temperature. Warm air can hold more water than cold air, so the warmer the air is, the higher the relative humidity will be .

Here again is the equipment you can use to help you attain these levels:

Raising Temperatures

Whichever method you choose for trimming your product, suitable conditions for your drying room are important. You’ll want a cool, dark environment with temperatures in the range of 59-71°F and humidity at or near 50% . Yes, even after the growing process is completed, you still need to be concerned with temperature and humidity.

As you probably already know, after choosing a substrate (the material you’ll be growing your plants in/on), the strain(s) of cannabis you’ll be growing, lights, watering mechanisms and nutrients needed, the most important element of your day-to-day operation will be managing temperature and humidity.

Seedling Stage

Pure n Natural Systems specializes in the sale of commercial and industrial humidifiers, dehumidifiers, drying fans, air movers, and portable heating and cooling solutions. We have the equipment you need to make your growing operation a consistent success. And as we’ve already discussed, consistency is king.

On top of the need for specific temperature and humidity controls throughout the growing process, it’s worth mentioning that humidity level during the drying process is equally important to the quality of the final product.

For many growers, the cost of a commercial dehumidifier initially seems to be too high. However, ultimately, they are forced to pay eventually because of problems with humidity in their grow rooms.

One would imagine that purchasing a high-quality dehumidifier is near the top of a grower’s list of new equipment. In reality, however, too many individuals bizarrely go cheap and invariably end up paying twice. Does this sound like you?

Most novice growers have a handle on controlling a room’s temperature. Many may even know a thing or two about air circulation. However, novices often tend to struggle when it comes to maintaining the ideal relative humidity (RH) level in their grow room.

If this happens, your plants close the pores in their leaves to minimize water loss. It is an effective tactic, but it means they receive less CO2 from the environment. The result is cell death within your cannabis plants.

4 – Good Drainage

When you grow marijuana outdoors in a suitable climate, you don’t have to worry as much about the weather. However, the weather can still impact your crop, particularly if there is an unseasonable spell of weather.

Residential dehumidifiers are ineffective because they’re not designed to handle the level of moisture in a marijuana grow room. Also, they use a lot of energy and are incredibly inefficient.

Although humid air holds more water, it is lighter than the air that surrounds it. Therefore, it rises toward the ceiling of your grow room. Meanwhile, CO2, which is a critical component for plant growth, remains near the floor. As a consequence, your grow room must have excellent air circulation.

3 – The Importance of Air Movement

A common issue in the grow rooms of novices is the formation of standing water. As well as becoming a breeding ground for bacteria, this water releases moisture into the air. This serves to increase the humidity level of your grow room. Therefore, the room must have proper drainage to prevent stagnant water from forming puddles on the floor. If you use a hydroponics setup, make sure you cover water reservoirs to ensure the liquid stays where it belongs.

It is tempting to think that you can just water your plants more often in dry conditions. However, you will end up over-watering the soil and reduce the amount of air in the growing medium. Your plants will suffocate and become more likely to develop root rot.
