Industrial Hemp Drying Guide: How to Dry Hemp

MediaMary Uncategorized

This industrial hemp buying guide helps farmers learn how to dry hemp. Drying hemp is a crucial step that many people overlook. No matter the quality of your harvest, without the proper drying practices, it’s easy to turn an incredible crop into a mediocre one. Since the 2018 Farm Bill was passed, many farmers have been expanding their operations to include hemp crops. Our Denver hemp company is here to assist you through the transition. This guide covers how to dry industrial hemp:

How long does hemp take to dry?

Are you wondering how long hemp takes to dry? This is a common question among the farming community. The standard for drying hemp ranges between 3 to 5 days and 7 to 10 days, depending on your growing conditions. Humidity can play a part in extending the drying process along with other conditions that may be unique to your microclimate. Drying your hemp in a clean drying room and facility is critical. This industrial hemp drying guide explains how to dry hemp following best practices.

How do you know when hemp is ready to harvest? 

Before you begin drying your industrial hemp, it is important to be sure it’s ready for harvest. To an untrained eye, knowing when to harvest hemp can be a difficult task. We encourage farmers to monitor and test their crops on a week by week basis to ensure they are not only growing healthy and robust hemp plant but a compliant one as well. Since many strains require different attention, you must familiarize yourself with the specific needs of your current crop.

Compliant hemp means hemp testing under .3 of total THC. To get the total THC of your crop, you use this formula: THCa x .877 + THC = Total THC. If you are approaching the .3 marker, then we recommend harvesting your crop no matter how many weeks it’s been growing for. If your levels are low, then you need to start examining the trichomes of the hemp plant. The trichomes are the little white hairs on the cannabis plant. The deeper and more vibrant the color of the white hairs get, the more likely it’s ready for harvest.

Having a timely harvest is very important to the value of your hemp. If you end up having mildews or molds, it would be degrading the potency of your crop, and that will lower the price immensely.

Industrial Hemp Drying Methods

Industrial hemp drying comes in many different forms. If you’re wondering how to dry hemp, the answer may rely on the tools and resources available to you.

Hang Dry

As soon as you are done harvesting your hemp plants, you should transfer them to the drying facility so they are no longer in the sunlight. When they arrive at the facility, you’ll want to hang your plants individually upside down on a drying wire, and depending on how big they are, you may need to hang each branch individually.

The more ventilation in the facility, the better your crop will turn out. Set up numerous fans and keep them blowing non-stop to help keep your facility between the 60 to 70-degree mark. The building needs to be able to stop the elements from coming in, like humidity and other variables that can end up hurting the crop in the long run. The more controlled environment you can create, the more profits your farm can make.

Something to be aware of is while the plants hang upside down, the branches may clump together and not allow very much airflow. If this happens, you will need to implement the individual branch method I mentioned before. This can seem like a lot more work, but it will save the total plant from building up too much moisture and mold on the inside. The lower your levels of moisture, the better. If you can stay around the 8% mark or as high as the 10% mark, then you should feel secure in knowing your plants are dry. If your hemp is testing higher than that, then you should continue to dry and cure your crop.

Hemp Dryers

The Hemp dry method may give your crop protection from all the outside elements that would normally affect the plants while hanging up drying. It will help with the stabilization of your hemp crop as well. This kind of method is preferred when you are growing a large amount of hemp and especially when you’re just growing for biomass. The newer machines have a lower temperature that doesn’t take an abundance of your cannabinoid profile away. You won’t have nearly as much labor when using a hemp dryer, and it means you won’t to have to use the hanging methodology. There are some reported hemp dryers that can run a batch in under three minutes. Once hemp has entered into the drying structure, it won’t stop moving until it has entered the machine. There have been reported complaints about hemp dryers regarding damage to plants, but the pros can outweigh the cons when you think about being able to sell to consumers earlier. The theory behind the hemp dryers is to have a higher-grade product that can sell to consumers sooner as long as it doesn’t accumulate too much damage in the dryer.  (I’m not quite sure what you’re trying to say here)

Hand Harvesting/Biomass Harvesting

The more you do by hand when it comes to harvesting and drying your plants, the higher your test results will be for terpenes and cannabinoid profiles. This is a similar method to hemp’s cannabis brother marijuana. This route is not for the faint of heart because it is much more labor-intensive and ends up being more costly at first. This method becomes more difficult when you have to increase your hemp operations. on the larger your crop, the more likely you will need a hemp dryer. Whole plant extraction consists of harvesting biomass and rolling them up like you would see on wheat straw farms. Depending on your size, it might make sense to do a little bit of both. If you had cut the tops off of the plant because the tops will have the majority of the sellable product and use the rest for biomass production. 


Tobacco similarities and differences

Industrial hemp drying isn’t much different than the process used with tobacco crops. Drying hemp has both similarities and differences in drying tobacco, depending on what you are growing it for. A lot of farmers are using tobacco barns for the drying process of all types of hemp. To understand both products, you need to know that there are two standard types of drying tobacco: air-cured and flue-cured. Curing is a more in-depth prosses of drying and aging the plants in a dark air-filled environment. 

The air-cured process of drying tobacco is the closest to drying hemp as a whole. It is most like the hang-drying process of hemp to be more specific. Both are kept in a well-insulated environment and hanging for weeks at a time. Tobacco can take 4 to 8 weeks to dry and cure with this process and is generally used for high nicotine production. Whereas hemp should only take a month if done correctly and will have a higher cannabinoid and terpene spectrum. This long-term process would be better for growing hemp for high CBD and CBG production and producing for flower.

The Flue-Cured process for drying tobacco is the least like drying hemp, but it would be the most similar to using a hemp dryer. Both are shorter time frames than their predecessor. Flue-cured can take a week or less, whereas using a hemp dryer can take under a day. Flue-cured is a process exposing the tobacco to smoke and fire and slowly increasing the temperature throughout the week. The temperature reached is far higher and greater than anything hemp will be exposed to in the hemp dryers. The flue-cure is generally used for cigarette production. This process would be the best for hemp biomass.
