Wet Baled Hemp Drying

Taking hemp immediately from harvest to processor most likely means it was baled wet. While there are many benefits to working this way as a hemp farmer, your plants still eventually have to dry out for extraction. From wet to dry, here’s how to get the job done right.

/ WET BAILING HEMP

The Benefits of Wet Bailing Hemp

Leaving hemp out to dry in the field, after harvest, can create a lot of issues. Weather can impact the crop, especially if you live in an area with a lot of rain. Cannabinoid yield can also go down the longer hemp sits.

Wet baled hemp means you can harvest earlier and prep your crop faster for its transportation to a processing facility.

Preventing Issues

Leaving any organic matter wet, in the wrong environment, can lead to problems. For hemp biomass, that’s mold, and it’s bad enough to ruin a crop. If done correctly, wet, pressurized hemp bales are more resistant to mold since the oxygen gets taken out of the bale.

The only outside force you do have to worry about is too much heat. It won’t ruin the crop, but it can reduce the cannabinoid content of your plants.

Wet Baling Hemp

Wet-bailing hemp occurs in much the same way you’d wet-bale hay. You have the options of using large, long feed silage bags or putting the hemp into smaller, round bales. Once situated, all the oxygen gets vacuumed out. This prevents the hemp from rotting, fermenting, or degrading in any way.

The wrapping is key to protecting the bales. That, and storing the hemp out of the elements. If done right, bales can sit for 4-8 months before going through the extraction process.

Drying Wet Baled Hemp

Even though you’re harvesting and storing your hemp wet, before it hits extraction, it must get dried. Drying options are much the same with wet baled hemp as it is with hemp dried immediately after harvesting. You have two primary options — hang drying or using an industrialized hemp dryer. Both choices for hemp drying will effectively get the job done.

Hanging to Dry:

To effectively dry hemp by hanging it, you need a lot of space. Not only that, but the space needs temperature control and stable humidity. The conditions are everything when it comes to hanging hemp to dry, even hemp that was wet baled. When even one element is off, you risk degrading the quality of your hemp and its extracts.

To properly hang hemp to dry:

  • Make sure your plants have enough stem to tie them to the ceiling, If they don’t, you may need drying racks.
  • Remove unwanted leaves since they can restrict airflow to the center of your hemp.
  • Set the drying room’s temperature to stay consistently between 60-70 degrees Fahrenheit.
  • Maintain a humidity in your drying room of anywhere between 45-55%.
  • Use a room that’s well-ventilated, or add in a fan that can gently circulate air.


Drying can take anywhere from five days to a little over two weeks. It all depends on your plant’s genetics and the conditions in your drying room. Once complete, the next step in the process is curing. This allows the remaining moisture back into your hemp flower so it’s no longer crunchy and dry. Store your hemp in air-tight containers in a cool, dark, and dry room. Open the lids periodically to allow excess moisture out and fresh oxygen in. Curing can take an additional few weeks to complete the drying process.

Using a Drying Machine:

If you are looking to get your hemp dried in a hurry, you can opt for technology over time and use a hemp drying machine. Most of these machines are fully-automated and involve minimal human contact with your plants. They can get your crop dried in days rather than weeks, but make sure you’re working with an experienced processor to maintain the quality of your plants.
