Hemp Farming Harvest Checklist

Farmers of industrial hemp might be understandably eager to reap the rewards of their hard work during the growing season, but going straight to harvest is definitely ill-advised and could result in legal issues. Preharvest is one of the key steps in proving that your product is compliant. During the preharvest stage, there are a few crucial steps a farmer must take before they can enjoy this season’s bounty.

While specifics may vary, each state has similar regulations regarding the preharvest process. Because of the THC content requirements surrounding hemp, preharvest testing is fundamental in proving compliance and assuring a stress-free harvest.

Blue Forest Farms devised a general guide for industrial hemp growers in the United States, to help take the confusion out of the preharvest process. If you follow the steps below and make sure to look up your state’s specific legislation, it’s unlikely you will have issues.

Steps to Success

  1. Determine Your Harvest Lots and Dates

Know your harvest date! And if you’ve planted more than one field of industrial hemp, know which fields you are going to harvest when. You’ll need to enter this information on your Preharvest Report Form. The actual name of this form can vary by state but typically includes the words “preharvest” and “testing” in the name. Typically, the state Department of Agriculture requires that the form be submitted no more than 30 days before your projected harvest date, and that sampling be completed within 15 days of harvest. However, this timing may vary by state so we recommend visiting the Department of Agriculture website for the state where your hemp field is located.

  1. Fill Out Your Preharvest Report Form

This form must be completed before your product can be tested. As you might expect, it asks for your name, business name (if applicable), and contact information. Additionally, it also asks for your registration number. This is issued to you after you apply for a hemp grower’s license. If you don’t have one of these, well, I’m no lawyer, so I can’t give you advice there. This form will also ask information about your lots, like location and size, in addition to which strains you wish to sample. Often there’s a section to indicate the lab, which will perform the testing.

Here’s a sample of a typical form. Expect additional pages that explain each field that needs to be filled out. Make sure to strictly follow your state’s guidelines for filling out the Preharvest Report Form.

  1. Send in Your Form

Send your form to your state’s Department of Agriculture. If you need to figure out where to send these forms, the department’s contact information – phone, email, and mailing address – will be on their website.

  1. Samples!

The previous steps were an important preamble to the main preharvest requirement: taking samples of your growing hemp. This procedure can vary significantly by state, so make sure you completely understand what your state requires. Usually, once you send in your report, the Department of Agriculture will assign you a sampling date. Some will send a sampler to your fields, and some will expect you to send your sample to the lab by the date assigned. One important thing to note is the recent legislation changes regarding labs that are authorized to test hemp. During the 2021 hemp farming season, all laboratories testing hemp must be DEA approved and test for total THC, not just Δ9THC.

  1. Results

Once your samples have been processed by the lab, they will contact you with your results, commonly via email. If you’ve started with a strain with good genetics, and you’ve followed farming best practices, you should receive good news. But, anything that tests over .3% THC will have to be destroyed and anything testing at or above .5% could lead to legal penalties. Once you’ve received your compliant results, it’s time for the fun part – harvest!

Preharvest testing may seem like a daunting process but it is really just a matter of accurate timing and paperwork – fun! You can always use the paperwork as a chance to get off your feet… It is essential that you make sure to sample within 15 days of harvest, as CBD and THC levels continue to change with certain factors like sun and heat as the plants mature. After all your hard work, sit back, relax, and prepare for harvest.
