We are not yet accepting applications to grow hemp outdoors for the 2020 growing season.
What is the process for becoming licensed to grow hemp in Maine?
- Apply for a license before April 1 of the year you wish to grow hemp.
- Departmental review and approval of application.
- Sign licensing agreement.
- Testing of crop prior to harvest.
Apply for a license
- The 2020 applications for indoor and outdoor hemp licenses will not be available until the proposed rules become final. The proposed rules are expected to become final in early February. License applications will be posted here when available.
Explanation of fees
Maine law requires that the Department cover the costs of operating the hemp program by charging an application fee, license fee and a per acre fee. These fees are as follows:
- $100 application fee – this fee must be submitted with the application.
- $500 license fee – this fee is due after approval of the application and must be submitted with the signed licensing agreement.
- $50/acre fee – this fee is due after approval of the application and must be submitted with the signed licensing agreement.
Fees collected will cover Departmental costs including, but not limited to:
- Inspector travel costs including time to and from the growing area to take crop samples for THC content analysis;
- Costs of transporting crop samples to a lab for THC content analysis;
- Laboratory fees for testing crop samples;
- Costs of equipment and supplies used in sampling;
- Departmental time reviewing applications, preparing licensing agreements and issuing licenses;
- Other administrative costs.
Please note that the fees charged will only cover THC testing for one composite sample taken to represent the entire licensed crop. Licensees that wish to have individual growing areas or varieties tested separately will be responsible for paying any additional laboratory costs.
Obtaining seed and seed certification
Availability of hemp seed is a major challenge to potential growers. While Maine law allows for the planting of hemp, and the 2018 Farm Bill removes hemp (any part of the plant, including the seeds thereof and all derivatives, extracts, cannabinoids, isomers, acids, salts, and salts of isomers, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis) from the controlled substances list, it remains unclear how the interstate and international movement of hemp seed will be regulated by the US Drug Enforcement Administration, US Department of Agriculture or other federal agencies.
Certified Seed Source
Maine law requires that hemp be planted using a certified seed source. The hemp rule (Chapter 274) defines a certified seed source as one that is certified according to AOSCA (Association of Seed Certifying Agencies) or other approved standards and comes from plants that were tested during the active growing season and found to produce hemp with 0.3% THC content or less.
The Department understands the very limited availability of hemp seed and the certified seed source requirements are difficult or nearly impossible to meet. While the Department is required to verify and collect documents which indicate the hemp seed planted comes from a certified seed source, for now, we can be somewhat flexible on the form this certification may take. Acceptable forms of certification could include a letter, form or other written verification or combination of these documents that at a minimum includes:
- Third party (someone other than the applicant and the grower of the seed) THC content testing results for the hemp. The third party should be identified on the testing results;
- THC content test results must be for the variety or varieties included on the application and preferably for the specific lot of seed to be planted;
- Results of THC content testing and the date tests were conducted;
- The name of the seed supplier and origin of the seed.
As hemp seed certified by AOSCA, or other official seed certification programs becomes more available, the Department will review and revise our policies and issue stricter guidelines for acceptable documentation of seed certification.
Sampling and Testing
The licensee will allow the inspection and sampling of the hemp crop at any and all times that the Department deems necessary. The licensee will be notified prior to inspection and sampling. During the inspection and sampling the licensee or authorized representative will allow complete and unrestricted access to all hemp plants within the licensed growing area(s).
If the hemp crop has not been inspected and sampled 15 days prior to the anticipated harvest date, the licensee will notify the Department of intent to harvest.
All hemp plants from all varieties and licensed growing areas will be tested for THC content as one composite sample. Licensees that request to have growing areas or varieties tested separately are responsible for paying laboratory analysis costs for any additional testing.
Crops testing above the allowable THC limit (0.3% THC on a dry weight basis) will be destroyed in a manner approved by the Department. The licensee is responsible for paying all costs associated with crop destruction.
Hemp or CBD in Consumable Products
The guidelines linked before are for use by DHHS and DACF retail inspection staff. They will be enforced beginning December 1, 2019. Please note that state and federal statutory changes and rulemaking are ongoing and may alter any of the conditions and/or add new conditions.

Frequently Asked Questions
I have a medical marijuana license. Can I grow hemp?
Yes, but hemp and medical marijuana plants cannot be co-mingled. The rule states: "No hemp plants shall be included in other licensed marijuana production programs. No growing area may contain Cannabis plants which the licensee knows or has reason to know are of a variety that will produce a plant that when tested will contain more than 0.3% THC on a dry weight basis."
What is a growing area?
A "Growing Area" is defined as the land (the current rules only allow growth of hemp "outdoors") on which a licensee cultivates or plans to cultivate hemp. A "Non-Contiguous Growing Area" is defined as a growing area on which a licensee grows or plans to grow hemp that is separated from other growing areas by more than 50 miles.
Can I include multiple growing areas on one license?
Growing areas that are within 50 miles of each other can be included on one license application.
When is a separate license required?
Growing areas that are "non-contiguous" must be included on a separate application. Each separate application requires submission of the full $100.00 application fee.
Can I grow hemp indoors or in a greenhouse?
- No. Growers can start plants indoors, but once the seedlings are hardy enough to survive outdoors they must be grown outside without any sort of roof or covering over the top.
- Hemp seedlings are defined as non-flowering plants that are no more than 12 inches tall.
- All seedlings started indoors must be moved outside and grown without coverings by June 30. Should the threat of frost occur after June 30, the use of a row cover or other frost protection is allowed.
- The Department is currently working on rules to allow hemp to be grown indoors and implementing a Hemp Indoor Growing Trial.
Can I grow hemp from tissue culture or clones?
Yes, as long as you can provide appropriate third party analysis on the variety you plan to grow. If you plan to grow from tissue culture or clones, submit documentation on the plants from which the tissue culture or clones will be produced that includes the same minimum information required above for those growing hemp from seed.
Indoor Hemp Growing Trial
Although Chapter 271: Rules for Growing Hemp (PDF) does not allow for growing hemp indoors, a new law opens the door to indoor hemp growing. While the department establishes new rules to support indoor hemp growing, 10 indoor hemp growing licenses will be issued as a trial. Ten applications will be randomly selected from the entire pool of completed applications received by July 31, 2019.
How do I apply for a license to grow hemp indoors?
Fill out the Hemp Indoor Growing Trial Application (PDF) and return it with the $100 application fee by July 31, 2019. Only complete applications that include all the required information, the fee and are received by July 31 will be eligible for a chance at the random selection process to receive one of the 10 trial licenses. The $100 license application fee is non-refundable, regardless of whether your application succesfully receives a license.
How will the Department select who gets a license?
Ten applicants will be randomly selected from the entire pool of complete applications received by July 31, 2019 to determine who gets a license. Only complete applications that include all the required information, the $100 application fee and are received by July 31 will be eligible for license selection.
What are the fees for participating in the indoor hemp growing trial?
- $100 non-refundable application fee. This fee is due at the time of application and is owed regardless of whether the application is selected for a license or not;
- $500 license fee. This fee is due after approval and selection of the application and must be submitted with the signed licensing agreement;
- R$0.10/square foot fee. This fee is due after approval and selection of the application and must be submitted with the signed licensing agreement;
- The name of the seed supplier and origin of the seed.
How long will the trial period last?
The Hemp Indoor Growing Trial will last until the Department writes and implements new rules supporting the indoor growing of hemp.
