Dry Trimming SOP

1. Ez Trim was started because we had the same concerns as most growers regarding harvest automation and quality
2. We have spent the last 10 years developing wet and dry systems that will allow you to automate the harvesting process without sacrificing quality
3. The systems and equipment are only half the battle, the challenge is staying disciplined when following the systems over time



  • Remove the large fan leaves from the stem
  • 1 – 3 People required
  1. Defan during the flushing period and prior to harvesting
  2. Remove all fan leaves that have exposed stem
  3. The most efficient way to defan is by hand and by quickly pulling the leaves down towards the base of the plant, scissors can also be used for this step
  4. Focus on the leaves that have stem exposed, especially at the base of the flower to prevent crow’s feet from occurring after trimming
  5. You can also defan prior to or while debudding
  6. The debudder will assist in separating fan leaves from the stem
  7. You will have to sort the leaves out by hand or run them in the trimmer along with the buds, which can contaminate the quality of your trim with chlorophyll and extra plant matter
  8. We highly recommend removing the fan leaves before drying the plants, as once the leaves dry, curl and shrink, defanning becomes difficult
  9. The fan leaves if not removed before drying will create stems that will need to be removed post trimming which requires you to handle more flowers after trimming

STEP 2. –  HANG DRYING to 55%

  • Dry the whole plant or individual stems by hanging them upside down
  • 1 – Person Required
    1. Hang dry the whole plant or individual stems and ensure you have proper airflow, ambient temperature and humidity level in that room
    2. We recommend drying as slowly as possible at 60% humidity and 60-70 degrees Fahrenheit for at least 4-7 days
    3. Circulate the air, pull in fresh air periodically, and check the product daily
    4. If shucking with our debudder or any automated shucker, DO NOT DRY THE PRODUCT COMPLETELY
    5. Over-drying the flowers at this point will cause the flowers to occasionally break apart when either shucking or trimming
    6. Hang drying is complete when the ambient Humidity reaches 55%
    7. At this point, the stems should bend to 90 degrees before snapping, the outside of the flowers should be slightly crispy and the inside of the flowers should be fairly moist and spongy


  • Removing the flowers from the stem
  • 1 – 2 People Required per machine
    1. Properly prep the product by removing all fan leaves and individualizing the stems from the stock
    2. Be sure to leave 1-2” at the base of the stem,  so that the rollers have something to grab onto
    3. Individualizing stems from the branches prior to debudding minimizes the potential for damage
    4. The amount of individualizing required will vary strain to strain
    5. The Debudder should be run at slower speeds, around 15-20 on the speed dial
    6. Take the time on this step to ensure the flowers are 100% properly prepped for trimming
    7. If using our Debudders, feed the individualized stems into the Debudder
    8. We recommend utilizing 1-3 people per Debudder at this step, with 1 person individualizing the stems from the stock and 2 people feeding the stems into the machine
    9. The Debudders will quickly and gently remove the flowers from the stem utilizing rollers that grab the stem and pull the stem through various hole sizes
    10. If not using an automated shucker, using scissors, cut each flower from the stem at its base
    11. It is crucial to ensure that the buds are individualized and ready for the trimmer after this step
    12. This includes making sure that there is no more than an 1/8” of stem at the base of the flower, all fan leaves have been removed and that there are no clusters of buds on a single stem


  • Quickly dry the outer leaves for trimming while leaving the inner flower spongy
  • 1 – person
    1. Leaf Crisping means that you introduce ample amounts of airflow over the outside of the flowers to crisp up the outer leaves quickly, while the inner flowers remain spongy
    2. Leaf Crisping allows the trimmer to trim the outer leaves very quickly, while maintaining the structure of the flower, and because the inside of the flower is still spongy and not over dried, we can avoid any excess break down that trimming can cause
    3. When using the Leaf Crisper, place the partially dried shucked flowers into the container and turn the inline fan on to its highest setting
    4. The air is pulled up from the bottom of the container where the moisture settles and around the flowers at a very high CFM
    5. Program the timer to run the Leaf Crisper anywhere from 30 minutes to 2 hours depending on strain and moisture level
    6. The goal is to dry the outer leaves as quickly as possible, without over drying the inside of the flowers
    7. The product is ready for trimming when the outer leaves snap when agitated, but the flower is still nice and spongy (leaf Crisping isn’t always necessary before trimming)
    8. Leaf Crisping decreases the risk of trimming over dried flowers and the breakdown that can occur
    9. If not using our Leaf Crisper, supply the flowers with ample amounts of direct airflow for 30 minutes up to 3 hours using fans
    10. Check on the flowers, mix and rotate every 30 minutes
    11. The leaves are ready for trimming when they snap when agitated and do not bend
    12. The objective is to dry the leaves quickly, so they snap while still maintaining sponginess to the inside of the flower


  • Trim the exposed leaves from the flowers
  • 1 – Person required per machine
    1. Use the dry trimming grate, run the main motor on low, the lid motor on forward and medium speed
    2. Ensure the product is dry enough for trimming (leaves should snap when disturbed
    3. If dried properly the outer leaves will be very dry and crisp and the center of the flower will still be a little spongy, this is crucial for maintaining the original structure of the flower
    4. If the product isn’t trimmed in under a minute, the product is too wet
    5. Short cycle times are crucial, if the product has been dried properly you should be able to trim 300 – 500 grams in under minute
    6. If using the Ez Trimmer, place 300-500 grams of product into the machine
    7. Allow the product to trim for 30 – 60 seconds depending on the strain
    8. Adjust the airflow and rotor speed to optimize the internal flow rate and trim cycle time
    9. Be sure to utilize the dry trimming grate, if the product is still too moist to trim, try trimming using the wet trim grate
    10. Proper preparation is key to quality trimming, individualize all flowers, remove all fan leaves and keep no more than an 1/8” to 1/4 “of stem at the base of the flowers
    11. Different strains require different adjustments to the machine while trimming
    12. There is a balance of quality and speed for every strain, some strains require zero touch up, while others need some, find the optimal trimming cycle time and touch up required that creates the best quality and efficiency
    13. One person can efficiently run up to two trimmers
    14. If you must track your trim by strain, we recommend having extra filtration bag sets for a quick swap out between strains
    15. For clients that prefer hand trimming and hang drying or smaller operations that don’t need the capacity of the Ez Trimmer, we offer the Wander Trimmer for fast and efficient trimming of your wet product, and the Nanosat for trimming your dried product
    16. If hand trimming with scissors, you know what to do… Good Luck

Ez Trimmer – Operating Instructions


  • Sort the Flowers into different sizes for drying and packaging
  • 1 – 3 People required per Sorter
    1. The Sorter lets you accurately, efficiently, and safely sort your buds into shake, popcorn, small, medium, and large buds
    2. Without vibration or moving parts, your buds stay in pristine condition
    3. The buds are sorted by brushing the product down various sized sorting grates and into their appropriate container
    4. The Sorter is typically used as a quality control station
    5. As the buds come out of the trimmer they are loaded onto the sorter for a quick inspection and any necessary touch-up
    6. Quality control, or touch up, should be happening simultaneously to trimming and with the proper team should not be a bottleneck in the process
    7. To avoid a bottleneck, increase the number of employees on quality control if necessary
    8. The Sorter is intended to be utilized post trimming, when trimming dry, and pre-drying, when trimming wet
    9. The Sorter will increase your efficiency when packaging by separating similar weighted flowers, and increase consistency for drying, by separating similar sized flowers
    10. Sorting will create a consistent price per pound for your various sizes of flower


  • Store and burp the flowers to create great taste and smell
  • 1 – Person
    1. Place properly dried and trimmed product into appropriate sealed containers
    2. Curing is not something easily scalable, ratios of air to product is crucial for oxidization and absorption of terpenes
    3. Regardless of the container you use, or room size, the ratio of product to air space should be roughly 75% product, to 25% air
    4. Aerate, or burp, the containers daily by opening the sealed containers every 12 to 24 hours for 5 -10 minutes
    5. Be sure to rotate, or mix the product every 24 hours
    6. Ideal container humidity should start at roughly 50-60% and taper down to 30 – 40% over the curing process
    7. Cure for no less than 5 days
    8. Inspect the product daily, ensure proper moisture level through touch, and cure completion through smell
