Twister T4 Trimming FAQS
Last Updated: August 22, 2025
Do automated trimmers like the Twister T4 really damage buds or knock off trichomes?
The Twister T4 is engineered to minimize trichome loss using its SoftTumble technology, precise, food-safe nitrided blades, and the Twister proven process. The design prioritizes gentle handling and a fast process (about 20–30 seconds per batch), reducing the time buds are exposed to friction compared to other machines or prolonged hand trimming. Proper adjustment and operation are key to preserving trichome integrity.
Will the T4 “eat” my weed or cause excessive product loss?
When used correctly, the T4 does not “eat” your buds. Its micro-adjustable blade technology allows you to fine-tune the cut height for minimal loss. However, if blades are dull or the machine is not cleaned regularly, you may see more trim or smaller buds passing through. Routine maintenance and proper setup prevent excessive product loss.
How does the tumbling action affect bud structure and density?
The T4’s gentle tumbling action is designed to maintain bud structure and density. The process is quick (typically 20–30 seconds per batch), so there’s minimal opportunity for buds to be beaten up or flattened. Overloading or running the machine too long can cause damage, so following recommended batch sizes and timing (including proper incline) is important.
Can the Twister T4 handle large, sticky, or dense buds without jamming or clogging?
Yes, the T4 is built for commercial throughput and can handle dense, sticky buds. However, sticky resin can build up on blades and tumblers, especially in warm environments. It’s crucial to trim in a controlled environment similar to a dry room (around 60–65°F and 50–60% relative humidity). Regular cleaning and periodic adjustment ensure correct operation. When trimming wet, operators can apply cold water to the machine brush with a spray bottle every few minutes to reduce plant material build-up.
How much trim do I lose compared to hand trimming?
The T4 is designed to maximize yield and minimize trim loss. With precise adjustment, you can achieve a trim quality close to hand trimming, but some very small pea-sized buds or loose material may end up in the trim, as with any machine. Many growers find the trim loss is comparable or even less than with hand crews, especially after dialing in the machine.
Does the T4 flatten, bruise, or otherwise beat up my buds?
When operated as intended and with proper preparation, the T4 preserves bud shape and structure. Its quick cycle and gentle tumbling minimize bruising and flattening. Overfilling the tumbler or running batches too long can increase the risk of damage, so follow recommended procedures for best results.
How do I prevent popcorn buds or small nugs from getting sucked into the vacuum?
Using the adjustable vacuum and feed rate controls helps reduce the risk of small buds being sucked away. Some loss of very small pea-sized buds is possible, but careful adjustment and monitoring during operation can minimize this issue. The optional narrow slot tumbler is also capable of preventing smaller flower from being pulled in to the blades
Can I adjust the trimming tightness to avoid over-trimming or under-trimming?
Yes, the T4 features micro-adjustable blade technology for ultra-precise blade adjustments, allowing you to control how tight or loose the trim is. This lets you tailor the cut to different strains and preferences.
How do I dial in the T4 for different strains or moisture levels?
Adjust the blade height, machine incline, and feed rate according to the bud size, density, and moisture content. For stickier or wetter buds, slower feed rates and more frequent cleaning may be needed. The T4 is designed for both wet and dry trimming, with separate tumblers with different slot widths to match your style of trim.
How much labor does the T4 actually save compared to a hand crew?
The T4 can replace a large hand crew, processing up to 23 lbs wet or 7 lbs dry per hour with one machine, and even more in tandem setups. This dramatically reduces labor costs and time spent on post-harvest processing.
What’s the real throughput per hour for wet vs. dry trimming?
Expect up to 23 lbs per hour for wet trimming and 7 lbs per hour for dry trimming with a single T4. Tandem setups can double or triple this output. Actual results may vary based on strain and operator experience.

- Use cold water spray on brushes when trimming wet flower
- Use tandem machines and conveyors to maximize throughput.
What is the ideal moisture content and water activity when using a trimming machine?
Optimal moisture content is about 11-13% with relative humidity around 60%. This balances ease of trimming with preserving bud structure and minimizing stickiness that causes buildup. Wet trimming is done at higher moisture (~30-35%) but requires more frequent cleaning.
How much flower is lost in the trimming process?
The amount of flower (not trim) that is trimmed inadvertently with an automated trimmer is highly dependent on the preparation process, the machine or combination of machines being used and the cultivar being processed. Twister machines are typically 1-10% flower trimmed off compared to a very detailed slow hand process. Truth be known, hand trimmers are often in a rush to get through a batch as they are paid by the weight hand trimmed so the results from a perfect trim can be much closer yield to the machine trimmed flower. When the lost flower is compared to the sheer labor savings of well dialed in automated trimming line, the financial gain far outweighs the yield disparity.
Does machine trimming damage buds?
When properly operated using the Twister Proven Process, Twister machines do not damage buds. Their gentle tumbling and precise cutting preserve structure and trichomes. Overloading or incorrect settings can cause damage.
How to use a machine trimmer without damaging the buds?

How does machine trimming impact terpenes?
Minimal impact when trimming is done quickly and at proper moisture. Reduced handling time preserves terpene profiles better than prolonged hand trimming.
What strains or genetics does machine trimming work best with?
Strains with moderate density and moisture content trim well. Very sticky or extremely dense strains require slower speeds and more cleaning but are still compatible.
What strains or genetics does machine trimming not work best with?
Extremely delicate, fluffy, or overly sticky strains may require hand trimming or special machine settings. Very dry or brittle flower can also be challenging6
How can you tell the difference between machine trimming and hand trimming?
Machine trim is very consistent and uniform, sometimes slightly tighter than hand trim. Hand trim may have more variability but can preserve delicate structures better on top colas.
What does the cutting blade look like? What does the cutting?
The cutting is done by the hardened nitrided steel blades mounted on a rotating reel inside the tumbler. The tumbler gently agitates buds while blades shear off leaves precisely6.
How often do I need to replace the blades or the bearings?
Blades last up to 600 hours with proper maintenance. Bearings and other parts have long lifespans but should be inspected regularly and replaced as needed.
Can I just run the trimmer and not the vacuum?
Vacuum is recommended to collect trim and prevent mess. Running without vacuum is possible but not ideal and may increase cleanup time and product loss.
What should my room environment be when I’m trimming? Does this play a factor when wet/dry trimming on the T4?
Ideal room temperature is 60-65°F with 50-60% relative humidity. This environment minimizes stickiness and preserves bud quality. Wet trimming requires more frequent cleaning and moisture management.
