- Types of Trichomes Explained
Professor DeBacco
Trichomes
Trichomes- a small hair or other outgrowth from the epidermis of a plant, typically unicellular and glandular.
These structures are the site of cannabinoid, terpene and flavonoid production.
These are found on more than just cannabis plants as trepens function as a natural plant defense mechanism.
Glandular Trichomes
Glandular trichomes produce and store large amounts of cannabis resin which are found in high quantities on female flowers, but are also found on leaves and on stems of younger plants.
Glandular trichomes can occur as small bulbous trichomes with one-cell stalks, sessile glands which are attached directly by the base without a stalk, or multicellular stalked glandular trichomes with long multicellular stalks on the bracteoles surrounding the pistillate flowers.
However three a common glandular trichomes to cannabis…
Bulbous trichomes
Capitate sessile trichomes
Capitate-stalked trichomes
Bulbous Trichomes
Bulbous trichomes are found throughout the plant but do not produce or contain cannabinoid or terpenes
Very small at 15-30 microns in size.
Capitate Sessile Trichomes
Capitate-sessile trichomes that have a globular shaped head and are the most common as they are found on the stems, leaves and bracts.
While these trichomes do produce cannabinoids, the levels produced are much lower than the capitate-stalked trichomes discussed next;-)
These are mid-sized measuring from 25-100 microns across
Capitate-Stalked Trichomes
Capitate-stalked trichomes are the primary source of the cannabinoids, terpenes, and other plants oils found in the cannabis plant that develop only after flower formation.
If you look at the bracts of the flower and small tiny mushrooms that measure from 150-500 microns tall.
Non-Glandular Trichomes
Non-glandular trichomes are hair-like extensions resembling leaf hairs, with a slender pointed apex.
They protect the plant from its environment, mainly through physical means (e.g., restricting access to animals and insects, preventing water losses or light degradation, and fungal infection).
It is characteristic of cannabis to find non-glandular trichomes on both the top and bottom of leaves.
Two Main Non-Glandular Trichomes
Cystolithic trichomes
Non-cystolithic trichomes
Cystolithic Trichomes
Cystolithic trichomes have a characteristic bear claw shape and may have calcium cystoliths resembling knobs visible at their bases. They are found on the upper surface of the leaves and range from 150 to 220 microns in height. Frequently, the trichome is broken and the knob freed.
Non-Cystolithic Trichomes
Non-cystolithic trichomes are found most often on the lower side of the leaves, bracts, and bracteoles and tend to be fine and slender in shape.

22 year grower here. Found this video immensely informative. Keep up the solid work Professor.
Thanks for the comment and great to know you want to keep learning even after 22 years!
U never stop learning. This hobby evolves daily. Best hobby ever imo. 26 myself, feel like I just started.
@@randygreen6652 32 years old and i am just starting.. lol
I want to like this video more than once. This is the kind of information I’ve not seen on the Tube.
Looks like others agree with you, so tell others so they can also add additional "likes".
Unlike and like again
It’s course material/scientific study’s - not a UA-cam star trying to sell you the next brand
Watching your videos is like sitting through a legit college course, thank you for your hard work! It’s helps tremendously
Many of these videos are used in just that setting;-)
I appreciate this type of science based lesson. I usually turn off the stoners who try to explain something while they're smoking a joint.
True science based lessons are the goal of DeBacco University.
I think this is the first time I've seen a video that goes into such esoteric detail about cannabis trichomes
Great job and great info
Trying to provide quality cannabis education, so it sounds like mission accomplished!
I love you Prof D. Thank you for sharing with us!

Great video! Didnt know there were so many different kinds of tricomes! Super interesting and very informative stuff bro!!👊👍
Glad you found it interesting and thanks for adding your comment!
This video is great you know I'm a well experienced grower and even I had no idea that the tricome was actually a hair underneath it all this time huh 🤔 thanks.
Keep on learning!
This is brilliant. Love the way you explain the beauty of its biology from an analytical approach 😅
Thank you so much 😀

Sigo seu Canal aqui do Brasil carente de canais avançados, parabéns professor 🙏👏🇧🇷
Obrigado pelo seu comentário e fico feliz em saber que você está gostando do conteúdo do canal.
Thank you for sharing, do you know if there is any difference to be noticed by the trichomes of indica and sativa plants? Thnk you in advance!
Trichome development is independent of the strain being grown, in general as there may be some specific characteristics for specific varieties, but not distinctive indica vs sativa differences.
Love this, thank you. Do you know how these different trichomes effect the extraction rates of rosin? Even when lab tested for potency a lot of users find that some strains do not press as well as others. I'm just curious how the different trichomes come into play here. Thanks for this content 🙏
The trichome structure itself doesn't have the material we're looking to extract. We're looking to extract the material only from the inside of glandular trichome heads. There are many variables that contribute to how well a plant works for extraction including head size and thickness. Potency is not one of them however.
We just use screens n wait till flowers have fully dried n then separate the tricomes from the plant materials n then press just the tricomes n guess what you get the old afghani hash 😉
@@user-yr9qn6bk6o well said, thank you 🙏
Pressing extraction is not the most efficient which is probably what is contributing to the variable results.
Very good information and schooling , very interesting topic did not know there are different trichomes I 😎
Great to provide quality education!
Terrific video thank you. Besides colour, I advise looking at the position of the bulb on the stalked glandular trichs, drooping bulbs means they're heavy & super full of the good stuff and it's time to harvest. Peace to all.
Thanks for your additional advise.
thank you 👍
You are welcome!
I nibbled on a leaf today and swallowed it is very rough going down you're illustrations explain why it was the bear claws sinking into my esophagus. I love your info thank you it was getting close to harvest time for me
If only you had watched the video before you had gotten hungry....
Awesome T y. Very good just became legal in my state and I'm gonna be growing.
Best of luck!
I always thought Sessile pronounced sess-asile, awesome video and great content! Thank you 🙏
Glad you like the content provided!
Fascinating & well explained. I once saw flower buds that had small pools of resin , as if the trichomes had all collected together.
The strain was Purple Trainwreck , 14weeks flower. 🐱
Interesting morphological observation.
Look up cannabis guttation
@@northwoodshaman isnt that when the leaves or buds secrete excess sugar stored in the plant??? There was a video I watched about it but couldn't remember if that's what it was called exactly but sounds right..🤷♂️
If you don't know, now you know!" 💚🌱👌💨
Goal of education!
I stay Gucci down to my socks. .
Can you please tell what are those trichomes which are found above the covering of seed when plant is in flowering, I'm not talking about trichomes on seed itself but on seed's covering
Does not sound like you are describing trichomes.
Does anyone know if there are any informative videos in a similar vain as this one regarding trichomes on other plants, specifically on leaves? like oak leaves?
You can look at Tobacco as well, but the contents will be different.
Great to know. I thought the capitate sess had broken tips....thx
You are welcome!
last year was my first time growing and it was outside, about half of my trichomes lost the bulb on the end, just the stalk was left and they were not hair trichomes, why would this happen? It is extremely windy where I live but I dont think that would be the cause would it?
Sounds like some form of physical damage.
Hi Professor
Question my gorilla glue auto trichomes are still clear have low aroma , small buds about two weeks left . When should I do 48 hr of dark ?
Thank you
48hr before bud removal from the plant.
Can you explain the Cannabis from the '80s that we grew had calyxes full of resin. Back then we thought this is where the THC come from. You did not see the trichomes on the plants back in the '80s but we still had some really strong weed that would put you in your seat after two tokes. Today's weed is completely different. We haven't seen anything like that in these newer strains including the potency. It would be really awesome if you could make us a new video strictly on this. We had buds that were dripping with resin literally on certain strains and I'm sure it had a lot to do with how we grew it.
An image of the structure would be helpful but this does not sound possible. Through selective breeding this could be brought back (ideally at least).
Are Cystolithic hairs different from Cystolithic trichomes? As at 6:03 in the righthand photo, the stalked glandular trichome has a darker interior, appearing like a dark Non-glandular, but dark orange/brown. I haven’t heard of a cystolithic trichome before only cystolithic hairs, which dont have anything to do with trichomes as far as i’m aware?
The Cystolithic trichomes have a hair like appearance.
,,,,I have been formerly schooled here.......finnaly!!!...thank you .........moving onto scientist level😯😯
Nice to see you moving on up!
The knowledge that you pocess about the devil's lettuce is impressive.
Thanks for the comment, you must be an upper tier grower;-)
Love it . to 😎.
Thanks!
Do they get knocked off if the plant gets rained on?
Some damage may occur, but not removed entirely from the plant due to rain.
Sir, do you have any resources you recommend (books/classes)
This channel has many informational videos, but also the Universities mentioned at the end of this video... ua-cam.com/video/yggnAlJt0y8/v-deo.html
I tried something different this year. Beginning in September, I grew under a light 24/7 for 6 weeks and 4ft tall. Went outside to natural lighting and transplanted into 15 gallon fabric pot. Immediately went into flower. It's been 3-1/2 months now and grown another foot in the process. Buds are nice and thick but there is no smell. Maybe a hint of cut grass if anything. Should have another month before harvest. Any ideas why no smell? Thanks
No smell likely means no terpenes have had a chance to be produced by the plant. These typically increase in the later stages of plant growth.
What is your opinion about autoflower plants? Mine are full of buds and will reach maturity in about 2-3 weeks, however, the plants are very small (less than 2.5').
Autoflowers, great for small spaces and known harvest times, but still need some further breeding to improve end product.
@@DeBaccoUniversity As always, I appreciate your response! Can you tell me what trimming scissors you use - curved or straight? Want to order them from Amazon. Thank you. Do you trim immediately after cutting or when the plants are dry?
is their somewhere i can find a clearer version of the clip as its hard to see the pictures
Might try his actual website
@@robertthegrowguy7115 all good was my stuff up had the settings on 460 p
@@robertthegrowguy7115 was my stuff up was set on 460 p thanks for the reply
Turn your setting up to 4k as this is the quality level the videos are recorded in. Also the description has links to all content including image links.
@@DeBaccoUniversity ok thanks
Ok, dude you're not really giving any additional information that isn't on the slide. at 3:23 you said that they measure from 15-100 but on the slide it says 25-100. So which one is right?
In formation provided is off the slide for the hearing impaired so it shows up on the subtitles for easy understanding. The range of 25-100 would be more accurate.
sharing this because more people need to learn that there are more then 1 trichome
Thanks for sharing this, hope they also subscribe to the channel!
Is it possible for specific terpenes or cannabinoids be produced in some types of trichomes but not others on the same plant?
In short yes, in an extreme case consider the trichomes of a tomato plant compared to a cannabis plant. But even on the same plant there can be great variability.
@@DeBaccoUniversity I've posted a comment just a moment ago separate to this, but my wedding cake, one of the photos that showed non glandular trichomes at about week 2 veg, smelt just like a tomato plants green part, and I hate that smell lol, now I'm about week 2-2.5 of flower and they picked up a more liquorice smell, or like wine gum smell, does that have to do with being glandular or or non glandular?
@@DeBaccoUniversity also I have a male that has such gassy terps, and was wondering if I cross it, is there a good chance those terps would transfer over? Is there any way to tell which plant would have the dominant genes going into said offspring?
Do the non-cystolithic trichromes produce and thc or terps?
These are more for environmental protection for the plant and do not produce much in the way of terps or cannabinoids.
ive always wondered about those tiny little trichomes, also i didnt know those things people refer to as cystolith hairs are considered trichomes
Glad to provide quality content!
What about trichomes that remain cloudy or clear beyond maturity of plant? I know 70/30 70% cloudy 30% amber... but what do you do when they are 90/10 and autoflower is at max weeks
Some do not "follow the rules" ;-)
do non-cystolithic trichomes have the same amount of thc?
In short... no.
Thought i knew, then I watched. Ha ha ha ha THANK YOU
Glad to help continue your education;-)
Found this. Too high to watch it. Liking it for later. :)
Self awareness is important.
I have a few questions. if the capitate- stalk trichomes ( the high light or the one most grows seek for) are 150-500 microns but why with ice water hash the 45- 73-90 micron is considered smokable hash and the 120 -160-190 microns are food grade? and how come you never sift for and higher than 220um? If the best trichomes are 150-500um?
Would love to see a video on the trichomes in different microns of ice water hash and cannabinoid that develop In ice water hash compared to it live or dried material. some say that it completely changes some of the cannabinoids in the process making it different or new cannabinoid that are not found on it live or dry starting material.
The larger sizes are taking into account the stalk and not just the top bulb region which is probably the reason for the confusion.
Noticed my young plants and seedlings growing non glandular trichomes on the fan leaves, and first leaves, I do have the light really close in their seedling stage, about 10inches, but am only using cheap Chinese blurple leds, and only have it running at half power currently, do you think the lights being close would be the reason? I'm growing the seedlings in cheap potting mix, and the younger veg stage plants in peatmoss believe it or not, and my plants seem to like it, I just treat it like I would coco and have had decent results, also have noticed my autoflowers will never give me trichomes until week 2 or so of flower, while the photos so far have been all giving me a lovely peek into their terp profiles. I assume the lights were too intense so it popped some trichomes as a defense mechanism, but I have no degree lol tell me what you think. Thanks.
Improve the lighting would be a good start.
@@DeBaccoUniversity would you say it's a negative stress event? Should I try to avoid it if possible?
What about red colored tricome?
This could be an old amber-like trichome and/or related to a stress response.
so the crystolithic thricomes are the ones that have been stinging me every time i work on my plants
This is very likely.
The best weed always has short fat trichs. The ones with the long stems can be deceiving and look more abundant then actually are. And I don't mean the completely stalkless trichs. Just the fatter bulbs.
Visual inspection is the important part of the process.
🙏
Thanks.
👍🏼
Thanks!

No words just an emoji;-)
1:52 just one note here. Micron/micrometer is um, not uM. The latter is microMolar.
The image is sourced in the description, but thanks for pointing this out.
@@DeBaccoUniversity I figured you knew already but assumed it was likely a typo. Thanks for confirming.
Out of curiosity I ate a flower plucked fresh, all of those little pointy hairs feel like spikes when you eat it.
Remember cannabinoids need to go through a decarboxylation step that involves heat.
Is this a University anyone can apply to?🤗
Currently the video lectures are used in various Universities and schools.
@@DeBaccoUniversity Thank you , that's great to know. An Open University type online course would be popular.

@@DeBaccoUniversity There will always be haters, but you do great work. Thank you.
No wonder i get high smoking stems...lol just kidding but seriously tho, if you're looking for a nice ice and low heat waterbased extraction butter, stems and upper branches can be very beneficial to add, assuming you haven't used any sort of pesticides fungicides or herbacides in those areas of the plant stalk.
Thanks for your contribution.
Does anyone have experience with NO trichomes? My plants are large and beautiful and close to harvest, but no smell, very few visible trichomes.
No trichomes means no terpens or cannabinoids (or at least minimal amounts).
@@DeBaccoUniversity thank you so much. I’ve never had this happen. Past few months down the drain. They are so beautiful, too. 🥺
Could I ask why this may happen?
@@patticriss2238 Tom's wife Pam here, bringing about 50 yrs experience to try to understand what happened to this plant. IK I'm a bit late to this "party" but if you can, I need to know what medium you grew in, your light and seed source, and also what the plant was fed.

Can someone please let Tommy Chong know... Hashish isn't made out of pollen. Lmfao.
Lmaoo, yeah I get that. A lot of older people and misinformed refer to trichromes or once it’s fallen “kief” as pollen for some reason. I’d hate to smoke some pollen haha
Not pollen, pollom. Sifted using screens, borrowed from the wheat flour industry. So 04, 03, 02, 01, 00, and the best, prem short for premium. Which is the trichome heads, sifted and pressed.
@@plebpunkWell, I didn't know that. I have read a few books about hashish, and don't ever remember that term. Thanks.

Stop touching flowers too. It’ll damage them and false positive too for new growers.
Not sure where in the video the flowers are touched, the key is visual inspections.
@@DeBaccoUniversity didn’t say u touched the flowers. People always try to grab buds and touch them.

Don't mention hemp around the Marijuana community. They won't talk to ya anymore.
Don’t mention marijuana around the CANNABIS community...... they may not talk to you anymore.
@@stevehillbilly5797 Agreed!
@@stevehillbilly5797 well I just noticed whenever I mention hemp,I get a cold shoulder. I prefer and grow hemp.
@@stevehillbilly5797 aint CANNABIS both
It’s Cannabis Community lol. People need to stop calling it Marijuana. It’s a derogatory term from prohibition years ago when Mexico started flooding the market with brick weed.
This taught absolutely nothing..lol It's like.."This is cannabis, it has leaves on it, the leaves can change color"...oh wow :o
The teaching is in the video and it centers around trichomes not leaves, however the learning is the responsibility of the viewer.
You didn't explain the difference in chemistry and effects the types of trichomes would have and for that im disappointed in this video.
As stated this videos goal was to explain the different trichomes based on physical structure. The chemistry and effects are a different category, not related to the physical structure of the trichomes.
awesome after all these years of searching its all here in your shares...technical and modern but applicable to any one who grows nice2know/manythxs
Thanks for the positive comment!
