Last year I started some satiiva seeds from 1984 that had been in my freezer in a plastic bottle and most germinated, and about 25% became viable seedlings
great video, thanks for sharing i keep my seeds stored in a jar at the bottom of my refrigerator at 5C and lower with desiccant packs to keep moisture levels low. i worried the desiccant packs may have overdried the seeds however i've had 100% germination using this method and this video backs up that confidence in my storage method so thankyou very much i have heard of seeds being stored in freezers for two decades and having been viable still it's very useful to have some science to back up these claims long term storage of cannabis seeds is critical as we are seeing a lot of irresponsible breeding and bottle necking of the genetics which will only exacerbate over time as the demand for fem seeds goes up now is the time to really protect current and old world genetics, with a view of regular reproduction to keep seeds viable.
Freezing makes the most sense. You have to think, these seeds in nature fall off the plant, get covered by leaves, freeze, and germinate when it warms back up. People try to over complicate things. Just do what Mother Nature does and you’ll be good. There’s a reason that the largest seed bank in the world is in the arctic circle.
@@DeBaccoUniversity aka a desk, a barn, a fridge, a freezer, what type of bag or jar, what material absorbs better vs worse. You said temperatures and percentages. How is grandma supposed to know the temperature of her fridge or how is the 18 year-old supposed to know the humidity of his closet come on man
@@DeBaccoUniversity the title is how to store cannabis seeds. You don’t tell us how or where to store them. you just tell what temperature and what humidity is optimal to store by science. not actually how to maintain them in a real world situation, at that scientific temperature and humidity.
Looks like a thermometer and a hygrometer (these often come together in the same unit) is in your future. There is no way to know the temperature of your desk, barn,... so collect some data and match it up to the study.
If you store in the little seed vials is it necessary to put small pieces of silica gel in with the seeds?or should you just put a silica pack in a large container that holds all of your seed vials?
Absolutely I have had seeds for over 4 years in a film canister in my sock drawer (with central air) and I still had about a 70% germination rate (7 out of 10 with one male) so don't over think it and never throw away seeds because you won't know unless you try.
I managed to germ approximately 8 year old seeds that were stored in a plastic meds bottle, in a drawer at room temperature. I did notice a shrinkage in the size, from how I remembered them. Would the age and the storage at room temp be factors for stunted growth? Thanks in advance Prof!!
Age of seeds and storage conditions can impact initial seedling development. Once the plants get going typically they will recover, but growers should expect a slower than normal start to plants when older seeds are used.
Vacuum sealed would only be advised if the moisture content at time of sealing was low, but assuming this is the case your idea would help increase the odds of germination of seeds for longer than most other storage methods/environments.
What works for me is I put them in brown paper envelope, then put that brown paper envelope into a brown paper bubble envelope as in insulation! Then I fold & manipulate package with tape to have a nice compact squareish ball shape. Then I place into tubber ware then fill with rice! When placing in freezer I put a thick layer of paper towel underneath container! This method from trial & error works best for me. Hope this helps
I was under the impression that storing in the fridge (~ 4degrees C) in a airtight, dark container was optimal. Is this true? Minus 20c or up to plus 15c is a big range! What are your thoughts on dark, airtight 4c in fridge professor?
As the data shows it depends on the temperature and moisture content. Is the temperature consistent or changing? In general the lower the moisture content in the seeds the longer higher germination rates will be maintained.
How many months can seeds last in their original packaging in a locked box in a closet ot cupboard without being put in the fridge if it's not an option?
@@DeBaccoUniversity Okay, that's a good thing, but what about once the bud is harvested dried and cured, if it's kept in glass jars locked up in pure darkness in a closet how would it's potency be after three or four years if it's not always cold or cool, and how would would it be if it is always kept in a cooled room in a closet?
Hi professor I have a questions, and please correct me if m wrong, you’re saying the colder the better the odds of survival for the seeds? Should they be stored together? Will bringing them in and out the freezer have a negative impact on overall health of the seeds? Thank you for this professor !
Target conditions for your seeds should be 5% moisture and -20C or -4F. Changing the temperature will reduce the germination percentage over the long term. Hope this helps.
If I may, I store my seeds in a dedicated freezer (that I just open for seeds needs, not the kitchen one, because we open and close it way to often and temperature/humidity fluctuate too much.). They are all packed in vaccum bags in small increment of 5 seeds per pack and with rice. I vaccum the bag, but not over vaccum. Then I put every 5 seeds pack in a slightly bigger vaccum bag and again with rice and lightly vaccumed. I have 8 to 12 year old seeds that still germinate over 80% all the time. Hope this helps! Cheers
If Cannabis seeds have been dropped while in their mini tube flask or shaken can they break? I worried because I've saved several of them and they were on accidentally shaken, and dropped into a bag to be put in the fridge. I wasn't the one who dropped them but the bag is this very thick hard snack bag.
I made my own seeds and don't know the moisture content. Is there a way I can reduce the moisture in the seeds prior to storage? Should I leave them next to a dehumidifier? Or does seed moisture content not change? Like how can I know without a test and how do I reduce it to make storage of my own seeds safer?
The goal is minimal moisture so ensuring that they are drying in a low humidity environment and then sealing them will be the best you can do to try and achieve the end goal.
Once dry they should be ready to plant, not sure of there is a benefit of a cold treatment, but I would recommend using 1% hydrogen peroxide to maximize germination percentages.
Some gardeners (non cannabis) toss seeds in freezer for a day or two to trick the seed into thinking it went through the winter season. Wouldn’t 3% be sufficient too? Some non cannabis gardeners recommend 3% hydrogen peroxide for healthy germination and some disease fighting. (Not trying to be snippy, just trying to learn more)
@@mcgritty8842 that sounds like a great idea based on the concept ill have to try, and i do believe deBacco has a video out with test trial covering this
I have mine in small baggies in an amber mason jar in the basement. Would it be a good idea to put a little silica pack in the jar to absorb any moisture?? Awesome video as always
Assuming conditions during sealing are proper and the plant material was properly dried this would not be needed. However, if you will be opening and closing the jars frequently than adding a pack would be advised.
I’ve always just took seeds out of nasty and grew it and never not had a problem with them sprouting or growing dank plants. Then again you can’t just go to a dispensary in my state and buy anything.. the only dispensaries we have are cbd… ain’t no one want them seeds 😂😂
Last year I started some satiiva seeds from 1984 that had been in my freezer in a plastic bottle and most germinated, and about 25% became viable seedlings
25% is better than 0% ;-)
I encourage you to share those genetics with growers around you if legal where you live. Old genetics are always a treat!
So _YOU_ found those seeds I lost in the class of 1984. I knew it all the time!
Hold on wayment…
The idea that the seeds can be freezed is stunning!
Thank's professor!
You are welcome and this is the best method (with the proper moisture level) for long term survival.
great video, thanks for sharing
i keep my seeds stored in a jar at the bottom of my refrigerator at 5C and lower with desiccant packs to keep moisture levels low. i worried the desiccant packs may have overdried the seeds however i've had 100% germination using this method and this video backs up that confidence in my storage method so thankyou very much
i have heard of seeds being stored in freezers for two decades and having been viable still
it's very useful to have some science to back up these claims
long term storage of cannabis seeds is critical as we are seeing a lot of irresponsible breeding and bottle necking of the genetics which will only exacerbate over time as the demand for fem seeds goes up
now is the time to really protect current and old world genetics, with a view of regular reproduction to keep seeds viable.
Always nice to get scientific confirmation of the practices you implement.
Seems likethey do. My seeds pop in the bottle sometimes.

Sometimes following nature is the best option.
Good morning do you have any notes to preservation of seeds
Have stored in freezer for years and years with amazing results good vid
Thanks, ensure the moisture content is also low and you will have the best odds of long term germination percentages.
You need to share...ijs
Your content is incredible. Please keep doing what you’re doing. Thank you so much DeBacco University

Not sure what you are referring to, the germination percentages are provided given the different conditions.

Put the silica packs in the larger container.
Stick them in an air tight container and put them in the fridge, this method has worked many times for my up to 24 months storage
Absolutely I have had seeds for over 4 years in a film canister in my sock drawer (with central air) and I still had about a 70% germination rate (7 out of 10 with one male) so don't over think it and never throw away seeds because you won't know unless you try.
... and now you know how to extend storage to 36 months.
@@DeBaccoUniversity yes definitely improved my plans for next time. Cheers
Prolonging the longevity of ex situ
conserved seeds by storage under anoxia
From 2014.
What do you think about their method?
Low temperate, and humidity are the key environmental factors to control/monitor.
I managed to germ approximately 8 year old seeds that were stored in a plastic meds bottle, in a drawer at room temperature. I did notice a shrinkage in the size, from how I remembered them. Would the age and the storage at room temp be factors for stunted growth? Thanks in advance Prof!!
Age of seeds and storage conditions can impact initial seedling development. Once the plants get going typically they will recover, but growers should expect a slower than normal start to plants when older seeds are used.
So best bet would be a vacuum sealed bag in the freezer? Would desiccant bag along with them be wise as well? Love your videos, so very helpful.
Vacuum sealed would only be advised if the moisture content at time of sealing was low, but assuming this is the case your idea would help increase the odds of germination of seeds for longer than most other storage methods/environments.
Also if storing in little plastic containers use some cotton ball pieces to help fight moisture.
What should you use when putting seeds in freezer a jar pill bottle ziplock bag with cotton balls?
0:25-0:26 You sound so excited to talk about this topic!
Hopefully this translates to my listeners!
You never cease to amaze me professor. Thank you for the video

Any thoughts on vacuum sealing them? curious if could benefit or harm.
This would be effective but is not a necessity for long term storage.

Your suggestion will work and keep the buds for an extended period of time, but -20 is better for truly long term storage.
@@DeBaccoUniversity So does this mean; harvested cured bud long storage is best in the freezer? Thank you
Great info
Glad you liked it!
Very helpful, so how long does just putting them in a sealed container in the basement last? Am I looking at a year + or just months?
As the data shows it depends on the temperature and moisture content. Is the temperature consistent or changing? In general the lower the moisture content in the seeds the longer higher germination rates will be maintained.
This is actually what I was looking for g job guys
Happy to help you find the information you were seeking.
I store mine in a lock box in my fridge. Had some in there for over a year, which isn’t long, but they germinated very fast.
Try 1% hydrogen peroxide to increase germination percentage as well.
Very good info to know! Maybe I should move mine to the fridge..?
The more you know.
How many months can seeds last in their original packaging in a locked box in a closet ot cupboard without being put in the fridge if it's not an option?
Odd are 18 months or less... since the moisture content is unknown.
@@DeBaccoUniversity Okay, that's a good thing, but what about once the bud is harvested dried and cured, if it's kept in glass jars locked up in pure darkness in a closet how would it's potency be after three or four years if it's not always cold or cool, and how would would it be if it is always kept in a cooled room in a closet?

How find to growers to get less comercial seeds any advice?
Grower networks.
Thank you!
You are welcome!
If your just learning this information should you put them in the fridge or would that shock them. 3 months until I need them
There would be no harm in putting the seeds in the fridge, this may also help maintain the improved germination percentages over the storage period.
@@DeBaccoUniversity gosh your a genius haha thanks man your knowledge has been bragged about by the way very much appreciated.

It would have to be very violent so in most normal cases no.
U can bounce them like basketballs if they are good seeds. They are like mini turtles again if good.
After the seeds are produced, is there a separate process required to sprout them without losing the napkin? Thank you.
Maybe this DeBacco University video can help... th-cam.com/video/KPzfZ_xFXtE/w-d-xo.html

I air dry my seeds an put them in little plastic lab tubes with screw on cabs ad a little rice to it to pull the excess moisture out and keep them dry
I was wondering how long a seed needs to be off a plant to be germinated

There are those who want an answer and those who want to know why.......
Its okay to admit that you don’t understand how science works stan.
I’m using seed this year that is 6-7 years old. They keep for many years if you are careful.
Proper storage is the key to long term germination success.
Those were some confusing layout of charts Doc
Hope the end conclusion is understood.
I have my seeds in a mini fridge that is at 45 degrees in a glass vial in a Tupperware container full of rice hope I still can use when ready
With the information presented here you now know how to maximize seed storage time.
