A Guide to Long-Term Clone Storage, 2+ Months, And a Continued Experiment to Reach 6+ Months

Still haven’t even harvested, much less cured the plants the clones originally came from… when I do, if there are actually any keepers I might try it. As you say, there’s a chance and it’s not like I have anything to lose. Fairly sure there’s still no mold, at least.

Greetings @Naptown916,
I have yet to be successful reviving an unrooted cut after more than a few weeks, but it’s likely I’m missing something in the way of technique.

I’m hoping for an update on your success “Long Term.” Have you made it beyond 2 months with a revived clone?

Regards,

Hey @GrouchyOldMan . I just did a post, showing how I “wake up” snips that have been stored in the fridge.

Don’t mean to hijack your thread @Naptown916 .

I was able to get to 3 months but could not do a reliable 4 month revive.

When bringing them back the common issue I saw was stems that had broken down. For them to stay viable longer the stems have to be much thicker than a standard cutting. If you have any pics to post we could eliminate that as an issue.

Waking them up is just trial and error. I worked most of that back from @Budderton and his method. His journal had lots of examples. The only thing I’d recommend in addition is some rooting power ups. SuperThrive or another b vitamin booster, rooting gels, foliar feeds etc.

I never tried this but if I was going to go back to trying for 4 months I would root them in tissue culture rooting gel. Because you’re not storing them, you wouldn’t have to worry about sterilizing the rooting gel but it would provide the most stable and aggressive rooting environment since you can customize the strength of the rooting hormones. I think this would make a drastic difference in rooting success and time to root.

No problem brother ! Glad to be a help !

If only we could figure out how to limit transpiration while in the fridge !

Would a silica pack help?

if i recall i tried that the very first time, it was much worse. sucked all the moisture out of the snips.

Sounds like maybe some experimenting needs to be done.

Mine all molded up, I believe they may have been a bit too wet… not sure. I’m going to attempt once more in a few months. I would like to get this method down as I need a reliable way to store cuttings while away in Colombia for months at a time.

I tried two lots of clones in the fridge, one I removed from the fridge to check on them and they got covered in condensation that ruined them soon after…lesson learned moisture is a problem.

The 2nd lot were never taken out they just got left in a bag untouched and they managed 8 and 10 weeks, I think longer is feasible?
They didn’t look great overall but they rooted fine.


There’s others I bleached with led during the learning curve but they still rooted.

I vaguely I remember some cloning agent/snake oil that allegedly acts like a wax or something, iirc the idea was to prevent transpiration?

I should add…the plants i cut the clones from were at pre flower stage, idk it could be relevant?

Just a thought?
Salt and water paste will always maintain 75% humidity, that might work for storing clones while preventing condensation forming in the bag.

The salt paste should absorb any excess water and also give it back out if/when needed?

We are at 100 days on these snips, perked back up nicely. Will root for sure.

100 days? Nice @Slammedsonoma420 ! Did you clean them before storing? Where they kept in baggies or Mason jars? Apologies for all the questions, just like to know the process, when things go right. I’ve found that the cup being in a dome helps bring them back and keep the light levels low for the first few days, as they will be sensitive after being in the dark for so long. Doesn’t look like you need any advice though, you’re nailing it!

these were snipped from the mom and thrown into a ziplock baggie, remove most/all the air just by burping the bag lightly. i have never cleaned/sprayed/dunked the snips. just stuck them into a small pelican case, and tossed them into the fridge (38-41F).
i had a few other snips in that same pelican case but different bags, they didnt fare as well. the only difference i can see is the size of the snip. the larger ones looked much better and had no signs of mush/rot.

the first 24-36hrs after removing from the fridge i stick them in a shot glass of plain water(not even phed). after they suck up all the water they need i stick them in media of choice and root as usual. these were just testers i was going to throw away so im not going to stick them in any media. ill either leave them in the shot glass or just toss them in the trash.

Very cool @Slammedsonoma420 ! Yeah, I find the slips with larger diameter, more woody stems hold up much better in long term storage. I recently pulled some out that where stored for 15-16 wks, as an experiment, and they where all moldy. For me, 8 wks of storage has been the sweet spot for them coming back consistently. Great tech to have at your disposal!

i definitely agree with 8-10 weeks being where they start to badly degrade! im not sure i would know about the “tech” unless i had read that post you made about it a few yrs back!!! thank you for that, and everyone else who has tried/tested and posted their results.

have a great rest of your weekend.

Very nice. They look like they hardly deteriorated or aged at all in that photo. Great work! Very impressive! What strain was it? Do you have a photo of the mom? Curious on the plant health/maturity when you took a cutting

Golden triangle. Thanks. they held up well!

Are you guys retrimming the ends of the cuttings before you pop them in blocks ?Or are you just taking out of jars or ziplocks and then dipping them in rooting solution and popping them into blocks?Are you scuffing up the clone stembefore dipping it?
