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

Yes I trim off about an inch of so after removing from the fridge. I dip them into rooting powder right before putting them into cubes or coco.
But I let them sit in water before that to perk back up.

I always Put mine in plain tap water for 24 hours.I have the best luck with Chlorinated Tap water its the craziest shit.Tried putting clonex solution in and it turns the stems slimey so i dont do that anymore just plain tap water.Last clones i got didnt take and i suspect They had them in a cloner machine for a few days and pulled them out and shipped them.When i pulled the wet pape towel off the cuts they had a slime like the clonex water on them.I cut half an inch off soaked them for 24 dipped in Hormex#8 into ph and clonex fed blocks they went mush all the way to the top.

@Slammedsonoma420 those look amazing for 100 days in the fridge! Have you been doing this for a while? What kind of rooting % do you get? I need to give this another try, just got mushy stems last time :frowning:

Not too long. I read about it in a post from @Budderton maybe 1.5-2yrs ago. The snips at 60 days have about a 70%+ success rate.

Thatā€™s awesome! 60-75 days would be perfect.

Duuuuuude, you need an award of some kind for this thread, no joke!!!
Iā€™ve been looking for a way to keep moms/dads over the summer months as itā€™s waaaaay to hot in my place to keep any, and have no spot to grow outdoors.

Now with your method, I can just keep a mom/dad tent and let them get a decent size for a nice thick woody stem and take a bunch of clones at the end of June, and root them middle of September.

Bro you straight up gave me a game changer.
MANY thanks :pray::sunglasses::love_you_gesture::love_you_gesture::love_you_gesture:

Itā€™s nice to see this topic revived, and I have something to add, an interesting if not indicative example of the method.

Back in early June I did a major defoliation of some prized mother plants. In the process I chopped beautiful clone candidates, full of healthy leaves and thick firm stems. Beauties, just laying on the trim tray, enroute mostly, to the compost. A Greek tragedy.

But all those freshly cut healthy cuts didnā€™t go into compost. I took a handful of the nicest stems and ran them through the Long term storage sterilization protocol then tossed them into ziplock bags in the fridge. Then I left on some lengthy journeys.

I didnā€™t trim them before cleansing them. Instead of vented jars, I shoved these beautiful stems into a gallon ZipLoc freezer bag and tossed the into the veggie draw in my fridge.

Iā€™ll let you judge for yourself. I reckon I could sprout them easily. Havenā€™t done it, donā€™t have the time, but Iā€™d betcha theyā€™re viable.

Hereā€™s a pic, have a zoom.

So, hereā€™s my report: Just clean them thoroughly, shake off excess water then straight-direct into a brand new ZipLoc Freezer bag, half filled, tightly zip-locked and set in a quiet area of a frost free fridge.

Easy Peasy. Four months, viable?
Surprised the shite outta me.

Small update on things I have learned:

I think age wise, weā€™ve more or less reached the limit without adding some kind of a substrate. Typically you would use an agar gel with lab grade hormones as your ā€œnutrientsā€. Most people would not have access to these. I get them through a friend at a university when I need them (not illegal to get just tricky) but they can be very hazardous to work with so not something I would advocate for casual growing. I donā€™t know of a way to add standard nutrients to agar and sterilize it, as once you heat it the nutes can release potentially toxic gases. That would be the thing to find out, sterilizing nutrients to use in a substrate. Maybe we got an organic chemist around here.

I do know though that the sterilization will last upwards of 6+months. I let old cuts just sit in my fridge from when this post was originally written and I just threw them out a couple weeks ago. I didnā€™t think to take a pic for an update but here we are. The cuts had obviously deteriorated but the jars(x2) were completely free of any mold or rot or any other kind of growth.

Looking forward to getting back on OG now that the season is coming to a close. :v:

I saw the sterilization mentioned as a way to clean cuts that were potentially contaminated. Has anyone tried this?

Iā€™ve been thinking I would avoid cuts to avoid bringing any issues into my grow, but if I could clean them more thoroughly than a quarantine and hope, that might change the equation for me. :thinking:

I wonder if there would be longer shelf life from plants that have solid wood stem cores vs. hollow stem and taking woody cuttings with decent foliage. Has anyone tried this?

Yes you can use this to sterilize clones you get from other people. Even if they are in some kind of medium or cubes, just dunk them upside down into the different liquids or do this before you root the cuttings.

Interesting idea. In general, cuttings from woody plants do keep longer.

That is excellent to know. Thank you for confirming!
