Stem Scraping

just under the 'skin' is a layer called the cambium

its from here the rootlets form

its also why gardeners cut their stems at 45 degrees

to expose as much of the cambium as they can

the cambium is easily infected thats why you gotta see this as a sterile situation

many noobs like to feed their cuts, a mistake waiting for the bacterial infection to start

simply smear household honey onto your cuts and insert to ur bubble cloner of medium

good luck
Just about to start cloning with gel and a starting propagator, contemplating rock wool cubes or rapid rooters, any exp with either of these?

I recently tested a theory I picked up somewhere and found it very effective. Scrape outer layer of the stems of clones after about 2-3 days in the cloner. Taking off the skin where you want roots seems to delay root production but when roots do show they show up big time.

Everyone may already know this but it's new to me after 15 years of learning. This is the most useful technique I've picked up in a while. - Cheers
i use a every board to sand the stems so lightley

Both can have their issues

with rockwool to much water can be a real issue, squeeze some out first

with rooters, ph is vital, as the cut develops, it adjusts to the Pf of the rooter

but once the root emerges into ur soil later, it may struggle to adapt to ur soil

I found a bubbler avoids both of these simple but vital flaws

stay sharp

good luck

ps try honey on a couple of cuts

I use bubble cloners also, having moved from Root Riot plugs (same as Rapid Rooters) as I struggled to maintain humidity without misting. In plugs I used to 45degree cut and scrape although I can't say it was necessary.

In the bubblers I find roots grow out any which way from the stem with zero scraping, so I think its really splitting hairs to be honest. All other variables are much more important to cloning success.

Another thing to remember is if your setup is prone to pathogens, scraping stems is increasing the potential for problems. Like open wounds. Same goes for if you use bubblers/aeros with high water temps.

Is anyone on this forum active right now that cut clones successfully??
Sure, I've done hundreds of cuts in the last few months at least a thousand over the years. I'm working on a order for a warehouse of a few hundred clones.

Important factors, no particular order.

1) Get the best cut from the plant.. Actively growing healthy and I prefer top cuts.
2) Sterility.. Use a clean tray, clean water, clean hands, disinfectants in the water help.
3) Proper environment thats consistent. proper heat, humidity, air content in the media, PH. All important. Ventilate every day.
4) Cannabis does not need a rooting hormone, but it speeds up the process. IBA with NAA or Just IBA. They do react differently.
5) Different cultivars of cannabis can root easy or can be hard to root.

If you think stem scraping works, or angle cuts go for it. I just think its a little piece of the big picture.. no stem scraping here.

Agree with all your numbered points. None of which conflict with this idea. Not really seeing anything in your response that has anything to do with the idea but the obvious points about clones and and then that you aren't going to try it and/or are not doing it currently.

All of those things are what I practiced before trying this and I was successful before trying this.

To my surprise what I found was many, many more root structures formed with the same size plant that I otherwise would have had a healthy but smaller mass root to start with. I guess this is similar to strategically cutting to create more tops up above.

I posted this idea because 1.) I was surprised that it works and 2.) who wouldn't want bigger root mass to start a new plant?

If you don't want to try it. Don't.

Ok ive read all youre ideas THANKS ALOT FOR YOURE RESPONSES im pressed for time kinda bcuz im suppose to be going down south for a week in march i wanna be done by then so i tried to cut two more from the bottom i scraped this time used rootek(orange gel) and places in rapid rooters soaked in RH water but not super soaked cuz dey molded last time theyre looking good so far not wilting which is good i guess and i guess right? Im limited on money right now if this dont work then im getting the cloner when i get my next check i need 100% goddamnit

I'll start by saying," I don't know shite".
However,
I take any old cut
From any part of a healthy plant
45 degree cut
dip in Clonex
place in small rockwool cube(prepunch a hole with the other end of the scalpel)in a standard propagation tray
Water until it JUST starts to run off with a little (as directed) House and Garden roots xl
Cover with standard lid
Vents closed for first week
Open for second
Watering when the tray feels light
Very little light
With this method I see 95% success

Gloves
New trays
New scalpel
EVERY TIME

I've never needed a fancy machine
