CLONING PROBLEMS! :(

Here's a few quick observations. Some or all of them should help resolve your problem.

a. They look small. I like my clones to be approximately 7"
b. They look too wet. I water my clones every 2-3 days. Allowing the RW to slightly dry will help promote root growth in search of more water.
c. I would also trim 33% of the upper leaves to decrease the respiration which leads to water loss.
d. Try to keep them a little warmer... They seem to root better when keep between 75-80.


tbh I disagree with all of this.

don't trim anymore off. contrary to belief they still need to photosynthesise to root best. the more plant mass you got the better the chances you got.
you shouldn't need to water every two or three days, the cubes slowly drying out will encourage root growth. I don't understand why people don't want clones to transpire? I only spray once when im actually taking them and once in the dome they don't need straying constantly. your just really encouraging mould.

make sure you ph the soaking solution to about 5.5 to 6. I wouldn't bother with superthrive, but 1ml or 2ml per gallon of any flowering nutes does help ive found, but apart from that I wouldn't add anything else.

this is just my opinion but I have pretty much every clone rooted in 7 to 14 days.. unless they have had to travel etc unrooted for a while. good luck!

hi PnP, maybe try a different method for taking cuts, i have tried every way possible to take cuts, rockwool was very high maintenance i found, misting, propagtor lids, when to open air vents, are cubes to wet, lots of pissing about that i could have been doing without really, been using a bubble cloner for years now and would not go back to anything else.

i take a cut, place it into a glass of water, then into some clonex, then straight into the bubble cloner and thats it, i will replace the water after 1 week and after 2 weeks the root system i have is amazing, they ready to go, very low maintenance works best for me, and with the bubble cloner you very rarely lose a cut, best of luck PnP.

i use a 27 site cutting board, put 2 cuts in each site and its now a 54 site cutting board ;)


they look amazing man i need a bubble cloner!

Exchange you're rockwall cubes to Root Riots, get a NEW FRESH bottle of clonex.

Snip a 45 degree angle in between a node set, and put it straight in to clonex, <important, let it sit in the clonex for 10 minutes or so, place in to root riot cube, trim a few of the middle sets of leaves in half, use a spray bottle filled with PH 5.6-6 tap water to spray the clones with a fine mist, spray the dome lid, and place on top, CLONES DO NOT NEED A LOT OF LIGHT, the less the better, I would have a 125w cfl around 1 ft away from the dome, give them a 18/6 on/off light cycle and keep temps around 80d, LIGHTLY spray them and the dome, once a day for a few days, you may need to make the root riots moist again with said tap water, after 4 days, start opening the lid a little bit, ie open the top vents and keep them open, start taking the lid off for 2 hours twice a day, depending on clones by day 7-9 the lid should be totally off, start misting them again once every other day, keep the root riots moist, but not soaked. VOILA

If I would guess you're problem it would be

Not enough cloning gel/powder or contaminated
Not sitting the clone far enough into the rockwall, stem not in contact with moisture
Rockwall not wet enough with to start
Rockwall or root level of the plant too cold
Too much foliar spraying, discouraging the plant to grow roots
Too much light
Some chemical in your mother plant inhibiting rooting

Avoid all of them things, or just do it how I do it, and you will find it hard not rooting a clone, FINALLY you may have an extremely hard to clone plant I have a plant that takes 20+ days to START rooting, that's if it does.

my clones from regular plants look like this after 12 days, although I use aero cloners

Thanks Canada, it makes perfect sense - you need to make them want to root out. I was providing too much care after not cloning for 3 years so I was over-doing it for sure. Planning on taking a final round of cuttings (50 or so) tomorrow so I'll go with something like this:


No dome
smaller rockwool cubes
tap water w/ no addatives (should I pH this?)
lightly coated cuttings in rooting powder (not gel)
indirect lighting for the first 48 hours

I've been cloning in rock wool for at least a year now, with great results. Things I have noticed that have hindered rooting:

-Too much direct light. I keep my trays practically in shadows compared to some folks. A bit of exaggeration, yes, but really I see no need for any sort of flouro directly over a dome.

-Stem scraping. Unnecessary all the way around.

-MISTING. I don't even mist my dome on the first day.

So my process is very simple and usually 100%. Like many have said, too much love can kill.

I make a solution to dunk my rockwool in which consists of Clonex solution, and a very low dose of bloom nute. I have done many side by sides and yes, the addition of the bloom nute has decreased rooting time by a couple days. So, it works for me, so I keep doing it. The solution looks like this:

Dechlorinated tap
20ml/gal Clonex solution
5ml/gal PBP Bloom

pH'd to 5.5.

I let my cubes soak for only short period of time. Very short compared to some. Like, 10-30 seconds. Basically the amount of time that it takes me to prepare my next cutting.

I don't take monster clones, but I will agree that bigger clones have better, easier success. Although, I have just as good success with small cuttings from the undergrowth.

I do use Clonex gel, but side by sides have shown me that its not necessary. So I guess you could say I'm just using it up. But here's the important thing, use a very very small dab of gel. Too much gel causes rot.

Cut at 45° angle. Don't use that prefabbed hole in the rockwool. Flip it upside down and make your own hole. This may scrap off the gel you just applied, but like I said, it doesn't really make a big difference anyway.

So here's the important part. Yet simple. After you've prepared all of your cuttings and have arranged them in the dome(s), don't mist anything. Dunking your cubes in the solution is enough moisture in the domes. Put your domes under indirect light, with vents closed. Keep temps around 75, 80 at the highest. Leave them alone. Check them in 7 days, crack the vents, and mist the cubes if they feel too light. You'll get a feel for this. Although I rarely am replenishing moisture in my cubes. But I can see using a heating pad causing them to dry out faster, which I don't use. Now from this point, I slowly introduce the cuttings to less humidity. A shock of change in humidity will cause drooping. So I will start by barely cracking the vents, then open them all the way in a day or two, then I'll "twist" the lids from the trays to allow more ambient air in. By now we are at 10-12 days and should be planting by day 14ish.

That's the way I do it with basically 100% success rate.

But keep in mind less is more. Main thing is don't mist (unless you're not using a dome all together), use indirect light, and don't abuse your cuttings by scraping stems.

Oh and also, very important to keep it CLEAN, and when taking cuttings be sure to get them right into a cup of water until you're ready to get on with the process.

Lots of peoples' methods here, but I wanted to share mine. I feel that shitty cloning results comes from trying too hard. If you follow the simple steps I listed you will have success, regardless the particulars.

Not sure anyone has said this..
Are you wiping of excess water from the dome when you take it off?
I found wiping it of, letting the plant have some fresh air for 15-30 min every day, and giving them a spray before putting the dome back on has given me 100-99% success..Other factor as well, but everything else has already been said.. but off course different strokes for different folk..

add few drops of bloom fert very very lil
ph those cubes to 6.0 . everything else looks good.
folair spray with drop or two of bloom in a spray bottle of tap water

Too much leaf left on, they only need 2 leaves

Are you poking a hole through the cube and pushing the stem right to the bottom?

My clones vary but they can be 2" long if that's all there is, so size is not the problem

I use tap water with a ph of 5.6, THATS all, pumps 24/7 lights 18/6 I trim the clones though, I also keep a dome on for 2-3 days, I use Clonex, although cloning solution is apparently not necessary, keep an eye on the ph it will change most likely, after roots have arrived I slice through the plug and wrap it around the roots

I saved at least $200 building this, and it was actually a pretty fun project

That looks the business , cant imagine why peeps buy them rather than DIY.

The only reason i dont use an aero anymore was due to the pump failing and loseing some good clones in a day , if a bubbler craps out you have no rush to find or fix it.


One detail i have noticed is that the cut stems or a higher node actually sitting in the bubble zone , are usually the first to show roots.

Could be the physical disturbance or better oxygen levels , finding a detergent/foamer that does not dissolve plant stems could knock a day or two off , maybe.

A heel type cutting where you pull a sidestem off and tidy it up seems to be particularly reliable.

There can't be ANY light leaks!

I had problems before I light proofed my cloner as well..

The roots were trying to grow IN the collar! Because at the time was the darkest area.

These plants will literally grow anywhere.. Even in the 1/2" space the neoprene collar allowed the plant to grow.

So as soon as I light proofed the container, not 3 days went by before I saw roots hang down into the cloner.

1. Light proof
2. Water
3. Air
4. Small amount of light

That's it!

Don't worry about gel, or anything. Don't even cut at a 45 you'll still get roots

Folks I'm having some issue after going from cloner to soil, seem slike it starts in the cloner: roots just fine but @ about 9 days in the tops get stunted and it carries over to the soil and eventually comes out of it but its costing me a few weeks of down time all together.. Any suggestions ideas?

JBomber79- Sound like a humidity problem. One idea could be to put a plastic bag over the plants for a few days after transplant,like a make shift dome.. that way, if there is a humidity problem, they get a little more time to settle proper.Hope this helps..
All the best

i use coco to clone. no dome. just put clones in an area with no airflow and breath on them twice a day. getting very good success. good luck with your new aero cloner!

these have all rooted now
