Cloning- WTF, no visable roots after 12 days?

Hi guys. I cloned some stuff last Monday. Not Monday 5 days ago but 12 days ago. I still don't have any visable roots. I took a bunch of clones and after 12 days about 2/3 still look perky and upbeat. A few have some slight yellowing but nothing too drastic. What's up with my clones? How come there aren't any visable roots?

I'm cloning them in rockwool cubes. I followed the method posted on the forum where you soak the rockwool in a 300 ppm solution for 1 hour.

Since then, I've only sprayed the dome and wet the cubes only when they started to dry out which in this case is about every 4 days. I never drench the cubes, just wet them.

So what gives? Where are my beautiful white roots? I checked alll of them last night and I didn't see a single root.

Also, temps are 80 at the highest, 69 at the lowest. Humidity is really high in the dome. I'm not having too much trouble keeping the mist on the dome. Lights are a 250 mh about 3 feet from the dome and not directly above it (about 1 1/2 ft off center of the light). I have a heating mat underneatth the dome.

Pics to come later on if i don't see some beautiful roots!

sometimes two weeks on some of my clones...i will tell you that from my experience clone domes and misting them only slow down the process...peace

Actually brainthor; ime I have found that misting and domes work well as long as you do not overdo it with the humidity and misting.
I have gotten clones to root in 5 to 7 days and 10 to 12 days if they were refrigerated.

Did you also ph adjust the solution you soaked it in? You need to ph adjust rock wool cubes before using them......

Cold clones will root slower and you do not want that; you need to keep temps stable; keep them in the 75 F range; to hot and you will have to mist more often or keep misting the cubes; you do not want that.


Another thing; get rid of that MH; all you need right now is fluro tubes or some compact fluros above them; they do not need to be close. The reason why your leaves are yellowing is from delayed rooting; it also can be from plants using stored nutrients in the leaves to help it root.


When you took the clone did you cut it at a angle or cut the side of the clone a bit? Like remove a small layer of the lower part of the cutting so roots can have an easier time coming through?


If I do not see roots in another 4 days I would crack open a small piece of rockwool and carefully check to see if roots are coming out.
 
I have hdf that roots in 7 days, and the Jedi takes 14 days. Just remember that if you can gently squeeze the rouckwool and water comes out it is too wet and that will stunt root growth. After the rockwool is soaked I shake the cube to get the excess water out so the cube is super damp not wet at all. If you gently pull one of the clones out of the rockwool and feel any resistence there are roots starting or already there, if it slides right out well no roots.

i usually have roots within a week..but some are slower than others...bottom line it comes down to vigor if conditions are proper

I have found 99% Clone root rate in 14 days in a Bubbler Str. Water NO PH and a Small amount of light. To much light will hurt them. NO NUTES NO PH Lots of Bubbles. NO Domes and dont Mist

My OB1 took 36 days to root in a peat pellet and we are thankful that she would even root as the OB1 (and the Oregon 90 in her) are notoriously hard to clone.

WTF! 36 days and the damn thing lived??? I bet she yellowed like mad too!

You got a pic of that clone by any chance???

I don't, but she went very pale green at the growing tips, then greened right back up when the roots took. She really didn't yellow too badly, funny enough.

This plant has a very tough and hollow, almost straw-like, stem. Once rooted it is very strong and a good grower. She is LST'd and growing along nicely now, waiting patiently for some room under the 12/12 sun.

Funny thing is there is some pale mottling on some of the older leaves. The mom had the same thing and grew out of it so I am attributing it to an incomplete or inadequate root system. The new growth seems fine.

250mh at three feet is way TOO bright.
Your cuttings need to put their energy into making roots instead of trying to do photosynthesis with the lighting.
Put a couple sheets of regular white printer paper on top of your dome, to act like a shade, under that mh light and you'll see results in another week.

try a bubble cloner next time...its so easy under 10$ and in 2 days, i already see a tiny root .5cm long comin out

when you mistdo you use just ph water?

when i mist my cuttings i use ph water and some either canna rhizo or bcuzz root stimulator(whichever brand i have at the time).

have even used voodo juice on some cuttings i took recently which were heavily pistilled up and they rooted nicely in about 2 weeks.

I gotta get this guy to build my cloners - I usually spent 30-40 for a big pump, couple air wands and a heater - - the results are "priceless"


Rockwool never worked for me, but on the bright side - if your cuts are still standing - they haven't given up the fight.


Did you use any rooting hormone?

I never did get to many clones to work in rock wool either Solar; always stuck to using peat pucks!

I was trying a bubble cloner when I switched over to hydro; got 5 out of 10 to root; first try; I am sure I could of perfected it better if I had the chance to.

Solar: His rockwool was soaked in the cloning formula he does not know about.
I think it would be better for the tips to soak in the hormone themselves.
I always did it that way; use a little in a lid and slice a small opening layer on the tip of the clone and put it in the hormone after I let it sit in some water and a drop of superthrive.

then would use the hormone and put it in the medium.

another thing you could try is giving the clone a gentle pull and if it doesent pop straight out then you have some rooting going on.just remember be gentle.

I had a sick garden and started using Clone-X gel, - cut, dip and let it sit for about 10 minutes befor putting in the cheapo-aero. It makes a difference - in a good way, even though I do tend to get a few more that go limp. (many of those are saved when I re-cut the bottom)

I think the rule is, keep trying till ya find the right system for your gig

I tried this today and about 3 of them are toast. There was minimal rooting going on. I did dip them in cloning gel prior to putting them in the rockwool. I would say that even at this point a full 14 days after the fact, I have not roots and most of them look fine. Most of them have some type of rooting going on in the cube, just not any exposed roots.
