2 Weeks - Clones not rooting :-/

[ziv2002]

Hey!

I toke clones on the 12/11 - put them in rockwell and inside a dome with 95% humidity for
a week, then raised the dome for a few days (humidity dropped down to 70%)
and then toke the dome off.

I sprayed them every day with plain water and in the last week i watered
them with plain water twice.

They look pretty healthy but they don't root - why is that?

Re: NEED ASSITANCE with Cloneing
To be successful cloning, you first need to have the right tools to do the job:

1) Clean NEW single edge razor blade or exacto knife.
2) Heated seedling tray with humidity dome or aeroponic cloner.
3) Cloning gel or powder / hormone supplement like Superthrive.
4) PH corrected water (6.2-6.
5) Mild lighting (40w equivalent CFL is what I use)
6) Rooting media (Rapid Rooters, Rockwool Cubes. Peat Pucks. or just well drained soil in a
plastic cup)

I will tell you what works for me and I have a 95% success with this method. Once in a while there will be a cutting that just does not survive. Others here have similar methods that work for them. My advice is let others weigh in and develop your own style that works for you. I have had clones from plants that were 6-7 weeks into flower grow roots, but they take a long time to transition from bud to veg. Once they grow past the bud though, they tend to develop several main stems/stalks.

Here's what I do:

1) Take my cuttings from lower half of the plant. 45 degree cut with NEW blade, then I
scrape the outer layer of tissue from stem about 1-1/2" from cut.
2) Soak fresh cuttings in luke warm, ph adjusted water with Superthrive hormone added
for 30 minutes. This lets fresh cuttings drink in vitamins and hormones.
3) Apply rooting gel or powder to fresh cut area. I use a gel now, and a little goes a long
way.
4) Insert treated clone into rooting media of choice. I like Rapid Rooters, but the others
will all work. I pre-soak the rooting cubes in same Superthrive solution as above. Make
sure rooting cube is SLIGHTLY DAMP...many a clone die from drowning.
5) Put cubes with clones into seedling tray. Heating mat should keep the seedling tray at
around 80 degrees.
6) Pour a thin layer of ph adjusted water in bottom of tray, about 1/2". Put humidity dome
on and your good to go. Some on here don't use domes, they work for me.
7) I keep my clones on an 18/6 light cycle, others use 24/0. IMO, the 6 hrs rest helps.
Just an opinion though, not a fact.

NEVER let your rooting cubes/media get saturated,they need to stay slightly damp. you want oxygen to be able to get to the root zone for success. There are a lot of ways to get plants to grow roots, this way works for me. Once you get the hang of it, you might want to try to build an aerocloner, but thats a different lesson.

Good Luck to you and I wish you great success.

Thanks a lot man!

By the way here are two pictures:

 

[UnkleFester]

if you are interested, i use a b1 soak (when i remember) on the clones, and i use honey instead of clonex and the like. i cut 54 clones last time and kept 47. but i was just looking for the stronger ones and probably could of had 50 if i wanted to wait the extra three or four days.. sorry to babble, kinda stoned

 

[Gianttee]

cuttings look healthy, sometimes i find that if the mother is growing slow the clones takes ages. i also don't have so much foliage on my clones. the rock wool should weigh about 45-50grams without the clone. its hard to say but yours look a little too wet. mine tend to have dry spots on the rock wool, that way when it roots, they go searching for water quickly. pull one out and have a look to see if they have shot!

 

[Dankfactory]

Agreed with comment above: your RW is too wet. Personally despise RW for anything related to growing but I've used it countless times. Prior to placing the cut in RW you should "fling" out any water that has succumbed to gravity and is collecting at the bottom of the plug. The water should be evenly distribute throughout the media; call it approx 80% air, 20% water.
Put your dome back on, and try to lighten up those plugs a bit.
I take trays of clones monthly in peat, as well as bare root cuttings in a chilled aero system and don't even remember the last time I lost one.

I have the same problem when I clone. They live but no roots. I found that if you plant them after trying to clone for a while in soil they will start growing. Many years ago I remember a professor at my university when I was getting my agricultural degree mentioning that when plants feel soil at its base it activates a hormone to start growing roots. It works pretty good for me. But really next time I need to step up my cloning game. Good luck my man.

 

[bryan oconner]

you never told us our temps ? are they between 45 and 65 f ? any hotter it gets very hard to impossible to get them to root . and also why not go hydro ? keep the water about 60 f with very little 18/6 purple preferred if not then blue light very weak about a 30 watt cfl strength . leds work great . do not use strong lights to clone common mistake . maximum of a 60 watt cfl 18/6 unless you have a shit load of plants then add more weak lights feed plain tap ph water

 

[caveman117]

I feel like it could be a few things, generally when I take cuttings from flowering plants they tend to rake longer.
also I notice some strains root much better with a heating pad wrapped in a towel underneath the tray (just what I do, if its in a place that gets wet id suggest finding another way to heat it).
leaving the medium too wet also slows rooting time for me. when I put my cuttings into my pellets I give em a pretty good squeeze to get excess water out.
also i like to really make sure my dome and tray are bothclean every time I usethem. ive noticed ssignificant drop off I'm success rate for every consecutive run without cleaning.

Between 45 and 65? Any hotter its get impossible to root? What!??? I would love to see a quickly rooted clone in 45ºf

 

[dandyrandy]

I use soil in cups with a dome and heat mat. I find that I was keeping the soil to wet. After a week I let the soil dry out a bit. If it's to wet the plant won't need to send out roots. Also promotes bacterial growth. I tried bublers etc and simple clear Dixie cup dome tops over another Dixie cup bottom makes a single plant dome. Cut the clear top so it fits inside the bottom sitting on the potting soil. Drill holes in the top for venting. I pull the dome after a week and force the cutting to send out roots.

It's obvious you have zero fucking idea what you're talking about, and based off of this post are almost assuredly a substandard "grower." At 33 years old, i suppose I'm not exactly old, however I've been cultivating cannabis since junior high. That equates to roughly 20 years. I'm not claiming to know everything, but I've run countless organic dirt rooms, have blown up entire houses, I've been through ebb and flow when that was cutting edge hydro, and now I own a home with a fully sealed room with multiple inoculated DWC Res's with chillers plumbed in series. Let me assure you, grasshopper: chilled H20 possesses an exponentially higher DO2 content than at temperatures above approx 62 degrees. I have run my chilled cloning res at sub 50 temps multiple times with nothing but glorious, knobby, calcification at the cut site. So Au Contrair Monfrair. Apparently the more prestigious and obscure levels of hydro, specifically water culture, are more advanced than your current state of knowledge. I guess that's a nice way of stating that you have zero idea what you're talking about. Your license to employ condescending emoticons is hereby revoked. Carry on.

First of all, in reference to his pictures he is not using a hydro setup, so when asking what are his temperatures that usually dictates the air temperature, not water. If you are rooting your clones in 45ºf air temperature, YOU ARE AN IDIOT!!!!! If you have been growing for so long you should have been able to determine what I was saying as the previous statement I was replying too was not as transparent. So in regards to him using rockwool, no, you are wrong. Dick

Have you checked the temps right there?

I'm glad you mentioned Rockwool. Please, by all means, enlighten us as to why a lower temperature in the dome, with optimal RH remaining intact, and regardless of choice of media, in this case; RW, will inhibit the calcification process of the cuttings.
Also, please explain how you deduced that quote" he is not using a hydro setup."
Oh , how amusing!
Please explain how RW isn't Hydro.

Let me go ahead and quote ed rosenthal, " When the temperature falls below 40° F (4° C), marijuana plants experience tissue damage and require about 24 hours of warmer conditions to resume growth. Young marijuana plants are SOMEWHAT tolerant of low temperatures" so yes young plants may fight low temperatures. That fact that you are arguing in support that 40º temperature, regardless of proper humidity is fine, is crap. Can you get away with it? Yes, but why would you give that advice? Why wouldn't you give advice based on the most ideal settings? I agree that I may have used the term hydro liberally, but to me he isn't in hydro. He is using the rockwool as a substrate as of now, and is not directly irrigated or even on any type of hydro system. He could decide to put the rockwool into soil which would not be hydro at all.... and if you look at the original quote I was sighting from Bryan o'connor he said that anything over 45-65º will destroy root growth, which in itself isn't true.

14 days is not uncommon in rockwool .I don't spray my clones, I spray the inside of the dome. Also, I did not see what you used for rooting hormone. some hormones root faster than others.

That's your arrow in the quiver dude? A little Google search and some parroting of what someone else has written? How profound.
In reality, there's a reason why the self proclaimed "Cannabis Gurus" and Mag outlets are not respected within the community. High Times for example. Find me one legitimate grower that pays any homage to the laughing stock that is the Cannabis Cup.
The forums are the tangible force behind real progression within this community. Period.
Further, when did we arrive at 40 degrees? Wasn't the poster above referring to a range
of cooler temps, if I recall correctly, in the 45-65 range? Why stop there. Why don't we just knock it down to 35 degrees, or 30 degrees if you feel that will bolster your rebuttal, even though that obviously wasn't what was stated.
Your last statement simply doesn't make any sense. You didn't even understand what the definition of Hydroponics was( took "liberties" as you call them) and are now backtracking by pontificating with pure conjecture on what he might do with his Hydro media. If that's become acceptable retorhic in the forum setting, than maybe he'll weave a friendship bracelet out of his Rockwool when he's finished. Theres all sorts of possibilities.

If you're going to be a dick to people, you better be able to back your shit up.
Carry on.

 

[xmatox]

I said Liberally, which is the correct term. There are plenty of people that grow that reference to grow books all the time. I never referenced cannabis cup so who cares. All I said was you should not aim for that low of a temperature. You grow, however it is you grow, but I make a very good living off producing medicine. Are you the cannabis god? So you obviously spew off someone else's shit? I can see the military getting the best of you with your attacks. Again, I don't care what you say.... Advising someone to grow in the colder temperatures isn't a good move. You tard! You attacked me originally off of water temperatures when I was referring to Air temperatures, and now you are trying to stick by your decision to attack me by continuing to do so. I am assuming you are a vet due to your "carry on" comments. Your original comment of " I have been growing since junior high, so that equates to 20 years"... Kiss my ass! You were growing in the military? You were growing while living with mom and dad? doubt it. What poster above? 45-65 where? Where is your grow community that you speak of that dislikes experienced growers again? BFE?
