So just before I give up on cloning, I'm going to throw one last attempt at it.
I've got one healthy female that I have been vegging for 2 months. She's actually Showing her hairs quit plentifully now. Don't know if that has anything to do with my failure to produce a living clone, yout tell me.
My basic procedure is as follows:
I took cuttings from the plant, about 5" long to be exact. I cut the stem at a 45 degree angle, but did not split it, I left it whole. I dipped it in water, then dipped in my rooting hormone, see attached photo.
I then stabbed it in a 2" x 2" x 2" rockwool cube that I had soaked in a water/ rooting solution mixture.
I have them in a humidty dome, see attached, and have tried the vents in multiple configurations.
Temps are 75-80, hunmidity is ambient, but probably 50% for sake of argument. I haven't fed any nutes and have not watered them at all, I assume the soaked rockwool is good for that. I have however misted water in on the second cloning attempt, I did not the first time around.
They are on 24 hour light under 6500k cfls.

The only thing I can think of is, and I thought I had it fixed is.... my water is 6.5 ph, and I know that's a bit high, so I used the rooting solution in the water I soaked the rockwool cubes in.
Anyone else have any ideas?
These things just shrivel up and die. The first time, with ho humidity dome it was overnight. At least with the humidity dome they lasted a few days. I pulled the stem of one of the dead ones and it zero, I mean ZERO root growth.
I hate the idea of gowing back to seed grows.

you are taking to big of clones. you only need like one node of new growth and one full leaf and the stem frome there down to the next node.

also keep the humidity high and mist them every day

it will probably take a couple weeks you could also put a heat pad under their tray that will help speed things up.
also you may want to try an easy cloner they are easy to make and arent that expencive to buy any way i think they are well worth the $170 i go 25/25 almost every time

Thanks for the input to all.

I'm going to try 2 new ones tomorrow, and will cut them shorter than the previous attempts. I'll mist them daily.

Can someone tell me what purpose the vents serve on the top of the dome? How long are they supposed to remain closed? Is there a target humidty level for the clones?

Hi. My personal opinion rockwool is little bit hard for 1 timer, use jiffy plugs much more easy to clone with them. If RW is to dry is not good, to wet is event worse. So try with JP you will like it.
Regards

i have a question as welll. if the temperature is high do the watts in the light really matter. the light we use goes to the high eighties which we think should be fine for one plant.

I've had a 95% or better success rate with rockwool, but my system is slightly different;
Even more important with big clones - no air on the cut, do the final cut underwater and immediately go to rooting gel.
I use the rockwool plugs ( the ones that fit into the cubes ) which are a cylinder and have a slice on the side. I carefully insert the stem into the center from the top, where the slice ends.
I keep my plugs in a tray that has standing nute solution. The clones, when small need constant contact with liquid, once the first true roots come out ( which you can see thru the cut ), you can back off on the liquid and give the roots more oxygen.

To answer about the dome vents : The target humidity for clones with no roots should be close to 100%, so keep the vents closed. As roots develop, you can decrease the humidity.

From what you wrote it sounds like you have the concept down...could be some variables tho...For starters, if you have had trouble in the past with clones not rooting, check your cloning gel...a common mistake is letting the gel go bad because it wasn't refridgerated. Could be molding or seperated. Another thing is lighting, another common mistake is TOO MUCH light...They don't need much to start new root systems, infact less is more when developing new roots. As long as you have wet rockwool and humidity in the dome with a semi-sterile environment, I don't see a problem with your techniques..

Cool. I started 3 cuttings last night, we'll see how it goes. They appear to be drooping a bit, but they have been holding steady.

I've been misting the inside of the dome every couple of hours. I have a hygrometer that shows it to be in the mid 80%'s pretty steady.

How long should I anticipate it being before I can put a 12" plant into flower? 2 weeks? 3?

Never done this before, obviously.

Thanks.
