No roots after almost a month?

As the title says. I have a small cutting that has been in and out of a humidity dome and through numerous sprayings and various dosages of light while sitting in Rockwool.

The tip over the better part of this last month has become swollen and black, and there are absolutely no roots what-so-ever. Yet every leaf is green, healthy, standing up, and there's even 2 new set of leaves that have went from being a tiny bud to almost half the size of the other 2 set of fan leaves now.

What's the deal? I'm glad it's having fun growing but I want some roots!

I wish I had a picture but unfortunately I have no way of transferring photos to my laptop right now. It's not much to look at. It's just like a regular cutting but the tip is black and swollen.

Thanks!

How did you prepare for cloning

Ok did you presoak your RW in blooming formula? Did you flush before?

I had an aeropropagator with twelve in, 11 rooted in a week - one took 3. Beltin' now tho...

My friend prepared the cutting. He just soaked the rockwool in water, put some hormone powder on the clipping after the cut, and stuck it in. Misted it and gave it to me later that day.

I just read another thread on the forum where a guy did a new cutting above the "black tip" and was able to get the plant to root. So I decided to pinch off that tip and pinch off a weird growing set of fan leaves since it was near the tip. That particular set was heat stressed for some reason and was not healthy at all anyways. The other leaves are a lot greener. I went ahead and put it back in the cube with fresh water. Misted the leaves and topped with humidity dome. I hope I made the right decision.

Thank you for your post though. I am going to update with results I guess.

Maybe spray cuttings every couple days, but spray the humidity dome. Also let the clones get fresh air once a day.

Thanks Z.

So far the surgery has been a success. I noticed that the new cutting was showing very very slight heat stress on its most dominant leaf (it wants to be the tallest) so I lowered my bulbs spectrum down to about 2700k and moved the light higher just for a couple days since it's probably a little bit in shock. Seems to be responding well. I have it on 18/6 right now and the humidity monitored around 75-80%. I spray the cutting when I first pinched the black tip off and I re-sprayed the small humidity dome just a few minutes ago. I decided to open one of the screwdriver-sized holes for air. It's standing tall and completely green right now so hopefully all works out!

Just dont spray to much on the clones. Look Albfuct's cloning in rockwhool under hydroponics. Also check out sublbc's vids on youtube.

do you pull the cutting out of the rock wool to check if its growing roots ?
you know that new young roots are very fragile?
if there are the beginnings of baby roots and you keep pulling it out you will just be breaking them off and nothing will come of it.
you originally also said that you are trying all sorts of different things. try sticking to one thing. if a cutting is stressed it can take anywhere up too 6 weeks to root.
i usually cut mine, soak the rockwool in clone start, use a rooting powder and stick them in a humidity dome, i spray them with water every second day and leave all the vents closed until the roots start showing out the bottom then i open the vents. once the roots are plentiful and around 1- 1 1/2 inches out the rockwool them i transfer them to the 95 litre pots and thats where they live out their happy lives

Thanks Z! I will check out the vids and I have been very careful with how much I spray it. Just making sure the rockwool stays moist but not wet, and that the humidity stays above 80%

Hi Jason,

No I do not repeatedly check the cutting. Roots will show when they are healthy and ready for transplant so that is unnecessary. I only pulled the cutting once after a few weeks to check and seen nothing but my original black tip. Which in-turn the only "different thing" I've really tried is just pinching that tip off and sticking it back in a fresh rockwool cube. That and changing my lighting because the clone prior to this surgery was heat stressed. So far the new one has not shown any signs of heat stress.

I made a typo in my last post. I don't know why I said 18/6. I left it on 24 and only last night gave them a nap for a couple hours. It's doing well so far but have to wait now as its a "fresh cutting" so roots may not show for a few weeks. It looks healthier than it's ever been, however, so I'm hoping for the best.

That's basically the same thing I had going on here as well Jason, but for this second attempt there's no rooting powder so it will be interesting to see it root without that.

Thanks for dropping in! I appreciate all the input I get.
