Root Spikes!
I see that a lot too in my T48 where you get roots growing in inside the collar, but I usually have them lower down too. Could be that the high temps killed off those and left the ones in the collar that didn't get as warm.
Good news either!
There are several others with roots in the collar, too. The one pictured above is still the most developed. Only one other looked like it had some "funk" on the roots.
I didn't have much time, so I gave them a short bath in an H2O2 solution, but didn't trim anything (yet!), then added some more H2O2 and DM Zone to the res.
I also adjusted all the clones to sit as low in the inserts as possible so the maximum amount of roots were exposed below the inserts, but it still isn't much!
Good job! I usually like to leave about 2-3 inches below the collar. Makes it easier to plant them when they are ready to come out. The other thing I wanted to suggest is to not let them go too far! I usually plant in soil when those root spikes are about 3 inches long. If you wait till there are a bunch of those little tendrils, there is more to get damaged when you transplant. You can refer to my journal and my T48 Start to Finish thread for photos.
Sounds good! I've found that the root SPIKES are a lot stronger and thus can handle the transplant without any chance of breaking them off or bunching them up in the soil. I always sprinkle a little Coco on the roots before planting so they have a good coating around then, and then hold them in the air in the hole and use a kitchen spoon to shovel the soil into the hole and around the stem until it stands on its own.
I find that they show an immediate response to the soil and start growing pretty quickly. Oh! I always float them in a B1 solution as I am preparing the pot. Just let them float around in their collars like little palm trees on an island!
Mr K, you could try "trimming a cone" into the bottom of the insert so the stem has more length exposed to the spray. Just use a razor knife or sharp scissors. You won't need much support for a small clone, maybe 1/8 " of neoprene remaining?
Ooo! Don't like seeing that black stem rot on those stems! Hopefully the plants can shake that off and continue rooting. Thats what happens when the temps get too high.
That is exactly how the 17 failed BC clones looked when I tossed them into the garbage can. They had no roots at all though, so at least yours still have a chance!
I would suggest cutting the black part off as much as possible and just leave the rooted section. Otherwise that rot is going to spread and kill the clone. Black stem rot is an insidious fungus.
Hello mr Krip sorry to hear about your high temps happens to the best of use natural complications not easy to handle!
Question for you do you score up the stem of your clone or just cut her at an angle ?
I only usaly cut at an angle but have been told to scrap a blade up the stem to remove the epidermis wall to expose some of the cortex this can halve root time. I am yet to try this but will be on my next set of cuttings.
I don't think at this point it would be worth risking pulling them out. Just keep your fingers crossed that the rot doesn't spread. It should have a tougher time surviving in soil as opposed to the nutrient rich waters of the T24!
As far as controlling the temps of the cloner, a couple of suggestions...
Fill several personal sized drinking water bottles with water and freeze them. Then drop one of those in the reservoir to help lower the water temp. You don't want to be putting ice cubes in there cause it will dilute your cloning broth and also possibly change the pH! You're going to need more ice than that to do the job fast and effectively anyway.
Another thing I suggest is putting a mini box fan or some fan to the side of or directly under the cloner pointing up at the bottom of the unit and blowing air at it. This also helps to lower the internal water temp.
Did you get your Polder probe yet? Never heard if you picked up some of those suction cup clips I linked to. They make the best clamps to hold the probe in the water and the suction cups keep it firmly in place underwater. Mine always stay put through the entire session and never come loose.
