I had a “suggestion” pop up on my IG feed, and it showed a clone in one of those quart-sized containers that you’d get HotNSour soup in from your local chinese restaurant.
It was actually a clone that was being grown in a gel, like agar, in the bottom of the container. Aside from the agar, it seems like the soup container might be the ideal means of providing a solid humid environment for the clone while the roots are forming. I think the agar medium goes way beyond what most of us are going to do at home, but wouldn’t a cube of rockwool work just as well?
Take the cutting, dip it in gel, place it in rockwool, and put the whole thing in the container. Spritz it down so it’s good and wet, and snap the top on. Maybe a few holes in the lid, just to let air in/out. Check it every few days, and spray as necessary.
Would this work? Anyone done this?

I saw the same ad 
I do this with my Anthurium plants in a Grillo’s pickle tub instead with spanghum moss. Interested in trying Agar or even a hydroponic medium like rockwool that you suggested.
trying it now with some windowsill peppers seedlings with coco layer at the bottom. I don’t see why it wouldn’t work.
Some, and Im gonna start doing this myself, just stick them in a ziplock freezer bag. From what ive seen, it seems to work well. But, I cant see why that wouldnt work too.
I have 20 or so clones rooting now in a similar way. Cut in a rooting plug, drop it in a solo cup, two solo cups into a large Ziploc, pour some water in the bag, put cups in, and zip the bag up. After a week I just start to slide the bag open. Didn’t have room for a tray or two, so did this to fit them under the canopy.

I have a big block of coir downstairs that I haven’t soaked yet.
I’m thinking that would work in the solo cups and the ziplock.
Thanks for sharing. They do make some larger ziplocs for marinating, I think they’re 1.5gal. On my way to the store now to grab some.

Works fantastic for a small number of clones. Easier for them to keep the humidity up in a smaller space than a full size tray. I do not spray them at all. The space inside the container is small enough that they keep the humidity high through their own transpiration. A small amount of water in the bottom of the container has worked perfectly. Fully close the lid for the first few days, then you can just let it sit loosely on top until they root.

Heh, you’re where I saw it, and was like “yep, stealing that idea”. Did see you say you saw it somewhere else.

@FirstCavApache64 does it in a similar way.

The only thing I do differently is put a moist folded up paper towel in the bottom of the cup against the side of the cup to keep moisture up and draw out the roots. A member on RIU showed it to me a few years ago and it’s great for a small number of clones.

So you take a cutting, put it in a Solo cup with a piece of paper towel? No other medium like coir or rockwool?
Then put that in a ziploc?

No, I take a cutting, dip in Hormex #8 rooting powder then place it in a Root Riot plug. The cutting and plug are placed in the solo cup and the paper towel is up against the side of the cup. I spray the inside of the ziploc for the extra humidity and then add the ziploc bag. After a week I put some small holes in the bag to reduce humidity and start checking for roots.
The arrow in this pic shows the folded up towel position on the side of the cup.
Most cuts root in 10-14 days and look like this before planting.
