easy to use air layering Pots from the store - good idea?

Hi all,

I haven't seen a post of these pots before but on first view it seems to be a good idea.

Bit pricey so in my permie and recycler head is already a plan how to make an "original Copy" of these nice little pots.

They really look like they will make air layering very easy, fill both half shells gentle with dirt, close the shells and so you are sure that the dirt applies even pressure on the area.

Check yourself and say yeah or nay.

That looks like an improvement over the product I've been using.

I find that these need to be close to vertical in order to hold water and that is not always easy. I've never tried the plastic bag method but I think it would be worthwhile. Since learning (still learning) to propagate from cuttings, I've been doing that almost exclusively.

I have been meaning to post on this topic but did not get the pictures taken so procrastinated.  I used the ones in the second post. Looks  like the ones in the first post could be make from fruit separator trays cut in strips and then pairs and then folded and stapled into clamshells.
On to my success story. I used them to air layer the side shoots on my indeterminant tomatoes. As mentioned they need to be tied or taped to the tomato cage to keep them vertical. After a week they had a good foot ball and could be cut off and transplanted. because the side shoot was already in bloom it went right into fruit production. by end of season produced as much as the mother plant
