Its working quite well. Ive had one not take out of about about 15. Have 3 going.
Its almost like cloning.
I cut the top part to a flat point. 1/4 to 3/8 long taper.
Split the bottom the same length. Apply some fresh allow to both.
Slide the top into the bottom and wrap with thread tape. The tape is the hard part. Very fiddly.
I then bag with a pre moistened sany ziplock bag. I slit the bag 1/4" on the edge at the end of the zip. Thats the hole for the stem, so the zip is vertical. I keep this hole below the graft point so if water drips it goes down and out and not into the wound.
Leave it on for a week or so, untill you can see the cut maintaining its own humidity. Im thinking this means nutrients and water are moving up into the cut and humidity can be reduced. I open the zip but leave the bag on for a few days. Then remove.
This is a great way of keeping many different strains on one plant. Plant counts suck.
This may be an excent way of flowering multiple strains as well.
Or it you have a great strain but the root system is lacking, graft it onto one with a superioir root stock.
Ill be running al least one in the greenhouse next summer that has a few different strains on one plant.
If your havimg nat problems, I should mention my container.
These are 1L containers. With a lid.
I cut a hole in the lid and lay polly wool down before i put the lid on. Nats hate it. They cant crawl through it so that prevents them from getting in the top. The bottom i drill a few holes inside if the bottom lip. I use white styrofoam as my shelf with a gutter routed out 1/2" in from the edge to take care of run off. Nice and flat. So that keps the nats out of the bottom. I also spray the wool with teetree oil every so often. Nats hate it to.
