DIY Coffee Can Cloner
@Rootsruler
I’ve used old red Folgers coffee cans for years. Great for old paint or garden uses.
I started using them in the tents to hold water in front of my intake fans to add humidity. Not long after I started tossing trimmed branches in the water just to see what would happen.
Over the summer I started getting roots in just two weeks. No lid, no hormones, no scraping or preparation. This was in the veg tent just under the canopy. No brown spots or yellow.
In late fall I added a lid with a hole to make things darker. Not sure it helped but didn’t hurt either. I usually change the water every week to two weeks. Keeping the water about an inch or two from the top.
These are from 2 weeks ago. To much light even at lowest setting. Photos are from Wednesday.
This was Thursday after I planted the one with the most roots.

So I made a cheesy cloner yesterday as an experiment.





I usually don’t use plugs but tried them once or twice before. You just need to cut or melt a side channel all the way into the middle, just big enough to slide the stem out later.
I’m looking for a better spongy material that’s thicker. More like a pool noodle. I’m thinking the white packing foam that comes with things like TVs, but not styrofoam.
Hope this helps someone or gives them a better idea.
