Nothing to report yet, as I said in my first post it takes forever and is worse than watching sod grow. All of the roots look healthy, the bubbler roots are crisp.
.
I'm running another root experiment and although it has nothing to do with cloning, I though some of your might find it interesting. I'm converting my 5 gallon buckets into air pruning pots, my first design is below and I'm building the 2.0 version tonight - using a jig saw to cut out most of the middle of the bucket (leaving 3 or 4 vertical strips of bucket sides) and fitting in a rigid metal screen (1"x1" holes) like is used in scrog. I'll line the metal screen with the fiberglass screen from above to keep the mix in, probably double wrap the screen. I'll post some pics in the Air Pruning Pot thread later, I'll keep this thread for root cloning as much as possible.

I've been thinking a lot about developing a better root system, looking for bigger yields and perhaps better potency and quicker harvests. There are several commercial choices from porcipine like hard plastic wraps
to soft bags
or a chemical paint, like Spin-Out, for the inside of the pots.
.
I need a rigid bucket for low stress training, and I have a couple dozen 5 gallon buckets that I'd like to convert.
.
1. Drill a 1/2" hole every 1" center. Drill a 1/4" hole between the 1/2" holes. I put pro mix in the bucket to make it more rigid and the drilling was much easier.
.
2. I lined the bucket with fiberglass screen to keep the Pro Mix from falling out of the holes.
.
The plant goes into veg for 2 weeks under a 150W HPS, I'll train the plant a bit each day and in two or three days the two stems will be bent in semi circles. Then I'll train the branches to grow up and it's a nice scrog style grow.
.
I'll follow this plant through flower to see if it performs better than usual, after I harvest I'll check the root system. And post pictures of both.
