I'm also revegging my best plant from the last harvest, primarily because I wanted to guarantee a continuation of the phenotype.
Mine was in a DWC and, after harvest, I just popped it, net pot and all, into a larger pot with clay pebbles and then into a top feed recirculating system. New growth appeared after only nine days and she went crazy. Once the new growth was well established I took her out of the net pot and chopped most of the roots off and repotted her in the larger pot and she didn't even bat an eyelid.
I also tried cloning some of the smaller buds but only ended up with two clones taking root out of 10. One of them started throwing out new growth about a week after the mother, but only sent out one growing shoot that split into two tips, like a plant topped at the first node and the growth has been very slow. The other bud clone only started revegging about 10 days later, but it looks like there will be more shoots than the other.
I took 8 cuttings from the revegged mother the other day for the next crop and you can barely notice - the growth is still dense and very vigorous.
Here are some blurple pics to show how they're doing with the reveg mother dominating the pics.
The first bud to start revegging can be seen at the bottom front here
and the other one is front centre here, but it is so small that you can't even see the growth
The two back plants, centre and right, are clones of the same age - the one on the left in DWC and the other in soil. I'm amazed that the one in soil is far outpacing all the others. I chose to have one in soil to compare soil against DWC for both growth and bud development and also because I had no space in the DWC nor spare pump to do another top feed.
