I got some pics to show how I up-can. I cut landscape fabric in a circle then 1" to 2" cuts, then press into the pot. The cuts need a snip or two sometimes to fit right. Then I fill with soil and bury a pot, like they are in. I water really well, so the inner pot can come out nicely, then up-can.
So on MRS, it is Multiple Rooting Sites. Here is a post about it, but the guy I know doing it doesn't know who wrote it. So can't credit it.
"MRS stands for Multiple Rooting Sites
you will be basically creating a entirely stand alone rooting structure and feeding system for your plant which will supplement the plant in such a way as to allow it to constantly run with its nutrient uptake going full throttle 24/7 (this will also help with the metabolizing of micro nutes and allow more of them to enter the system also just by design)
all you have to do is break out your rooting hormone and your scissors and pick a bottom branch that is nice and fat and low hanging ... something that would normally make a killer clone
now we are going to sacrifice this future monster clone for the sake of the plant..
you take this branch and instead of clipping a few nodes back and then using it to clone ...you cut off the end of it creating the same 45 degree angle you would normally make on a clone and scar it the same as a clone also... just like its the end of a clone getting ready to put it in your clone box or growing medium
you will now have a branch with a clone end sticking out where the bud site would normally be...
now the same as cloning you need to wet it and dip it in rooting hormone ( powder .. gel ... whatever)
and you will want to take this butchered branch and put it at least a inch into the soil below the plant bending it down into the dirt and making sure it wont pop back out again
what you have just done was make a alternate rooting site for the plant and as soon as it takes hold in about a week or 10 days you will see a sudden burst of vigor out of your plant and you will want to cut your nutes back to half strength
this is the only drawback and one of the major money savers for the high priced nutrient buying crowd out there...
with twice the rooting zone now occupying the pot it is utilizing more of the soil mass and also pulling out locked out nutrients the original root structure couldn't hope of getting so it will fill the plants gas tanks up pretty quickly and will also utilize the new incoming nutrients on a much more efficient scale which makes for less nutes left in the soil ... less nutes needed to maintain the plant at peek... and a plant that is getting just as much as it can handle on a full time basis increasing yield to huge potential...
all i can say is try it ... buy all means prove me wrong if you can... i have been using this technique for about 2 years now since i thought it up in a stoned stupor one night while taking clones and it has not failed me yet"
This will be a good test. I trained 2 branches from each, so I can root them.
