I am trying my first attempt at grafting. Using maxifort rootstock to graft to heirlooms. A friend and I are attempting a greenhouse for early harvest and the soil is mucky so we are doing it in grow bags and know of a grower that had crop failure trying to grow heirlooms in greenhouse conditions but pulls of a fine crop using maxifort.
Here is a picture of our first attempt at grafting, can update my progress as we will be growing plants with and without grafting.

BTW, that video of the grafting machine IS amazing. Our grafting adventure went a little slower then that.
