Also, grafting is tricky to match scion to rootstock. If you start with a low producing less vigorous scion, then a high vigor rootstock seems to increase production the most. The converse is true with a highly vigorous scion, a generative rootstock makes the best crop.

Are you using double layer plastic for your greenhouse covering? I've seen it cut heating bills by 50%. You lose a bit of sunlight but gain so much on heating bills that it is worth it.

No reflective mulch as the plastic the coir is in is white and I don't want plastic on the floor as it's deadly when wet!
One of the reasons I did not graft this year is I am trialing so many new varieties. I need a year to see how they perform and what their growth characteristics are like. I will narrow down this years trials to the best of the best for next year and be able to choose the rootstock that best suits what I decide to grow.

Yes, the greenhouse is double poly that is inflated with a small fan for about 8-12 inches of dead air space between the layers. Not only does that insulate(ok, maybe not, it's just plastic!) but it also adds a tremendous amount of strength by being stretched so tight. The wind and snow don't damage it when it's inflated. A single layer will sag between bows and I have seen it collapse entire structures when the weight gets to be too much for the steel to carry.
