Busy day in the greenhouse

Hard at work today preparing my peat for planting my exhibition seed potatoes. I put my peat through a shredder and add 16oz of Vitax Q4 qnd 12oz of calcified seaweed to the mix as it comes out of the shredder. I have 17litre polypots that I fill with this mixture and I use a white marker pen to write the name of the variety on the bag. I leave the mix for a week then I put my chitted potatoes into the bags. I leave just the 2 strongest chits on the potato and remove all the rose end chits with a sharp knife.
I hope to make it to a few shows this year and have a small display of potatoes for people to view. Does anyone else grow to show?
