Hello Jools, Hello Weavie, great to see your enthusiam. Hope your greenhouse does magic for you. I grew some squash this year and very excellent they were. See the pic.

I grew poatatoes in buckets which were wonderful. They were never in the greenhouse. I kept a note of the dates I planted things so I could learn from it for this year.
I posted pics of some of my sucesses at the time, but if you're interested I can repost them. Good luck with all your plans.
