That you never started, changing the soil in one of the GH got down a foot and then solid clay

I find digging greenhouse soil out really difficult, it is the sort of twisting and turning to empty the spade without demolishing the glass! demoralising to then find clay :BangHead:
I found some asbestos sheets about a foot down so leave them and just add most compost/manure each year
Couple of days graft soil in shelving up and ready to go

That's quite a transformation in greenhouse 1. Beautiful dark, crumbly soil with a fine tilth. It just makes me want to lift up a big handful and smell it! Good job well done Davy!
Can't you build up the soil level or even put in a raised bed to give yourself more soil depth? Would be easier to change when the time came. I don't have an open soil border; in my GH, couldn't be doing with it after trying it the 1st year. Used pots or grow bags for a while until I found Marshalls' Grobeds, which are sort of a cross between raised beds and bags that just sit on any flat surface. Get great results from them.
Hope this helps.
