Now cleared out the bamboo (see Bamboo..yuck) and am going to order the tunnel at last.
Now realistically I can`t see us getting the frame in place for quite a few weeks yet. Order..delivery and finding some help to assist with putting up the frame and of course the weather.
The question is, would the best thing to do once the frame is in place, to just get some manure in the ground....(.didn`t find one worm when clearing out the bamboo, soil seems lifeless)...then plant some green manure to overwinter and then look to putting on the polycover
 in the spring?

If this greenhouse is for actual crops, then I'd say YES! Much easier to add stuff without the walls up and possibly damaged from spading in stuff. It'll give the manure time to settle in and be ready for spring growth. Sounds like your soil is short of useless from the bamboo so I'd add as much of other stuff as I could: coir, old growbag contents, shredded leaves, compost, etc. anything that will help with the humus and moisture retention. Or if you're green manuring, it's also easier to turn under in spring without the walls up. But still add what you can.

Thanks Trillium....going along with what I thought.
