i've been watching the spot at the on the east facing wall at top of the garden today. it's been abit cloudy this afternoon so it's been hard to tell exactly how long and how much light it gets but it appears to be roughly the following.

Morning till 11am : mostly shade, not 'Deep shade' but there is a shadow from the house where i would want to pop the green house.

At around 11am the sun came over the top of the house and flooded the area with pretty much direct sunlight till about 2pm.

By 2pm the sun had moves west over the wall so the area started to go back into 'Shade' by about 4pm i would say that 50% of the depth of the greenhouse would be in shade but i do think i any plants in the front of the greenhouse would continue to get direct light untill about 5-6pm.

I don't think the light was really dark, most of that area of the garden is reasonably bright there simply isn't direct sunlight for very long.

I suspect i won't grow veg all year around, it's more about prologing the season, starting off things from seeds and growing a few bits and bobs that like things abit warmer than our summers tend to allow without help.

Really though i'll grow whatever the conditions allow.
