thanks for both of your replies and warm welcome!

it's true, the garage will stop the sun in that spot until around 11/12 o'clock, and then, all through the day, the side closest to the fence, will be in some shade.

i read somewhere earlier, that this can be compensated by using that side for the staging / potting up area.

I'm thinking the angle of the sun will reach the side furthest from the fence, but you're right, this will only be for a few months in the middle of the year.

Unfortunately its the ideal place, but it may have to be accomodated elsewhere!

It is a polycarb greenhouse, so the opacity of it should let in 20% less light than glass ... great at the height of the summer, but perhaps not in spring/autumn and behind a fence!

Thanks
