Hi all

I have a good amount of unused space at a side passage at my house

it only gets sun until about 11am - 12midday

I fancied putting rows of purpose built long boxes
on wall brackets on top of each other
(like a shelving arrangement)

what would grow well, considering the amount of shade?
how deep for the boxes?
I was going to sheet them with clear plastic (like a cold frame) is this
necessary

i fancy salad greens, pak choi, spring o's, herbs, shallots, garlic
tomatoes (probably need more sun)

any links welcome also

thanks in advance
