If I'm concreting in the feet of my 10'x 6' greenhouse, how big do the concrete feet need to be, in SE England where we rarely get frost and the soil is pretty free draining into chalk? Advice I've had so far varies from digging 36" deep (!), to someone saying they should be 'about the size of a brick'. I've even read one comment that said the glass is so heavy, I won't need feet. Also, my base has 10x 8mm holes which could be used to attach, so should I be making 10 little feet, or maybe only 4 bigger ones? The holes are not on the corners, and there are no corner spikes.
