Hi gang,

I am about to erect a Rhino 8x10 greenhouse in the veg garden. *The
only plot available is on soil (no hardstanding available). *I am not
sure whether it is worth digging and concreting a full foundation as
per a house or whether I should just use the four concrete block
system to anchor it down. I would welcome any tips/pros and cons about
this job and the erection process in general.

Cheers,

If you don't have a firm base the frame will bend and twist, as the
soil heaves and swells and shrinks. the door will stick, and some of
the glass might crack.
