I got the green trimmed 6 by 8.  It took me about 8 hours to assemble this over two days.  I was working at a slow pace and half drunk most of the time.  Two people could knock it out in half the time.  Tip: When building make sure ground is level.  Despite time invested into building I'm extremely pleased with this greenhouse overall.  It looks like it will last a few years with care.  Five stars.
