How green does/will my Garden Grow? Part IV

I'm starting to think this is going to be a bigger project than I first anticipated! The "plans" I found were for an 8x12 green house and I turned it into a 12x18  greenhouse. Now I am not a builder but I do like to build. I think because of this some of the things I've done well, it reminds me of when I sew something, I like to sew but I am not a seamstress like my Mom was she taught me really well but when I sew sometimes I need to rip things out and do them again. So now of the things I've been building I need to rip out too, thing is its not so easy to rip out boards! Luckily for this project I have been using nice long wood screws so its easy to back um out if I need to!
  My daughter and son in law came over tonight to have dinner we had one of her favorites tonight "Jack Daniels Salmon" with wild rice and fresh beans from the garden. Then they went out to help me with the greenhouse! I was so happy I didn't need to cut that 30 degree angle on the `12 foot 2x6's...:)  Course once they were cut I realized that the doors I made were wider than the angle of the board allowed plus it was going to make the top too flat so we decided to raise the ridge board up higher to make the angle steeper.  So we raised it up about 4 1/2 inches and I think now once I tack on the 1x6  to the ridge board I should be all set to start adding the 1/4 plywood ribs.

Now there is one small problem which is why I'm glad I used screws, the 2nd doorway from the left I didn't measure it right, the door is the right size alright but it sits 2 inches further over then the others ...ugh so tomorrow I will go unscrew it and recut the support boards and hitch it back up again...ripping out..I hate ripping out...but I want it to be right so I will add another day on to this job because of my mistake.  I think for fun I will tack on the 1 x6 to the ridge board though and then hitch on a  couple ribs just to be sure they are going to work!

I'm getting closer to having a greenhouse...:)
