The site clearing is taking a lot longer than expected. We have an infestation of honeysuckle, privet, and poison ivy.
We did decide on the 14'x16' GothicPro Premium. The site would not work for the 16'x20' and would have required extensive back fill. Also we want the greenhouse to be fun and not a chore. We felt like going too big would make us end up hating it.
We are still debating the base (limestone vs concrete). This will be our forever site so we want to get it right. We do know that we are going to put in a base foundation of minimum 2' to lift the peak height. We may go 3' by digging down into the site.
Here are more boring pictures of yard clearing.
On a side note about purchasing, Farmtek offers financing so we are looking at their 2 year zero percent interest deal. That is a really sweet deal.
