Me Jealous. You bet. Looks good to my eye. My one suggestion is go big or stay home on the fan and ventilation arrangements, especially for our favorite plant. I would make one or two sides roll up like the commercial greenhouses to let the wind blow through when needed. Mould is a huge issue with lots of plants in a greenhouse.
A couple years back a friend of mine asked me if I would check plants in his friend's greenhouse for him to let him know if they were ready. The guy with the greenhouse had been gifted a pile of seeds which to give him credit, he had successfully grown about twenty or so to late flowering. The greenhouse was maybe thirty feet or so by 15, as in big. No fan vent, hardly any large openings other than the door, and the entire ceiling and walls were streaming with water. The entire crop was already rotten. He ended up spending a few hours trying to salvage a bit of bud, but ended up putting the rest in garbage bags and inviting the seed donator to fill his boots. Twenty or so plants, maybe a half dozen doobies if that, and I would not have vaped a bud of it.
Think ventilation, lots of it.
