I found the greenhouse (a very small one) to be disappointing and frustrating last year, but it was my own fault for not learning more about it before diving right in, as I so often do. I ended up killing my seedlings because I didn't water them enough. I wrongly assumed they'd naturally stay damp longer with all of that condensation all over the walls of it, without connecting the dots that the condensation was the water being sucked out of the plants from all that heat in there. Great learning experience and I'll know how to proceed a bit better next year. Dealing with plant life of any sort is deeply therapeutic for my being, once I learned to better navigate the frustrations known as life via my breath and my consumption habits.
