Nice work on the interface - a game like this lives and dies on UI and yours conveys a lot of info in a pretty clear way. It's a shame there's no completed gameplay loop yet as it means there's little motivation to design the perfect garden (unless I missed it, which is totally possible).
Respect for turning up the seasonal variation to 1000% so that in winter you're gardening through a blanket of snow and in summer you're gardening on the surface of the sun
