Thanks for the review

A couple of suggestions. One whole wall of work bench. Great for storage underneath and small seed trays and propagation area. Self opening vents. No power required as done with wax and cools in summer and shuts themselves at night. Bout $50. Not sure if it had spouting built in but barrel storage for water is great at one end. You can get solar light and air vent cheap also. Keeping warm in winter is trickier. Without power mass is required. I’d put a row of hay bails around edge that doesn’t have shelf and put pots and trays on this. It will definitely help a few degrees as they absorb heat and release slower at night. Anyway looks like you are on your way!👍 nice
