I have been gardening in a small (10 X 6')polycarbonate kit greenhouse for a couple of years. I have a heater and programmable thermostat and am wondering what would be an ideal heating protocol (i.e. temp for day, eve, night, etc.) I am looking for a protocol that would accomodate the widest range of flowering plants. My interests are mostly in carefree varieties that we are able to grow as annuals in the PNW summer. I am hoping to be able to extend some flower gardening into the winter this year. Lighting is another issue I am working on of course. Our winters are usually mild here. If I could find a way to get my morning glories to flower during the winter, I would be in heaven. Also, any recommendations of plants/flowers that would be good for a semi-beginner greenhouse gardener would be most welcome. I am just looking to dabble and create a little garden oasis to escape to in the winter. Thanks in advance for any suggestions.
