  • 1.  Heating a greenhouse

    Posted 11-10-2022 10:45:00 AM
    Hello.  Our greenhouse does not stay warm enough to grow in winter.  How do others heat their grenhouse?  Anyone heating their greenhouse by connecting a compost?  I would love to learn more about this.

    Try passive heating with a compost pile!  I found this on YouTube.  https://www.youtube.com/watch?v=AjHIwabtqGo

    He doesn't do anything to mitigate the methane or ammonia produced.  That's not very safe to vent into the greenhouse.

    Try row covers, leaving pails of water inside and sealing any openings.

    What grow zone are you in and what are you trying to grow in there in the winter?  Often season extension is as much about plant choices as it is about creating microclimates :)

    We are in Southern NH.  We are looking to grow pollinator-friendly plants that we can transfer to the schoolyard, and just grow in general.  Definitely open to ideas.

    Meghan, I would look into plants that are native to NH. Those ones are the best for your region and helps to support our native pollinators (not just the lovely nonnative honeybee). Typically, these plants can even be planted in the fall or winter as they are adapted to those growing conditions, it also helps to stratify the seeds.  Check out your local university extension office for native plant guides. nh native perennials

    Hi Meghan, 

    The BEST pollinator plants are those that are native to your area. Here are some sites to help you.

    Megan,
    I use seedling heat mats to keep seedlings warm in the greenhouse when the evening temps are still dropping below freezing.  Also keeping everything well watered helps it from freezing. I would agree with the others that planting your local pollinator plants in the fall is best.  What we did last year is we planted many pollinator plants in pots and left them in the unheated greenhouse for the winter.  We had great germination this spring and transplanted them into the garden in April and May.  I'm in western Mass. I hope this helps.
    Hope
