is it possible to grow flower seeds in a plastic greenhouse. thanks


  • When it stops blowing😁 and gets a bit warmer in March/April maybe if you use a tray with a clear lid to help heat it up, otherwise start inside and then put them out after sprouting. 🙂
  • Firstly you can do this then put them out after sprouting

    I've tried before with poor results, hard to stabilise temperature and water efficiently. Better to start on window sills then use the plastic greenhouse to harden off.

    It largely depends on what you're trying to grow. 
    The biggest problem with the plastic greenhouses is that they really only offer protection from the worst of the weather, as they don't have the same substance as a glass one. They're useful for things like starting off hardy annuals, but the downside [apart from keeping them where you want them  ;) ] is that the temps inside fluctuate a lot more, as @nickten says, so it's vital to keep them opened/closed consistently for good ventilation.

    I used mine mainly for tomatoes, as they don't do well outdoors here, but also for overwintering small, vulnerable plants, or my rosemary,  or starting sweet peas/lettuce etc  in early spring, but that's about all. The covers tear quite easily. I got a more substantial little growhouse which has polycarbonate panels, and that works much better.  
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...
