planting seeds in unheated greenhouse

is it ok to plant now even though the night time temperatures are only 3/4 c

 

I have loads of seeds now growing in an unheated greenhouse, so yes it does work.:thumb:

 

So have I :thumb: I just put fleece over them early evening time.

 

I have toms, chilli and peppers growing very well in my unheated greenhouse:thumb:

 

I have tomatoes about 9" high in the greenhouse. I shall have to go out now and plug in the fan heaters (set to frost free or just above). We had hail today, so it's a very sure sign of frost in the early morning.

If you don't have electricity laid on the you could use a hurricane lamp or two to keep the frost at bay.

 

All my seeds are coming through now but my greenhouse is insulated with bubble wrap. Its still warm in there all the way through the night. Ive got a few strawberry plants in there that i was given last year and they are starting to fruit already, i only re-potted them about 2 weeks ago and they have really come on. My beans have shot up over night.

 

Are you talking about sowing seeds or planting out young plants?
Seeds will be fine but you'll need to keep them well watered as they'll dry out quickly on sunny days.
Tomato plants should be fine, I've had them in the greenhouse and polytunnel for a week now and have also had butternut squash and peppers out too. The only thing I've not put out yet are cucumbers, but I'll be putting these out early next week.

 

things are starting to grow at last but very slow,perhaps due to low temps?
