Unheated Greenhouse

[Teen]

Hi All

I'd love some advice if you can give it.  I have one of those half greenhouse, half shed type things and I do mainly use it for growing veggies etc.  I have a lot of seedlings in my house at the moment including tomatoes and to tell you the truth they're taking up a lot of room but I'm terrified to put them out in the shed in case I kill them.

Do you think I would be safe to put them in there?  Its very warm during the day but at night I'm guessing the opposite.  Any advice is gratefully appreciated as usual.  Still new to this side of things.

Hi Teen, my advice is to get yourself one of those min/max thermometers and put it in the shed/greenhouse.
Then you can see what the temperatures are like by night & day.
Also watch the weather forecasts, and you can give extra protection ie covers/fleece/bubble wrap etc.

Mine are out in an unheated greenhouse, but under fleece at night.

I'll probably be shouted down for this.. but as a newbie who has seedlings bl@@dy everywhere and not a lot of space... I will be buying more plug plants next year!

There is something slightly exciting and infuriating about growing stuff from seed.  It feels such an achievement when a little plant pops up from nothing.  I won't shout you down

Whatever suits... if you were nearer you could buy from me or Manics at the plant sales. I have access to four greenhouses, one obscenely large but still manage to fill it before the sale with potting on...

i bet you dont! once you reap all the rewards of all your hard work i bet you have even more seedlings all over the house next year!

My problem is I'm not getting enough sun.  That's why I considered moving my seedlings into my shed.  I'm just afraid it could be a fatal mistake with the temperatures still dropping at night.

If it's a half wooden affair, it should maintain temps above freezing at this time of year, get a max / min thermometer to find out. you can fleece for extra protection at night if needed, rgds, tony

Go for it, I have peppers and chillies in mine, will be putting toms in tomorrow.

I've been putting propagator lids (the cheap Wilko ones) over them at night.

Mine were started in January and are growing fine in an unheated greenhouse on the plot. I did use fleece when it got to -5 earlier but at the moment the plants seem to be happy naked.

The protection from the wind makes a lot of difference in it's self. That can cause more harm than anything.

If it gets sunny during the day you will have to water but if it is a dull day you may not need to.

I have got some very tender plants in there too. Tomatoes, peppers and house plants cuttings.

If you are wary, keep a plant or two at home or just take the most hardy like leeks and sprouts to start with.

Perhaps I'll be brave and put them out.  They would get more heat and light during the day in my potting shed.  I do have those cheap wilkos lids and some fleece so perhaps I could use those if I think its going to get very cold at night.

I've got some peppers out there already and they're ok.  I guess that should be my indicator.

Thanks for all your advice.
