Hi everyone,
I have a small plastic greenhouse and it often gets to 30* and am wondering what temp is ideal and at what temp do I need to open it up to cool it down ?

Many thanks


What have you got in there flowergirl? If it's something you're going to plant out eventually I'd start opening up in the day time


I have herb seedlings and flower seedlings and some brocilli that I have grown from seed they are about 3 inches tall now.

I have opened it up on the odd occassion that it has been sunny  as it was above 30* and I was worried it was getting too ot in there


That's on the hot side for seedlings, flowergirl. Leave it open on sunny days. You might even find you need to move things outside. Even ventilated the plastic traps and intensifies the heat.


Thanks all for your advice....
