greenhouse insulation

what is the best way to insulate my greenhouse?

and how do i put it in/on?

thanks

 

I tried bubble wrap held in place with plastic twist locks in my Aluminium house but it wasn't very good,no way to fit it on the door or vent for a start. So I dabbed the glass with clear silicone and stuck the wrap straight on to it. I left it on all year round and it helps keep it cool too.

 

I have fixed my bubble wrap with plastic twist locks and for the corners I have used Duct Tape (get the 50m rolls as they are much cheaper than the 2m rolls sold in supermarkets. �£4.99 for 50m as against �£1.99 for 5m).

I have also used Duct Tape for padding the glass when reglazing. The old plastic tubing was useless so I placed Duct Tape on the glass where the clips go, five thicknesses on the back and one on the front. The greenhouse is thirty years old. I am lucky, a friend has given me his greenhouse for nothing. All I have to do is to dismantle, transport it about three miles and re-assemble.

 

Larkshall, you do know you can get corner Alliplugs to make life easy?

 

Those are the ones I used on the Internediate bars but theres no channel in the corners so I have to fasten with Duct Tape to the corner angles.

 

One advantage of a wooden framed GH is that drawing pins are a pretty easy way of holding bubble wrap in place. Murder on the thumbs putting them in though and after a few years it starts to look like the GH has woodworm :D

 

Hiya everyone, I'm new to these parts.
I've just bought an electric fan heater and heated propogator for my greenhouse, figured the weather will warm up soon and it isn't worth messing with the bubblewrap. I use a three tier mini greenhouse for night time and just put the heater on low to keep it just above 0c. What do you all think? my plants are slow in taking off, I've got petunias, menopsis, geraniums, sweet peas and fuschias I've taken from cuttings. Should i up the heat and insulate? any advice to a newb greenhouse grower would be appreciated. Nice to meet you all,
Rose

 

Garden Guru, have a look at Scotkat greenhouse,its terrific

 

Oh mine my smaller greenhouse is every so cosy now that my dear H put in heat for my and even now got a light.

My larger greenhouse is unheated

 

Rose, I would try and keep the night temperature at least 6/7c to keep the plants growing when young, it is difficult growing plants needing different growing temperatures some (petunias) can be grown cool some (geraniums) warm.
I have this problem on a HUGE scale at work and getting the balance so that everything grows is not easy. Bubblewrap is good for shading.

 

Hi and many thanks for your reply strongylodon. Will try to keep the temp at 6 or 7 as you recomend. The petunias are doing well which proves you know your stuff! It also explains why the geraniums are somewhat slower. Will have to experiment to try and please them all, once more thanks for the tips

I checked temp in my greenhouse which have bubble wrap and thermastic heater and it was 10degC and plants are looking good.

 

hi there i just got a new greenhouse its polycarbonate my last one was glass but the wind got the better of it what i want to know is do i still put shading in it as i've heard they dont get as hot as glass ones?

 

Hi Kazy let me ask do you have defused sheets on the roof?.If you do you will notmneed shading.
