unless you keep adiquate ventilation during the winter while useing the heater it is probable that it will melt

Sorry, Charlie, but that is cobblers! A polycarb greenhuse would probably suffer if Squiggle put a coke oven in there, but I don't think that's what she had in mind.

It depends entirely on what kind of heater you use, but electric ones come with a thermostat. Paraffin ones can also be had in quite small sizes, though I gave up on those back in the dark ages and, as Charlie says, the place needs especially good ventilation with those, because they create extra water. You can run a power cable into your greenhouse as long as it goes through an external RCD (circuit breaker) but obviously common sense needs to apply if you have kids etc.

In my winter greenhouse I have lots of bubble wrap insulation (which of course doesn't melt!) and so should anyone else who intends to heat a greenhouse over winter. Frankly, using an exterior cold frame too, I have noticed very little difference over the last few years between the heated and the unheated for 90% of the things I keep. Even quite tender stuff like canna lillies etc have been coming through fine in the cold frame. So think hard about what you want to heat and whether it is worth the added expense.
Depends where you live too though - I'm in sunny Somerset.

AFAIK the worst problem with polycarb greenhouses, apart from actually working out how to assemble them, is keeping the plastic glazing in during high winds. You could probably do a search on this on this site for specific answers & maybe a Google as well. There must be solutions people have found that work.

Polycarb is safer than glass and quite light, so do make sure you fix the thing to the earth once you've built it.

Good luck with the assembly bit!

Thanks for advice, im gonna pass on heating greenhouse this year but nice to know that i can do it in future thats if it hasnt blown away lol, my b/f is a sparky so ok with electrics.
I have searched on polycarbaonate greenhouse loads of bad reviews for them especially the gardmans, cant find a review on mine its palram silverline b&q sell them. I think im going to do what someone suggested and put clear silicone round all the panels then they shouldnt blow out also put slabs inside as they seem to be a lip on bottom so that should hold it down, even it only lasts a couple of years i will have had my money worth.
Bubble wrap think my b/f can get that from work, plus i presume that will help with shading in the summer too.

thanks again

You can't be old at heart Charlie; you've mastered this Internet thingy! And, anyway, it doesn't matter a bit - we aren't supposed to agree on everything here.
Let you into a secret; I'm on a pension too, which is why I have time to cause trouble!:rotfl:

Having recently "helped" my husband build me Polycarb Greenhouse I have devised a 7 point plan which you should find useful when erecting it.

1. Allow at least 120 hours longer than it says you need in the instructions.
2. Have a Japanese to English dictionary to hand
3. Gin at an early stage can take the edge off the pain.
4. A magnifying glass is useful for deciphering the numbered parts as there are crucial differences between part HC-104568888999A/x* and HC-104568888999A/z*
5. Drink more Gin
6. remove all sharp implements from everyone's reach.
7. Have a good divorce lawyer on speed dial. :cool:

It's like childbirth though. As soon as it's finished you forget how painful it was and just sit admiring ythe fruit of your labour.

OMG can't comment on the childbirth bit, but the rest is dead on. I bought a good make of greenhouse and it still was a pain to get up, I was just suprised at the sheer amount of work needed, even getting the window rubbers in, took two of us a good half day. That was a glazed greenhouse though.

8. Read ALL the instructions first (at least 8 times), before touching any parts.
9. If its a glazed greenhouse, check, measure, check, measure, then do it again.
10. Do take the gin seriously.

Due to the awful weather we've had and me being miserable as I couldn't be out in the garden I'm under orders from dearest OH to get a bigger greenhouse (think he wants to get rid of me!!;) ).
Looking at something about 8x14 or so and got about £1500 to spend.
Needs to have safety glass and preferably be green instead of plan aluminium.
In South Wales if that makes a difference.
Any suggestions lovely people?
