greenhouse ???

So they are all Agapanthus then...the more upright single ones must be young,right?because I have some given to me by Fran and they look like yours in the back row.
I'll post a pic tomorrow because I'm having a 'day for the Queen'

 

John, the " silicon " you bought from the �£ shop was probably mastic which isn`t suitable for outdoor use. Re the greenhouse it doesn`t matter if it is slightly off, it won`t affect it`s usefulness.

 

Can I just say that I find its best if you dont seal the overlap in the glass.
It allows the condensation to escape to the outside.

Probably painters caulk if it was only a pound a tube John.

 

The two at the front are adopted but what are they..A Lily maybe?

 

The smaller one looks like aspidistra.

Thanks for the advice David and Pete. I think you are right about mastic David. It just said 'Kitchen and bathroom sealant' on the label. So I assumed it was silicon. Actually I went out for a drink the other day and a young lady came into the pub. Maybe I should have asked her. I'm sure she was an expert on silicon. :confused:

 

Maybe the bigger one too Pal. Are they the same?

 

I'm positive they are the same...both a mystery :D

A recent product in the industry is a water based 'Kitchen and Bathroom'sealant but it's not intended to be used where it has constant exposure to water :rolleyes: I use high modulus,anti fungicide silicone which is easy to apply and dress and has no limits as to use,inside or out.

 

Thanks Nick. I'll try to get some but, on Pete's advice, I won't seal every crack, but I do have a good venting system. Mrs Sarra now sleeps in the g.house with instructions to open the vents if it gets either too warm or humid.

They are almost certainly aspidistra which (because of our Victorian ancestors) most people think is only a house plant. Actually it is very hardy. my sister has a large clump in her garden.

 

Sorry. I'm very tired (no not martini type tired) did you say that this water based kitchen and bathroom sealant can't stand constant water, like I have in my bathroom and, um, kitchen? No wonder its �£1 it should be 1p.

 

Agree! :D

 

Nick, I agree with aspidistra. John, as far as ventilation goes, if you used toughened glass or twin walled polycarbonate, with which to glaze your greenhouse, the odds are that you would have been using full size sheets.Which is just like you sealing the overlap. As far as the vent`s are concerned, you can buy automatic openers for about �£15 to �£20. So Mrs Sarra can have a decent nights kip. :D

 

Actually David, in view of my image, and all things considered, um ,um.

Mrs. Sarra actually sleeps in the kennel as she always has done, whilst Ed, the staffie, shares my bed.

Well she did say 'Sleep with you? I'd rather sleep with the dog.' But I grabbed that.

I've got automatic openers. They can open a bottle of martini before it explodes.

Never mind. Very soon I can drop these stupid jokes and we can actually talk plants (and greenhouses) again. Thanks guys,

 

Toughened glass and polycarbonate, nasty modern ideas David.
I have replaced one side of my greehouse glass with twinwall polycarbonate, and although it does give a bit of thermal protection, (it doesn't get frosted as quickly as the glass) it does drip condensation.
Something that tends not to happen with the glass due to the water running down, and capillary action drawing it through the gap.
The gap is mostly filled with water anyway, so you dont actually get a draught through it.

 

Oh. I'm serious again.

Actually Pete I did get upset a few days ago when I thought a piece of my glass had cracked. Then I realised it was water sitting between the two sheets, I hate polycarbonate which goes yellow very quickly and changes light transmission. Yet another agreement Pete.

As I mentioned my old Dad was a pro gardener and very good at his job (I think he did the hanging gardens of Babylon). He had to keep his boss happy for 30 years rather than until his bill was paid.

I like his view that a greenhouse is a GLASS house. Cos that works best.

 

But, if you have young children ( or boisterous dogs ) you have to consider the safety angle. And that, Im afraid, is toughened glass and polycarbonate.
