New greenhouse

[nick the grief]

Hi DA,

I get my BW from NA Kays, they will sell it by the metre but I get a roll as I've two to line and iuse the large bubble sort - it cuts out less light - I leave it up all year round as well as it helps shade a bit in the summer by taking the glare out of the sun - you still need shading over some plants though and more importantly - it's a real pain in the 'arris to take it down

Love the GH btw I had a look the other night and one modification to the cold frame, Paint it inside with a good bright white gloss paint it will stop stuff getting drawn

I've used outdoor grade clear silicone sealant to keep my panels in as I have polycarbonate too. It also helps to stop water getting in the channels as when the algae grows inside these, there's no way of getting it out, unless you fancy pressure washing!

Hi Adreastea

How have you done it? Used W clips and then run silicone up part of the side of the panel. Damn thing keeps blowing out. Still using the washing line and some panel of wood to holds it in at the mo.

On my greenhouse, the polycarbonate sheets slot into the munting bars. I put sealant over ALL the joins where the sheets fit into the bars. I thought this would also help to stop any rain drips and draughts! I didn't get any W or other clips supplied so I made do with this method. I didn't smooth over the sealant but left it in quite a thick, generous layer. You can also use it to stick the sheets in, put on finials or stick other bits together if you so wish! If you decide to try it- hope it works
