Greenhouse Shading

The sun has been quite strong over recent days, so I thought I would open this thread to remind those who may be new to growing under glass to remember to shade their glass.......after a very short time the magnified rays of the sun can do a lot of damage to your plants.

'Coolglass' seems to be a popular choice for some. This is very cheap and bought as a white powder, mixed with water before being applied to the glass with a sponge or paint brush.

I prefer green mesh netting myself, as 'Coolglass' can be difficult to remove when no longer required.

    David, I agree it can be a so and so to remove, also if the weather changes and we need maximum light in GH netting can be removed.

  • Thanks, KEF....I have used garden fleece before now, located (as with green mesh netting) on the inside of the greenhouse.

    Already queries have been posted which seem to be related to sun scorch......I had wondered if Orchid Lady had remembered too.

    Hello David K, I have never had to use shading before as I haven't really grown that much but this year is different.  I was wondering when I should start using it so thank you image

    When you say green netting, do you mean the type that can also be used outside to protect plants with little holes in?

    At the moment I'm monitoring the light level because it seems that one side if the GH doesn't actually get that much direct sunlight because if our big privet hedge and the other side only gets it in the morning, but will keep monitoring.

    Then there's the question of how to attach it?

    I'm going to consult my new (borrowed) gardening bible now to see what AT says about it image

     Hello O/L , my shading fits on the inside with plastic lugs , very easy to fit and purchased at B/Q , I also use some greenhouse nuts to secure the tops and edges

    it goes on the roof and down half of the sides , I don't bother with front or rear but it would depend on the position of the greenhouse to the sun

    I have an automatic window opener and to compensate for that I just have it a bit loose over that bit

    just thought my greenhouse is aluminium frame ,not sure what you would do if wooden

    best of luck image

    Hi GWRS, mine is aluminium too and I have some of those GH nuts so will use them, is it just the green garden netting you use?

    I have just been in my GH and I think it will need some shading.

    OL it is different to netting bit like a ...I don't know how to describe..Google GH shading image Doesn't sound like you need it yet. But good to be prepared. Like David I have strung fleece inside at certain times of day & moved later. Will use shading when we get lots of direct sun on GH.

    O/L  I am going to B & Q on Wednesday , pensioners discount day I'll have a look if they have any and tell you what's called

    just been to the greenhouse it's 81 , without shading I'm sure it would be in the 90+

    having a cup of coffee , what a beautiful sunny day image

  • The green netting I use is bought from the builders merchant by the metre....I think it's intended for use in conjunction with scaffolding.....rather along the lines of safety curtain.....it's a bit heavyweight, so maybe KEF's idea may be better.

    David like your idea when I get my new GH might get some from BM as my new GH is supposed to stand weight of 4 blokes sitting on the top image
