    Hi just wondering what other APers are using to keep the rain out but allowing the sun in. I'm planning on erecting a 6x6m steel shed minus the roofing iron, walls will be shads cloth that can be rolled up. The only material I can find is laserlite roofing sheets, best price seems to be @ the B shop 2 about $42 per sheet:eek:. I estimate I'd need 14-16 sheets 16 x42= $672 :cry:
    Am thinking that a greenhouse plastic film may do the trick, and not drain the bank balance as much:broc1: All feedbank welcome
    Cheers Brian

    I'd go for a mix of plastic and shade cloth. Most of my gb's are under shade cloth through summer and I roll it up for winter to let in more light.

    Gday Brian

    That's exactly what I have done for my setup. I used 30% shadecloth after discussions with my mate (a commercial horticulturist in NQ). His theory is that if you use shadecloth and "block" the sunlight, the resulting plantgrowth will become long and stalky as the plant reaches for the sky.

    All I mainly wanted to do is stop those pesky possums from eating all the new shoots overnight.

    You can see my (gradually growing, excuse the pun) system on BYAP here

    a quick look ....

    Mine has a laserlite roof , but I pull shadecloth over in the summer and open all the louvers and doors, and it becomes a shadehouse.
    I could post some pics of my tomato harvests but you all would hate me Whistling

    I'd love to see your tomato pics and if you've got any tips on how to grow them successfully, that would be appreciated as well!

    Hi Murray,

    Took your advice and here is the clear plastic over the greenhouse, as you can see the shade cloth is still in place so that I can pull it over the top come summer. I decide to use the reinforced (woven) plastic, although twice the price I think will stand up better.

    Only 26deg here today but reached 41 deg inside. Plants were all wilted and was wondering had I done it too early.

    For members info, notice the aluminium tracking with spring clipping to hold plastic/shadecloth in place. Real easy to work with.

    Have had good growth now that the rain has eased and the Dippel able to take effect.

    Very nice crop! Which kind of tomato works best for you in AP?

    Dunno yet Julia. Only had my system running for nearly 5 weeks and its only time for sowing new seeds about now. But I would think they would all do well. Some are more prone to early blight (leaf yellowing), so growing in a humid environment would make this worse.
    That dish of small orange toms in the third pic is one that I wouldnt try in AP as blight attacks it first of all.

    Can you post & some of the greenhouse? Being in Adelaide, im thinking of a mix of laser lite greenhouse and shade cloth. I will attach this to a shed I can use to hold the fish tanks in, therefore controlling the temp better. The shed is and already built with concrete floor and power, its 7 m x 4 m :)

    Sorry Erich, didnt see this post earlier. My greenhouse is an extension of a garden shed that used to be a greyhound kennel.
    It has laserlite roofing and also laserlite around the bottom half of the walls, with louvre windows around the top half
    In the summer I just pull some shadecloth over the roof and secure it down, open up the louvres and greenhouse becomes shadehouse
    This pic shows it a bit. (not a current pic btw :)

    How pricy is this greenhouse plastic material and how long does it last? :)

    Hi Erich
    just saw your post, I made my greenhouse a few months back and got
    all materials at Monbulk Rural in Victoria (purchase date 11/06/2010)

    Solarweave 2.7m wide $7.70/Lmt

    greenhouse plastic 7.5m wide $13.55/Lmt

    shadecloth horticultural premium 50% 3.66m wide $10.30/Lmt

    vinipet aluminium channel $3.85/mt

    greenhouse plastic is used for the roof as it lets through the most light
    solarweave has threads in it to stop rips but lets through less light
    hence used for the walls (but can also use for roof)

    They told me it should last 5-7 years
    ( hence assume 3-5 years, call me cynical)

    Can also use polyflute (twin skin polycarbonate sandwich)
    lenghts available 1.83 to 7.135 m 1.22m wide priced $8.80 sqm

    hope this helps

    Lou
