    Hi All

    Our place the Temp ranges from 45' cel. in summer to 23' cel. in winter, RH around 60 to 65% average, We have planned for natural ventilating green house , is it recommend to cool the green house with cooling pads and fan in summer for growing leafy Greens, or is it enough to maintain water root temperature, need advise on this

    Thanks

    Hi and welcome to the forum.

    I'm assuming when you say "cooling pads", you are referring to evaporative cooling pads mounted where the fresh air is drawn into the shadehouse. This can work well if set-up correctly and the atmospheric humidity level isn't already too high. I have a seen a few examples where it has been applied. From memory I think one of the large commercial installations that Murray has visited utilises them.

    Most plants are fairly resilient to high air temps as long as the root zone doesn't get too warm, so keeping the water temp, and therefore the root zone temp, down, is a good idea. It would need to be kept cool for the fish anyway.

    I would just ensure you are growing plant types/varieties that can handle the warm weather. Also, in hot weather ensure you harvest very early in the morning before it gets too warm, this will increase the shelf life of any produce.

    Cheers!

    Hayden.

    Hi

    Thanks for the reply, as i told before the temp ranges from (45'C max to 25'C min) in summer and winter, So do you think leafy vegetables can grow well in summer if i maintain root zone temperature. if so i can install a natural ventilating greenhouse and put fans for air circulation. which will be more commercially viable than cooling pads setup

    Yes the cooling pads is evaporative type pads,
