My freshly built cool growing greenhouse

    <= Evaporative cooler will be installed on this side of the greenhouse.

    This has been a long wait to make it happen, because my husband had a strong resistance to be taken over inside and outside of house by orchids, and we hardly have much of land space (as you can see the challenge of maximizing the size of the greenhouse; 6X8 floor space but lost one corner, the peak of the ceiling is 10.5 feet).
    But, finally he built it. I have not moved in all of cool growing orchids yet.
    We still have some stuff to think about completing it.
    1. Need to choose a evaporative cooler (size approx. 340cf ) that has a hose connection, not too big and size of the vent has to be smaller than 13inches (because of the size of the panel).
    Does anyone know a swamp cooler it comes with a duct system (I can install from under the floor)?

    2. We haven't decided about the gap between greenhouse floor and the ground; it's good ventilation for summer, but too drafty in winter.

    3. It is very bright and sunny in the morning so, I am worry about summer time heat. It needs shade cloth ASAP; cover the angled (left side)long roof and it might need shade cloth along the weird angle wall as well.

    4. Separate watering system has to be installed for mounted plants especially Lepanthes. Irrigation water supply is pumped up from a rain barrow therefore it's not easy to have two separate timer.

    Misting system for irrigation is installed, and the water supply is from a rain barrow. It still needs to update for built in fertilizer supply from a bucket (it calls siphon mixer from Hozon and it might be interesting to try this product, the site is here http://hozon.com/). But, it might promote algae growth by spraying fertilizer everywhere.

    The entire roof peak opens when the greenhouse gets warm.

    The distribution fan disturbs the warm air pocket to distribute the temperature evenly from near the floor to the ceiling.

    I am very excited!
    If anyone gives me suggestions, I will appreciate it.

    That is beautiful. Congratulations. Looks like your husband is a very good carpenter. Are the benches custom made, too?

    As for suggestions ... you will definitely want to seal off the space between the ground and the walls. At a minimum use some hardware cloth. It would quickly become a haven for mice, rats, possums, etc. At least in my environment it would.

    Also, I have tried the Hozon siphon. In my situation I wasn't running enough volume through the hose to make it work properly. For it to work properly the water flow would blast the plants.

    Have fun. It looks wonderful.

    Thank you Kelly.

    Yes, the benches are also custom made.
    Their legs are attached to the base of the greenhouse walls to maximize the foot space. He used thin stripe of cedar wood and glued together to make the benches.
    It is very convenient that his hobby is woodworking.

    As for Hozon siphon, I have been given and I do need to try to see how it works. If it needs good water pressure, I might need to use it for my warm growing atrium that I am using tap water. But, it might clog the high pressure misting system.

    I have never thought about rats coming into the greenhouse feasting orchids.
    It might need at least mesh to block them out then.

    For misting system for mounted plants, you could use a system used for vivariums, where you have a submersible pump in your rain barrel, and a separate small electric timer for that. Ones with 1/2 hour on/off intervals are pretty cheap (i.e. disposable).

    Hum.

    Thank you Carl.

    The irrigation already uses a submerged pump but, it is true that I can use vivarium stuff and having a smaller rain barrow inside of the greenhouse for it.
    What exact timer do you suggest? I do know some small timers do not handle high wattage pumps.

    I just use any timer made with ground outlets... They're usually about $10 or so at the big-box stores. Brand varies, but probably all of them come out of the same factory in Shenzhen...

    I see.
    That's why it is disposable then.
