    Default Here's my set-up for 2000 orchids in UK...

    The greenhouse is 35 feet long , and inches under 15 feet wide. The floor 30 inches below ground - the steps down form my potting bench - hence the bins ( compost etc ) around the entrance. Bubble-insulation on the outside, also shade cloth ; last layer is there in the pic, waiting to be taken off. 3 layers used in midsummer. Floor is gravel for drainage. Dropped floor system is good for heat conservation and natural humidity.
    Heating by gas boiler , hot water radiators ; central heating timer gives me different day and night temperatures.
    Two 5 foot dia sweep fans in the top - not easily seen in pics because of the fan movement.
    Supplementary lighting - 4 x 400 watt lamps moving on a track below the fans, switched via photo-cells .to give a minimum of 10 hours light at 12000Lux ( just over 1000 foot candles if you are not metric) each day. This is the latest development in a (so-far) 2 year development programme for lighting and I haven't got the right photo-cells yet - at present the lights come on only if bench level light is below 4000 Lux - but new cells are on their way to me. Today - southern England, mid-October, sunny, natural light is giving me 15000 lux anyway , but maybe not for quite as many hours as I want per day.
    A lot of plants hanging up for best natural light, some on long hangers to be in the supplementary lighting zone. Catts and oncids below the lights, paphs outside it. Oncid bench has all plants in hydroculture -the blue trays - presently 18 of them, but up to 25 at times -are 25 inch x 18 inch typically holding 20 plants - depending on pot size, and 1 gallon of nutrient mix ( about 1 inch deep). Currently a hundred or so soft cane dendrobes and other things are out of the greenhouse , in a cold frame to get their cold rest and encourage flowering.
    Swamp coolers to keep temperatures down in the summer,and thermo-strut ventilators which are disconnected now until the spring.
    Any questions ?

    In case the two "missing" panes of glass at the door end puzzle you , they are actually replacements, not yet given the shade-whitening treatment. This house is glazed in toughened glass, which sometimes turns to a sheet of crystals for reasons best known to itself ( glass is a peculiar material but I won't go into that) I have had 3 panes go like this out of the 50 or so used, in 14 years - this greenhouse was originally built at a former house, and taken down and moved here 6 years ago when I came here.

    Great setup! Beautiful plants! When I read your introduction, to the forums, I was hoping to catch a glimpse of your collection! Thanks for the cool pictures!

    What a great idea to us a cold frame, to give the orchids, the winter chill they need! I have been wanting to get a cold frame for many reasons. And I think you just sealed the deal...maybe I can convince my husband to build one!

    I have been wanting to get a swamp cooler for my greenhouse. I wonder if it would work good in my humid Midwest summers?

    Swamp coolers work to cool the air by evaporating water ( and increase humidity) - and generally speaking high humidity is no problem with orchids - on the contrary . There is just one exception - when it gets too humid white flowers spot quite quickly - so if you go in for white phallies you would have to take them somewhere else - maybe you have an air-conditioned room somewhere , with low humidity ? But otherwise I imagine one would work well for you. My problem in UK is even getting one ! We don't often have a summer where any kind of cooler is wanted, but maybe things will change if global warming is real.

    Nice setup. I am impressed by the size of your greenhouse, by Philippine standards that could be big enough to be a bedroom! From the photo, I even think your greenhouse space is even bigger than my bedroom. LOL!

    The plastic tubs filled with water with the orchid pots sitting in it gave me a great idea to collectively grow the plants in S/H and raise the humidity all at once.

    Though here in the Philippines, we have to be careful and vigilant specially with mosquito larvae that might develop for risk of dengue. Altho adding some Physan into the water can acts as a deterrent against the larvae developing into winged adults.
