It's hot in Phoenix

[rbarata]

I decided to do what I didn't want to...to turn on the AC all night in one of my growing rooms.
Temps are now consistently over 36ºC (97 F) and frequently 40ºC (104 F) and humidity around, or lower, 20%.
Usually what saves the situation are night temps almost always between 16 and 19ºC (61 to 66 F) and HR near 80% but in the last days and the next we have 22ºC (72 F) at night with HR around 60%.

I have been watering twice a day some of my plants (Laelia anceps, for ex) that are under full sun most of the day and inside almost all of them as the humidity is too low.
A lot of work, as you can see.

P.S. - I'm really tempted to use SI units when mentioning temperatures. It's annoying to have to convert it everytime.

No problem here! By this time, people in the US (at least orchid people) should be pretty comfortable with SI units... this being the only part of of the planet where they aren't standard. <sigh> If anybody in the US wants to convert units, google the various converters or haul out the calculator... I'd be happy to supply formulas to anybody who wants them.
