    I'm interested to see what others think about temperature ranges. The "Max" temperatures are your summer highs, and the "Min" temperatures are your winter lows. Please only vote for 1 max and 1 min. Thanks.

    Jon, have you considered adding "upper 70's" and "80°F max"?

    No. Plants that grow in that range would not be considered "cool growing".

    What determines "cool" for you?

    For me it is the minimum night temperature. My Masdevallia coccineas are generally considered cool growing, but they experience 85 F days frequently in the summer and occassionally 95+ with no problem in one of the greenhouses.

    Do you have a GH you consider a "cool greenhouse"? If so, what are the temps in there?

    Yes, my "cool" greenhouse is 50 minimum and 80 maximum (except on really hot days when it is higher). The swamp cooler is set to come on at 80F. I don't grow my coccineas there.

    How about this as an option, "I don't grow cool orchids, because I live on the Sun." That's the one I'd pick.

    The Fonz would not participate in your poll and he was cool.

    I was born that way, can't help it. Some call it difficult, some call it honest.

    I think this site needs an "I Like" button, like on Facebook, for some of these comments. You guys crack me up.

    How about a poll for min/max temps for WARM growers?

    Thanks to Mother Nature (bitch) I'd have to say 38°F* min to 99° max.

    The min reading referenced above was achieved 2 nights ago when I was out of town and my (heating) water pump smoked. We'll see if I have black orchids in 2 days.

    *I don't recommend this as a minimum temp for warm-growing orchids. No sir'ee...

    I don't grow orchids that require cool temperatures. But I'll do the polling thing anyway coz I'm a team player. There will be lots of guessing going on but I'm a good guesser.

    Jon, I would be happy to put in my vote. You asked what "others" thought of the range, but you aren't really giving us the chance to answer truthfully by limiting it to what you think is appropriate. Kind of a self-fulfilling poll. Can't you extend the range so you get a complete picture?

    You may just hate those of us who are difficult, but this is an important question.
