Max temp and growing conditions

[lauraeli]

Is it possible to grow phals on top of the air conditioning unit? Outside, i mean. Or would I have to move them while it was running?

I had nasturtium growing on the rail out there, where the hot air blew directly on them. They dried out quick but, as long as they got enough water, the only thing they complained about was the lack of light. Not sure if nasturtium are considered heat-tolerant, but they did okay.

Probably not going to grow anything in that spot this year...except maybe my rosemary since it is already there. But i was considering setting my phals on top of the unit (the hot air would not be blowing directly on them there). Not sure how they would take the higher temperature. But of course I could move them inside on the really hot days.
