Help! I just put up my first greenhouse - using solexx panels. Last night there was a power failure sometime in the night - I didn't wake up and the greenhouse temp dropped to 35 degrees fah. I don't know how long it was at that temperature. I didn't wake up until 7am - immediately noticed my remote temperature (next to my bed) and FLEW outside... and reset the heaters (they apparently TURN off in case of a power failure)

I have mostly Cats but a few other species, including phals, paphs, dendrobians and half a dozen more...

My question is - are they all toast? Will they slowly die over the next few days? Or might they survive. There's about 250 plants in there.

Its the Holiday season and I'm swampted at my business (no day off for last 49 days)... so I did TWO electric heaters (plugged into different circuit breakers) as a stop-gap before investing in a gas heater. Until less than 3 weeks ago I've been an under-lights or windowsill grower. This is my first greenhouse...and this is what I feared (and to think I was panicking a week ago when it dropped to 58degress... eeek!

I've immediately brought the temperature up... but don't know if there is anything else I can do... besides invest in a gas heater...

THANKS for anyone who has experience here...
