Greetings Again All,
I'm afraid that the fluctuation in temperature in my small green house may have doomed my seed starting effort.
One day early in the a.m. the temp was 80 degrees in there. I just checked and the inside temps are now hovering at around 50 degrees.
Can these seeds (no germination yet) withstand these high fluctuations and still remain viable?
Thanks in Advance!

I'm not an expert, but I don't think the 80 is a problem. I'd be more concerned about temps dropping below 50. My little GH frequently gets over 80 during the day. Watch the water needs, check it every day.

Thanks Cathy,
The original idea of the miniature greenhouse was to winter sow:) I thought that perennials such as shasta daisy needed cold weather to produce well.

Marlene, that does make a difference, if you aren't doing tender annuals, your low temps aren't a problem. I would try to vent your greenhouse so the temps don't go any higher.

the greenhouse does have a venting mechanism. (I open the zippers:) However, several times now, I have failed to get to the zippers on time. A couple of times in the morning and a couple of times when I zipped up for rain etc., ran some errands and when I got back to the house, voila, steam bath.
I wonder if there is a way to save these guys?

Since your intention is wintersowing, I would just leave the vents open. The cold is okay.

80 degrees won't hurt them... around 90-95 starts getting dicey, but remember even if the temp inside yoru mini greenhouse shoots up to 100 degrees, it will take a while for the soil temp in your containers (the actual temp around your seeds) to go that high.

Thanks Cathy and Jill for your feedback. I was starting to think that I should dump and start all over again.
What do you think about the coneflower, shasta and yarrow and sweet peas? Have they survived the heatwave?
Cheers!

I'm betting you are going to be just fine, but Jill knows the most about everything.

All I know is that I've read that most seeds are fine unless they get to a 90-plus temperature (some sources say 92, others say 96)

Sweet peas can just go in the ground now, I would think.

Yes I know:) Sweet peas should go in the ground. The only problem is that I haven't been able to get out to my rented garden plot to till etc., So I thought I'd get an early start on the sweet peas.

You could probably start your sweet peas in their pots outside of the mini green house...

i started peas in paper towl tubes so they could be transplanted with minimal disruption. they were in good shape until the voles ate all the shoots.

We received a couple inches of "snow flurries" this morning, my jugs are all covered. It should be interesting to see how my hardy annuals do.
