Hello,
This summer I built a solar greenhouse and it has been working great. About 7 days ago, I found many of the plants have been infested with aphids. Now many of them have leaves that are mottled, curling up and the seedlings are not growing any more.
I also noticed there were lots of whiteflies flying around.
So, I put white fly traps up. Caught most of them. Sprayed an organic "soap" bug-killer on the aphids.
These two treatments seem to have gotten rid of all of the aphids and most of the white flies.
So my question is, What do I do about the plants? Should I tear them all up and start over?
What about the soil? Is it contaminated too?
You can see my greenhouse setup here:

Brian, welcome to gardenbuddies!
Here's a link on white flies in greenhouses, hopefully it helps.
I love your greenhouse! It's something I would love to have. It's interesting that you can keep the greenhouse about 60 degrees and you are down to 27.
Is this your first year with a solar greenhouse? Other than the water, do you use any other heat source?
If you don't get answers here, I think there is a greenhouse forum and a pest and disease forum (or there was, we're doing a bit of consolidating). Otherwise, you can try the advice forum too.
Good luck!

The soil shouldn't be contaminated, sounds like you have got rid of the beasties, but keep an eye on them, they could come back.
As for the plants, take it case by case, you only need to throw out those which are too damaged to survive well.
Unfortunately greenhouses can be a perfect breeding place for pests, as the natural predators aren't around. You found good organic solutions for them though!
