How come my seedlings are doing fine next to my UV filtering windows? (seeding, plants)

It just occurred to me that, since we replaced our older windows with UV filtering, argon gas windows, that this might not be the greatest for seedlings. They are doing well, but I'm not sure why.

Why wouldn't they. As long as the majority of wave lengths get through the glass that the plants use for photosynthesis they'll be fine. Also heat, moisture and nutrients are more important during seeding anyway.

I was just wondering, since I thought the UV rays that are filtered out to protect furniture, etc., are the ones the plants like.

The vast majority of plants don't need UV light to thrive.

While UVB tends to be harmful to most plants, UVA is generally not particularly helpful nor harmful.
