Week 3 sucked, there wasn't too much progress to see and the gnats became pretty annoying. The Heat mat was able to increase the temperature but I wasn't quite satisfied with the fixture. This way the humidity accumulated below the mat and the gnat really enjoyed the pillow. I killed every day at least 15 gnats or so, the yellow boards did help a bit even tho they are only meant to monetize the problem instead of fixing it. I already ordered nematodes but they took quite a while to get sent to me.
