Well its been a few days since Ive been using a small 4" fan and I've noticed that the coco coir seed starter mix was very dry after getting a good drink Sunday was very dry. So early this morn I watered all cups I knew the fan would make them dry out faster, it usually takes 6 or 7 days now in 3 days they needed water I'm sure the fan had a lot to do with it. But that coco coir has to be the quickest drying mix ever!! Anyone else here notice this too?
