That is a 12 inch dish, they are very very tiny half or less than the width of a cardboard match...that's the best i could get with the microscope/iphone combo:-D
not sure why they won't zoom, It works for me. I would say they might be a bout 1mm long...they look like pics on the internet of springtail larvae..now it looks like there are thousands in the dirt, but they like to make a small appearance in the dish under the pots....going to try some...
Are Springtails good or bad? is there a good amount or is it when there is an way too many that it gets bad? Is there any way to kill them? Do you think they are coming into the grow area from bagged soil or coco?
