This was our fifth sample we looked at. The light came on nice and quickly, a low bright green. This indicated that the soil had good EC and plenty of microbial activity and was a good soil for us to use for our plants. We noticed that the soil by the rotting tree had the brightest green rating, however this area had the second best soil sample out of all our samples that we looked at.

This was our fourth sample we looked at. The light came on to a high dim but was not bright green. Even though is was sandier that the other samples it still had microbial activity and extra minerals and pretty good EC. Wasn't ideal for our plants.
