A microscope is an excellent tool in assessing the quality of your compost or compost tea. The microscopes we have below are comparable to or better than the Leica CME in image resolution, at a fraction of the cost. Our goal is to provide a functional yet inexpensive quality microscope to support microbial based horticulture which we believe is of great benefit to the farmer, landscaper and home gardener. We maintain it to be just as much a tool as a shovel, hoe or lawn mower. Each microscope will also come with a DVD produced by Tim Wilson teaching the use of the microscope, general microscopy and some compost and compost tea observational techniques. You may wish to consider adding the Microscope Identification DVD to your order for additional videos and identification skills.
