Investing in Lab Analysis

Submitting samples for analysis can often be overlooked with the usual day-to-day demands of a greenhouse operation. However, proactive monitoring of greenhouse resources is a far smaller sacrifice than could be required if plant health declines and diagnostic testing is needed to determine the nutritional imbalance, not to mention the loss of a crop.
