One way growers can improve efficiency and manage costs in the greenhouse is by ensuring proper hydration of compressed growing media. When a substrate is hydrated correctly before use, growers can maximize volume, reduce waste, and create a more consistent growing environment. This not only helps optimize input costs but also prevents cultural challenges that can lead to increased labor and resource use down the line.<\/p>\n
As mentioned, the initial hydration of compressed substrates is key to maximizing the investment of this crucial input. Proper hydration will add several additional cubic feet per pallet of substrate, and with good potting practices, fewer cultural issues down the line. Some common challenges encountered when filling containers dry include difficulty keeping newly transplanted plugs moist as they root out or collapsing the mix by overcompensating with heavy watering-in of new transplants. Both extremes can cause various headaches and cultural issues throughout the life of the crop.<\/p>\n
Steps for Success:<\/h4>\n
To avoid these problems and realize the maximum yield from compressed peat-based growing media, the following steps must be taken consistently on the potting line:<\/strong><\/p>\n To determine if the mix is at the right moisture level prior to container filling, use the squeeze test pictured here. Educate potting line staff on this procedure as they are the best ones to notice a problem and help handle it quickly.<\/p>\n Too dry<\/strong> Optimum<\/strong> Too wet<\/strong> Compressing peat-based substrates is an important cost savings format as shipping heavy water long distances is expensive. However, adding water on site to hydrate and re-expand peat mixes is more sustainable and less expensive. At Berger, our goal is to deliver as much volume as possible, which is why we set standards for low water content in our products. Adding approximately \u00bd gallon of water per cubic foot of Berger media enables maximum product yield.<\/p>\n\n
