Definition - What does Sprench Method mean?
“Sprench” is a combination of the words spray and drench. It’s used to describe the application of growth regulators to plants in a manner that is not quite spraying, yet not quite drenching, and is most often used by commercial growers.
In spray applications, the growth regulator is primarily applied to the leaves of the plants in question as a spray or light mist. It generally does not contact the growth medium. In a drench application, the regulator is applied to the growing substrate and little or no contact is made with the leaves. With the sprench method, the growth regulator is applied to both the leaves and the substrate.
MaximumYield explains Sprench Method
Growth regulators are used to achieve specific stem heights in plants grown in commercial operations. Depending on the needs of the grower, regulators can encourage rapid growth, encourage brief growth, or even discourage growth. There are several ways that growth regulators can be applied to plants in a commercial growing operation, but one of the most popular is the sprench method.
Perhaps the best way to think about a sprench is as a drench that’s performed using spray equipment. Basically, this would involve spraying plants much more heavily than with an actual spray application. This causes the growth regulator to contact the leaves, but also to soak into the growth medium in which the plants are rooted. Generally, a boom mister or sprayer applies three or four times the volume of growth regulator to the plants than would be necessary with a spray application alone.
A sprench containing growth regulators may be the right choice if a grower wants to slow down growth as plants near maturity, or during the propagation phase of crops that grow very quickly. It can also be done with garden plants up to the point that budding begins.
The sprench method can also apply to the applications of some pesticides and fertilizers; however, the majority of these substances are either applied to roots OR leaves, rather than both areas.
