How to Manage Water Load in Your Hanging Flower Baskets

Oasis watering system from ControlDekk

The Oasis uses an electro-mechanical module in which the user sets a pre-determined weight desired for correct plant watering.

The process of knowing whether you are giving your hanging baskets the right amount of water can sometimes take a bit of guesswork. It was this dilemma that inspired Michigan growers Jared and Jordan Dekker of Dekker Brothers Greenhouse in Hudsonville, MI, (as well as Len Logsdon, a Controls Engineer and a Master Electrician with more than 30 years’ experience in the greenhouse automation industry) to design a watering solution for hanging baskets that uses the weight of the basket as a starting point.

The system, called the Oasis, can be installed on new or existing greenhouse cable conveyors. It uses an electro-mechanical module in which the user sets a pre-determined weight desired for correct plant watering via a local controller, an office PC, or a mobile device. As each basket passes through the Oasis module, its weight is determined. The smart controller opens the proper water valve for only the time necessary to achieve the grower’s target basket weight.

The Oasis module is equipped with a Smart Optics sensor that determines if there is a basket present on the hook and whether it is an upper or lower basket. The Oasis system design eliminates the need for tabs on basket hooks and mechanical switches.

One benefit of using the Oasis system at Countryside Greenhouse has been less water runoff from hanging baskets onto the plants below them.

Real-World Trials Show Other Benefits

Early trials of the Oasis proved successful at Dekker Brothers; however, the team at Control Dekk (the name given to the new company supplying the Oasis) knew it was important to get similar results in other operations. Fortunately, they soon began working with nearby Countryside Greenhouse in Allendale, MI, which produces more than 200,000 hanging baskets annually and was looking to upgrade some of its irrigation components.

In 2016, Countryside installed the Oasis system on 12 new basket lines in its retail area. The following year, it added 18 more to the basket lines in its production facilities.

“The Oasis has fewer parts to worry about, so it’s been easy to work with,” says Matt Vissers, Head Grower at Countryside Greenhouse. “It has a touchscreen display that is easy to read and quickly tracks the amount of water in your baskets, so you know what got watered and what didn’t. From a growing standpoint, it’s been very consistent.”

Jesse Vanderschuur, Countryside’s Production Grower, says there’s been another benefit: less runoff from water in hanging baskets onto pots below them.

“We had some die-offs in our first three bays with a previous watering system because the plants below were constantly getting the drip from overwatering baskets that may be half dry and half wet,” Vanderschuur says. “This new process helps us water our baskets more evenly.”

Bill Kennedy, another Production Grower at Countryside, says it’s been easier to decide when to water knowing that you wouldn’t drown the baskets that were already wet.

“The crop in the baskets was equal in weight through the whole system,” Kennedy says.
