Grodan supports quality, yield and scalability for Grow Motion

Swiss medicinal crops producer Grow Motion has been operational for less than a year, but already has ambitious plans for future expansion. Grow Motion is currently growing CBD (low THC content). Therefore it is not necessary to obtain an official licence in Switzerland. “Grodan’s solutions play a part in giving us a bigger and faster yield of high-quality flowers than we could achieve with soil,” says Benjamin Gutsch, who oversees the production facility. “And when we decide to scale up, we know that Grodan’s uniform growing media will give us perfect results every time.”

After three years of planning, construction and arranging licences, medicinal crops producer Grow Motion – based in Solothurn, Switzerland – recently became operational. “We are now seven months into production, and we’re happy to already be cultivating 6,400 plants,” says Benjamin Gutsch, head grower at Grow Motion.

Having previously worked with medicinal crops in Spain and Germany, Gutsch moved to Switzerland in August 2022 to put his experience to good use at Grow Motion’s new facility. He was personally involved in the final preparations, and today he and his team of six people take care of the day-to-day operations at the facility. That currently comprises a mother room and a growing room, each measuring 145m². “Quality is very important to us, especially because we are selling to the pharmaceutical industry. And Switzerland is a good country in which to make good quality,” he comments.

Tailored approach to irrigation

Grow Motion sources all its growing media from Grodan, specifically two different sizes of plugs and one size of blocks. “We use the bigger plugs for our mother plants and the smaller plugs for the clones, which we subsequently place directly on top of the blocks,” says Gutsch. “We were keen to use blocks rather than slabs, partly because blocks are more visually appealing when visitors come and look inside our facility through our showroom window,” he explains. “But blocks make it harder to get a uniform water content when using a dripper, like we do. So the Grodan experts helped us to set up the irrigation cycles at the beginning and developed an adapted plan for us.”

Overcoming challenges

To maximize the production surface, Grow Motion has a three-layer setup in the growing room. “However, this presents its own challenges. For example, the microclimate this creates inside the room can be pretty difficult to manage, posing a greater risk of fungus. The Grodan blocks help us to minimize that risk,” he comments.

“Additionally, to ensure the plants don’t grow too close to the lamps and block the radiation, we need them to stay wide and bushy rather than tall. To achieve this, we work with a very short vegetative phase followed by 60 days of flowering in the cultivation phase,” says the head grower. “Based on Grodan’s advice, we soak the blocks completely based on weight and then let them dry back for 8 to 10 days. This approach is working really well for us now, and even allows us to use a slightly higher EC.”

Steering the crop with more precision

Gutsch monitors the crop closely using Grodan’s sensors and the GroSens interface, and he is clearly a big fan. “The sensors are amazing and I would advise everyone to use them if they’re working with blocks because it makes a grower’s life so much easier. And the system connects easily to our Priva computer, so all the information from both the climate computer and the sensors is at our fingertips in GroSens for analysis,” he comments.
