“Plantsauna was the missing link to be sure that I can start with clean plant material. Because I have a Plantsauna at my own nursery location, I am flexible in its use; I don’t need to make appointments with anyone, and, my plant material stays at my nursery for sterilization.”

Product We Used

Two Plantsauna units, powered by a 38-kW oil steam boiler.

Our Solution

Moleda’s Plantsauna is an excellent choice for this sterilization task because of its reliable and stable performance. After the customer heard about our product via the Fresh Forward group, they thoroughly tested the system for two years. After these testing years, they were convinced of the process and purchased two Plantsaunas for their own production of strawberry plants. Our launching customer, Neessen, uses the Plantsauna sterilization method for all their mother plants. During the season, both Plantsaunas run 24/7. We run three treatments per Plantsauna a day, says Johan Neessen, owner of Neessen Aardbei en Aspergeplanten. He treats frigo mother plants and potted plug mother plants in the Plantsauna. The first trials for a mildew treatment with fresh plants and fresh tips also gave good results.

They effectively treat about 2,5 million mother plants per year in the Plantsauna.

Our Results

  • Healthy plants
  • Flexibility in sterilization process, easy at my own location
  • Good root development
