Top-Down Tray drying VS. Hang Drying

The drying process of cannabis is one of the most important processes in the production of cannabis, but it is also the most overlooked process in the cannabis industry. Most facilities still dry their cannabis by hangings stems of the plant upside down in a conditioned room. developed a new drying system where the bucked or wet trimmed flowers of the cannabis are placed in Cannabis Trays ‘Canna-Trays’.
A ventilator sucks the conditioned air ‘Top-down’ through the Canna-Trays.

In a study the results of terpene and THC content of the flowers was compared between the’s system and the hang drying system (stems upside down). Both systems were placed in the same conditioned room, so the temperature and humidity of both drying methods were the same, making the results comparable.
Conclusion: Very few differences in THC and terpene content were found.

Benefits of Top-Down Canna-Tray drying

  • Each part of the cannabis receives the same amount of airflow, resulting in an evenly dried end-product.
  • No wet spots will show on the cannabis, preventing the activation of mold and bacteria.
  • Top-Down Canna-Tray drying is 5-8 times more space-efficient than hang drying.
  •’s systems for Top-Down Canna-Tray drying offer a precise control of temperature, humidity and airflow – allowing the user to perfectionate the drying process.
  •’s ABC-processor allows the user to dry in 3 to 15 days, depending on the chosen settings.
