Medical Cannabis

GMP-compliant air-conditioning technology for Cannabis cultivation
Complete. Efficient. Certified.

In order to profitably cultivate cannabis in compliance with GMP, you need an air-conditioning system that ensures consistent growth conditions and the highest level productivity.

As one of the leading global partners for air-conditioning and environment simulation technology, weisstechnik® benefits from the necessary expertise in plant breeding and in the pharmaceutical industry and currently has the biggest portfolio on the market.

Strict regulations for consistent quality

Medical cannabis must be cultivated in closed rooms and the active ingredient content may only slightly fluctuate.

The following regulations regarding quality, production rooms, hygiene, equipment, tests and documentation are to be observed during cultivation:

  • GMP (Good Manufacturing Practice)
  • GACP (Good Agricultural and Collection Practice)
  • Cannabis flowers monograph from the DAB (Deutsches Arzneibuch - German Pharmacopoeia)

Demanding requirements for air-conditioning technology

In order to ensure consistent growth conditions when outside conditions fluctuate, an intelligent air-conditioning system is needed.

Temperature, humidity, light, supply of fresh air and air flow must be precisely controlled in order to guarantee a consistent quality of cannabis.

Experienced partner in the pharmaceutical industry

We are an experienced partner for large air-conditioning projects and have excellent references.

Our many years of experience with the complex requirements of the pharmaceutical industry and our cooperation with renowned research institutes gives you an important advantage over your competitors.

Efficient plant growth rooms

Fitotron® climate test chambers and rooms for plants ensure stable and reproducible climate conditions and are the centre piece of a cannabis cultivation system.

They allow the precise control of climate and light, and meet the most demanding precision and uniformity requirements. We develop tailor-made climate room solutions in a range of sizes, which are optimally adapted to your cultivation requirements.

Intelligent ventilation design

The Smart Air Flow ventilation design developed in accordance with scientific findings optimally supplies plants with conditioned air.

As a result, they absorb more nutrients. It encourages growth and ensures you a significant additional yield.

The A to Z of production reliability

The high quality requirements which we demand of our air-conditioning solutions are also the benchmark for our quality of service.

Our service includes specialist consultation as well as a Germany-wide and international service network. This network allows fast reaction times in the event of faults and provides the highest level of production reliability.
