Throughout Percival Scientific’s 125-year history, our ability to meet unique research requirements and to control multiple critical testing variables has made us an industry leader.

Because we understand the five stages of delivering a successful cannabis harvest, we know how to engineer controlled environment chambers to ensure consistently precise conditions at each stage of cannabis production.

We also give you flexible design options so you can choose the right products for your space and research needs, from reach-in chambers to walk-in rooms to grow houses.

STAGE 1: Tissue Culture

  • Sterile conditions guarantee each batch of plants is pathogen-free
  • Genetic integrity of the strain is 100% retained
  • Cryogenic storage of mother plant tissues enables reuse

STAGE 4: Blooming

  • High-intensity light and longer daylight cycles to build plant mass and root structure during final vegetative growth stage before blooming begins
  • Shorter life cycle and reduced temperature to trigger blooming and develop THC and CBD resins
  • Low humidity to prevent mold growth on buds
