Light , PPFD / DLI  Testing 

Indoor agriculture is, more than ever, “farming by the numbers”, and data-analytics is crucial to measure important lighting and water level conditions to help you assess, analyze and evaluate to improve production and conserve resources.
Getting instruments to measure these data is expensive already plus you'll have to do intensive study afterwards to be able to analyze the data you get. With John's experience and expertise throughout the years, you'll be sure to get the right recipe for your beloved plants.


Water Activity Testing

What does water activity mean in cannabis?
Harvested cannabis (marijuana and hemp) must be sufficiently dry to allow for storage and transport.  

Water activity (aw) is a measure of the energy status of water in a product.
Water activity determines if molds, yeasts, or bacteria will be able to grow on biomass during storage. Dried biomass will typically have a water activity in the 0.60 to 0.70 aw range.
 It is Key to know and have the acrute amount of water in your product to ensure quality and freshness 

How to Measure Light Intensity

Measure the quantity and quality of light for a new generation of indoor farmers who use artificial lighting as a substitute or complement to sunlight.

Light is formless and hard to measure. And yet, as an indoor farmer, it’s a crucial to get your lighting right; quantity, intensity, color and duration (diurnal and seasonal rhythms). These are the data components of sunlight that are the challenges of artificial lighting to emulate.

A PAR meter can provide you reliable measurement with comprehensive data tools to help you collect, analyze, and evaluate light data to help you understand your light-to-plant relationship and assist you in making better decisions for your business.

Water Activity

Water activity is widely recognized for the safety it provides to food because of its control of microbial growth and it is considered a critical control point for preventing microbial contamination. Water activity provides this same determination of safety in cannabis and consequently is already a part of cannabis regulations in Canada and many parts of the world. 

However, at this point, it remains primarily associated with edibles, linking it back to food safety. While water activity is important for the safety of cannabis edibles, it is also  very important for storage stability of harvested buds / flowers. If cannabis buds/ flowers are not dried to water activity levels below 0.65 aw, they can support mold growth during storage and transport, leading to the subsequent potential for inhalation of mold spores or mycotoxins. In addition, water activity controls the rate of decarboxylation that can lead to the breakdown of tetrahydrocannabinol (THC). 

Finally, water activity is correlated to additional critical product quality attributes that are associated with shelf life. In fact, it is possible to predict shelf life based on water activity and to establish an ideal water activity specification for any cannabis or hemp-based products.
