A grower’s financial performance is a function of crop yield and potency.
Following strain selection, the grower’s financial success becomes a function of managing/optimising each of the following parameters:
- Lighting – Supplemental lighting will increase number of harvests as well as yield and potency of crop.
- Nutrition – Appropriate nutritional and the availability for uptake has a fundamental impact on crop performance.
- Humidity – Reduce humidity to reduce risk of fungal growth within the greenhouse.
- CO2 – Increase CO2 levels to accelerate photosynthesis activity for improved root development and plant growth.
- Temperature – Optimal temperature for the plant is impacted by heat generated by traditional lighting technologies which requires increased distance from the canopy and increased load on cooling equipment
Plant light requirements:
- Daily Light Integral – total amount of photosynthetic light (380nm-740nm) delivered to plants each day
- DLI is measured in moles of light per day i.e., Photosynthetic Photon Flux Density (PPFD)
DLI impacts both:
- Yield per plant; and
- Potency of the yield.
Cannabis light requirements:
- Veg phase : 25-45 (delivered over 18 hours)
- Flower phase : 30-40 (delivered over 12 hours)
