Cannabis in Vertical Farms

Raise the Bar

Tailored lighting solutions, delivering unrivalled performance for your cannabis plants.

What is it?

A customisable lighting platform adaptable in length, spectra, and performance to the unique requirements of your indoor farm.

How does it work?

Engineered with collaborative customisation at its core, the Align Platform offers unrivalled performance by enabling growers to tailor every aspect of their lighting solution.

What does this mean for my cannabis plants?

A significant PPFD, intensity and spectral uniformity improvement, accelerating plant growth whilst increasing bud density, dry mass, CBD or THC concentrations.

Uniformity Leadership

The Align Platform utilises custom extrusion manufacturing techniques, advanced LED, and optical technologies to ensure optimal photosynthetically active radiation (PAR) light-use efficiency and unmatched intensity uniformity, whilst requiring fewer light-bars vs the competition.

Industry Standard 1200mm LED Light-Bars

29% of Grow Area is +/- 10% of the 1000µmol/m2/s PPFD Setpoint

Bloem Align Light-Bar Platform

100% of Grow Area is +/- 10% of the 1000µmol/m2/s PPFD Setpoint

“Intensity uniformity is the consistency of total PAR light distributed over the growing area. This is typically measured at the crop canopy by the volume (%) of the grow area that falls within the specified tolerance of the PPFD setpoint.”

Spectrum Consistency

The Align Platform is engineered to be spectrally uniform and excel within low headspace (150mm), multi-layer environments. The PCB, LED & optical design ensures consistent distribution of the desired light recipe at the plant canopy with minimal deviation of the recipe’s wavelengths.

400-500 nm (Blue) Spectral Uniformity

500-600 nm (Green) Spectral Uniformity

600-700 nm (Red) Spectral Uniformity

“Spectral uniformity is the deviation in PAR wavelength bands over the growing area, measured at the crop canopy, compared to the light-recipe emitted from the fixture and the spectrum setpoints.”

Using Bloem’s Wand Platform

The Bloemteknik Wireless Adaptive Network Delivery (Wand) platform provides advanced dynamic control for single and multi-channel grow lights.

Blue Light
400 - 500 nm

Enhances compact, bushier growth that can’t support bud formations

Essential in seedlings for promoting rooting and strong stem formation

Prevents against pale/yellow and weak/floppy plant characteristics

Green Light
500 - 600 nm

Penetrates deeper below the primary leaf layers producing yields below the upper canopy

Easier to detect pests, pathogens, and nutrient deficiencies

Improved human visual quality for a practical working environment

Red Light
600 - 700 nm

Flowering under red wavelengths can result in larger, fuller plants with increased cannabinoid content

Encourages flowering and budding, vital for germination and flowering stages

Increased biomass, leaf area, length and height and production of flowers for larger yields

Far Red Light
700 - 800 nm

FR photons travel through the canopy efficiently

Elicits shade avoidance response, promoting stem elongation

End of day FR treatment can be used to artificially extend night cycles

The quantity of photosynthetic active radiation (400-700nm) required is defined by the Daily Light Integral (DLI). DLI refers to the quantity of PAR the plant is exposed to within a single day (24-hour period). Each plant, including cannabis plants, have a minimum and maximum DLI to facilitate growth and this varies by strain, development phase, CO² supplementation and other environmental parameters inside the CEA facility. The desired photosynthetic active radiation density (PPFD) can be calculated from the typical DLI target and exposure duration (photoperiod) shown below.

Examples of cannabis DLI & PPFD targets without CO2 supplementation
(400-800 ppm CO²):
Propagation phase recommended DLI of 10-20 mol/m²/day and 18-hour photoperiod.
10 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 154 µmol/m²/s minimum PPFD
20 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 308 µmol/m²/s maximum PPFD

Vegetative phase recommended DLI of 25-40 mol/m²/day and 18-hour photoperiod.
25 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 385 µmol/m²/s minimum PPFD
40 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 617 µmol/m²/s maximum PPFD

Flowering phase recommended DLI of 35-45 mol/m²/day and a 12-hour photoperiod.
35 mol/m²/day / 12 hours / 60 minutes / 60 seconds = 810 µmol/m²/s minimum PPFD
45 mol/m²/day / 12 hours / 60 minutes / 60 seconds = 1042 µmol/m²/s maximum PPFD

Examples of cannabis DLI & PPFD targets with CO² supplementation
(800-1400 ppm CO²):
Propagation phase recommended DLI of 10-20 mol/m²/day and 18-hour photoperiod.
10 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 154 µmol/m²/s minimum PPFD
20 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 308 µmol/m²/s maximum PPFD

Vegetative phase recommended DLI of 40-60 mol/m²/day and 18-hour photoperiod.
40 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 617 µmol/m²/s minimum PPFD
60 mol/m²/day / 18 hours / 60 minutes / 60 seconds = 925 µmol/m²/s maximum PPFD

Flowering phase recommended DLI of 45-65 mol/m²/day and 12-hour photoperiod.
45 mol/m²/day / 12 hours / 60 minutes / 60 seconds = 1042 µmol/m²/s minimum PPFD
65 mol/m²/day / 12 hours / 60 minutes / 60 seconds = 1504 µmol/m²/s maximum PPFD
