Why Fragmented Control Systems Fail at Scale
Managing a single grow room with one light controller is straightforward. Managing 10 zones, multiple crop types, and different growth stages under separate systems is not
DLI - How Much Light Does My Plant need?
DLI stands for Daily Light Integral, is the total amount of photosynthetic light (PAR) delivered to a plant over a 24-hour period.
The amount of light a plant receives during the measured time period is important for proper growth and optimal photosynthesis.
How much light depends on each plant type and the growth stage. DLI and quality of light can factor into all aspects of a plant’s physical characteristics, including rooting, branch length, budding, flowering, etc.
DLI is calculated using the formula of the accumulated PAR over one square meter in a 24-hour period, expressed as mol m-2 d-1.
The total amount of light needed by any plant depends on several factors: growth stage, temperature, water, humidity, and other factors. However, many researchers have developed some ideal ranges that are applicable to most plant types.
The following is a compilation of data from various experts regarding the amount of DLI required by differing plant types at various stages of growth.
Growers should consider delivering this minimum DLI to their plants.
Understanding just how much light your crop requires at each growth stage could save you money. How? Using controlled LED lighting, within your operation, you can deliver the right amount of light at the opportune time.
Supplemental or primary lighting with LED technology allows the grower to control the timing and delivery of light to their crops. Additional light may increase yield and growth; thus the grower can determine their potential increased harvest with the cost of extra lighting. Growers should push their crops to their maximum yield potential.
With the development of dimmable and color ratio controlled lighting through the GROW3 system, the grower can consider scheduling and light levels adjustment to match the minimum required DLI levels for their plants. In addition, the GROW3 system allows the grower to adjust the levels and color of delivered light throughout each growth stage, saving energy. Want to know more? Ask us how.
