The Perfect Spectrum Matching the Sun? CCT vs CRI

Is the Mint White Series (using Samsung EVO diode) the perfect cannabis spectrum? Probably not (maybe the best) but does get very close to matching the daytime sun’s kelvin temperature. 🌞⁣⁣
⁣⁣⁣⁣
As we move to what we believe is the optimal cannabis spectrum…. the Mint White series gets very close to what nature intended. ⁣

When it comes to plant growth, both CCT (Correlated Color Temperature) and CRI (Color Rendering Index) are important factors, but they have different impacts on plants.⁣⁣⁣⁣
⁣⁣⁣⁣
CCT refers to the color appearance of light and is measured in Kelvin (K). It indicates the "warmth" or "coolness" of light. Lower CCT values (e.g., 2700K-4000K) are considered warm or yellowish, while higher CCT values (e.g., 5000K-6500K) are cooler or bluish. CCT plays a crucial role in regulating photoperiodism and controlling plant growth stages.⁣⁣⁣⁣
⁣⁣⁣⁣
CRI, on the other hand, measures the ability of a light source to accurately render colors compared to a reference light source. It is represented on a scale of 0-100, with 100 indicating the best color rendering. While CRI is essential for human perception of colors, 𝐢𝐭𝐬 𝐬𝐢𝐠𝐧𝐢𝐟𝐢𝐜𝐚𝐧𝐜𝐞 𝐟𝐨𝐫 𝐩𝐥𝐚𝐧𝐭 𝐠𝐫𝐨𝐰𝐭𝐡 𝐢𝐬 𝐥𝐢𝐦𝐢𝐭𝐞𝐝.

⁣⁣⁣⁣
Therefore, CRI is not the most critical factor for plant growth, and some lighting solutions designed specifically for horticulture may have lower CRI values. ⁣

In summary, CCT is more relevant for plant growth as it affects photoperiodism and influences different growth stages. CRI is of lesser importance for plants, although it remains significant for human visual perception. When selecting lighting for horticultural purposes, it's essential to consider both CCT and the specific light spectra (wavelengths) required for photosynthesis rather than solely relying on CRI.
