Choosing Color Temperature (CCT)
Color temperature defines the color appearance of a white LED, the relative weighting of different wavelengths within the visible light spectrum. Correlated color temperature (CCT) is defined in degrees Kelvin; a warm light is around 2700K, moving to neutral white at around 4000K, and to cool white, at 5000K or more:
· Dual Veg/Bloom Spaces: 3500K
· Dedicated Bloom Spaces: 2700K
· Dedicated Vegetative Spaces: 5000K
We offer SolStrips in 2700K, 3500K and 5000K CCT spectrums because each will veg, bloom or veg and bloom cannabis very well on their own, or can be combined to build custom spectrums tuned to the specific grower's needs.
For most applications, 3500K is a great spectrum, close to perfect for taking plants from veg through bloom. It is rich in the red wavelengths which are critical to plant growth and flower production, while delivering a significant amount of blue light that has been found to be a critical stimulator of photosynthesis in combination with red light. I recommend it 70-80% of the time, as it will deliver outstanding results across a wide range of applications.
For dedicated veg spaces, 5000K is perfect - it keeps plants healthy, short and squat, stimulates root development, and is slightly more efficient than warmer spectrum strips.
Conversely, for dedicated bloom spaces, 2700K delivers fantastic results equaling and exceeding the performance of the best HPS bulbs in stimulating flower production and inducing maturation. Perfect for bringing heavy indica-dominant strains to full maturation.
That said, I've seen very good veg-through-bloom results with 5000K (especially with sativa-dominant strains) and 2700K, and know that different situations require different solutions, which is why we offer SolStrips in three different color temperatures.
