Warm Spectrum Light Triggers Plant Flowering

If you’re growing fruiting crops, you can switch plants or lamps to a warmer spectrum (more red light) once you’ve bumped them up to larger pots to trigger stem elongation and flowering. If you need your plants to flower and they require a specific photoperiod to do so, they will require red light.

Cannabis will need close monitoring of lighting to trigger the plants into flowering.
