To facilitate a plant’s growth of buds or ‘flowers,’ a plant simply needs 12 hours of darkness and 12 hours of light, daily.
As fall approaches, in nature, the color of the Sun is drenched in hues of reds, oranges and yellows due to the position of the Earth, the Sun, the distance from Earth to the Sun, and a myriad of other reasons.
So, plants in nature hormonally adjust to the change in seasons, with the color of the Sun being a primary indicator that fall is coming, and it’s time to bloom. That being said, plants respond well in flowering to bulbs in the 2,700 Kelvin range, commonly called “Warm White” bulbs.
These bulbs can be found in a wide range of wattage, with 23 to 42 watts being common choices for those flowering Cannabis with CFLs. For best results, mix ‘Warm White’ bulbs with ‘Cool White’ bulbs (or ‘Daylight’ spectrum bulbs).
You will in turn give your plant(s) as many spectrums of light as possible, increasing your chance of the particular strain getting exactly the light IT wants for optimal growth and bloom.
Although flowering Cannabis with CFLs has no bearing on when your plants will begin to bloom and grow luscious, sticky buds, you definitely want to max sure you use the correct bulbs, preferably from well-known manufacturers, and tested for long life.
