So I made the big jump into flowering last night, well actually it will be Tuesday morning at 9am. I am following one of Roberts guides and giving my plants a jump start with 36 hours of darkness. Here is the procedure word for word from Roberts guide.
Jumpstarting your flowering period
Although most people prefer to change their lighting schedule to begin the flowering process, it can actually be given a head start in another way. Take advantage of your completely dark grow room by actually keeping it completely and utterly dark for an entire 36 hours.
This will drop the Phytochrome Far Red amount significantly — more so than if you switched it to a 12/12 schedule from the beginning. The idea behind kick-starting the process in this way is to give a loud and clear signal to your plants that flowering season has begun.
Once the 36 hours are complete, begin with the 12/12 lighting cycle. The results of doing it this way can be significant. It is also important to remember the nutrients needed for this change in life cycle — your plants no longer need high nitrogen fertilizers, but rather need more phosphorus for the flowering period. Potassium can also help with faster bud growth.
Let the good times Roll
