flowering. During this time the days get shorter and the nights get
longer. When this occurs the plant is under 12 hours of light and 12
hours of darkness. When this 12/12 PHOTOPERIOD occurs the plant
is naturally stimulated to flower. If the 12/12 continues then the plant
will produce its flowers. As long as 12/12 continues the flowers will
grow larger and more plentiful. This is part of the cannabis plants
evolution and how it has taught itself when to flower. Naturally as a
grower we want lots of flowers so we need to put the plant through a
light cycle of 12/12. This means that we must turn our lights on and
off at these given ratios.
During pre-flowering you will either manually turn on your
lights for 12 hours and turn off your light for 12 hours everyday or you
will use an automatic timer. If your light comes with a timer set the
timer to do this. Throughout the 12 hours of darkness it is best to keep
your grow area as dark a possible. A small desk light at the other side
of your room will cause your plant not to react properly to 12/12 which
will result in continued vegetative growth. In fact any light that
penetrates the darkness will stop your plants from flowering properly.
That means that your grow room must be sealed to the point where it
is completely light proof. If you want to learn how to do this perfectly
then I suggest that you read up on 'Photography Dark Rooms', either
on the Internet or in your local library. Photographers use common
items that can be bought in most hardware shops to make their film-
processing rooms light tight. If you can replicate their ideas (basically
a thick black screening around the doorframes or any open light
points) then you will have a great system for flowering plants in. I
