Begin by making very sure that any problems you are experiencing with these strains are not due to grower mistakes! Common mistakes include:
- using nutrients intended for use in the vegetative period. If you're using these, the plant will not get the necessary nutrients to start producing flowers. Solution: switch to flowering nutrients immediately.
- using a 24/0 light cycle. The fact that auto-flowerers are not photo period dependent, like regular cannabis plants are, does not mean that being bathed in light 24/7 is right for them. Many growers make the mistake of thinking plants need to be exposed to light as much as possible to grow bigger, when the dark period is actually when plants use that built-up light energy to develop roots and leaves. (obviously, using a dark period also means far lower electricity bills and heat output). Solution: switch to an 18/6 or even 16/8 light cycle.
- using too high temperatures. Tying in with the issue above - if plants get too hot, flowering may be affected. Slightly lowering the temperatures simulates the ending of the growing season, thus stimulating flowering. Solution: carefully lower those temperatures.
