Figure 7.4 – Here is another shot of the condition. The male pods are clearly visible.

Early induced flowering is not technically forcing your plant to flower. If you force flower on one strain that has not pre-flowered it will flower at roughly the same time as an exact copy of the same strain which has been flowered only when the pre-flowers appear naturally. Force flowering simply acts by stressing the plant into a crisis condition.

– Most cannabis plants can be kept alive for up to 10 years by simply keeping a light on the plant at all times. These plants will grow to a certain height and then form into a bush. It will then eventually stop producing branches and will spend the rest of its life growing new leaves to replace the old ones.
12/12 is easy to explain. Cannabis plants grow outdoors naturally between the months of April to October/November. This means that towards the Sept/Oct/Nov dates the plants will be in 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.
Figure 7.7 – This is a female plant by BigIslandBud.
During the strict cycle of 12/12 she will eventually reach a peak period of flowering. Along with the flowering cycle the plant will also fill out more. More leaves, more branches and more flowers. Your plant will start to almost take the shape of a Christmas tree. The lower fan leaves will be stretched out to the max in order to receive the most light. Running upward in a cone shape she will get tighter with floral and leaf development.
If you have pre-flowers and want to flower you only have to do one thing. You must put your plants under a 12/12 schedule.

Each strain does have their own flowering times and each strain also may have a different colour tint when they reach a flowering peak.

By now you have managed to set up the basic environment in which your indoor plant will grow. You have your plants in some pots under a grow light with some

Did you know that pre-flowers/calyxes/flowers are actually what holds seeds if your plant gets pollinated? Once pollen touches the white pistils, the pollen gets delivered to the inside and a seed starts forming!

Variability of Plant Sex (How to Increase Ratio of Female Plants)
I’ve also noticed that sometimes (though not always!) the stipules on male plants seem more “leafy” and less “pointy” than stipules on female plants (the stipules are the green hair-like growths near where pre-flowers show up). However, this is just a generality, and should be used together with other factors to determine if a plant is male! There are definitely male plants with pointy stipules and vice versa, but it’s sort of a general difference.

This male plant was only 3 weeks when it made its first pre-flower. Notice how tiny it is compared to the giant-sized thumb! Often it’s unclear what the sex is when a pre-flower is this small (unless you’ve got a lot of experience) so if you’re not sure, it’s a good idea to wait and see how it develops, just in case.
Cannabis Pre-Flowers Are Small Versions of Adult Flowers. These reveal a plant’s sex.
Unfortunately, due to the fact that different environmental conditions during the first part of life can alter the sex, you can’t look at seeds and definitively know one way or the other whether the plant will end up being female because even the plant doesn’t necessarily “know”.
When starting with “feminized” seeds (which you can usually only get from a breeder), all your seeds should end up being female, so determining male from female isn’t very important. Learn more about buying seeds (including feminized seeds) from breeders online.

  • Healthy Mom – Only grow seeds from a vigorous, healthy mother plant who never showed any signs of herming or male pollen sacs (seeds are more likely to grow pollen sacs if the mom plant had a tough start in life, or hermed during the flowering stage)
  • Cool Temperatures – Give seedlings slightly cool temperatures (65-75°F day and night) and avoid excessive heat
  • High Humidity (50-70% RH)
  • Short but not too short days. Keep consistent day and night periods with no light interruptions at night, and days should be 14-18 hours long (between 14/10 and 18/6) for the first few weeks
  • Blue light. Always start seeds under a vegetative grow light (something with plenty of blue like a Metal Halide or a 6500k CFL/T5/fluorescent)
  • Avoid Deficiencies – Make sure to provide plenty of Nitrogen and don’t let seedlings become nutrient-starved or run into other types of deficiencies
  • Prevent Stress, especially heat or light stress during the first few weeks
  • Happy Roots – Avoid over (and especially) under watering
