Among the early signs that your female has been pollinated is that her bracts become larger. Bracts are small, leaf-like structures that protect the female’s reproductive parts. These are the sites from which the flowering buds appear. Do not confuse the bracts with calyxes.
Pollination of your female cannabis plants will make them produce seeds and spend less energy on producing quality buds. But when you recognise the signs of pollination early, you can avoid putting time and resources into a poor harvest.
HOW TO AVOID POLLINATION OF YOUR FEMALE PLANTS
Obviously, no one wants to smoke seedy weed. When you grow cannabis and learn how to identify male plants and signs of pollination, you can remove these plants to save your remaining females. Likewise, recognising a pollinated female early allows you to start again before it’s too late, rather than finishing a grow that will only result in a poor-quality harvest.
Another indication of pollination can be the colour of her pistil hairs. When a female has been pollinated, the previously white hairs will soon shrivel and become darker.
The alternative to regular seeds is feminized seeds. These are seeds produced by plants treated with a solution of silver or other chemicals to inhibit the production of ethylene, which is part of the sex-determination pathway. Treated plants produce pollen sacs containing only female genetic material. When these plants pollinate other female plants, nearly 100% of the resulting seeds grow into female plants.
Beginning weed growers often ask how many seeds they need to put in a pot to grow a single plant. It’s a common question because many garden plants, like herbs and lettuce, have tiny seeds that are planted by dropping them into the same hole, while others, like cucumbers and melons, have large seeds that need to be planted individually and spaced far apart.
Seed Quality And Germination Rates
When you purchase seeds to grow marijuana, you’ll need to choose between regular seeds and feminized seeds. Regular seeds can grow into male or female plants, but only female plants produce the buds that you will eventually harvest. Thus, if you’re buying regular seeds, you’ll need to germinate several seeds to make sure you get at least one female plant. And if you fail to catch and remove a male plant in time, it could fertilize a female plant and significantly reduce its potency.
Another factor affecting how many seeds you need to plant is the quality of the seed. Fresh seeds, for example, tend to have higher germination rates, meaning it takes fewer seeds to produce a single healthy plant. Most of the time, you can plant fresh seeds directly in the soil, while older, dried out seeds will need to be germinated first. To do this, soak each seed in a wet paper towel and keep it in a warm and dark environment until a tap root appears. Once the seed has sprouted, or popped, you can transplant it into a pot or plot of soil.
Furthermore, it’s easy to find conflicting recommendations from experienced marijuana growers who have developed different methods that work well for the types of seeds they grow. In general, however, the answer to the question is simple: you only need to plant one marijuana seed per pot or per square meter of growing space to get a big, leafy plant.
Pollen is used to fertilize female cannabis plants and create seeds. In the wild, cannabis pollen is transported from male plants to females via the wind. However, in a manmade grow op growers will collect the pollen from males manually and then apply it to the females when they’ve started developing flowers.
When it comes to storing cannabis pollen, moisture is your worst enemy; if your pollen gets wet it is literally useless.
WHAT IS CANNABIS POLLEN?
You can then move your pollinated female plant out of the room and back into another grow environment. Just make sure to keep both your male and pollinated female as far away as possible from the females you don’t want to pollinate.
As we mentioned earlier, cannabis pollen is typically used by breeders and expert growers to create new strains or seeds. They do this by harvesting pollen from their male plants and then applying it to female plants that are about 2-3 weeks into their flowering cycle.
Cannabis seeds develop in the flowers of the female plants after about 4-6 weeks from pollination. You will see the seeds starting to form in and around the pollinated buds.
