how to make a marijuana plant produce seeds

When sexing begins, male pollen sacs will develop instead of female calyxes and pistils. Male plants mature much faster than females, and viable pollen can be expected within 3–4 weeks once the plant has been sexed. Some growers will spray until the plant shows sexual growth, just to be sure the method has worked. Make sure these plants are well-isolated from any flowering females. A burst pod can release millions of pollen spores, and it only takes one spore per hair to create a seed.

Colloidal silver is by far the easiest to source or make. It is non-toxic, non-caustic, and can be bought from a pharmacy or easily online. The other solutions can be dangerous, difficult to get a hold of, and expensive—except gibberellic acid, which can be found in nurseries, but is not as effective as colloidal silver. But if you want to watch some freaky plant growth just for the fun of it, give gibberellic acid a try. It is a growth stimulant and makes plants stretch and stretch.

Treat feminized seeds as you would any other seed from germination to veg, and veg through flower. Observation is where it’s at now, you want the best plants for your garden. Ideally, setting up a separate vegetation/flower space where a number of plants can be grown lets your standard grow space continue with uninterrupted production.

TECHNIQUE 2: RODELIZATION

There are a number of harvesting methods employed to catch pollen.

Plants can be induced to grow male sex organs as late as four weeks into flowering. Though spraying one week prior to the light changeover is recommended for clones. If a plant grown from seed is being used, wait until the plant has sexed before spraying so you can be sure it is female.

Wouldn’t it be sweet if it was possible to grow all females from seed, every plant, every time?

Once the plants have been sprayed with colloidal silver and the pollen is collected, they are write-offs—86 them and don’t smoke them. Giving them a thorough rinse will not work. The colloidal silver is a systemic treatment absorbed into the plant through the foliage and not a topical application. Be safe and bin them.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.

Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.

So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.

When we talk about cannabis it’s easy to get caught up in the beautiful females that produce those cannabinoid-rich buds we all love and treasure. In fact, we have become so focused on the female cannabis plants that it’s almost considered a bad omen if a plant happens to turn out male.

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.

WHAT IS CANNABIS POLLEN?

Pollen is fine powder that usually has a golden yellow colour. It consists of tiny microscopic grains excreted from the pollen sac on male plants.

But it’s important to remember that male cannabis plants are just as important as their female counterparts. Male cannabis plants produce pollen like other male plant varieties which germinate female buds to create seeds.

In order to pollinate your plant you’ll want to apply your harvested pollen onto the bud sites (usually located where leaves meet the stem of a plant) using a brush. This will cause the buds to develop seeds which can be collected and grown in the future.
