how to germinate immature seeds

Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Pros and cons of using cannabis clones

Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.

A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.

If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.

Leaving the seeds in water for 24-48 hours is called ‘soaking’ and many growers prefer it prior to any chosen method of germination. Stronger and healthier seeds will sink sooner, seeds that remain floating are either not mature enough or may require a little help to start germinating. You can gently tap them with your fingers and that will make them sink, the ones left floating probably won’t germinate.

Some growers like to ‘winterize’ the seeds before they start with the germination. Winterization is a process that happens naturally outdoors – as plants mature and they develop seeds that will enable the next generation to grow, they tend to fall off the dying plant and as winter comes, they are covered in snow and in low temperatures during the winter before starting a new life cycle in the spring. So to mimic that behavior, growers expose seeds to lower temperatures, usually putting them in the fridge for a couple of days prior to germination. It helps activate the hormones and enzymes that signal the plant that time for a nice start is coming.

And finally we come to the transplanting stage. This process is very important and growers should be gentle and careful while transplanting young seedlings to grow medium. Do your best not to hurt or injure the seed or the root. Make a little 2-3 cm hole in soil and place the germinated seed with the taproot down. Top side of your seed should be just below the surface, about 1-2 cm in. Make sure that your seed is in nice contact with the medium and cover the top of the seed lightly with medium.

The histological and histochemical changes during seed development of C. macranthos were investigated in detail.

Modified Harvais medium supplemented with potato or banana homogenates was suitable for the growth of seedlings.


Cypripedium macranthos is a lady's slipper orchid with high horticultural value. We document a reproducible protocol for asymbiotic seed germination based on a defined time frame. The optimum germination percentage was obtained from immature seeds collected at 6 weeks after pollination (WAP). At this time, the embryo reached the early globular stage. As seeds matured, the germination percentage declined sharply. Histological observation revealed that two distinct layers of seed coats enveloped the embryos tightly at maturity. The histochemical staining by Nile red and TBO indicated the presence of hydrophobic substance and phenolic compounds (e.g. lignin and cuticular material) in the seed coats. These features reflected the strong hydrophobic nature of seed coat that may cause the seed dormancy. Among the surveyed media, the modified Harvais medium was the optimum for germination. Among the surveyed organic supplements, potato homogenate (50 g l −1 ) or banana homogenate (25 or 50 g l −1 ) was suitable for the growth of seedlings.

The accumulated hydrophobic materials, such as phenolic compounds in seed coats, contribute to the water-repellent nature.

The optimum germination was obtained as the immature seeds were collected at 6 weeks after pollination and sow on modified Harvais medium.
