best way to start weed seeds

Soak the seeds in a solution of water with commercial rooting solution and hydrogen peroxide (H202) for 12 hours. The hormones in the rooting solution stimulate germination and encourage root growth. Use rooting solution according to instructions for softwood cuttings and add hydrogen peroxide at the rate of one part to 200 (.5%) to sterilize the solution, preventing infection. Drugstore peroxide is a 3% solution; if it’s used, add it at the rate of one part H202 to five parts water. Compost tea can also be used as a soaking solution to create a biologically active community around the seed.

A seed is the distillation of a plant’s essence. It contains the blueprint for life, which it holds in storage until it senses environmental conditions favoring survival of a new plant.

Marijuana germinates best at room temperature, around 72° F in a consistently moist environment. The first visible sign that a seed is germinating is a slight enlargement resulting from water absorption. Then a small opening appears along the seed’s seam as the root emerges. The root continues to elongate, growing downward, as the stem makes its appearance. It stretches out in the opposite direction of the root and uncurls, revealing two embryonic leaves called cotyledons. The seed case is now an empty shell and it may hang from one of the cotyledons until blown or rubbed off. Only a day or so has elapsed between the first sight of the root and the appearance of the cotyledons.

Methods for germination

You can see the pericap of the seed still on top of the embryonic leaf, the cotyledon. The first true leaves are visible above the cotyledon. Cannabis seed photo by Professor P of Dynasty Genetics.

After soaking you can place the seed between a thin wet cloth or paper towel on a plate with a clear cover or plastic wrap. When the root emerges, plant it by first poking a hole in the planting mix that is long enough for the entire root area to be covered. Then gently place the seed and pat it so the root makes contact with the medium. The other method is to plant the soaked seed into the medium before it germinates. Place it ¼ inch deep in sterile commercial planting mix. Moisten the mix with water adjusted to a pH of around 6. Keep it in a bright space with high moisture. If the space is dry, place a tall cover over the container to reduce evaporation. Keep at room temperature. If the air is cool, use an electrical tray warmer and cover.

Only a day or so has elapsed between the first sight of the root and the appearance of the cotyledons.

Once it has made contact with the requisite amount of moisture and proper range of warmth, the seed starts the process of germination. A cascade of chemical reactions results in the rapid growth of the embryo plant, which had been kept in suspended animation.

This article explains how to correctly germinate your cannabis seeds, covering everything from optimum temperatures, to potting your seedlings and transferring them outdoors (or inside under lights).

Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.

Step 1. The setup – How to germinate cannabis seeds

Place the plates somewhere warm (21ºC) and away from direct light.

Check the seeds every day to ensure that the tissue does not dry out. Spray the tissues with water if necessary.

The best way to germinate cannabis seeds requires only two saucers or plates and some moist tissue. Here is a step by step guide.

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

Immature seeds tend to be light in color and have a soft outer shell.

What are feminized cannabis seeds?

Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.

Most seeds that you will buy are regular seeds as described above, but here are a couple more types.

Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.
