In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
Are you ready to grow?
With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.
Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.
Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.
Once you’re confident your plants have recovered from being transplanted, start feeding them with a mild nutrient solution. An NPK ratio of 4:2:3, for example, is a good starting point for plants just beginning to veg.
This phenomenon, known colloquially as “damping off”, is caused by fungi like Pythium, Botrytis, and Fusarium. While these fungi can lie dormant in soil, they grow and thrive in overly wet conditions. Overwatering and high humidity, for example, are some of the most common causes of damping off.
We’ve all been there; your seedlings look perfectly healthy, then suddenly you find them slumped over the edge of their containers. Within 24 hours (or sometimes less), they’ve shriveled up and died.
HOW TO PREVENT DAMPING OFF
Unfortunately, by the time your seedlings show the first signs of damping off (a limp and discoloured stem), there’s nothing you can do to save them. We just recommend removing the affected seedlings from your grow room or propagator ASAP to avoid spreading the fungi.
At RQS, we’re big fans of organic cannabis gardening. No amount of chemical nutrients could ever compare to the complex mix of microorganisms that exist in organic soil.
Cold temperatures, on the other hand, can freeze a seedling’s cells and affect its ability to transport and use nutrients, water, and oxygen. This will result in stunted growth and eventually death if not dealt with properly. Wilting foliage, slow growth, and poor plant turgor are some signs that the temperature in your grow room or propagator is too low.
A shallow hole could mean the marijuana seeds will dry out. If you are planting seedlings outside, shallow holes could introduce the risk of them getting disturbed in some way. An easy way to ensure the pencil or pen goes down far enough is to put it next to a rule. You can mark the correct spot before inserting it into the soil.
Burying a weed seed too far into the soil can negatively impact its growth. The recommended depth of the hole is 2 to 2.5 centimeters. It is the best length because seedlings have roots that are 1.5 to 2.5 centimeters long. A couple of centimeters ensures they have enough space.
Step 3 — Place the Cannabis Seed in the Dimple
Some growers use the damp paper towel method for the germination process. Sometimes, the newly-formed root of the seed can get stuck to the paper towel. The first instinct is to pull it loose carefully, but the action could potentially damage the plant. Instead, spray it with some water to encourage the root to let go of the paper towel.
Once you have the best pot or cup for your germinated seed, fill it with soil. After planting is done, the root system should always grow downward as the plant gets bigger. Therefore, you do not want to put in too little. The roots still need enough space to absorb nutrients.
The dimple should be about a couple of centimeters deep. If you are using a pencil, an easy way to measure is by making the tiny hole erasure-deep. Like any plant, you do not want to plant the weed seed too far in the growing medium.
