can you grow weed from seeds in bag

Fill a small seedling pot with an unfertilised or “light” potting mix. Poke a small hole about 1cm deep in the middle and place your seed inside. Cover lightly with soil. Water the soil and cover the seedling pot with clingfilm to lock in moisture. Seeds should germinate in a few days.

Heat stress can lead to growing problems both indoors and out.

3. NOT USING THE RIGHT SOIL

People love their weed plants, so they think giving them more must be a good thing. But alas, it’s not. Overfeeding can lead to nutrient burn, or worse, nutrient lockout caused by accumulated minerals in the soil. In this case, you’ll need to flush your soil with water and start again with your feedings to return the pH to an ideal window. In short: don’t overdo it on the nutes!

Most cannabis soils, with the exception of special soil mixes used for propagation and seedlings, are pre-fertilised. This way, you won’t have to administer nutrients until several weeks into the grow. In fact, you may only need to feed nutrients when your plants start to flower. If for some reason your growing medium isn’t pre-fertilised, you will have to give nutrients to your plants from the beginning.

Without light, weed plants die extremely quickly. They depend on light to create vital carbohydrates, which are required as an energy source. As photons hit their leaves, small organelles known as chloroplasts convert light into energy-rich sugars.

If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.

Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.

How weed seeds work

Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.

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

The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
