marijuana seed only 1 leaf

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.

A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.

Cannabis seeds vs. clones

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.

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.

Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.

Mycorrhizae ultimately act as an extension of the root system. Not only do they break down organic matter to release nutrients, but they also transport these important molecules from areas plants could otherwise not reach. Ultimately, mycorrhizal fungi play a fundamental role in plant nutrition and soil biology and chemistry.

This fusion between plant and fungi occurs in the rhizosphere, or root zone. The mycelium forms a sheath-like structure around the root tip that surrounds plant cells in the root cortex. Threads of hyphae—individual strands of mycelium—extend out into the soil where they break down organic matter and even connect one plant to another, forming a biological internet.

Mycorrhizal fungi participate in a give-and-take relationship with cannabis plants. These species form networks of thin, hair-like filaments in the soil—known as mycelium—and produce enzymes to break down organic matter.


After liberating nutrients from the substrate, the mycelium uptakes and shuttles them around to plants. Because cannabis roots aren’t capable of this impressive function themselves, they have to “bargain” with the mycelium to access these nutrients. Luckily, plants produce sugars during photosynthesis, and transport many of these molecules down into the roots. Here, they swap these energy-rich exudates for the nutrients they need to fulfil important physiological functions.

Without a doubt, cannabis claims the title as one of the most beautiful plants on Earth—from its glittering trichomes and signature leaves to its complex root system. Many growers frequent their grow rooms just to stand in awe at what grows before them.

Although not genetically part of the cannabis plant, mycorrhizae form a mutually beneficial relationship with cannabis roots that helps both species survive and thrive. These fungi appear all throughout nature and form a fascinating symbiotic relationship with up to 90% of plant species.
