rotted marijuana seeds

One of the biggest factors inhibiting seeds from sprouting is fungus. Old, reused soil that isn’t sterilised is likely to contain mould and other harmful organisms like bacteria and insects.

Believe it or not, hemp seeds are a major component of many types of birdseed! That’s right; birds love them just as much as you do. But birds aren’t the only critters that would love nothing more than to chow down on your seeds.

5. NOT USING NEW OR STERILISED SOIL AND POTS

Handling your cannabis seeds with bare hands can contaminate them with all kinds of nasties like bacteria and fungus. Unfortunately, seeds and seedlings are especially vulnerable to these types of harmful pathogens.

Likewise, when temperatures are too low, this can introduce a whole host of its own problems, including inhibiting seeds from sprouting. Colder temperatures also increase the risk of other plant diseases. What to do about it? If you want to grow outdoors, don’t set plants outside too early. Instead, germinate indoors and allow your seedlings to grow for a few weeks.

Likewise, if your seeds are too close to the surface, there is a risk they’ll dry out before sprouting, or the seed will emerge but can’t shed off its cap. The happy medium is to place your seeds about 0.5–1.0cm deep and just lightly cover them with soil.

To an untrained eye, the beginnings of powdery mildew might look like young trichomes. If you suspect it, use a magnifying glass to examine your buds—you’ll see a stark difference between white mold and beautiful trichomes.

Bud rot is a type of mold that develops in the dense cores of cannabis buds. It starts on the stem inside of the bud and spreads outward, and it’s difficult to detect in its early stages. It typically occurs on plants in the flowering stage.

Plant roots interact directly with mycelium, the substance mushrooms sprout from. Mycelium helps make nutrients available to plant roots and helps roots find water. In exchange, a plant sends down carbon, helping mycelium grow and expand its own network.

Diagnosing and treating root rot on marijuana

If you do find bud rot, everyone trimming needs to start looking for mold. Anything that is at all questionable should be set aside to be inspected with more scrutiny.

Most important of all, protecting plants from excessive moisture is key in the battle against bud rot. Also, watering plants in the morning can help prevent humidity in the garden when the sun goes down or when lights turn off later in the day.

When growing outdoors, if tilling soil, make sure to keep off the soil as much as possible to prevent it from compacting, which prevents oxygen flow.

Efforts to prevent bud rot do not stop once buds have been harvested. Mold can also occur as cannabis buds dry and cure. Here are a few tips:
