How does overwatering affect cannabis plants?

Overwatering can cause root rot, which can lead to a range of problems, including reduced growth, decreased yields, and increased susceptibility to pests and diseases. It can also cause the plant to become oxygen-deprived, leading to further stress and damage.

What are the most common mistakes that lead to overwatering?

One of the most common mistakes is watering cannabis plants on a schedule, rather than checking the soil moisture levels. Other mistakes include using pots with poor drainage, watering too frequently, and not adjusting watering schedules according to changes in temperature and humidity.

How can I prevent overwatering my cannabis plants?

To prevent overwatering, it's essential to check the soil moisture levels regularly, using a moisture meter or your finger to test the soil. Make sure your pots have good drainage, and avoid watering too frequently. Also, adjust your watering schedule according to changes in temperature and humidity.

What is the ideal watering schedule for cannabis plants?
