Growing cannabis at home isn’t rocket science.
Since cannabis is a “weed,” it requires little attention — rule of thumb is to avoid overwatering and over-fertilizing — although some basic conditions must be met if you want to obtain a product of decent quality.
“The secret of growing anything is the soil, the light and the food,” says Tom Neumann, an Alberta-based licensed medical marijuana grower.
Neumann runs TheGrowShow.ca, a website hosting Twitch streams that give tips to hopeful home growers. Much like basic gardening, all you need to get started is good seeds. If you’re growing outside, you will want to start early in the spring, ensuring your plants get as much sunlight as possible until they flower late in the fall. You will be at the mercy of the elements, but Neumann said his plants are surprisingly resilient, even in northern Alberta weather.
Growing inside is a bit more complex. A timed lighting apparatus (12 hours on, 12 hours off) is critical to grow the plant and get it to flower. Consider a high-intensity discharge lighting system, or HID, for best results. You will also need an exhaust fan with a carbon filter to limit the smell.
