Sudden extreme changes in temperature can affect a plant’s growth and yields, such as a sudden cold snap, which can slow a plant’s growth, or a heatwave, which can dry out a plant.
Using the above yield estimate of ¼ lb., or 112 grams, for one medium-to-large-sized indoor plant, if you smoke one gram a day, that one plant would last you 112 days, or just under four months! Two grams a day would last you just under two months, and half a gram a day—or an eighth a week—would last you eight months.
Note that these are estimates. When growing outdoors, plants can usually get massive because they aren’t restricted to space—it’s not uncommon to get closer to a pound a plant or more.
Be sure to prune your plants to remove dead leaves and buds, and branches that won’t turn into sizable buds. Clearing out plant matter will allow the quality buds to get more light.

Weed typically likes warm, temperate climates—think of Northern California’s Emerald Triangle region—but certain strains thrive in different temperatures. Traditionally, indicas like cold, dry climates and sativas like warm, humid climates.
A weed plant will lose about 75% of its weight to moisture loss and trimming after being cut down. A considerable amount of moisture leaves the plant during the drying process, and trimming removes all the stems, branches, fan leaves, and trim from the plant.

Certain weed strains grow big or tall or are high-yielders simply because of their genetics. Traditionally, indicas grow short and stout, and sativas grow tall and lanky. That’s not always true across the board, but it is a good rule of thumb.
While most, if not all, medical and recreational farms cultivate cannabis from seeds, guaranteeing that their plants are free from viruses, most home growers, even those with experience, typically begin with clones — essentially trimmed pieces of female cannabis plants that have been rooted in separate pots. “When most people think of cannabis — you know, what you smoke — they’re thinking about the flowers of female plants,” Lipton said. “When you grow from seeds, half of them will be males. If you’re only going to do one or two plants, you don’t want to waste your time with that stuff.” A clone sourced from a dispensary or a knowledgeable friend guarantees that the plant is female and will eventually produce bud pending proper care. “You can get up to four ounces off the right plant — if you know what you’re doing.”
Know the law.
Temperature: 68 to 78 degrees Fahrenheit. “A tool you should always have is a little temperature gauge,” Lipton said. “They call them hygrometers. They’re cheap and tell you both the temperature and the humidity.”
Plant and maintain the vegetative cycle until the plant is mature.
After 55 to 60 days, growers begin paying close attention to their plants’ trichomes — the small, bulbous fibers that develop around the flower of the female plant. “Those trichomes will turn from clear to amber,” Lipton said. “They kind of look like red hairs. You know it’s time to harvest when about 10 to 15 percent of the trichomes turn that color.” On average, cannabis plants have a five- to seven-day window of peak harvest time.
