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.”

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.”

Find a healthy clone.

Space: 3 x 3 x 5 feet, minimum. “The bigger the space, the better. With all the lights, closets get hot,” Lipton said. That said, closets help growers control light pollution when the plant is in its flowering cycle — one of the main reasons home growers favor them over larger spaces, such as living rooms. “If you have a spare bedroom, or a basement even, you can just use that and close the door,” Lipton said.

Relative humidity: 30 to 45 percent. “If you live somewhere humid, you’re probably going to want to buy a dehumidifier,” said Lipton. “In Boulder, we sometimes have to add humidity.” At home, that can be done with a reliable humidifier.

Know the law.

Another layer to consider is that cannabis cultivation must happen “out of plain sight.” “You can’t have any odor. If it’s offending people in the neighborhood, then it’s an issue.”

Ensuring your plants get the right nutrients is probably second only to lighting in terms of importance. Proper nutrient selection and application are among the most critical factors in growing premium-grade cannabis. While weed is resilient, growing it in sub-optimal conditions means you will miss out on yield and potency.

A hermaphrodite cannabis plant will produce flower that’s full of seeds, ruining your chances of a decent yield of smokable buds.

By “small,” I mean nothing more than a few plants at most. You can start with just one or two plants. There’s an inevitable learning curve involved with growing weed indoors and you’re bound to make some mistakes.

Step 5: Be an Artist! [And Choose a Cannabis “Grow Medium”…]

As a potential first-time grower, getting started is the biggest roadblock you’ll likely face. First, you have to find the right place to cultivate and obtain the proper growing equipment. Then, you need to buy cannabis seeds and spend a lot of time checking and maintaining your crop.

For example, most growers use one of two main types of HID lamps/bulbs depending on the developmental stage. Metal halide (MH) bulbs are best during vegetative growth. High-Pressure Sodium (HPS) is the preferred option for the mature flowering stage. If you can only afford one, choose HPS as they are much better for flowering and are more efficient on a ‘watt-to-light’ scale.

3 – Keep Your Grow Space as “Light-Sealed” as Possible

This is when you can extract the male plants and eliminate them. Male plants will have what look like little clusters of bananas; these are the pollen sacs. Female plants will have sharper early-stage calyxes with white hairs (pistils). Those growing from female clones or pre-purchased feminized seeds should have no concerns about male plants.

You can get these macronutrients pre-packaged in liquid or powder form (if you’re using an un-supplemented soil mix). However, a lot of organic “super soils” already contain them in sufficient amounts.
