These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.

Different lights produce different colors of light. Here’s a brief rundown of the most popular types of cannabis grow lights used for indoor growing.

Controlling temperature in your indoor grow room or cannabis garden can be achieved by manipulating these factors:

Remember, a common mistake newbie growers make is to overwater plants.

When growing weed indoors, you’ll likely have to add nutrients to your plants. You won’t need to add nutrients every time you water, but get on a schedule where you water every other time, or two on, one off.

A lot of people these days buy grow tents for their weed, but they aren’t necessary. You can grow in a closet, tent, cabinet, spare room, or a corner in an unfinished basement. Just keep in mind that you’ll need to tailor your equipment (and plants) to fit the space.

Examine the tops and undersides of leaves for pests or discoloration—spider mites live on the underside of leaves—as well as stalks and branches. Also, check the soil for pests.

Indoor climate

The main drawback is fluorescent lights are less efficient, generating about 20-30% less light per watt of electricity used; space is another concern, as it would require approximately 19 four-foot long T5 bulbs to equal the output of a single 600 watt HPS bulb.

Unlike outdoor growing, you aren’t tied to the sun and the seasons. You will be providing the entire environment the plants need to grow, including the grow medium—soil, rockwool, etc.—and regulating the amount of water and nutrients they receive, as well as controlling temperature, humidity, and more for them.

The beauty of starting seedlings in the opaque cups is that you can see the root growth. Poke some drainage holes around the cup bases. It’s quicker to do the drain holes with the cups in a stack. As you finish each cup, slip it in the other end of the stack or you’ll waste crumpled up cups. Mix the potting soil with enough sand to give the fluffy soil more body. Add water gradually, mixing well to moisten.

During the vegetative phase, leave the lights on 24/7 and as close to the leaves as possible without touching. If the lights are too high, the stems will grow weak and spindly. You want the plants to remain compact. When your plants really take off, they may grow an inch a day. Keep a sharp eye on the distance between the tops of the plants and the lights. Fluorescents are cool and won’t burn the leaves, but keep adjusting your lights upwards to stay ahead of the growth.

Germinating Cannabis

Throw a shovelful of manure in a bucket, fill with water, let it sit a couple of days and water with the tea. It worked fine for me. There are “hot” manures and “cold” manures. Hot manures have the highest nitrogen, but have to be aged. Cold cow manure has lower nitrogen but can be used hot out of the barn. Rabbit manure is cold, but some growers call it nitrogen on steroids. If slogging around in barnyards doesn’t appeal to you, you could use fish or seaweed emulsions or any of the other excellent natural fertilizers available at your local hydroponics supplier.

If you’re on a budget, fluorescents offer the biggest bang for your buck when getting light to you cannabis seedlings. Don’t forget to factor in the cost of electricity and bulb replacement. To make sure all my plants got an equal amount of light, I turned the trays 180 degrees every day. I especially liked the ease of raising the shop light one link at a time as the plants grew. You can maximize your light by using a room with white walls or surrounding your grow table with movable reflecting foil-covered cardboard or hanging sheets of Mylar—mirrors don’t work well for reflecting light.

Entering the Vegetative Stage

Toward the end of the vegetative and budding phase, you’ll be able to sex your plants. Males have two pollen-filled sacs that are easy to see and females have a pair of white V-shaped hairs. One male plant is enough to pollinate all your females so they produce seeds. I didn’t grow for seeds, so I quickly yanked all the male plants. Male plants are low in THC, are harsh-tasting and give many people a massive headache. Unpollinated females produce more flowers, buds and THC.

Indica-dominant hybrids are good for growing indoors, because they only get 2 to 3 feet tall from the top of the pot, with a diameter of 12 to 18 inches.

A: It is a daily, daily beast to take care of these plants. If you don’t acknowledge something it’s asking for for a day or two, you can lose two weeks of growth. Even if you do not mess up, that doesn’t mean you’re going to grow good marijuana.

Logistics and costs

Processing the harvest

A: Be discreet. You wouldn’t tell everybody you have $2,000 just sitting on your nightstand, so don’t tell everyone you have $500 to $1,000 worth of marijuana in your basement. Putting a lock on your growing-room door and installing a home security system is not a bad idea.

Growing cannabis from seed is possible but impractical.

A: When a plant is fully mature, some people cut it off at the base, then cut off the fan leaves and hang it upside down. After it’s dried, they’ll trim off all the outer “sugar” leaves (the single leaves close to the bud).
