Growing weed in the dark

A: Place the clone in a pot filled with a planting medium. Although potting soil would technically work, we use a soilless growing media made from coco fiber, worm casings, perlite and vermiculite because it’s developed specially for marijuana, even though (manufacturers) don’t admit that. You can get premixed versions at grow stores — Royal Gold Tupur is a good brand.

A: Most nutrient products in hydroponic stores come with very easy-to-understand directions and a “recipe” and schedule on the side of the package that you can follow. You should also water the plants every two to three days with tap water that has sat in a container for 24 hours to let the chlorine evaporate.

If you’re 21 or older, Amendment 64 allows you to cultivate up to six marijuana plants in an “enclosed, locked space” in Colorado. (This is still illegal under federal law.)

A: Hemp is basically a cultivated variety of sativa. For several thousand years, it has been bred for tall growth, fibrous stems and low THC levels. It still has the medicinal cannabinoids, but you need so many hemp plants to get valuable cannabinoid content — more than 100 — that it wouldn’t be worth growing at home.

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.

These are unprecedented times and we are committed to protecting both our employees and our communities. Clean air has never been more important, and we’re making sure our customers have everything they need. From those working from home who need high quality air filters, to the other essential businesses we supply products to, we’re here for you.

Cannabis Growth Timeline

The quality of your plant depends on your knowledge of the cannabis growth stages and the lifecycle of your plants.

Our phone lines are open from 9am-5pm central time, Monday through Friday. Our staff is working remotely wherever possible and we will maintain a bare minimum staff on-site to perform basic operations of order processing and accounting. Our on-site staff will follow the appropriate best practices and guidelines set forth by OSHA’s latest release of "Guidance on Preparing Workplaces for COVID-19."

Covid-19 Plan

Male: Small green sacs full of pollen will be seen on the node areas.

1. Germinating: 1-7 days
2. Seedling: 2-3 weeks
3. Vegetative: 2-8 weeks
4. Pre-Flowering: 1-2 weeks
5. Flowering: 6-8 weeks
6. Harvesting

Female: Two pistils (the pistil contains the reproductive parts of a flower) will be growing on the buds (flowers grow above these leaves, one cluster on each side).

3. Vegetative Growth

How to tell if your plant is a male or female

It can take anywhere from 4 to 8 months to grow a cannabis plant, this varies based on where you’re growing. If you have an indoor grow room, your plant has the ability to flower after only a few weeks!

Covering and uncovering your greenhouse on a set schedule, day in and day out can be extremely time and labor intensive. Pulling tarps is a lot of work, but using the right tools and products makes all the difference. To improve your harvest, you need to provide ample, reliable darkness for your cannabis, a good light deprivation cover and a tarp puller system will help you maintain your light deprivation schedule.

What many growers don’t realize is that cannabis demands an uninterrupted dark cycle. Just as your good REM sleep would be interrupted if a light popped on at 2 a.m., cannabis doesn’t fare well when any light disturbs it during its dark “sleep” cycle. The moon and stars don’t bother cannabis, but any artificial light can stop its bud growth. In fact, light interrupting its dark cycles can make cannabis so stressed and irritable that it can lead to hermaphroditism. That can pollinate females and ruin your plants.

If you decide on the classic 12/12 light dep schedule where you cover your plants at 7 p.m. and uncover them at 7 a.m., be consistent with that schedule. Keep in mind that this schedule requires adequate ventilation, so some growers will choose to uncover their plants at night once the sky is completely dark.

Cannabis is a photoperiodic plant that responds to seasonal changes in light. That means when the days grow shorter, the plant’s life cycle is nearing its end, and flowering occurs for reproduction. In nature, male cannabis sacs release pollen to pollinate female plants in blossom. The result is seeds, which allow the plant to produce the next generation.

Keep to Your Chosen Schedule

Cannabis in the vegetative stage (when it is growing at a rapid pace) needs at least 13 hours of light per day. In fact, indoor growers commonly use an 18/6 light to dark ratio to encourage faster growth. (Note that most indoor growers vegetate their plants 4 – 8 weeks.)

As a cultivated plant, cannabis still responds to light changes. Depending upon the strain you’re working with as well as your environmental demands, your light-to-dark ratio will vary a bit. If you’re new to the strain (or growing), talk to old hands about when to end the vegetative phase and trigger your plants’ flowering phase. That timing is critical to maximizing your yield. Here are some more specifics.

When you are ready for your cannabis plants to flower, a 12-hours of light and 12-hours of darkness schedule is standard. Nighttime provides darkness, keeping cannabis on somewhat of a natural clock. This is why indoor growers need to make a deliberate effort to not only create long, bright days but also emulate dark cycles for cannabis to grow large full buds.

The Flowering Stage of Cannabis

Cannabis growers know darkness is as important as light. You may not think of the principles of yin (dark) and yang (light) when planning your light deprivation schedule, but savvy growers understand the dual needs of cannabis. And whether your greenhouse sits in the Pacific Northwest under long summer days or in the hotter climes of the Central Valley, it’s essential to balance darkness and light for a maximum bud harvest.

Americover’s BOLD® Black Out Light Deprivation Tarp is the top-selling greenhouse cover of its kind nationwide, consisting of two sheets of high strength virgin polyethylene film laminated together with a third layer of molten polyethylene. The cover is scrim reinforced for superior tear resistance. Plus, the cover can be easily set or lifted with the BOLD EZarm Tarp Puller. The BOLD EZarm allows one person to easily cover and uncover a greenhouse without additional help, making the daily chore of light deprivation so much easier.
