how to grow cannabis step by step

Growing weed indoors is great because you can grow it any time of year and you’ll have complete control over the plant and what you put into it. Live in an apartment or a small house? Don’t worry, you can grow weed practically anywhere, even if you don’t have a backyard or a lot of extra space.

When starting with clones or seedlings, you’ll want to check your plants every day because they’re delicate and sensitive to environmental conditions. You may need to adjust temperature and humidity levels in your indoor grow space at first to hit the sweet spot for your plants.

What type of container you use will depend on the grow medium, the system, and the size of your plants.

Unless you know someone who has experience growing with a particular model of LED light, you’ll often spend a grow or two trying to get your light model “dialed in” so you know how far away to keep the lights from your plants for best results.

The “hardness” of water describes how much extra “stuff” (like minerals and/or impurities) is contained in your regular tap water. You can contact your local water supplier for more information (ask for a “municipal water report”), or you can test the PPM of your water at home. Generally, as long as your water has less than 200-300 PPM (parts per millions) of extra stuff, it should be okay to use it for growing. If you are worried about the quality of your tap water, you can choose to use purified or Reverse Osmosis (RO) water, but you may then need to add extra Cal-Mag and possibly a few other supplements to help make up for the random minerals and nutrients that are normally found in tap water. I’ve personally always grown with straight tap water (in a big city in California with a natural PPM around 370, which is pretty high), and I’ve never had a problem. However, some places have very hard water or tap water with unacceptable impurities, and growers in these areas will likely need to use purified water to get the best results.

Only feed nutrients at full strength if the plant is showing signs that it needs more nutrients (lower leaves are turning lime green, then yellow, then falling off – the first sign of a nitrogen deficiency, the most common type of deficiency – if the plant is not getting enough nutrients).

Step 9: Harvest Your Weed

How to grow cannabis step by step

Cannabis plants can be either male or female. Female plants yield the plump flowers, a.k.a., “buds,” that we know and love, brimming with psychoactive compounds like tetrahydrocannabinol (THC, which gets you high), Modern Farmer explains. Male plants yield much smaller flowers, which people typically don’t consume. In other words, if you want to actually indulge in your crop, you’ll want female plants.

Johnson notes that the outdoor grow season lasts from around April to October, meaning if you plant seeds now, they’d still yield flower, but not much. Since it’s late in the season, he suggests buying a large clone, which will have more branches and therefore yield more flower.

Before you get started

To check if your cannabis is ready for trimming, perform a break test on each branch. If it bends so much it nearly breaks, then it’s ready, and if it breaks right away, it might be overly dry, but still totally usable. Trim off the buds and seal them inside a mason jar for curing, opening it periodically over the course of about four weeks to let moisture escape. Johnson outlines a detailed schedule on his website, including instructions on how to look for mold.

Planting

There are different harvesting methods, but Johnson cuts the whole plant at the base and hangs it upside down with some twine in a dark room at a temperature of around 70 degrees Fahrenheit. Add a fan for airflow — you definitely don’t want the room to be humid, which will cause mold to grow, rendering your crop unusable. It’ll probably take around a week to dry.
