How To Grow Marijuana in 6 Steps. Quick Guide

How To Grow Marijuana Quick Guide
January 08, 2020

So, you want to know how to grow marijuana? Good choice! This marijuana growing guide will cover the basics, from how to germinate weed seeds to curing your cannabis. There are some shortcuts a beginner may be tempted with, like growing marijuana from a clone. For the best results, however, you need to learn how to grow cannabis from seed, how to germinate weed seeds, how to feed, water and nourish your plants, and how to harvest your weed properly. Everything a beginner needs to know about growing cannabis.

Step 1. Setting Up: Marijuana Grow Kit

The first thing we need to think about is buying your stuff and building your grow. How much space do you have? Are you concerned with odor? Do you have a big or a small budget? If you are just starting out, then start small. Growing cannabis can be expensive but a smaller grow will keep costs to a minimum. It’s easier to keep an eye on a handful of plants and, with a small-scale grow, any rookie mistakes won’t turn into huge financial disasters.

Make sure you have considered the final size of the plants, the extra equipment you’ll need (fans, lights, humidifiers, etc), and finally, you. Leave yourself enough room to work without being too cramped. Tight workspaces aren’t enjoyable and can lead to injuries to both yourself and your plants. Also important: the easier it is to clean, the better.


Next, pick your growing marijuana medium. There are a few options, hydro, coco etc, but for beginners, soil is often the easiest choice. You can buy inert or amended (super) soil, with the latter taking a lot of the work out of feeding. You can sit this soil in pretty much any container you want. Just make sure it has good drainage: a water-logged root system is NOT good for your plants. Smart pots are a good option, but again, this depends on your budget.


When cycling from light to dark, it is vital that dark STAYS dark. Light leaks can be disastrous for the plants, causing them to hermaphrodite. If you want to know how to grow cannabis properly, you’ll need help choosing your cannabis grow lights.

If you have the money, go for a top-end LED. There are products available that can go from veg to flower mode with the flick of a switch, but they’re not cheap. Growers normally use florescent (T5) lights for the early stages of the grow, moving onto Metal Halides (MH) for veg and High Pressure Sodiums (HPS) for flower. Your lights, especially the MH and HPS, will produce a lot of heat so make sure your space can be cooled and make sure it’s safe.

Temperature and environment

Along with lights you’ll need to control the temperature and humidity. Try to choose a space that’s already well-ventilated, with manageable temperature and humidity. Maintaining optimum conditions in your tent or room costs money, so choose your location wisely. This means fans, humidifier, dehumidifier, maybe even a full air-conditioning unit depending on where you set up. You might want to boost the C02 and you’ll definitely want a simple timer, if not a fully automated and responsive management system (if you can afford it).

Step 2. Start Growing

Once you have your equipment set up and your pots full of soil, it’s time to start growing. This video showsgerminating marijuana seeds can be simple. In fact, if you follow these steps, Homegrown Cannabis Co. will offer guaranteed germination, hugely reassuring for a beginner.

Choosing your seeds is easy with Homegrown’s search tool, and the mixpacks are a great way to match your needs to their seeds.

Step 3. Planting Your Seeds

Germinate Cannabis Seeds

Now you’re an expert at germinating your weed seeds, it’s time to start planting. This is quite an easy step, but you need to get it right. Red solo cups are ideal. Pierce a couple of holes in the bottom, fill them three quarters full with soil and moisten. Make a quarter inch hole using a pencil and carefully, using tweezers, lower the germinated seeds into the hole, taproot down. Cover with soil and top the solo cup with perforated cling wrap, using a rubber band to keep the wrap in place.

Once these grow into seedlings they can be transplanted into their final pots, although you might want to use an interim pot to help practice feeding and watering your plants. Cycling wet to dry is the best way to encourage a healthy root system. If you do decide to use an interim pot, you will need to look at transplanting your plants safely.

  • Tip! Transplant when the soil is relatively dry, a wet root ball will collapse under its own weight.

Step 4. Supercropping Your Plants

As your plant gains volume and spreads during the vegetative stage, those of you feeling confident may want to try supercropping your plants. Some of these techniques are trickier to master than others, but Homegrown’s resident genius, Kyle Kushman, can help get you going. 

Step 5. Flowering Stage

With good planning, you’ll know what size your vegging plants need to achieve before you start flipping your plants. This is the point at which you switch to a 12/12 light/dark cycle, giving your plant twelve hours of consecutive darkness followed by twelve hours of consecutive light.

Your vegging plants will now enter the flowering stage: white hairs will appear, forming buds and eventually colas. This last stage can be the most exciting: there is little in life more pleasing to the eye or nose than ripening your plants.

Step 6. Harvest Time!

The white hairs turn red as the flowering cycle nears completion, which means you should prepare to start harvesting your plants. You can use the same grow-space to hang your harvested plants, keeping them dark and aired. Most beginners opt to simply dry and store, but drying AND curing your cannabis means tastier, more smokable flower. It also means you’ll have mastered how to grow a marijuana plant. 

Congratulations and happy toking!
