Cannabis is a robust and durable plant species with an extraordinary ability to grow and adapt almost anywhere, from the cold and harsh terrains of Russia all the way to the tropical and humid environments on the equator.

Some cultivators have the luxury of massive indoor warehouses to grow entire crops of towering sativas, and others have acres of fertile land from which to harvest their buds. Others aren’t so lucky—some of us only have a small apartment space to work with, often with no balcony or outdoor space at all. However, this doesn’t mean that you can’t grow weed.

HOW TO GROW WEED ON A WINDOWSILL: THE BASICS

It’s possible to grow healthy and productive cannabis plants on a windowsill. This environment allows plants a good amount of natural light, and although cramped and small, it’s still a perfectly feasible option for growers who have no other choice. Of course, growing weed on a windowsill isn’t an optimal setup, especially when it comes to discretion. If sunlight is reaching your plant through the window glass, it’s almost certain that people will be able to see it too. Windowsill growing is best conducted in regions where cannabis is legal in order to keep the risk low. But if it’s your only option and you think you can get away with it, then it’s definitely worth a shot.

Below is a list of tips on how to start your windowsill cannabis garden and achieve the best yields possible.

CHOOSE THE BEST SPOT FOR YOUR PLANTS TO GROW

If your place only has one windowsill, then you’re stuck for options here. But if you have a few to choose from, set your garden up on the windowsill that receives the most sun exposure in the day. An east or south-facing window is the best choice. You should avoid windowsills oriented to the west if possible as this will expose your plant to intense and dehydrating afternoon heat.

If you live surrounded by high-rise buildings that block out direct sunlight for most of the day, then you can consider using artificial lighting above the windowsill to fulfil your plant’s daily needs. Although, this will obviously attract even more outside attention.

SELECT THE RIGHT POT FOR THE JOB

We’re not talking about strains here, yet. You need to choose the right container that suits your windowsill well. Because windowsills are often narrow structures, you’ll need to choose a thin pot for it to fit fully into the space. However, your plant will still have enough room to spread its roots if the pot you choose is tall. Anything around 2 litres will be small enough to fit on most windowsills, yet big enough to ensure decent-sized plants.

Another important factor to consider when growing on a windowsill is hydration. Most windowsills are positioned above heaters and radiators, and spending some of the day in front of hot glass can take a toll on plants. This is where pot selection is very important. Pots with water reservoirs can be used to ensure your plant has access to all the water it needs.

USE NUTRITIOUS SOIL FOR GOOD YIELDS

Not all soil is equal. Ensure you use the best soil you can find for this growing operation. Using small pots means you can only use so much soil, so the more concentrated it is with nutrition, the better. Make sure the soil you purchase is rich and dark, yet airy—nothing muddy or containing clay. It should also contain all of the required macronutrients—nitrogen, phosphorus, and potassium—as well as micronutrients.

CHOOSE THE RIGHT STRAINS FOR THE JOB

Now that you have everything you need to begin growing weed on your windowsill, it’s time to choose the right strain for the process. Autoflowering varieties are key here. These strains grow to small heights and have a rapid grow cycle, meaning they won’t have to be exposed to snooping neighbours for long. Plus, autoflowering strains don’t require a change in the light cycle to begin flowering. And finally, they are known for their hardy genetics, and are easy even for beginners to cultivate. These three strains are ideal for windowsill growing.

EASY BUD

Easy Bud is, you guessed it, very easy to grow. This makes her a good candidate for windowsill cultivation as she’s able to handle potentially harsh environments. She is an indica-dominant variety composed of 55% indica genetics, 15% sativa genetics, and 30% ruderalis. She is the daughter of parent strains White Indica and a ruderalis variety, and offers tastes and scents of citrus and herbs. Her 12% THC level offers a mellow and relaxing high that is subtle but effective. Even as an indica, she can be smoked during the day to reduce stress.

Easy Bud will grow to easily manageable heights of between 50–60cm indoors on a windowsill, and is capable of producing between 275–325g/m² in ideal conditions. The yield from a windowsill grow will likely be significantly smaller. Still, you won’t be waiting long until harvest; this lady explodes from seed to harvest in as little as 8 weeks.
