How To Grow Cannabis In A Garden Shed

As you know, cannabis is big business these days. All it takes is one trip to the cannabis dispensary and you’ll be greeted with an amazing variety of marijuana strains as well as other various products such as vape oils, CBD lotions, and even THC gummy bears.

However, if you’re a real cannabis enthusiast, there is nothing better than growing your own herb and enjoying the fruits of your labor. You know, sometimes it’s not a bad thing to get high off your own supply. Although, whether you’re an experienced cannabis farmer or a total newbie, it’s important to remember that growing cannabis is a delicate art.

The cannabis plant has a particular set of needs you must account for if you want to yield a healthy and bountiful harvest, but if you get it right, there’s no denying it will be some of the best weed you have ever smoked!

With that said, here’s how you can grow cannabis in your garden shed by creating the perfect microclimate of water, nutrients, heat, humidity, and regulated lighting. Let’s get into it.

Benefits of growing cannabis in a garden shed

It’s a dedicated space separate from your living area

Using your garden shed as a grow room is ideal for those who don’t want their grow space to encroach on their living area. This means you can focus on creating the perfect conditions for your plants rather than having to compromise due to issues that arise from living in the same area, such as heating and humidity.

You can control the climate more easily

When growing cannabis outdoors, the success of your crop is at the mercy of the elements. If you have bad weather for a few months or low levels of sunlight, it will negatively impact your harvest quality. Growing inside a shed gets rid of this problem.

You can grow/harvest any time of the year

Once again, if you grow your cannabis outdoors, you are restricted to the seasons that provide adequate lighting and heat. Depending on where you live, this will most likely mean you won’t be able to ensure a year round harvest; however, this is entirely possible with a garden shed grow room.

Choose the right lighting

First things first, you need to make sure the shed is entirely light-poof. This means that no light should leak in or out of the room when all of the doors are closed. Why? Light leakage will confuse indoor plants and cause them stress, which will result in a reduced yield.

Next, you need to choose the right lighting system. There are three artificial light sources to choose from, these are:

  • HID
  • CFL
  • LED

Generally, the option you go for doesn’t really make a difference; it is only a matter of opinion and preference. Here, the important thing is to find a lighting solution that provides the right amount of heat, light, generates the correct wattage, and doesn’t cost you a fortune on energy bills.

400-600W per m² is plenty of light for a garden shed to grow. As for lighting schedules, aim for 18-24 hours of light a day during the vegetative state and 12 hours light and 12 hours dark each day during the flowering phase.

Pick your climate controls and monitors

Your cannabis plant will only thrive if the climate is controlled adequately. The humidity and temperature must be kept within specific parameters for your plants to maintain a happy and healthy life for plants that’s ideal for vegetation.

In order to control the humidity of your garden shed, you should use a dehumidifier. These machines allow you to add and subtract humidity where necessary. In general, a humid and warm environment increases the rate of growth. As for the temperature, you can install portable, reverse cycle AC units that allow you to easily control the temperature inside the shed.

Feed your cannabis plants nutrients

Marijuana plants require three nutrients in large volumes in order to be healthy. These are nitrogen, phosphorus, and potassium, so you must do what you can to ensure they receive adequate levels of each. Fortunately, you can buy ready-made fertilizer from the local marijuana dispensary containing all of the necessary nutrients and in the correct ratios.

As for the soil, you can usually pick up a ready-made bag of high-quality soil at your nearest garden center, but if you want to make your own, try and include high-quality compost, peat moss, and even things like worm castings and bone meal.

Water your cannabis plants

The tricky thing about watering your cannabis plants is that it isn’t an exact science. It requires experience and the ability to look at your plants to decipher whether or not they need watering.

More often than not, people end up overwatering their plants as they incorrectly assume they are wilting. As a rule of thumb, you only want to water your plants when the soil feels dry or if the leaves are starting to look a little bit yellow. A well-watered plant will feel strong and vibrant with healthy green leaves.

If your plants look a little dry, water your plants until the top layer of soil is moist. Wait ten minutes and allow for the water to drain through. If it’s bone dry again, it means the plant still needs more water. Repeat the process until the top 5cm of soil is lightly moist and keep on top of it by lightly spraying the plants every 1-2 days.
