growing cannabis indoors during winter

Before watering, check the pH of your water and add pH Up or Down if needed.

For most first-time gardeners, we recommend buying a quality potting soil that will provide your plants with enough nutrients to get them through most of their growth cycle without having to add many amendments or liquid nutrients. This pre-fertilized soil—often referred to as “super-soil”—that can grow cannabis plants from start to finish without any added nutrients if used correctly.

There should be a comfortable airflow both above and below the canopy, and fans shouldn’t blow air directly onto plants—this can cause wind burn, which makes leaves recede into a claw-like deformation.

Caring for your indoor cannabis plants

Examine the tops and undersides of leaves for pests or discoloration—spider mites live on the underside of leaves—as well as stalks and branches. Also, check the soil for pests.

Every space is different and there will be a learning curve to growing in yours.

Inevitably, there will be fluctuations of temperature and humidity in your cannabis garden. These fluctuations can occur both throughout a grow space as well as within pockets inside a given room. They can also occur at different points within a given day or throughout a season as conditions change in the environment outside your grow space.

Finding the right soil for cannabis

Inexpensive options include standard plastic pots or cloth bags, while some growers choose to spend more on “smart pots” or “air pots”—containers designed to enhance airflow to the plant’s root zone.

That’s a big variance, but it really depends on how big you want your plants and how often you want to harvest—you can have multiple harvests of smaller plants, or less harvests of bigger plants.

At the same time, we strive to produce interesting articles which people will find entertaining and relevant. We also host the Sensi Seeds forum, but we are not responsible for its content as it is all user-generated.

It is true that growing in the winter takes a little more attention and a little more TLC. With the right advice and the right frame of mind, you can successfully grow all year round. That is what we are here to help you do!

Thanks for your kind words! I do wish we could simply give grow advice in the comments section, but unfortunately that’s not a service we can offer right now. Also the forum is no longer active, although it is still there to be used as an archive, so I’ve had to modify my replies. Now I say that other readers will often offer advice if they can, so the comments section can serve the same basic purpose as the forum. I hope you continue to enjoy the blog,


If you are an old-school cannabis grower, then you probably love growing in the winter. That is because last decade’s HID (high-intensity discharge lightning) technology emits alot of heat. And if you are using them in the summer time, then you need to pay through the roof for air conditioning. But in winter, HID lights can keep your grow room at the optimal temperature.
