While this is true to an extent, there is such a thing as “too much water.” Overwatering your indoor cannabis plants can prove detrimental to their productivity, and potentially stunt or kill them!

The first step is to cut off the big water leaves, otherwise known as the fan leaves. They have minimal THC in them and are generally removed. You’ll notice a visible difference between the long, green fan leaves and the smaller sugar leaves. The latter is covered in resinous glands (trichomes).

It’s very important to grow your cannabis plants to a size suitable to your space and likewise to the container you choose. You will need to transplant every time your plants double to triple their size. Small cups or 4-6” pots are good for starts.

Step 6: Choose a “Canna-tainer” (Container) to Grow Your Cannabis In

Make sure that you have enough space to work in!

The 24-hour timer is just as important. When the marijuana plants are in vegetative growth, you need the light supply on for around 16-24 hours per day. Once they mature and reach the flowering stage, your plants need 12 hours light and 12 hours dark.

Step 10: Cut Your Cannabis Plants Down — Carefully!

General potting soil doesn’t work very well. You want a high-grade horticultural potting mix, which is light and airy. Some mixes come “charged” with a small amount of nutrients to get you through the first few weeks. However, these will need regular fertilizing later.

By “small,” I mean nothing more than a few plants at most. You can start with just one or two plants. There’s an inevitable learning curve involved with growing weed indoors and you’re bound to make some mistakes.

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.

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.

If you’re growing in a cold, wet basement, you might have to run a dehumidifier or heater to stabilize the environment. Conversely, if your space is too hot, you might need to add extra fans or an AC to cool the plants down.

Watering is something that many new plant parents struggle with. Are you giving too much? Too little? Should it be reverse osmosis or filtered? For new cannabis growers, it’s best to start off simple.

Soil and hydroponics are two of several options available when it comes to cultivation mediums, another that’s popular with home growers is called coco coir. “It can be very fun to try something new like coco coir. This grow medium gives you more control over nutrients and can significantly improve the yield and quality,” explained Samuel Belanger of GrowBuds.

For the majority of home growers, using tap water should be just fine. But in order to be sure, it’s best to have a detailed picture of what’s in your water.


While it’s totally possible to grow a cannabis plant in your living room without supplemental lighting, adding even just one grow light can give you a lot of bang for your buck when it comes to outcome and yield.

If you’re using a hydroponic growing system, you’ll need liquid nutrients and growers often turn to synthetic formulations. Liquid nutrient systems can be fairly simple, with one catch-all formulation for vegetative growth and another for flowering. Or they can be quite complex, breaking down individual components so growers can concoct their own magic potions for specific cannabis strains, environments, and stages of growth. Add synthetic liquid fertilizers and nutrient solutions to water for use on plants growing in soil.

Seedlings and maturing plants in the vegetative stage of growth need lots of light. These plants should get at least 12 and ideally 18 hours of direct light per day, which means if you’re growing a photoperiod plant and relying on sunshine alone, you need to time the growing cycle to maximize the increasingly long daylight hours of spring and summer.

Just like you, plants like to be comfortable. What does comfortable mean for a cannabis plant? Generally speaking, the environment inside your house will be comfortable enough, though there are a few things to keep in mind.
