Perfecting Your Growing Environment

5 Factors to Creating a Perfect Growing Environment
(from most important to least important)

In addition to making sure there’s air moving around in the grow space, it’s also important to vent out heat from your grow lights, especially if it’s getting too hot for your plants during lights-on. While many growers know they’ll need ventilation with powerful HPS lights, it’s important to note that ventilation can be just as crucial for LEDs, LECs and even fluorescent lights like CFLs or T5s if the total wattage gets high enough. For each light type, the higher the wattage, the more heat produced. If you notice the temperature is climbing above 85°F (30°C) on a regular basis, you should consider venting heat out of the grow area to keep the temperature under control. However, if the overall temperature of the entire grow room is too high, you may need to take more drastic actions such as getting an AC. Fans can move air around, but can’t lower the total amount of heat in a room.

2.) Temperature

What makes the perfect cannabis growing environment? What does it take to get the healthiest growth and best yields from your indoor cannabis plants?

Light also changes how your plant grows. For example, the color spectrum of light can cause your plants to grow tall and lanky or more bushy and squat. Some grow lights like LED grow lights take advantage of a custom color spectrum to help your plants grow as optimally as possible.

Unless it’s very high or low, humidity usually won’t cause any major problems with your cannabis grow. However, there are a few tricks with humidity to get faster growth and more resin production on your buds.

However, it’s also possible to give your cannabis plants too much light, especially with big grow lights, so it’s important to keep grow lights the right distance away.

Benefits of a great grow environment

These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.

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.

The growth stages of marijuana can be broken down into four primary stages from seed to harvest:

The main drawback is fluorescent lights are less efficient, generating about 20-30% less light per watt of electricity used; space is another concern, as it would require approximately 19 four-foot long T5 bulbs to equal the output of a single 600 watt HPS bulb.

You’ll need to ensure that temperatures remain within a comfortable range for your plants, between 70-85°F when lights are on and between 58-70°F when off. Some varieties of cannabis—generally indicas—prefer the colder side of the range, while others—typically sativas—are more tolerant of high temperatures.

For the most part, weed prefers these temps at each growth stage for optimal health:

Finding the right soil for cannabis

You can also use a timer for your fans, but a thermostat is better—you can set it to a specific temperature, and the fans will turn on when it’s too hot and turn off when it’s too cold.

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.
