Your grow space must have adequate ventilation. The most severe issues with cannabis plants and their leaves are brought on by inadequate air circulation.
Concentrations of carbon dioxide, as well as other environmental factors, such as temperature and humidity. Grow conditions for cannabis plants are extremely limited. And that’s why it’s important to have proper ventilation and exhaust in your grow tent.
Why Your Grow Tent Ventilation Is so Important?
Your goal when setting up your grow tent should be to create an environment as close to natural grow space as possible. Furthermore, the more command you have over said circumstances, the better.
Everything revolves around the ventilation and exhaust system. It aids in keeping you grow tent’s air in a quality that promotes robust plant growth and abundant harvests.
Keep the Perfect Co2 Level for Cannabis
Cannabis, like other plants, needs carbon dioxide to grow. However, without enough ventilation, the CO2 in the air around plants in a closed environment will be quickly depleted and replaced by oxygen.
Therefore, we must find a way to restore it. There needs to be two-way airflow in your system for the fresh, CO2-rich air to enter and the stale air to exit.
Control Humidity and Excess Heat
Plants of The Cannabis Genus Do Best in Conditions that Are Just Slightly Over Human Body Temperature. for The Vegetative Stage, that Means a Temperature of 70–85 Degrees Fahrenheit (or 20–30 Degrees Celsius). Lowering the Temperature to Roughly 65-80°f (18-26°c) when Your Plants Are Ready to Flower Can Result in Higher Yields and Higher Quality Buds.
Humidity Management in Your Grow Tent Is Just as Important as Temperature Management. Water Is Released Into the Air by Plant Transpiration in Addition to The Natural Humidity.
Mold and Fungi Can Quickly Spread in A Moist Grow Room if You Don’t Have an Adequate Exhaust System. the White Powdery Mildew and Bud Rot Are Two Things You Absolutely Want to Avoid.
Avoids Pests and Plant Diseases in Your Tent?
The Dangers of Mold and Fungi Are Merely Some of The Organisms that Farmers Must Watch For. Insect Pests, Which Flourish in Warm, Humid Environments, Are Another Threat You’ll Need to Keep Away from Your Plants.
Well-Ventilated Rooms Make It Tough for Spider Mites and Fungus Gnats to Fly. that Is, if You Have a Properly Functioning Fan and Exhaust System, Your Plants Will Be Considerably More Protected from Them.
Ways to Setup a Ventilation System in Your Grow Area
An Appropriate Ventilation System May Necessitate Investment and Trial & Error to Achieve Optimal Performance. Even So, It’s a Worthwhile Part of Your Overall Plan. To Begin, You Can Either Use Passive or Active Intake to Set up Your Ventilation. Capable of Taking in Air Passively, an Exhaust Fan
When Negative Pressure Is Used to Achieve Passive Intake, the Airflow Is Said to Be “passive.” To Put It More Succinctly, You Have a Fan that Is Pushing Air out Of Your Tent, but No Fan that Is Pulling Air In. Rather, You Make Advantage of A Hole in The Tent’s Side that Passively Lets in Fresh Air.
It Will Often Be Three or Four Times as Large as The Exhaust Hole, or There May Be Several Smaller Holes for Passive Intake.
The Tent’s Pressure Gradient Will Keep the Air Circulating by Creating a Negative Pressure Inside. Most Farmers Will Find the Most Success with This Technique, Which Also Helps Reduce Energy Consumption.
Active Air Intake and Exhaust System?
However, You May Use a Fan to Actively Draw Air Into Your Grow Tent with An Active Intake System. So It Seems Like We Have a Team of Two Fans Here. You’ll Need Two of These, One to Prevent Air from Outside the Tent from Blowing In, and Another to Trap Air Within.
In This Setup, It’s Not as Crucial that The Intake Hole Be a Specific Diameter. So, if Your Grow Tent’s Intake Hole Is Roughly the Same Size as Your Exhaust Hole, You Can Set up A Rather Efficient Intake System.
With the Ability to Adjust the Speed of Most Fans, You Can Maintain a Comfortable Environment in Your Tent Regardless of The Weather Outside. However, You May Use a Fan to Actively Draw Air Into Your Grow Tent with An Active Intake System.
The Ultimate Ventilation Setup
The Basic Principle of Exhaust Systems Remains Unchanged. It Must Maintain a Constant Inflow of Fresh Air and A Constant Outflow of Stale, Stale Air, and Humidity.
However, Your System Can Be Improved by Adding a Wide Variety of Optional Accessories and Gadgets. in addition to Maintaining a Healthy Harvest, the Ideal Ventilation System Will Be Unobtrusive, Producing Little to No Odor or Sound.
I’m Assuming the Following Parts of Your Setup:
- Rope ratchets to hang your equipment.
- An exhaust fan (we’re going to be using a passive intake).
- A carbon filter.
- Ducting and clamps.
- A silencer.
- An oscillating fan.
- Air-cooled grow lights (most types of lights, such as LED, create almost no heat so don’t need to be included in your ventilation setup).
Ducting Your Fans and Accessories?
In the Next Several Steps, You’ll Hook up The Remainder of Your Gear to The Exhaust Fan. We’ll Use Aluminum Ducting for This Purpose. Flexi-Aluminum Ducting Is My Go-To Since It Meets All My Needs in Terms of Price, Adaptability, and Simplicity of Setup. However, Insulated Aluminum Will Also Perform Admirably if You Require Ducting for A More Robust System and Can Afford It.
Get Rid of Any Rough Spots so That Everything Runs Smoothly. And until You’re out In the Open Air, Choose the Shortest, Straightest Route Feasible. Longer and More Winding Routes Are Inefficient Because of The Extra Time and Effort They Need.
Because of This, It’s Clear that Proper Ventilation Is Crucial to The Well-Being and Output of Your Plants. if You Let Airflow Happen Haphazardly, Your Crop Won’t Thrive.
For the Best Harvests, You May Regulate the Airflow in Your Grow Tent in A Variety of Ways. One of These Should Be Just Right for You, but I Really Hope That you did. Keep this information handy and refer back to it whenever questions arise.
