A good grow set-up is essential for a good cannabis grow! Here we offer guidance for what you will need to set-up your grow depending on your space and goals. We provide our recommendations for the best grow tents, ventilation equipment and climate control accessories for your indoor cannabis grow.
Grow Tents & Spaces
Grow tents offer many advantages for home growers. They allow you to control the climate and light that your plants experience. They also provide a reflective interior to help maximize the efficient use of light. A grow tent can be set up in any room and can be packed up and put away again if needed.
We recommend two brands of grow tents above others. The Vivosun tents are great quality grow tents at really great prices. They feature 600D canvas, metal poles, and quality zippers. Users report good experiences with them and few light leaks. We recommend them for tents sized 3’ x 3’ and above (see below). We do not recommend the Vivosun 4’ x 2’ tent because it is too short.
The Mars Hydro tents are an upgrade over the Vivosun and most other grow tents on the market. They feature 1680D canvas, sturdy metal poles, and quality zippers. We recommend the Mars Hydro tent as our pick for the 4’ x 2’ grow tent below because it is taller than other similar tents. We recommend the Vivosun tents for the other sizes based on price and value. If you want to upgrade from the Vivosun tents, the Mars Hydro tents are a great option. The best deals on Mars-Hydro Grow Tents are through their website (use discount code: CCFC).

Create Your Own Grow Space
If you do not want to get a grow tent, then there are a few products that you can use to help modify your existing space to be reflective and sealed.
Aluminum Foil Tape
In a ventilated grow space, the exhaust system is one of the most critical components.
The exhaust system that you need will depend on the size of your grow space, the heat generated by your grow lights, and the climate that you are working with.
4" Exhaust Kit
6" Exhaust Kit
The starter kits above come with exhaust fans, however, there are several reasons to opt for an upgrade. The AC Infinity fans that we recommend below are more powerful, quieter, and are controlled by heat and humidity sensors. These fans work with you to help you manage the climate and keep the plants happy. They are an added investment, but if you are concerned about managing the climate in the grow space, they are well worth it.

6" Mixed Flow Fan
Carbon filters attach to the intake end of your exhaust system (inside the grow space). The exhaust fan pulls air through the filter (and then through the hood of HID lights), and then pushes it out of the grow space.
4" Carbon Filter
Mufflers: Noise Reducers
4" Turn-Key Duct Clamps
Semi Rigid Duct Hose
I use and recommend “Semi-Rigid Flexible ducting”. It has much better airflow than other flexible ducting, which improves the efficiency of your fans. It is easy to shape into any position and it holds its shape.
4" Semi Rigid Ducting
Using active intake is the best way to control the climate inside your grow space. If you use a good exhaust fan without an active intake fan, the exhaust fan will practically cause the tent to implode. In small grows with little heat or humidity to manage, you may be able to do without and use passive air intake.
The goal with active intake is to help balance air pressure, but you always want the exhaust fan to be more powerful than the intake. You want to avoid the cheaper inline fans that will not work against any resistance. You also want to avoid high powered fans that would eliminate the negative air pressure in the tent.

In order to control the climate, you first have to know what it is!

Inside the grow space it is important to keep the air moving around. You don't want too much wind, which can injure plants, but you need to keep the air moving to maintain optimal conditions for growth and to reduce the chances for pathogens. We recommend using two fans to move the air around in most grow spaces. Consider your budget and your grow space and you can choose among the following options.
Ozerri Brezza Dual Oscillating Fan
6" Clip Fan
I live in a very dry climate, which is perfect during most of the grow because the plants themselves produce a lot of humidity. However, early in the grow when the plants are small I must use a humidifier to create the ideal environment for seedlings and young plants. We recommend ultrasonic humidifiers as they do not use heat to create humidity, but Instead atomize water through ultrasonic vibrations. The absence of heat is important so that it does not interfere with the grow room's natural balance and create more problems than it tries to solve.
Large Ultrasonic Humidifier
Small Ultrasonic Humidifier
Most growers can control humidity by leaving the exhaust running. Dehumidifiers are needed only in sealed rooms, or climates with very high humidity. Dehumidifiers can be helpful for grow rooms where high humidity is a problem, however, a problem with dehumidifiers is that they create heat. We do not recommend simply exhausting the hot air because doing so also removes the dry air and defeats the purpose. In hot and humid areas, you may need to seal the grow space (limit air exchange through exhaust) and use a double vented air conditioner along side a dehumidifier.
Frigidaire 70-Pint Dehumidifier
Air conditioners are very useful when exhaust systems can no longer control heat. You can get AC units that are single or double vented. Single vented units are fine for most set-ups when you are not using a dehumidifier.
Single Vented Portable A/C
Double Vented Portable Air Conditioner
If it is too cold in your grow space, you may need to add a heater. We do not recommend using fan heaters, or any heating system that can create a fire risk if something were to happen. Oil heaters are the best option for heating as they distribute their heat safely without getting overly hot on the surface.
