Starting your own indoor grow can seem complicated. 

You need a grow tent, lighting, ventilation, and much more. If you’re new to the world of hydroponics, it can seem like a bit of a minefield. 

This guide will tell you exactly what you need to start your own indoor grow. This is the complete hydroponic grow tent kit guide. 

Grow tent

The grow tent is the first thing you need to consider. This will house all of your equipment and create a separate environment for your plants to grow. The biggest limiting factor is normally space, so you need to pick a grow tent that can fit. We’d recommend measuring your space before you choose a tent. Also factor in some extra room for ventilation (more on that later). It’s important to consider the height of the plants that you’re growing - a grow tent with enough vertical height is essential if you want them to reach their potential.

Our recommended product is the Trojan Gold Tent TG24 2.4m x 2.4m x 2m.

Grow lights

Your grow light is the energy source for your plants. It provides them with energy, which allows them to process the nutrients you’re giving them. This is probably the most important (and sometimes expensive) piece of equipment you’ll buy, so make sure you choose the right one.

When choosing a grow light, you can’t just go for the most powerful. Too much light will put a strain on your ventilation system and could end up burning the plants. Too little light and your plants won’t grow properly. 

Here’s a rule-of-thumb for choosing a grow light:  You need between 45 and 70-watts per square feet of tent space. So, in a 3’ x 3’ tent, the square footage is 9-feet. That means you need between 405 and 630-watts. 

Our recommended product is the Gavita Pro 1700e LED.

Fans and filters and environment 

Grow tent ventilation is the next consideration for your setup. With the heat produced by the lights and the smell produced by the plants, ventilation is extremely important. Your ventilation requirements are determined by the size of the grow tent and the heat that the lights are producing. Without proper ventilation, your plants will die and your house will stink. 

Here’s a rule-of-thumb for choosing a ventilation system: The air in your grow tent needs to be refreshed around 20 times per hour, to avoid mould and excess heat and humidity. You can use a CFM calculator to work out the exact amount of power you will need from your ventilation system. 

Intake & Extract Fans 

Intake & extract fans recycle the air in your grow tent. The power is measured in CFM (cubic feet per minute), which is also referred to as airflow. To put it simply, CFM is how much air a fan moves. Some growers install the intake & extract fan inside the grow tent but you can also mount it on the wall outside the grow tent. 

Our recommended product is the Revolution Vector 315 EC.


Ducting is used to connect the ventilation system. It connects the grow tent to the air outside, through the intake & extract fan. The duct is secured to the intake & extract fan using clamps (provided with the duct). It’s important that the air is exhausted outside of the room because, as air is being sucked out of the grow tent, fresh air is coming into the grow tent. 

Our recommended product is the PhonicTrap Ducting 3m 254mm. Ducting

Carbon filter 

The carbon filter cleans the air, which removes the smell from the air being exhausted. This piece of equipment isn’t necessary but it’s often used by hydroponic growers that want to hide the smell. 

Our recommended product is the Pre Filter 100-315-1000.


A thermo-hygrometer is an essential tool in a grow tent. It displays the temperature and humidity levels inside the tent, so you can keep track of the conditions. Without one of these tools, you are growing by guesswork, which will result in a low yield. 

Our recommended product is the Grow Gadgets Digital Hygrometer.

Grow room timer 

The grow-room timer is one of the most important tools in the grow tent kit. It’s a fully customisable controller that can connect to all of the moving parts in your grow tent. You can program it to control your heaters, AC units, fans, humidifiers, dehumidifiers, CO2 regulators, lighting, and more. You can also connect it up to the internet for real-time data monitoring and to view historical climate data. 

Our recommended product is the Hydro-X Environment Control System.


You can’t grow hydroponics without nutrients. Because you’re not growing in soil, the plants have nowhere else to get their nutrients from. That’s why you need to pick the right nutrients and if you don’t feed them regularly enough, they will die. Check out the ChemGem range for some of the best nutrients in the business. 

Our recommended product is the ChemGen - Part A&B - Base Nutrient.
