Grow tent: 300 x 150CM

The optimal tent for your indoor growth will always be context-dependent on your lights and space. Ideally, you want to get as much space as you can within the purview of your light. A grow tent is a portable, reusable grow room made of a sturdy canvas exterior and will usually have reflective interior material to increase the effectiveness of its built-in grow lights.

It offers insulation to retain the heat that the grow lights produce while stimulating plant growth. A grow tent allows you to recreate nature under your very own conditions. Grow tents are available in different shapes and sizes to accommodate different needs. 

Smaller grow tents are available for horticulturists looking to grow just a few plants, while larger ones are for those growing a full garden throughout the year.

Grow Light: Ceramic Metal Halide Lighting Kits

Your grow light is the most important part of your growth. In nature, the sun grows your plants. Grow lights are responsible for simulating the sun, both in terms of spectrum and intensity. After you have chosen a grow tent, you will need to choose your lighting technology. Which one of the lights is best for you depends on your goals as a grower. A lot of it comes down to budget as well.

CMH grow lights are made with an arc tube constructed of a ceramic composite instead of quartz or PCA. This allows the tube to reach a higher temperature. The higher operating temperature of the ceramic tube allows for an ideal mixture of gases.

 This creates a full spectrum of light that increases the growth, overall health, and yield of your plants. Ceramic Metal Halide grow lights, including Ceramic Discharge Metal halide and Light Emitting Ceramic (LEC) grow lights are becoming popular amongst commercial cultivators and hobby growers because they use up to 30% less energy and provide the same PAR/watt or PFF performance as traditional MH & HPS grow Lights while also producing less heat which requires less grow room air conditioning.

CMH lamps require a low frequency, which makes high-frequency digital ballasts incompatible. Whether you are brand new to indoor gardening or you are a veteran grower, a CMH grows light kit will remove the stress and hassle of finding the best ballast, light bulb, and reflector.


Ventilation can consist of a carbon filter, ducting, and an inline fan. These will help you manage heat and humidity in the grow tent, while simultaneously controlling odours. If you want to take things a step further, you can add an intake system. This will help bring in the fresh air and more importantly, CO2, when you expel old air.

You also need at least one clip-on fan to help circulate air and “make your plants dance”. Depending on the size of your tent, you may want a couple of these. Keeping the air circulating in your tent will strengthen stems, keep temps and odours lower, and help discourage pest and disease development.
