What Size Grow Tent for 2 Plants
What size grow tent do I need for 2 plants? A 2′ x 2′ Grow tent is the minimum size grow tent you’ll need to grow two plants using the Sea of green technique. A 2′ x 4′ grow tent, or a 4′ x 4′ grow tent would be a better choice if you plan on using the Screen of Green Technique.
Sea of Green: 2′ x 2′ Grow Tent
Screen of Green: 4′ x 4′ Grow Tent
Topping: 4′ x 2′ Grow Tent
Low-Stress Training: 2′ x 3′ Grow Tent
Sea of Green – 1 sq/ft per plant
The sea of green technique requires one square foot of space per plant. That means you’ll need a small grow tent with at least 2 sq/ft of space for two plants. You usually won’t find tents this small, so it’s a good idea to get a 2′ x 2′ Grow Tent if you plan on using the sea of green technique.

Low-Stress Training – 2 sq/ft per plant

Choosing the Right Size Grow Tent
Plants have different sizes and shapes depending on their genetics. The size of a plant’s stem, leaves, and its overall height will all be things you need to consider when you choose a grow tent.
Some plants will reach a greater mature height than other plants, which might require that you get a taller 72-inch grow tent instead of a more compact 63-inch grow tent.
Also, some plants can have a wider canopy that can crowd out neighboring plants, which can limit light penetration and air circulation.
To avoid this problem you’ll need to get a grow tent that is big enough to allow for enough space between each plant.
Type of Light
The type of light you use will also dictate how you size your grow tent. High-Pressure Sodium and Metal Halide lights will require a larger tent than LED Grow Lights.
This is primarily due to the fact that HPS and MH lights produce a lot of heat that can be hard to dissipate in a smaller space.
HID lights also need to be placed high above the plants to avoid the risk of damage due to the intense light and heat they emit. That means you’ll need to get a taller 72-inch tent if you plan on using a Metal Halide or a High-Pressure Sodium Lamp.
Hydroponics vs Soil
Plants grown in soil will need more space than plants grown in a hydroponic system. In most cases, a plant grown in soil will need 1.5x more space than a similar plant grown in an Ebb and Flow Hydroponic System or a Deep Water Culture System.
A larger grow tent will need a more powerful ventilation system to handle odors and exhaust excess heat. That means you’ll need to size your fan and carbon filter accordingly to match the size of your grow tent.
A smaller 2′ x 2′ grow tent for 2 plants will usually only need a 4-inch inline fan. However, if you get with a 4′ x 4′ grow tent you might need to upgrade to a 6-inch fan and carbon filter to handle the larger volume of air in the tent.
If you live in a small house or apartment then you’ll most likely have a limited amount of space for a grow tent. That means you’ll want to get the smallest grow tent possible, while still providing enough space to grow healthy robust plants.
A small 2′ x 2′ grow tent would be your best option if space is limited. You could use the sea of green technique in that case to maximize the yield you get from a small grow tent.
If you have more space then a 4′ x 4′ grow tent would be a better option since you can grow just a couple large plants, which can help you avoid all the extra effort it takes to maintain the sea of green technique.
This article has addressed some of the things you should consider when choosing the right size grow tent.
However, there are still lots of personal factors like your climate, electricity costs, living arrangements, and your stamina/health that you’ll need to factor into your final decision.
The key takeaway is that a grow tent needs to be properly sized to provide ideal growing conditions for your plants. When you get this right it will result in healthier plants that will provide a bountiful harvest for years to come.
