LED Grow Lights
Rather than using natural sunshine, grow tents rely on grow lights that emit the ideal range of light needed for maximum growth, plant health and yield. These are a little different from regular lights, and there’s a lot to consider when buying a grow light.
LED grow lights are the most compact, which is best for smaller tents that aren’t especially tall, and they use the least amount of energy, which saves you money in the long term.
They also give off the least amount of heat, so your plants aren’t at risk of burning and controlling the tent temperature is much easier.
Here is our top selection of cheap LED grow lights.

Proper Ventilation for Your Plant
All plants need good airflow in order to grow. Good ventilation gives plants access to carbon dioxide that they need for the photosynthesis process and oxygen for cellular respiration.
Air flow also helps to regulate temperature more effectively, and prevent excessive humidity that can cause rot and mold outbreaks.
The best grow setup for indoors we’ve recommended have vents for airflow, but it’s a good idea to add a fan to keep the air moving properly and mimic the breezes your plants would experience outdoors.
Here are our recommendations for the 3 best cheap grow tent fans.

Extra Upgrades for Your Grow Tent
Of course, the sky's the limit in terms of upgrading your grow tent and adding new features, and the best grow tent setups for indoors can become very complex and costly.
If you have some space in your budget to add a couple of upgrades, here’s what we’d recommend.
Heating or Temperature Control
Marijuana is a tropical plant and loves warmth, so a heating rig is a good idea if you are in a cold climate and using a space that doesn’t have good heating, like an unfinished basement, garage or garden shed.
Ideally, the temperature in the grow tent should stay at 85 degrees Fahrenheit.
