No one mentioned there'd be any math—right? No worries, we'll help you out here!  Begin by figuring out the square footage of your grow. For example, if you're planning a four-plant grow in a 4x4, that's 16 square feet.

A simple way to estimate the recommended amount of lighting is to follow

• 25 watts of light per square foot

THEREFORE in a 4x4, you'll want to have around 400 watts of light while flowering.

Pro Tip: Seriously consider investing in a grow tent. It not only brings much-needed consistency to your grow but also leads to larger and more abundant plants—meaning more bud for you. It's like setting the stage for your plants to become rockstars. The reflective material keeps the light in and maximizes light efficiency.
