What are the length x width dimensions? You've given one of 2foot 7 inches (80cm), but we need the other dimension to answer the question.

These LED panels meet minimum suggested wattage numbers per square foot, And will also give you less than optimal results in your size tent. You can also use two of any of these lights, and it brings you right up into the 40-50 watts per square foot range:
LED Grow Light 100x3w - Mars Hydro (21 watts per square foot)
Reflector LED Grow Light 96x3w - Mars Hydro (24 watts per square foot)
Mars II LED Grow Light 400W - Mars Hydro (24 watts per square foot)


These LED panels will give you better results:
LED Grow Light 200x3W - Mars Hydro (43 watts per square foot)
Reflector LED Grow Light 192x3W - Mars Hydro (50 watts per square foot)
Mars II series LED Grow Lights- Mars Hydro (43 watts per square foot)

And this one might work, but is a lot higher than normal watts per square foot that I see suggested:
Mars II series LED Grow Lights- Mars Hydro (58 watts per square foot)

Hello Fiete, as you are the first time use our lights, and due to your limited space, I would suggest you choose the mars II 400w first. and by the way, thank you@Antics.

Most of the answers you need can be found here: How to Grow Marijuana Everything You Need to Know

Specifically: How Much Ventilation Do I Need in My Grow Room?

Calculate cubic footage of your grow space, multiply the total times 3, as well as 5, and that gives you the range of the fan's CFM you need.
