the general rule of thumb is 25-50 watts of light per square foot, you have 100 sf, so you need 2500-5000 watts of light. Check out the led forums here, they seem to be the way to go, especially if heat is an issue.Keeping this in consideration, how many plants can you fit in a 10x10 grow tent?

About to grow in a 10x10 room. Would 2x1000W LED Grow light be good for 30-40 plants or 3 lights?

Secondly, how much area does a 1000 watt grow light cover? 7x7 feet

In this way, how many watts do I need for 10 plants?

Recommended wattage assuming 1.0 sq ft/plant

How much light do I need for my grow room?

By Wattage To grow a plant with a high light requirement,you want 30 to 70 watts per square foot of canopy. I would go for a minimum of 50 watts per square foot. If budget and heat is not an issue, bump that up to 65 watts per square foot.

MedicGrow Ez-8 1000W LED Grow Light for Indoor Plants

EZ-8 represents powerful LED grow lights for indoor plants we've ever made. It puts out more light than many other LED grow lights as well as 1000 watt HPS lighting solution. The wattage can be programmed up to 1000 watt to suit specific requirements.
This LED grow light puts out a full spectrum suitable for all phases of growth. It is designed especially for grow tents and several lights in a commercial operation. Covering 5x5 for both veg and bloom, it has been one of our most productivity-enhancing LED grow lights.
We design and build the LED fixture with one thing in mind: long-term usage. Therefore, Ez-8 is equipped with heavy-duty aluminum which can be worked in harsh commercial growing conditions with a lifespan up to 50,000 hours.
Furthermore, its 8 removable and replaceable bars make it easy to install and transport, and the integrated knob dimmer allows you to easily reduce the power output if you’re growing seedlings, or increase the power when blooming.
As a grower, we all know that light spectrum has a huge impact on efficiency of photosynthesis. Since 430 nm and 660 nm are both the strongest driving force for the photosynthesis of your medical plant, we created V1 spectrum which has a balanced wavelength covering all the phases of your growing.
