How many watts should a grow light be?
As a rule of thumb, aim for 20 to 40 watts per square foot. Divide the wattage of your bulb by 20 (such as 400 watts divided by 20 = 20), and then divide the wattage of your bulb by 40 (400 divided by 40 = 10).
Does wattage matter for grow lights?
The simple answer is: it’s not really about wattage. Wattage is a measurement of electricity consumption, and while it’s helpful to know how much wattage your grow light uses (so you can make a more economical, energy-saving choice) it actually has nothing to do with the amount of energy your plants need to grow.
Will any LED light work as a grow light?
Regular LED lights can’t be used as grow lights, even though they may emit some of the wavelengths necessary for plants. Regular LED lights don’t emit enough of the light that plants require. Plant growth primarily requires red & blue light, which LED grow lights are designed to maximize.

What size light for 4×4 grow tent?
For a 4×4 tent, you should have a grow light having an actual wattage range of 500-600 watts (assuming flowering plants which require a lot of light and are congregated in a single area. Vegetative growth for high-light plants need about half this wattage).
How many watts do you need for veg?
Veg Room Set Up A good rule of thumb is that between 10-20% of your total light wattage in the Flower Room will be used in vegetative growth. This means that if there are 50,000 watts in the Flower Room, there should be between 5,000 and 10,000 watts in the Veg Room.
Can I have too much light in my Grow Tent?
