LED Bulbs for Grow Lights
You can use any LED bulb to grow plants if they are emitting enough light. Plants often also look for warmth to come from the light source and we know LED bulbs do not provide much of that.
Consequently, what wattage is best for indoor grow lights?
First, determine how much space you need to illuminate. As a rule of thumb, aim for 20 to 40 watts per square foot.
