Question 1

What is a 300 watt LED grow light equivalent to?

Accepted Answer

In actuality, this light is equivalent to 200 watts of HID power and uses somewhere around 130 watts.

Question 2

How many plants can I grow with a 300w LED light?

Accepted Answer

So a 300W can cover about 2 x 3ft area. In fact, each cannabis plant you grow requires at least 1sq ft of space. So under 300W, you can grow about 1-6 plants. When cannabis is grown, a decent rule of thumb is to use a minimum of 50 watts of light per square foot of the growing field.

Question 3

How far should my LED lights be from plants?

Accepted Answer

The general rule is that LED lights should be approximately 12-30 inches from the top of your plant. When your plants grow, you need to adjust your lights’ height to match the height of your growing plants. In short, the LED lights are the type of light used by gardeners. Since LED lights emit much less heat than other forms of lights, plants can withstand far closer LED lights. Usually, most people tend to adjust the height of their grow lights using basic chains or cables that allow the light fixture to be elevated or lowered, based on the plants’ height.

Question 4

What are true Watts?

Accepted Answer

A true watt is the calculation you want to know to assess your growing sun’s real energy consumption. The real electricity used by both the electrical circuits and the lamps themselves – fans, etc. – is referred to as true wattage. While true wattage is a good indicator of power generation, it is not a good measure of light intensity because you have no idea how effective the system is. PPFD is the only real and useful indicator of light output for growing lamps.

Question 5

Are Chinese LED grow lights any good?

Accepted Answer

If you carry Chinese LED lamps, you will feel how light they are, with dubious longevity. LED chips are mostly tiny and unstable relative to existing varieties. Many of the Chinese-made rising lights offer a lifetime of 50,000 hours but produce considerably less.
