Frequently Asked Questions (FAQs)

How many plants can I grow with 1200W LED?

In reality, this can vary with the type of plant and other related factors. Going by the somewhat popularly adopted standard of 1 sq ft of grow space for one plant to 50 watts of LED grow light, 1200W should cater for 1-24 plants. However, if you want to ensure that all the plants develop as they ought to, you should use multiple lights that provide enough illumination for the entire canopy.

How far should a 1200 watt LED light be from plants?

A useful rule of thumb is that the more powerful the light, the farther away it should be from the plants. The optimal height for both veg and bloom will slightly vary across different lights, but it typically falls in between 24” – 46”.

How much power does a 1200 watt LED grow Light use?

That a grow light is rated at 1200 watt doesn’t mean it uses that much power or that it produces such level of power. The actual power that they use can be as low as 200 watts or as high as 700 watts. This is why LED grow lights are the best in terms of energy efficiency.


Following our rigorous process of research and tests, these are those that have made it to our best lists. In addition to functionality and durability, we have also considered energy efficiency in choosing them.
