How close can LED lights be to plants?
12 to 18 inches
There is no universal rule for setting the distance but it’s recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
Are LED grow lights harmful?
The bottom line is that LED grow lights are no more dangerous than any other type of grow light. HPS is much more dangerous than LEDs – high heat and risk of burns, risk of broken bulbs and fires, high environmental damage due to mercury content, high carbon footprint.
How long should LED grow lights be on?
To be effective, grow lights really need to be on for at least 8-10 hours a day. This can vary up to 16 hours, depending on the conditions. That’s why LED grow lights are so popular – when they have to be left on all day, it’s best to use an energy efficient type!
What is the most efficient grow light for cannabis?
When it comes to improving your yields, the most efficient grow light is an HPS. When I say “efficient,” I mean the amount of usable light produced for the amount of electricity needed. Because HPS lights are so efficient, using an HPS light during your cannabis flowering/budding phase is the fastest way to improve your yields.
Are your LED grow lights too close to your cannabis plants?
If, on the other hand, you place your LEDs too close to your cannabis plants, this can stress the plants more than they can comfortably handle, causing burning and bleaching of the foliage and buds. So, what is the ideal distance between your grow lights and your plant canopy?
Are LED grow lights more efficient than HPS grow lights?
The truth is that when it comes to growing cannabis, LED grow lights are not currently more efficient than an HPS light when it comes to yields/watt. 400W of HPS will almost always get more yields from cannabis than 400W of LED. When it comes to improving your yields, the most efficient grow light is an HPS.
What are the benefits of HPS and LEDs for cannabis plants?
A combination of HPS and LEDs seems to provide some of the best benefits of both – big yields plus high quality and potency. This may be because a combination of HPS plus LEDs more closely mimics the autumn sunlight that cannabis plants are exposed to in the wild. Cannabis plants can use a lot of light,…
