Follow the chart below as a general rule of thumb.
Best type of light for growing weed.
There are two main types of hid lights.
The best led grow lights provide all the right wavelengths to grow big beautiful buds.
Many growers swear by hid lighting and believe that they produce the best and biggest yields.
Leds high intensity discharge hid bulbs and fluorescent lights.
High intensity lights are superior for growing cannabis because they produce more dense compact and higher yielding plants.
Just consider the extra amount of work and cost for setting them up including cables exhaust fan and fixture.
If it is efficiency you re after hid is probably the best grow light for marijuana available.
Then again if you have a grow space of less than five square feet fluorescent light is enough when your plants are small.
If in doubt always keep leds further away.
Make sure to get a digital ballast.
They use less electricity and bulbs will live longer.
Hid high intensity discharge grow lights are somewhat of a gold standard in the cannabis cultivation industry.
There are three main types of lights you can use to grow cannabis.
Plus they stay much cooler than their traditional.
Metal halide grow lights produce light by arcing an electric current through mercury gas mixed with some sort of metal iodide such as thallium thorium or sodium.
That is as long as you don t mind the increase in your electricity bill.
High powered lights such as a 1500 watt 2000 watt or 3000 watt led grow light should be raised to 24 36 above the canopy.
Researchers and experienced growers through extensive experimentation now understand that blues reds and ultraviolets are some of the most central wavelengths.
While cannabis requires a full spectrum of light to flourish it relies on some colors more than others.
The lamps are well suited for growing marijuana and if you are looking for the highest yield hps metal halide is the way to go.
The light that it produces falls into a perfect range of the color spectrum for the growing phase of cannabis.
While you can somewhat increase the intensity by moving the grow lights closer to the plants it s best to choose a high intensity grow light from the start.
It includes 60 high intensity bridgelux epileds chips in 12 different colours.
Among these are five led variations on the red spectrum four blue variations one infrared diode and 3000k warm white as well as 7500k cool white leds.
The viparspectra v300 grow light is certainly among the most successful budget leds for growing cannabis plants.
Mh metal halide and hps high pressure sodium lights.
