You can use standard full-spectrum white light LEDs to grow cannabis… Standard full-spectrum (white colored light) LEDs will contain some amount of light from all the color spectrums (violet, blue, green, yellow, orange, red). Since then, LED grow lights have been improved to produce even better results when growing marijuana. You may or may not know about the LED grow light craze for marijuana growers. LED grow lights use less energy and generate much less heat than standard HID grow lights, so there's good reason for all the attention. How To Make Buds Bigger During Flowering Increase Your Light Intensity. I'm sure you're aware that in general, more light generally means a larger yield. Dark means dark! Ensure Air Circulation / Co2. Pruning. Get Rid Of Any Male Plants. Adjust Your Fertilizer To Match Your Plants Requirements. Harvest At The Right Time. Regular incandescent bulbs get quite warm, and they aren't all that energy efficient. They give off more red wavelength light than white. Yes, you can grow a plant with them, but it's not the best idea. Ceramic Metal Halide (CMH) & Light Emitting Ceramic (LEC) Grow Lights HIDs are the most efficient type of grow light (gets the highest yields/watt). Of all the HIDs, HPS grow lights are the most efficient and the best for the flowering stage.
As a rough guide, incandescent grow light bulbs should be at least 24 inches over your plants. Fluorescent and LED lights have a lower heat signature, so they can be placed 12 and 6 inches over plants respectively.
You may have heard that one big drawback of LED grow lights is flowering time. They simply take longer to flower. They often don't have enough power to bloom, or they simply have an ineffective spectrum. The reason HPS bulbs flower so well is a light spectrum that is heavy in red.
How Many Plants Can I Grow? Grow Space Size Minimum Number of Watts Required Number of Plants You Can Grow 6 sq ft (2×3) 300w 1-6 plants 9 sq ft (3×3) 450w 1-9 plants* 12 sq ft (3×4) 600w 1-12 plants* 16 sq ft (4×4) 800w 1-16 plants*
2 month plants should give about 40g per plant, so with about 9 you'll be able to easily fill a square meter and get up to 400g per 600w light. 3 month autoflowering plants grow much bigger, however, so you should only plant 4 per 600w light.
To keep it short, Yes, you can technically leave grow lights on 24 hours per day, but this is only during the vegetative state of growth. Some people choose to only leave the lights on for 18 hours per day, even in the vegetative state of marijuana growth, which is for good reason.
Most indoor growers provide 18-24 hours of light a day (known as 18-6 or 24-0 light schedules). Giving your cannabis plants more hours of light each day in the flowering stage will encourage faster growth.
LED grow lights are great because they are energy-efficient, durable, and have 'tuned' light spectrums to best meet the plant's needs. However, there are still many excellent fluorescent grow lights that are much cheaper and still contribute to wonderful plant growth.

Halogen bulbs are a variation of incandescent. They give the closest approximation of natural daylight, known as "white light. " Colors appear sharper under halogen light and the bulbs can be dimmed.
Go higher than 5000K, and so much red light is left out from the spectrum your plants will grow slowly and without much vigor. They don't “need” blue for veg and they don't “need” red for flower, heck, they'll even grow under a completely green light source from start to finish!
Unfortunately, due to the heat entrapment of enclosed fixtures, not all LED light bulbs can be used. Or perhaps it is better to say that they should not be used. It may still be possible to use your regular LED bulb in the enclosed fixture, but with a shortened life span and the potential for premature dimming.
LED light can damage eyes, health authority warns. The "blue light" in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness.
You can grow plants with white LEDs. The bulbs sold at hardware stores are slightly more efficient than 23 watt CFLs, however they are less efficient than T5s or metal halide bulbs.
Yes, in many cases, you can simply replace your bulbs separately, one by one. Replacing your existing incandescent or halogen bulbs with durable LED bulbs offers numerous benefits. You enjoy an even better light performance and benefit from very low energy consumption.
