What color LED for veg stage?

Blue Light

Every photobiology study out there recommends Blue light to be lower than 30% for optimal results during vegetative growth for flowering plants. If you could get that down to 15% it would be even better. If you have Red/Blue/White switches, try your results with just “Red” and “White” turned on.

Likewise, what color light is best for plant growth? Different color light helps plants achieve different goals as well. Blue light, for example, helps encourage vegetative leaf growth. Red light, when combined with blue, allows plants to flower. Cool fluorescent light is great for cultivating plant growth indoors.

Considering this, what bulb is best for vegetative growth?

One technology that revolutionized lighting for indoor vegetative growth is the T5 fluorescent. T5 fluorescent lights are high-output fluorescents and are capable of producing great vegetative growth. Some old-school growers may remember using T12 or T8 fluorescents for growing plants.

Can LED lights burn plants?

LED lights tend to produce less heat than older technology, and their light intensity is relatively low. This has lead to the conclusion that you can put plants as close to the lights as you want and you won’t burn them. This depends very much on the plant, but a PPFD of 800 is enough to damage some plants.

Will 5000k LED grow plants?

Go higher than 5000K, and so much red light is left out from the spectrum your plants will grow slowly and without much vigor. But at the end of the day, plants will “veg” and “flower” under any kind of light.

Do LED lights take longer to flower?

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.

Can you mix HPS and LED?

Hybrid lighting systems, consisting of High Pressure Sodium (HPS) and full spectrum Light Emitting Diode (LED) grow lights, can be used together to grow and flower plants – outperforming HPS-only lighting systems.

How far should 300w LED be from plants?

LED Grow Lights Type of LED Grow Light Distance From Plant 1W Bulbs at least 12″ (30cm) 3W or 5W Bulbs at least 18″ (45cm) High Wattage (300W+) up to 30″ (75cm) or more

Will blue LED grow plants?

Blue light is a specific light wavelength that is needed by plants for photosynthesis and growth and is ideal for use on seedlings and young plants. Blue LEDs are far more efficient than they were a few years ago and are useful in grow light systems in combination with other light wavelengths.

Why does red light make plants grow faster?

Red light fits with the absorption peak of chlorophylls, which do photosynthesis to produce sugars and carbons1. Sugars and carbons are essential for plant growth, as they are the building blocks for plant cells. For this reason, red light increases photosynthesis rate and plant size2.

How far should I keep LED lights be from plants?

The G8LED 240 Watt LED Grow Light is for 2-4 mature plants, with a distance of 12-24 inches from the top of the canopy. The larger G8LED 450 Watt LED Grow Light is for 4-8 mature plants, with a distance of 14-30 inches from the plant canopy.

How many watts veg stage?

A good rule of thumb is that between 10-20% of your total light wattage in the Flower Room will be used in vegetative growth. This means that if there are 50,000 watts in the Flower Room, there should be between 5,000 and 10,000 watts in the Veg Room.

How much light is in the vegetative stage?

The plant can receive as much as 24 hours of light a day while in the vegetative stage. Many indoor growers provide 18-24 hours of light a day (known as 18-6 or 24-0 light schedules) during the vegetative stage to encourage faster vegetative growth.

What light do I use for vegging?

CFL’s and fluorescent tubes (High Output T5’s are good) work well for vegging. They typically cost less than a metal halide ballast, bulb and reflector but still veg effectively. But MH will give the most light penetration.

How many lumens do plants need?

The optimal light would be 7000 to 7500 lumens per square foot. If the plant only requires minimum lighting, it should be approximately 2000 lumens per square foot. For the mid-range measurement, it should be approximately 5000 lumens per square foot.

Is metal halide better for veg?

HPS is about twice as electrically efficient as metal halide. Photosynthetically Active Radiation (PAR) is what really matters to plant growth, and delivery of usable PAR is better with HPS than metal halide. The enhanced blue in metal halide does not lead to increased plant growth compared to HPS in the “veg” stage.

Can I use HPS for veg?

and you can absolutely veg under HPS and you’ll get lots of growth, but the downside is you’ll get taller, stretchy plants with lots of distance between the nodes so you end up with lots of smaller buds spread over a lankier plant rather than fewer, larger buds because, being shorter and bushier, the buds grow together

What is the best Kelvin for vegetative growth?

Bulbs that are more blue are called “Bright white” or “Daylight” colored and are listed with a Kelvin of 5000K / 6500K. These “high kelvin” bulbs are optimal for vegetative growth. These CFL bulbs mimic the color temperature of the sun during Spring/Summer.
