Is metal halide better for veg?
MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.
What is the best light for vegetative growth?
MH lighting is one of the most popular choices for vegetative growth among indoor gardeners. The high amount of blue light emitted by MH bulbs makes this particular type of lighting an attractive option.
What color light is best for vegetative growth?
Blue lights
Blue lights with a Kelvin color temperature from 5000K to 6500K or wavelength in the 400-500 nanometer range are best for the vegetative stage of the grow cycle and for starting seeds indoors.
How many watts LED for veg stage?
Assume about 32 watts/sq ft (actual LED wattage) for flowering. Fewer watts might equate to smaller yields while more wattage may lead to larger yields….Recommended wattage assuming 1.0 sq ft/plant.
| # of Plants | Square Feet | Wattage from Wall |
|---|---|---|
| 1 | 1 | 30 to 40 watts |
| 2 | 2 | 60 to 80 watts |
| 4 | 4 | 120 to 140 watts |
| 6 | 6 | 180 to 200 watts |
Can you veg with LED lights?
Most LED grow lights you can find today are “full spectrum” lights, which is sort of a buzzword that means you can use them for vegging and flowering. But there are also models outfitted with a switch that allows you to change the light spectrum according to the phase.
What color temperature is best for vegetative growth?
5,000 – 7,000K
As a general recommendation, choose a full spectrum grow light with a color temperature in the blue range (5,000 – 7,000K) to promote vegetative growth and choose a color temperature in the red range (3,500 – 4,500K) to promote fruiting and flowering. Visible Light Spectrum.
What color causes the most plant growth?
Chlorophyll is what makes plants green and allows plants absorb light energy and turn it into food. Since chlorophyll is green, colors on the opposite side of the color spectrum are most efficient for plant growth including red and blue.
Can you veg with HPS lights?
In response to the general question, can you use an HPS bulb for veg, the answer is yes.
What is the difference between metal halide and ceramic metal halide?
The largest difference between MH and CMH lamps is the Ceramic or “C” in CMH. This refers to the arc tube material, which is made of a ceramic material – similar to what is used for HPS lamps.
How many watts do I need for vegging?
Recommended wattage assuming 2.0 sq ft/plant
| # of Plants | Square Feet | Wattage from Wall |
|---|---|---|
| 1 | 2 | 60 to 80 watts |
| 2 | 4 | 120 to 140 watts |
| 4 | 8 | 240 to 300 watts |
| 6 | 12 | 360 to 400 watts |
How many plants can you grow with 1000 watt LED?
Yield Lab 1000W HPS+MH Cool Hood Reflector Grow Light Kit (Price: $239.95) — With a 1000w grow light, you’ll get 130,000 lumens from an HPS bulb and 110,000 lumens from an MH bulb. That’s sufficient to provide coverage for up to 6 plants.
Is 5000K good for veg?
In general, plants can survive within the color temperature range of 2700K-7000K, so both 5000K and 6500K are within an acceptable range.
What color produces the most oxygen?
Green produced a total of 6.09 milliliters of oxygen, red produced 3.96 milliliters of oxygen, yellow produced 2.89 milliliters of oxygen, clear produced 2.17 milliliters of oxygen, and lastly blue produced 1.71 milliliters of oxygen.
Is it better to grow plants under blue and red light?
While red is most efficient for photosynthesis, having only red light would result in poor growth such as very elongated stems, so blue is added to keep plants compact and a more typical shape.
