Question: How many lumens do I need for a grow light?

There may be no ideal amount, but, generally, if you can produce somewhere between 300 and 800 lumens per square foot your plants should prosper quite nicely.

Is 5000 lumens enough for plants?

For the mid-range measurement, it should be approximately 5000 lumens per square foot. … If ever you are in the vegetative period, approximately 2000 to 3000 lumens per square foot would be the minimum amount. If your plants are on the flowering phase, 5000 to 10000 lumens per square foot is recommended.

Can any LED light be used as a grow light?

You can use any LED bulb to grow plants if they are emitting enough light. Plants often also look for warmth to come from the light source and we know LED bulbs do not provide much of that.

How much area does a 600 watt LED grow light cover?

The wattage of the light will determine how much area you can light up. If we assume that the plants will get no sunlight, a 1000 watt light will cover about 7×7 feet of growing area. A 600 watt will cover 6×6 feet, a 400 will cover 4×4 feet, a 250 will cover 3×3 feet and a 150 will cover 2×2 feet.

How many lumens do you need to grow a seed?

The brighter the light, the better it will be for your seedlings. Remember, we’re trying to mimic the sun on a warm mid-summer day (~10,000 lumens). Plants growing outside receive the full spectrum of light, but they don’t use all of it all the time. Seedlings need the cooler, blue light waves to thrive and grow.

Will 5000K LED grow plants?

The reason for this, is that at the “warm white” color temperature, the “ratio” of wavelengths is ideal for 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.

Is 3000 lumens too bright?

In other words, 3,000 lumens is meant to give a room a brighter light. This is not ideal if you have a small room and it’s a bedroom. You don’t want to blind your eyes when you’re about to go to bed. On the other hand, 2,000 lumens is ideal if you wish to light up a 200 square-foot living room.

What is the difference between grow lights and regular lights?

Obviously, these are two very different lights used for very different purposes. Grow lights are very specifically constructed to aide in various stages of plant growth. Regular lights are made for everyday use, and although many are used for specific purposes, they all are based on human needs and consumption.

Should I run my grow lights at night?

Plan on giving most plants at least 8 hours of darkness per day. Darkness is actually very important for the plant growth cycle. During the day, sunlight helps plants produce energy through photosynthesis. At night, however, plants break this energy down for growth and flowering in a process called “respiration”.

What color LED light is best for plants?

Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.

How many lights do I need for 12 plants?

the general rule of thumb is 25-50 watts of light per square foot, you have 100 sf, so you need 2500-5000 watts of light. Check out the led forums here, they seem to be the way to go, especially if heat is an issue.

How many plants can a 1000w LED light grow?

How Many Plants Can I Grow?

Grow Space Size Minimum Number of Watts Required Number of Plants You Can Grow
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*
20 sq ft (4×5) 1000w 1-20 plants*

How much does it cost to run a 600 watt LED grow light?

Multiply $0.0195374 by the number of hours you plan to run the lights (14 hours). The cost to run the lights per day is $0.2735236 or $8.20 per month. If I have an HID (high intensity discharge) light with a 600 watt bulb in it, using the same method of calculation, it would cost me $30.90 per month.

How many lumens do LED grow lights produce?

There may be no ideal amount, but, generally, if you can produce somewhere between 300 and 800 lumens per square foot your plants should prosper quite nicely.

What color temperature do plants grow in?

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. Wavelengths in nm.

What color light promotes germination?

Suffice it to say that it is mainly the light’s effect upon a plant pigment called phytochrome within the seed. This relates to the type of light which the seed receives. As a generalisation, light in the red wave length usually promotes germination whereas blue light inhibits it.
