So, during the vegetation phase, your 4×8 grow tent will need
at least 800 watts
of LED lights. Again, you can use a single light with 800W output or combine multiple lights to provide that. It's up to you.
Can you have too much LED light in a grow tent?
Cannabis plants will show a number of key signs when they're getting too much light
. The most obvious indicator is leaf burning. This typically causes yellow leaves at the top of the plant directly under the grow lights. While the inside veins stay green, the leaves take on a yellow, burnt look.

How many LED lights do I need?
To determine the needed lumens, you will need to
multiply your room square footage by your room foot-candle requirement
. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
How many watt LED grow light do I need?
As a rule of thumb, aim for
20 to 40 watts per square foot
. Divide the wattage of your bulb by 20 (such as 400 watts divided by 20 = 20), and then divide the wattage of your bulb by 40 (400 divided by 40 = 10). The answer gives you the extremes of your light intensity range.
How far should my 300w LED be from plants?
During the flowering stage LED Grow lights should be located
between 16-36 inches
from the plant canopy. Moving the grow light closer will increase the light intensity which can maximize photosynthesis.
Do regular LED lights help plants grow?
Regular LED lights can't be used as grow lights
, even though they may emit some of the wavelengths necessary for plants. Regular LED lights don't emit enough of the light that plants require. Plant growth primarily requires red & blue light, which LED grow lights are designed to maximize.
How long should LED grow lights be on?
To be effective, grow lights really need to be on for
at least 8-10 hours a day
. This can vary up to 16 hours, depending on the conditions. That's why LED grow lights are so popular – when they have to be left on all day, it's best to use an energy efficient type!
How many lights 5×5 grow tent?
The Yield Lab Pro Series 1000W HPS+MH Air Cool Hood Double Ended Complete Grow Light Kit is all about big coverage and intensity. This HPS and MH grow light kit will provide the necessary lumens to
up to 6 plants
in a 5×5 grow tent through the vegging and flowering stages.
How much can a 10×10 grow tent yield?
The 10′ x 10′ Indoor Grow Rooms will house
up to 32 medium plants or about 24 or so if you want them to get bigger than normal
. These monstrous grow tents will require an extra room or space in the garage to be set-up in since they are so big.
How many grow lights can I run?
There are
up to 12 lights
and or plugs on that circuit. A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit.
How much can a 4×4 grow tent yield?
The final yield in a 4×4 grow space is
1.5-2 lbs
. Also, because the plants are large in size, ScrOG or single plant growing is preferred for maximum yield.
How many plants can a 600w LED grow?
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
.
How do I calculate how many LED downlights I need?
A general rule of thumb for spacing your downlights is to
take the height of your ceiling and divide by 2
. For example, if your ceiling is 8 feet high, then your downlights should be around 4 feet apart from each other.
How many luminaires do I need calculator?
Calculate the amount of lumens you need. Multiply the area in square meters by the lux, or the area in square feet by the footcandles. Work out how many bulbs you need. Divide the number of lumens by the number of lumens delivered by each bulb.
How many downlights do I need calculator UK?
If you're looking for the short answer to this, you can install
1 downlight per square metre
, leaving 1 metre spacing's between each downlight and a distance of 1/2 a metre from the walls. This would generally get you the correct, bright and even lighting results.
What size tent do I need for 2 plants?
Here is a quick guide to sizing your tent with how many plants you can grow:
2′ x 2′ Grow Tent
– Great for mother plants (1-2 plants) 2′ x 4′ Grow Tent – Fits in most closets (2-4 plants) 3′ x 3′ Grow Tent – Ideal for people with a limited work area (2-4 plants)
How is LED wattage calculated?
To calculate an LED's power use, simply
multiply the LED's voltage (in volts) by the LED's current (in amperes)
. The result, measured in watts, is the amount of power your LEDs use. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power.
Can LED lights burn plants?
While LED lights do produce some heat, they deal with that heat more effectively than other light types. Plants can grow much closer to LEDs than other lighting types because of this.
Usually crops can grow right up to the light without burning
.
How many Umols are needed for flowering?
Under normal home-scale operations, cannabis typically needs a PPFD of between 100 – 300 μmol/m2/s during the seedling, 400 – 600 μmol/m2/s during vegetation, and
800 – 1,000 μmol/m2/s
during flowering. These are the basic required food photons to grow a healthy and strong weed.
How do you know if a light is too close to a plant?
The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage.
If some of the leaves start curling up
, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue.
Will 5000K LED grow plants?
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 LED is best for plants?
We could say that the two most important light colors to place in an LED lamp are:
red and blue
. Red is the main component that plants need for photosynthesis and stem elongation inhibition. Additionally, it signals to the plants that there are no other plants above it and that it can thus have uninhibited development.
What is the difference between LED lights and LED grow lights?
What's the difference between LED lights and LED grow lights?
Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering
, respectively.
