Vegetable seedlings and other “full sun” plants require about
2000 to 3000 lumens (at minimum) per square foot of growing space
. So, if you're growing just a single standard tray of seedlings, using a grow light that emits 3000 lumens is sufficient.
Is 5000 lumens enough for plants?
The optimal number of lumens is 7000 to 7500 lumens per square foot. For the plants that require minimum lightening, 2000 lumens per square foot is sufficient. … However, in the flowering phase,
5000 to 10,000 lumens are recommended

Most plant leaves do their best conversion with sunlight between
3,000 and 4,000 lumens per square foot
. … At a leaf's peak efficiency of 4,000 lumens per square foot, that leaves an optimal coverage area of 25 square feet—or a 5′ x 5′ footprint—for a 1,000-watt bulb.
Will 5000k LED grow plants?
Both 5000k and 6500k are great for the vegetative phase, flowering phase, and fruiting phase. So, they are ideal for the general growth of your plants. The only difference between 5000k and 6500k is that

Is 500 lumens enough for plants?
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.
Will 6500K LED grow plants?
Foliage growth is generally best around 6500K
, though many plants need a period of warmer light, around 3000K, in order to produce flowers, and thus fruit.
Can plants live off LED light?
But can you use any led lights to grow plants?

1000-3000 lumens per square foot
. Successful gardens usually are lit at around 2,000 lumens per square foot.
How strong should a grow light be?
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).
Is 10000 lumens too bright?
While I agree that
brighter is better
, 10,000 lumens would be blinding for oncoming traffic, which is not a good thing.
