Q1. How long should plants be under a grow light?

A: Plants do require a daily respiration period of at least 6hous per day (or seeding) and  ideally 8-10 hours for more mature plants. Therefore we do not recommend d providing more than 14-16 hours per day of light,even if you are growing long-day-  loving varieties and trying to induce flowering/fruit from them.

Q2.Do grow lights use a lot of electricity?

A: It actually depends on the size of your grow space. As a rule of thumb, you will need 30 to 40 watts per square foot. That is, if you have only one plant, you will need only 30 to 40 watts of power.

Q3.Will grow lights burn plants?

A: Light, even intense light, probably won't burn your plants. If a plant is getting too much light, it can challenge your crops and be counterproductive, but it won't actually cause burning.

Q4. How do you use LED lights for indoor plants?

A: LED grows lights should be placed from 14 to 30 inches above the plants. One of the biggest advantages of using LEDs is that they put off so itte heat. So, you can place them close to your plants without worrying about burning them.

Q5. What LED lights are best for growing?

A: Light Spectrum. Some LED lights can reproduce only certain color frequencies, while fl-spectrum white LED lights produce all the hues necessary for every stage of the growing process Blue  light helps plants grow in the earliest stages of their lives.
