Moving the grow light closer will increase the light intensity which can maximize photosynthesis. However, if the grow lights are too close above plants, they can cause wider, more sprawling growth or can even damage the plant. Plants require different levels of light depending on each stage of growth.
Considering this, how far away to put Grow lights from plants?
In general, you’ll want to hang your light no more than 12″ away from your plants. – Remember: after 12″ fluorescent lighting loses its power, so make sure you don’t raise it any more than 12″ above your canopy otherwise your plants aren’t getting light energy.
In respect to this, can you use T5 for flowering?
For the vegging stage of growth, you’ll want to use a T5 fluorescent grow light with a 6400k spectrum of light– that’s going to give you a white/blueish spectrum. When it’s time to flower you’re going to go with a 2700k bulb to give you a yellowish/white spectrum of light that stimulates flower growth.
How do you tell if grow light is too close?
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.
A: In general, you should not leave grow lights on 24/7. Plants need a light-dark cycle to develop properly. It’s believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
And since autoflowering plants have short vegetative phases and often grow shorter than photoperiod strains, you’ll typically want to give your autos at least 18 hours of light. This allows for robust growth, without overspending on energy.
T5 light to cover a 2-ft. by 4-ft. area.
On average, an LED T5 lamp is rated to last as long as 50,000 hours. This is more than double the standard 24,000 hour life of a fluorescent tube. Installing lamps with this long of a lifespan eliminates the need for frequent replacement.
LEDs also offer increased light efficiency when dimmed as opposed to T5 fixtures and usually produce more lumens per watt in general, which decreases energy usage and thus, energy costs. A lower wattage of LED luminaire will usually be just as efficient, sometimes more, as a higher wattage T5 lamp.
