How do you know if your plant is getting too much light?
Can Plants Get Too Much Light?
yes, there are two ways plants can get too much light. Firstly, light that is too intense can damage your plants. Secondly, excess light duration can affect the growth cycle and blooming of many plants. Limits of light intensity and duration varies between plant species.
How much light a cannabis plant could possibly get in outdoors?
That being said, there is definitely a desirable range when it comes to the amount of light a cannabis plant receives. Although that range varies depending on the type of plant (Indica vs. Sativa) and strain, most plant’s ideal light levels fall into the range below:
Vegetative: 35,000 – 70,000 lux
Flowering: 55,000 – 85,000 lux
How to get light when grow indoors?
led grow lights for cannabis have been a good choice for growers.
There are two things to consider here: light duration and light intensity.
Light duration refers to the number of hours of light a plant receives each day while intensity is the quantity of light per unit area, usually measured in Lux or foot candles.
Each of these is a different concept and affects a plant’s growth in different ways. Generally speaking, light intensity is what you need to be careful about. Let’s take a closer look.
For the most part, plants can be exposed to light for an indefinite amount of time and still continue to grow.
However, being exposed to light for too long can affect a plant’s growth cycle and ability to bloom but this differs based on the type of plant. Interestingly, plants actually grow faster at night due to important metabolic processes that happen at night.
Light intensity is what causes most of the negative effects associated with a plant getting too much light.
When a plant is exposed to high intensity light, some of this light energy is converted to heat. Your plant must take steps to dissipate this heat energy, which normally involves using some of its available water to cool itself off.
Over time, this can deplete the plant’s water reserves and leave insufficient water for vital processes such as photosynthesis. If the plant’s capacity to dissipate heat is depleted, or if the amount of heat generated exceeds the plant’s ability to dissipate it, the plant will suffer heat damage. This often presents as yellow or brown spots on the foliage, generally yellow leaves, brown crispy leaf edges or tips, or curled, dropping leaves.
What symptoms your plant is getting too much light?
- Brown leaf edges or tips
- Brown, dry patches on the leaves
- Leaves turn pale or yellow, particularly those most exposed to the light
- Yellowing may be noticeable in the leaf tips first
- Leaf yellowing may not affect the leaf veins initially
- Wilting, particularly of younger foliage
