Can plants die from too much heat?

What happens when a plant gets too much light?

Plants are supposed to crave sunlight, but too much sunlight can create potentially deadly free radicals. … But if the plants are exposed to too much sun, these molecules absorb more energy than they can handle and generate reactive species of oxygen that can destroy the plant.

Can plants get too much artificial light?

Most houseplants do well with 12-16 hours of artificial fluorescent light each day.

Plants deprived of light will grow upward, stretching their stems more rapidly that usual, searching for light.

Does more light mean faster growth?

Medium light plants can grow in the 15-watt range, but higher intensities of light can promote faster growth rates. High light plants require at least 20 watts per square foot of growing space, though higher intensities will further promote growth and flowering.
