The flowering stage of a plant’s growth is determined by a biological process called photoperiodism. This process controls the threshold for light necessary for flowering. Once a plant reaches the flowering phase, its photoperiod goes from flower-restricting PFR to flower-neutral PR. Plants are extremely sensitive to light during this period. It is therefore important to give them the right amount of light during this period to maximize trichome production.
Plants need at least 13 hours of light each day to stay in veg
To trigger flowering, cannabis plants require 12 hours of darkness each day. During the first few days of flowering, these plants stay in a vegetative stage. This state is maintained until they reach a certain threshold. The threshold is usually ten hours of darkness each day. If you don’t provide the proper amount of light, your plant will remain in the vegetative state for as long as it takes.
Ideally, plants require at least 13 hours of light each day to be able to flower. The longer the veg stage is, the bigger your plants will get and the more fruit they’ll produce. To lengthen this period, some growers run the lights for 24 hours each day. However, there is a major disadvantage to this method. While plants can grow bigger and produce more fruit if they receive more light, the main drawback of this method is the fact that the plant won’t get any rest.
Plants require more light during flowering
When a plant is in its flowering stage, it requires more light than it needs during the vegetative stage. This is due to a process known as photoperiodism. This process helps plants and other organisms determine the threshold of light needed to stimulate flowering. After about two weeks, plants go from flower-restricting PFR to flower-neutral PR, and they are highly sensitive to light during this time.
Light is essential for plant growth because it feeds the plant with energy, which is used for photosynthesis. Without light, photosynthesis cannot occur, which releases oxygen into the atmosphere. Photosynthesis relies on sunlight and artificial light to produce energy and feed plants and all life on our planet.
Blue light is best for trichome production
There are many reasons why blue light is better for trichome production during flowering. Plants that are exposed to blue light are more compact, bushier, and produce more resin. It is important to use the correct light spectrum for your cannabis plant. The wrong type of light will cause it to grow tall and stretchy, and it will lower the overall yield of your harvest. Blue light also amplifies the concentration of trichomes and oils. UVB light is also dangerous for plants, putting them on the defensive. This is why plants produce trichomes to protect themselves.
The chemical composition of trichomes varies. The stalked trichomes have a unique chemical profile. The terpene profile of stalked trichomes is mostly monoterpenes (92%). The sessile trichomes have a large number of sesquiterpenes.
Avoiding lamp burn
The most important factor in avoiding lamp burn during flowering is to reduce the relative humidity. This is because flowering plants tend to be sensitive to high relative humidity, which can lead to rot. The ideal temperature range for flowering plants is 68-82 deg F (20-27 deg C). Another important factor is to keep the foliage of your plants away from the light source, but not too far away that it is obstructing the lighting. Keeping foliage away from the lamp also prevents stretching. Also, it is best to do any major pruning during the veg period, not during flowering.
Pruning during flowering
Pruning during flowering is a common practice that many growers perform. However, this practice can actually be detrimental to your plants. Pruning too late will cause your plant to undergo further vegetative growth, reducing the overall yield. Instead, prune your marijuana plants during the first two to three weeks of flowering.
Pruning during flowering is not necessary, but it is a common practice that can help you harvest more from your plant. Proper pruning will remove between 20 and 40 percent of the foliage every five to seven days, which will help your plants capture more valuable light. More quality light will help them produce more flowers and mature more quickly. Pruning during flowering will help your plants thrive, but you should be careful not to cause damage by pruning too much.
During flowering, you should avoid pruning your cannabis plants too hard, which can cause them to stop flowering. Cannabis plants need to be at least 12 inches (30 centimeters) tall and have several sets of leaves before you begin pruning them. Heavy pruning will prevent your plants from flowering, so you should only perform pruning during flowering if you are confident in your abilities.
