cannabis seed sprouting time lapse

These have been circulating around the internet for a while, but if you haven’t seen them before, you don’t want to miss these bonus marijuana time-lapse videos.

Here’s a timelapse showing a plant putting its leaves up and down in response to the light

All plants do that. It partly has to do with their Circadian rhythms. Plants must put energy into keeping cell walls rigid to hold up the leaves. Kinda like using their “muscles”. With plants like cannabis, the leaves tend to “rest” at night and “perk up” when they “think” the sun is going to come out.

Growing with ScrOG Time-Lapse

After the plant is topped, notice that not just the top two, but all the growth tips on the plant begin growing out (the plant is becoming more bushy). This is due to a hormonal response that happens in the plant when the main cola is damaged.

While we don’t fully understand the mechanism behind this movement, some scientists speculate that it was developed as a way for the plant to “explore” and find the best direction to grow, since even though plants are rooted, the difference of even a couple of inches can make a huge difference in the survival of the plants.

Although this plant recovers, you can see how badly the burns stunted its growth, and you’ll notice that the regrowth that follows is a bit odd as the plant “ditches” the burnt parts and then gets back into the swing of things.

There will be a ton of foliage at this point and the plants will want more water than seems possible. Any training should be done at this stage, as long as the plant is healthy and growing rapidly.

This is where it all begins, the seed. During this formative stage of growth the cannabis seed, once planted or placed in a germination station, breaks apart and the spindly taproot emerges looking for nutrients.

The length of the vegetative stage of growth is dependent on the genetics of the plant, as well as the period of time they are receiving light. Plants can technically remain in the vegetative state pretty much indefinitely, but eventually, they will hit their max growth or the amount of growth comfortable for the room and need to be switched over to flowering.

The rest of the growth is up to the plant, but when it seems to be getting close to harvest time flushing nutrients is important for quality tasting harvest. Simply flush the plants with pH-balanced water and stop administering nutrients at this time to ensure a good harvest.

The growth of the plant will begin to slow down here as well, eventually stopping altogether as the plant’s energy will be focused entirely on the buds.

The first leaves should be developing at this point, which the plant uses to photosynthesize light into nutrients.

A healthy plant will start turning a more vibrant green color and those blades will finally start becoming sizable, it will start looking more and more like a marijuana plant at this point. Once these seedlings fully develop these initial leaves and blades, they will be considered maturing and move onto the next stage of growth.

Marijuana sales soared in 2020, from $10 billion the year before to nearly $18 billion. Experts say the pandemic played a major role. "I think people turned to cannabis to help relieve stress," says author of Weed the People Bruce Barcott.

A new study from researchers in Canada has found a higher likelihood of autism in babies born to mothers who used marijuana. Experts weigh in on what we know thus far.

Power players in the cannabis industry are actively working toward dismantling oppressive systems meant to incarcerate people of color prohibit them from finding success in what is now a multi-billion dollar industry.

Marijuana advocacy groups and the American Lung Association are warning about a link between marijuana smoking and a higher risk of serious infection from COVID-19.

The systematic review explored 36 case studies on cardiovascular health and found that many of the drugs used to treat heart conditions have the potential to interact with marijuana.
