Today I would like to feature the following incredible marijuana growing time-lapse photography and videos, many of which were produced by fuzzygrow. View all of her time-lapse videos here: http://vimeo.com/user15676933/videos
A huge thanks to fuzzygrow for contributing these uniquely valuable time-lapse videos to the marijuana growing community!
This time-lapse video spans 5 days, a frame was taken every 6 minutes. 24fps.
Watch two seeds sprout and grow their first two sets of leaves. The plant on the left is Super Lemon Haze and the one on the right is strain Tijuana.
Marijuana seeds first sprout two smooth “baby” leaves known as cotyledon leaves. These leaves were already formed in the shell. When the seed is put in warm wet conditions, the seeds “wake up” and the seed splits open. The white tip that first emerges becomes a root and grows downward.
The cotyledon leaves unfurl and start gaining height above the soil. You can see the first “true” (wrinkled) set of marijuana leaves nestled in between the cotyledons at first, and as time goes on these spread out to catch as much light as possible.
You may notice the young seedlings making slow circular movements. As far as we know, all plants do this while they grow and this movement is known as nutation, circumnutation, or nutational movement.
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.
This time-lapse video spans 7 days
In this video, a young marijuana plant is topped and you can watch as the two growth tips from the top node (quick picture cheat sheet explaining nodes & growth tips) turn into the two new main colas.
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.
Watch as the two new main colas at the top get wider and taller, while their connection to the base of the trunk is strengthened and thickened to support their growth.
This time-lapse video spans 2 weeks, a frame was taken every 6 minutes. 30 fps.
The insecticide is sprayed while the lights are on, and unfortunately this combination of insecticide + light burns the young plant. You can see the plant struggles to recover for nearly the rest of the video.
I sprayed Dr. Doom on this young plant to try to combat spider mites. Plant is under a 42w CFL. The main apex was also burned which stopped growing but eventually a new one formed off center. New leaves sprouted just above the cotyledons as well.
Don’t spray pyrethrum-based products with any grow lights still on!
Pyrethrum is an ingredient in certain insecticides. In this case it came from Dr. Doom. Pyrethrum is very photoreactive so because it was sprayed with the lights on it created a bad situation on the plant as you can see. It almost appears to burn it. The growth was very gnarly for awhile afterwards!
You can see the extreme stress the Pyrethrum combined with grow lights has put on the young plant.
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.
Growing with ScrOG Time-Lapse
Watch as these young plants are trained to fill up a ScrOG net. ScrOG stands for “Screen Of Green” and refers to using a “screen” (usually made of string) to force plants to grow into a flat canopy.
The above time-lapse video spans 40 days of growth. A frame was taken every 6 minutes. 50fps.
Once the screen has been “filled out” with vegetative growth, the grower will switch to the flowering stage. The ScrOG technique is used to get better yields out of your indoor grow lights, which are most effective when plants are kept as close to the lights as possible. The ScrOG technique makes it so that when buds start forming, the lights shine directly on the buds and fatten them.
You just saw these plants fill up the ScrOG net in the last video. Now watch as the colas from these scrogged plants fatten up throughout the flowering stage until harvest time.
Why do marijuana plants seem to “breathe” in time-lapse photography? Why do the leaves begin to droop down and then suddenly spring back up?
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.
The plants also wilt when they’re thirsty and perk up after being watered.
Here’s a timelapse showing a plant putting its leaves up and down in response to the light
