Fun Facts

Cannabis plants can “see”

Think about this: plants see you.

In fact , plants monitor their visible environment all the time. Plants see if you come near them; they know when you stand over them. They even know if you’re wearing a blue or a red shirt. They know if you’ve painted your house or if you’ve moved their pots from one side of the living room to the other.

Of course plants don’t “see” in pictures as you or I do. Plants can’t discern between a slightly balding middle-aged man with glasses and a smiling little girl with brown curls.

But they do see light in many ways and colors that we can only imagine. Plants see the same ultraviolet light that gives us sunburns and infrared light that heats us up. Plants can tell when there’s very little light, like from a candle, or when it’s the middle of the day, or when the sun is about to set into the horizon.

Plants know if the light is coming from the left, the right, or from above. They know if another plant has grown over them, blocking their light. And they know how long the lights have been on.

This is an excerpt from What a Plant Knows: A Field Guide to the Senses by Daniel Chamovitz. I highly recommend this book if you want to learn more about plants and exactly how they perceive the world!

Cannabis seeds can germinate almost anywhere warm and wet

Life Finds A Way

“My friend accidentally grew this in her sink. How is this even possible?”

Seedlings have enough energy (“food”) stored in the seed to make their first set of leaves. After that, they need light and nutrients to grow further. Unfortunately, this seedling won’t make it unless transplanted to a more suitable growing environment.

Cannabis plants are always moving

This constant movement is something that all plants do and is known as “Circumnutational Movement” (wikipedia link).

Nothing can really show you as well as watching a time-lapse video:

Every once in a while, growers will run into a “trileaf” seedling. This is a relatively common mutation, and you’re likely to run into it if you germinate a lot of cannabis seeds. 3-leaf cannabis seedlings should generally be treated like any other seedling.

They will grow about 1/3 more side branches than regular seedlings, so a 3-leaf seedling might be a good candidate for cannabis plant training or a ScrOG setup.

2.) Two-Toned Leaves

Two-toned leaves usually have split coloring in a relatively straight line. This mutation often affects just one or two leaves on the whole plant, though sometimes you’ll get a whole stem or part of the plant that displays this characteristic.

The two-toned leaves don’t seem to have much effect on anything, but it’s kinda cool looking!

I believe this happens due to a type of “variegation” (wikipedia link) and may be due to “sectorial chimera”. Other plants besides cannabis plants can have this happen, too!

Not to be confused with a nutrient deficiency, this mutation usually affects just one or two leaves on the plant. Nothing to worry about! Sometimes half of the leaf will turn purple…

More commonly, half of the leaf will turn light yellow or even white.

Cannabis leaves that are growing buds
(these cannabis plants have THC-encrusted buds growing from center of leaves)

Bud growing on center of cannabis leaf - mutationThis cannabis plant was covered in buds, but then the buds started growing right ouf the leaves, too

This is a mutation I’d love to see on my plants one day :slightly_smiling_face: Though strangely placed, these buds are like any other buds found on the plant. You just get a couple extra buds encrusted with THC & trichomes!

The following leaf-bud has grown a single calyx with a few pistils

4.) Uncommon mutation – Plant naturally topped itself

What’s interesting about this case is that the plant naturally did something that the grower would normally have to do themselves. Cannabis plants normally grow in a triangle tree shape, and growers often must cut or train the plant in order to grow more low and bushy.

Growers sometimes accomplish a low and bushy growth pattern with a plant training technique known as “topping.” Learn more about topping

Here are two normal young cannabis plants, each with a regular growth tip (set of leaves) at the top:

Normal cannabis plants

A regular healthy young cannabis plant with a growth tip on top

A green, healthy cannabis plant with normal growth patterns

So to get rid of this top growth node, a grower would normally cut it off, like this

Now the following plant had a strange mutation…

This plant randomly grew a leaf instead of a growth node, so it naturally topped itself, take a look!

5.) Some Buds Make “Fox Tails”

Bud with little foxtailing – common with Indica-based strains
(buds are rounded out, sometimes one foxtail visible near the top)

This Critical Hog bud grew in a classic cannabis shape, often associated with Indica strains

Massive foxtailing can be a genetic trait, and certain strains will tend to produce foxtails all over their buds no matter what. This seems to happen most commonly with Haze and Sativa-based strains.

This way that buds can grow is named after “foxtails” because the buds tend to grow in a rounded shape with the fluffy hair-like pistils coming from the end.

Example of healthy foxtailing based on genetics
(notice how there are foxtails all over the bud, instead of just at the top)

Marijuana buds making healthy foxtails based on genetics

Huge thick cannabis flowers - natural foxtails due to the genetics

However, massive foxtailing is often the result of heat or stress . You know that’s likely the case when the foxtailing seems to be happening mostly in the parts of the plant that are close to a heat or light source.

When a single foxtail keeps growing longer and longer , it is almost always a sign of some sort of major stress to the buds, most often heat.

This massively long foxtail was caused by heat
(it’s basically a very long and thin bud, and will likely never fill out)

7.) Cannabis Seeds Can Carry “Twins”

Twin tap roots can sometimes emerge from one cannabis seed. This is sort of like your seed having twins, because each new root has the potential to form into a separate plant!

When this seedling sprouted, it had two taproots coming from the same seed

This cannabis seed germinated with two tap roots - "twins"

When the leaves appeared, there were two distinct seedlings – you can see another tiny set of leaves behind the main sprout

Twin seedlings - two sets of cannabis cotyledons (first round leaves) coming out of one seed

In this case, I decided to kill the smaller sprout, but you can also gently and carefully separate the two seedlings and transplant one into a new home.

Example of "twin" cannabis plants (two seedlings from just one marijuana seed)

If you grow two seedlings together in one container, one plant will usually end up being a lot smaller than the other one. But if you give each plant their own home, they can both thrive!

8.) Leaves with Strange Number of “Fingers”

It’s normal for cannabis leaves to have a different number of fingers.

First, let’s go over what’s normal

For an adult cannabis plant, the most common number of fingers is 7. Here are a few examples of 7-fingered leaves.

7 Finger Leaves
(7 points is common for adult plants)

An example of a 7-finger cannabis leaf (most common type of leaf for adult cannabis plants)

Cannabis leaves start smaller though, with fewer fingers. Here’s what leaves generally look like from seedling to adult.

Next, the single-finger leaves expand, and the next set is usually 3-finger leaves

Next, the cannabis plant will start making 5-finger leaves

Finally, most cannabis plants stop at 7-finger leaves

If you look closely at the above plant, you can see that some of the newer leaves on this plant actually have 9 fingers. Here’s an example of a leaf that has grown 9 fingers:

9 Fingers

Cannabis leaf with 9 "fingers" or points

It’s completely normal for cannabis plants to have 9, 11, or even 13 points on their fingers. This is just a natural way that some leaves grow. It’s also common to get single-blade leaves growing directly off your colas.

9.) It’s Possible to Bleach Plants With Too-Bright Light

Light Bleaching – most common with high-power LEDs, but can also happen poorly ventilated HPS lights that are kept too close to the tops of the plants. Basically, this is what happens when plants get too much light, kinda like how the hair on top of your head can turn lighter if you spend a lot of time in the sun.

White tip of this "albino" cannabis plant is actually caused by light bleaching

A closeup of the bleached part of a cannabis bud that was given too high levels of light

Buds which have been bleached tend to be low potency or even have no potency (no available THC or other cannabinoids). Therefore you should avoid light-bleaching your plants at all costs!

Text-book example of light bleaching cannabis making the buds white - this bleaching was caused by high-intensity LED grow lights

Sometimes light-bleached cannabis will get mislabeled as “albino cannabis” or “white cannabis” but the truth is that the white color is not healthy, so this is not a desirable trait (even if it looks pretty cool).

10.) Flowering Cannabis Plants Can Make “Sap”

Sap – there’s lots of speculation about what it is. No one knows for sure. Many growers who have run into this agree that the type of sap produced is sweet and doesn’t contain much (if any) THC. It is mostly made of sugar and water and so is not smokable. Seems to be related to the plant over-producing sugars, and sap productions is more common when

  • Plants being in the flowering stage
  • Using sugar supplements like molasses, Botanicare Sweet, Sugar Daddy, etc.
  • Big temperature difference between night and day, especially if it gets cold at night
  • Certain strains or individual plants seem more likely to produce sap
  • Yet sometimes oozing sap seems to happen for no known reason

“Strain: Kosher Kush. Flowered her for 70 days and she was covered in trichs. When we harvested her we noticed about a dozen of these sap like globes. They range in color from clear to amber.”

~ DC514

Cannabis "sap" appearing on buds - unfortunately this sap is mostly sugar water with little to no potency

“The plants had already been flushed properly – I let the soil dry completely and fed the plants 2TBSP/gallon of molasses, let them eat and then flushed them out again and waited 2-3 days before harvest. Both plants started producing excretions all over. I’ve seen this before, sap leaking from the stem of plants, however personally I’ve never seen it on the buds themselves. What I believe happened is the pores of the plants either get clogged and therefore “pop” for lack of a better word. Or, the plant liked the molasses better than it’s natural sugars and forced some of those out. Either way I’m going to try this on another plant and see what happens. Is there a benefit to it? Probably not, but I’m going to get the substance tested. I’ve ingested all of the little sap pockets I’ve found and while it tastes like canna, it doesn’t seem physchoactive. Who knows, it could be loaded with CBD or something else.”

Sap globule appearing all over the buds of this cannabis plant

Stem Sap (more common) – often appears to seep out of injured parts of the stem, but not always! Sometimes sap seems to ooze out of uninjured parts of the stem.

Sap seeping from the stem of a cannabis plant is somewhat more common than seeing sap on the buds

In this last case, there’s nothing that seems to be causing the sap except possibly genetics. Here’s what HNIC_204, the grower, had to say…

This is my first grow, literally. I have a couple females, that are currently in flowering. I am growing in soil with guano and flowering ferts (Flora Nova and Cal Mag). I have not added any sugars such as molasses or sugar daddy. The temperature stays pretty consistent, such as 78 during the day and 80’s when the lights are on. The seeds are mids from VA. The plant is looking as though it is a sativa hybrid. I’ve had two plants leak the sap, which tasted like honey, but didn’t have an aftertaste. I attempted to express more of the substance to come out and it would not. Maybe the sap is something to attract males, caused by pheromones. I don’t know, but if this happened on my first grow, I think it’s an awesome phenomenon. I have asked my local grow shop, but they didn’t have a clue.

Vegetating Cannabis Plants Have an Amazing Ability to Heal

“This is a white widow a couple of weeks into flower, quite nice, but look to the bottom of the stem and you see a big ‘knuckle’.”

Knuckle has formed at the base of this cannabis plant

“This lady was snapped mid veg by accident. She was completely on her side and connected to the main stem by a few fibers and a sliver of ‘skin’. The ‘connected’ tissue was around 1mm, (around the thickness of a credit card).

“She was roughly taped upright with some very haphazard wrapping with electrical tape and forgotten about. Not only is she looking pretty good, (for a small pot and relatively modest light), she’s not at all delayed or less healthy than her sisters. I guess the message is never give up…”
