growing purple weed

Lower temperatures may help the plant turn purple but it may also likely slow plant growth, it’s generally not recommended for growers to lower down the temperature just to achieve colored buds, especially at the beginning of the flowering stage where you may actually be doing more harm than good.

The fan and sugar leaves of your cannabis plant can also turn purple. Cannabis leaves can turn completely purple, but sometimes they only exhibit a purple coloration around the veins or the tips of the fingers.

These plants have been genetically selected to produce anthocyanin rather than chlorophyll and will grow purple on their own, you don’t have to do anything special to them.

Trichomes are the tiny glands that cover your buds. Even though they usually start clear, then cloudy, and later on become amber, it is possible to find genetics with purple or even pink trichomes.

There’s no correct way to know if purple weed is more potent. In fact, purple weed can be more potent than green buds or vice-versa. But have in mind that color has nothing to do with it, it’s all about genetics. If you’re a fan of purple strains, our LSD-25 with THC levels above 21% is just the right option.

Bright Light.

There are a couple of plant species that are known to exhibit different colors based on the substrate’s pH. Even though it’s not confirmed, growers have noticed that different cannabis strains can exhibit slightly different colors on the leaves and buds depending on the pH levels. For example, purple strains tend to turn even more purple if the pH is below 6.0 but most strains will show signs of deficiency when the pH is below 6.0 so it’s not recommended to use this method if you’re a beginner.

However, most plants have functional pigments other than chlorophyll and in the absence of chlorophyll, many plants will use anthocyanin or carotenoids (other pigments) to capture sunlight energy. Unlike chlorophyll, anthocyanin absorbs all wavelengths except for those in the indigo/violet spectrum, this makes it reflect back violet light , making the plant look purple to the human eye.

Just remember that purple weed or purple weed strains are not stronger than green buds because cannabinoid production does not depend on bud color. Purple cannabis buds are definitely beautiful but are basically the same as green buds, both buds contain cannabinoids, terpenes, flavonoids, and everything else; Obviously, there are differences between purple weed strains and green ones just like the differences you’ll find when growing different strains, but at the end of the day, purple weed is the same it just looks better. If you still want to grow your purple weed, remember that the main elements that affect bud color are:

In most cases, when the substrate’s pH is below 6.0, the purple, red or blue colors get even deeper but it’s most likely that most of the leaves get deficiencies so if you’re a beginner and want to try this, make sure you do it close to harvest so you can harvest your plant if something goes wrong.

There are only two ways to correctly make your buds change color: genetics and temperature.

Some strains will grow purple all on their own. If you are looking to grow purple weed strains you’ll get the best results by finding purple genetics like our Purple Lemonade .

Calyxes (the bud itself) are the small pods that make up your buds. Cannabis flowers are actually made up of hundreds of these small calyxes stacked on top of one another. Even if not all the calyxes change color, there are cases where some stay green, and others turn purple, resulting in a multi-colored bud.

E very single person is different and can react differently to the same flowers. There are probably a lot of growers that swear purple weed is more potent. The truth is purple light contains the highest energy on the visible spectrum. So based on this we can assume purple bud can’t be more potent than green bud since purple flowers are reflecting and not absorbing the spectrum that produces the most energy.

In case you’ve never seen a purple cannabis plant before, make sure to check our Purple Punch Auto strain review video below. Now that you have a better idea of what purple weed or a purple weed strain is, you’ll get a better understanding of this article, so read along!

In most plants (including cannabis), the dominant pigment is chlorophyll. Chlorophyll is extremely efficient at capturing light energy because it can absorb nearly every wavelength of the visible light spectrum. In fact, the only wavelength it does not absorb and reflects is those in the “green” spectrum, that’s the reason why most plants appear green to the human eye.


True purple weed strains will turn purple no matter what you do in the environment, this lowers significantly the harm you can cause by lowering temperatures and will guarantee a 100% healthy purple plant, leaving you and your plant happy. In case you need help choosing purple genetics for your next grow cycle, here are more purple autoflowering strains that you may like.

In some cases, especially with LED fixtures, strong lights can help bring out different colors on cannabis plants. This happens because strong, direct light can end up destroying chlorophyll cells , thus promoting different tones such as red, pink, and purple. But, when this happens, the colors are more apparent on the parts of the cannabis plant that are getting the stronger light, so the rest will most likely stay green. When growing under HPS lights, this is uncommon but can also happen when growing under 400 W or higher wattage HPS bulbs, although growers mention that the colors are not as bright as when growing under LEDs.

Purple weed buds really draw attention. It’s hard to believe but there are a lot of cannabis growers out there that will tell their customer’s purple weed is better or more potent than a standard green bud and this is completely wrong.

Pistils are the fine hairs that pop out of your buds, letting you know they’re female. Pistils generally start a white color and turn orange/red/brown as plants mature. It is possible for your plant’s pistils to turn pink or purple, and this color will remain after you harvest, dry, and cure your buds.

It seems like having a cooler night period can encourage cannabis plants to display red, pink, or purple colors. This does not work with all strains and while trying to change colors with low temperatures you may sometimes shock your plants , resulting in smaller yields. You can go as low as 13C (55F) with most strains and it shouldn’t be a problem, but remember you can cause permanent damage for some cold-sensitive strains.

However, they usually won’t have a big effect on the final color of your buds. So you can trim away most of the leaves after or before drying.

So make sure to take all of these into consideration and experiment on your next grow cycle if you want to harvest some beautiful purple marijuana buds.

4. How To Make My Flowers Turn Purple?

In this guide, we provide you with a concise guide to growing purple cannabis. This includes the right and wrong ways to proceed. First, let’s look into the factors that determine a marijuana strain’s color.

However, plants use an assortment of other pigments to turn sunlight into energy. These include anthocyanins which absorb all wavelengths from the sun except colors in the indigo spectrum. This is what gives plants a purple tint. Therefore, purple plants have anthocyanins as the dominant pigment instead of chlorophyll.

In addition, you should only decrease the night time temperature by a maximum of 15 degrees Fahrenheit. Some growers believe that plunging it 30+ degrees will lead to purple cannabis. What’s more likely is that your plants go into shock. At best, your crop’s growth is stunted. The worst-case scenario is dead plants!

What Parts of the Cannabis Plant Change Color?

Yet another unhelpful method is to reduce phosphorus intake. Messing around with nutrients will only lead to trouble.

Remember that your buds will lose color after trimming, so take this into account.

Otherwise, there is little more to it! Pick the right genetics and play around with slightly lower nighttime temperatures. You could also try the lighting tip but approach with caution. Also, it is best to grow the weed indoors as it is easier to control conditions.

The genetics of a strain has the most significant impact on the final color. If you pick cannabis that doesn’t have a propensity to turn purple, you are wasting your time. Genetics also plays a considerable role in THC or CBD content and flavor. Here are a few good options to consider:

The purple color is all about the anthocyanin content of the strain. Without it, you can’t expect to enjoy the gorgeous purple weed you crave.

Another is that adding extra nitrogen to the soil will help your plants turn a deeper shade of purple. This process could lead to a color change. Unfortunately, it relates to the sickly yellow hue associated with a nutrient burn!

3 Steps to Growing Purple Cannabis.

A good tip is to look for intense purple buds as these provide maximum color after the drying and curing process. These deeply colored strains are sometimes called ‘black’ strains and are more vibrant when dried and cured. Once again, it is best if the color goes through the buds.

The complete comparison…

Ultimately, there is no magic formula that turns weed purple. It all depends on a plant’s genetics. Don’t purchase Green Crack, Green Door Kush, or Green Dream in the hope you can turn it purple. Instead, focus on the following:

You also need to pick a strain where as many parts of the plant as possible are colorful. Ideally, the plant will have pistils and calyxes with a purple color.

What to Avoid When Growing Purple Cannabis.

However, certain strains don’t react to this tactic. Some, like Panama, change color regardless of the temperature because of its genetics. Querkle, on the other hand, is more likely to show its color with warmer days and standard night temperatures.

Here are the four main parts that offer colors apart from green:

Finally, please avoid adding artificial dye! The color of the harvest is genetically encoded. Marijuana strains that are not predisposed to turning purple won’t. The only thing you’ll achieve by adding purple dye to the buds is the potential increased consumption of toxins.

There are ways to boost the purple coloring on your marijuana. However, without the right genetics, you have no chance of succeeding.

There are several myths and falsehoods attributed to cultivating purple marijuana. While some are silly, others are downright dangerous to your plant. One such suggestion is that you should deprive your plants of CO2 or oxygen.

What Exactly Is Purple Cannabis?

Purple cannabis is a type of cannabis that has deep purple flowers and leaves. Like all other strains of cannabis, this also starts with green leaves that change color when exposed to cold temperatures. The strain of cannabis might sound new, but it has been around for a long time now.

You now know the steps to grow beautiful and potent purple cannabis. With so many myths about growing these strains, it’s also crucial to differentiate the facts from misconceptions.

How Not to Grow Purple Cannabis.

To produce the most colorful results, you have to make sure that the color reaches the buds and the leaves surrounding it. Buds that are pale in color from the start usually lose most of that vibrancy upon reaching maturity. So, go for the darkest purple strain of cannabis that you can find.

There is no denying that finally getting to harvest the plant is the best part of the entire process. But, figuring out the right time for harvesting is something that needs a bit of keen observation. The plant will start growing buds as the first sign of being ready for harvest. Get your magnifying glass out, and look closely at the plant to know if it’s ready.

The Process of Growing Purple Cannabis.


Now, take the buds and hang them out to dry for six weeks at a minimum. Your purple cannabis is ready!

You need to select pistils, calyxes, and buds that are brightly colored from the start so that the result is as colorful. For getting the best effect on the cured and dried buds, you need to go for a strain where most parts of the plant are colorful. Apart from the buds and pistils, it’s even better if the trichomes and leaves are colorful, as well.

Choose the seeds that contain more anthocyanins to get the purple color from the beginning. If you choose a cannabis strain containing more catenoids, the plant will be yellow instead of purple.

First off, no amount of carbon dioxide or oxygen deprivation can turn a green cannabis plant into a purple one. Therefore, let the plants breathe and don’t unnecessarily suffocate them. The same thing goes for adjusting the plants’ water and light: that’s not how you turn the plant purple. Even increasing nitrogen will only make the plant turn brown.

To understand the reason behind this unique colorization, you’ll have to know about flavonoids and hybrid weed . These plants are rich in flavonoids, which determine if a plant will turn orange or purple. And anthocyanin is the flavonoids from which cannabis gets its color. Otherwise, purple cannabis has cannabinoids, THC, and terpenes, just like all other strains.

Purple cannabis needs the right kind of temperature to get a vivid shade. Anthocyanin production and cold temperature are closely related. As such, anthocyanin gets activated by shorter, cooler days and longer, colder nights.

Since you must be having so many questions about growing purple cannabis, here’s an easy guide to solve all your doubts.

On looking at the buds and leaves under a magnifying glass, you’ll notice that small crystal-like substances have started coming out of them. These are trichomes, which will go from being clear to cloudy in appearance within a few days. And, you can harvest the plant when all the trichomes turn cloudy.

Now that you got a thorough idea about what purple cannabis is, let’s get to the process of growing the plant. Keep the following things in mind when growing this plant:

In this regard, it’s important to mention that certain purple cannabis strains work well under direct, strong light. You can ask the breeder about any specific advice they might have regarding the strain that you have purchased to grow.
