How Do I Turn My Buds Purple?

Purple weed really draws 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.

1. What’s The Difference Between Green and Purple Buds?

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.

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.

2. Are Purple Buds More Potent?

There’s no correct way to know if purple buds are more potent. In fact, purple buds 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.

Every single person is different and can react differently to the same flowers. There are probably a lot of growers that swear purple buds are 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.

3. Which Parts Of The Cannabis Plant Can Turn Purple?

Calyxes

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.

Trichomes 

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.

 

In some genetics trichomes can turn purple or even pink trichomes.

Pistils

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.

Leaves

The fan and sugar leaves of your cannabis plant can also turn purple.

 

 

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.

4. How To Make My Flowers Turn Purple?

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

Genetics

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

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.

Temperature

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.

 

Optimal temperature to turn your bud purple.
 

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.

5. In Conclusion

True purple cannabis strain 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.
