Purple Pot Plants – A Few Dos and Don’ts

Purple Pot Plants – A Few Dos and Don’ts

By Grow How

One guaranteed way of gaining the attention of any seasoned smoker is to tell them you have purple weed growing at home. Just the very mention of purple pot instantly brings to mind the thought of not only super-intense bud, but also one of the most beautiful plants imaginable. Even looking at the stuff is a treat, but what exactly is it that makes certain pot become purple? Can you buy pot seeds in the United States specifically for the purposes of growing purple pot? Or can you grow standard green weed and actively turn it purple? 

 

Well, if you’ve ever wondered why some pot plants turn purple, here’s a very brief explanation of the science behind that.  First of all, every type of marijuana initially starts out as a purple plant, but soon turns green as chlorophyll takes over and the photosynthesis process intensifies. However, there are certain marijuana strains which upon reaching the end of their life cycle, their chlorophyll reserves die off and once again give way to the purple.


Purple Plant Pimping

 

So, does this technically mean that it is possible to turn all marijuana plants purple? In a word, yes. That is however, just as long as you buy pot seeds in the first place that are right for job. What this means is selecting seeds that have a high concentration of anthocyanin – the same pigment that gives blueberries and eggplant their vibrant colour. Just a few examples include Northern Light Automatic, Haze Berry, Blue Mystic and plenty of others. These are the kinds of plants that will often yield extremely pretty purple coloration in their own right, but there’s also room for nurturing things in the right direction.

 

Quite simply, the easiest way of encouraging the purple coloration to really take over is to slightly reduce the temperature of your growing environment during the dark cycle. The reason being that chlorophyll and its green pigments are broken down quickly and more intensively when the temperature is cooler. And this is precisely why many of the most famous and celebrated purple strains of marijuana tend to be those that originate from northern regions where the evenings are cooler.

 

Specifically, you should be looking to reduce the temperature below the 17° C mark during the dark cycle for around 14 days before you plan to go about your harvest. If you time it right, chances are you will be rewarded with beautiful purple buds and leaves.


What Not To Do


As is the case with all weed matters, you’ll no doubt come across a whole world of conflicting information and advice with regard to plant purpling.  Nevertheless, you should really only ever listen to the experts who have tried and tested every trick in the book, in order to prevent you from making one of many potentially fatal mistakes.

 

For example, some suggest that effectively forcing the plant to hold its breath can assist in the purpling process. This basically means depriving the plant of nitrogen, carbon dioxide or oxygen. In truth, this approach simply does not work in any way, shape or form and will only stand to inhibit the growth and yield of your plants. Not only this, but to reduce nitrogen will almost certainly result in leaf burn due to nutrient deficiency.

 

As for the shortcut method of adding purple dye or food coloring to the plant, you’ll certainly end up with a pretty purple colour in the immediate moment, though perhaps at the cost of your plant’s life. Literally – it could kill the whole thing dead!
