Did you know that many roses that have extremely vibrant colours aren’t naturally that colour? No. They put dye in the water and the petals, that would originally have been white, or red, absorb the dye in the water.

However, you don’t have to use purple dye in the water for your cannabis plants as you can actually buy plants that produce purple cannabis – more on that later

But first lets explode a few more myths.

Depriving your plants of oxygen, or any other gases for that matter, won’t turn them purple, but will be more likely to kill them.

Feeding your plant excess nitrogen won’t make them turn purple either, though it will likely change their colour to brown as they die and wither after getting burnt to a crisp.

You could try purple dye, but we don’t recommend it. If you do go down that route for fun, get a natural food colouring, not a chemical dye, as you are going to be igniting and inhaling the dye at the end of the day.

As for which parts of your plant will turn purple, this can be the pistils, the calyxes, the leaves and the trichomes.

Having chosen the right plants, there are still a few things you need to keep an eye on.
First, once they have ended vegetative growth and are ready to start flowering, drop the night-time temperature by 10-15 degrees compared to the daytime temperature.

This will help break down the chlorophyll and encourage the production of more anthocyanins.

When it comes to naturally purple plants, keep an eye out for Purplematic CBD ,Purple Queen, purple punch, granddaddy purple etc – the names should give you a clue.

Purplematic is high in cannabidiol and very low in THC, with deep, rich purple buds.

Purple Queen is virtually a pure Indica and a combination of Hindu Kush and Purple Afghani genetics. Flowers after roughly 10 weeks and has a high 22% THC content.

Blue Mystic is a cross between Oregon Blueberry and Northern light, resulting in an 18% THC level and rich, purple buds.

I wonder how Purple Ronnie got his name…
