Purplematic CBD by Royal Queen Seeds – High-CBD Autoflowering Strain with 17% CBD · Fast 8–9 Week Harvest

Purplematic CBD by Royal Queen Seeds is a high-CBD autoflowering strain delivering 17% CBD and less than 0.5% THC, making it perfect for clear-headed, non-intoxicating use throughout the day.

Are you tired of CBD strains that barely pack a punch?

Most CBD-rich varieties offer modest cannabinoid levels and take forever to mature. You end up waiting weeks for underwhelming results—low resin, faint aroma, and buds that don’t live up to the hype.

What if you could grow a CBD strain that actually stands out?

Imagine a plant so visually striking it becomes the centerpiece of your grow room—deep purple calyxes, fiery orange pistils, and a thick coat of glistening trichomes. Now imagine it finishing in under 9 weeks, with lab-verified 17% CBD and barely detectable THC. That’s not a dream. That’s Purplematic CBD.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Purplematic CBD in my 1.2 m² tent with 600W LED and 12 plants in 7L pots. From seed to harvest: 62 days. What blew me away was the color—deep violet calyxes with orange flames and a frosty trichome layer that sparkled under the light. The smell? Earthy pine with a hint of ripe berries. I didn’t touch it with any training, and it yielded 432 g/m². I vaped it daily for focus and post-work relaxation—zero brain fog, just calm clarity. If you want a no-fuss, high-CBD strain that delivers on every level, this is it.
