Red Pure Auto CBD by Sweet Seeds – High-CBD Autoflowering Strain with Red Flowers & Relaxing Effects

Red Pure Auto CBD by Sweet Seeds is a high-CBD autoflowering strain with red flowers, 15–17% CBD and just 0.4–0.5% THC, delivering deep relaxation without any psychoactive buzz — perfect for therapeutic use and calm, clear-headed moments.

Struggling with stress but don’t want to get high?

Maybe you’ve tried cannabis before but didn’t like the foggy head or racing thoughts. Or perhaps you need relief during the day but can’t afford to feel impaired. For many, traditional high-THC strains just don’t fit into a focused, functional lifestyle.

What if your weed actually calmed your mind instead of clouding it?

Imagine unwinding after work with a smooth, flavorful smoke that eases tension without knocking you out or altering your perception. No paranoia, no couch-lock — just pure, gentle relaxation. That’s the reality with Red Pure Auto CBD, a strain specifically bred for balance, clarity and comfort.

Tips for maximizing your Red Pure Auto CBD harvest

Start with a high-quality soil mix rich in organic matter — adding Leaf Coat / Spray BioBizz can boost resin production and protect against humidity. Use a carbon filter if growing indoors to keep scents under control. For even better root development, consider Plagron Power Roots Root Stimulator during the first two weeks. Avoid topping or aggressive pruning — let the plant focus on flowering from day one.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of CBD strains, but Red Pure Auto CBD stands out. I used it during a high-stress work period and found it helped me unwind without dulling my focus. I grew four plants in 20L pots under a 400W HPS, and all turned a deep red — absolutely stunning. They stayed under 80 cm (31.50 in), perfect for my closet setup. Even with minor nutrient imbalances, they bounced back fast. The flavor is smooth, with a sweet berry-pine punch. I especially love it in the evening — it clears mental chatter and sets the mood for deep sleep. If you want reliable, high-CBD medicine with zero high, this is your strain.
