Sweet Pure Auto CBD® – Sweet Seeds 6th Gen Autoflowering CBD Strain with 8-20% CBD, Low THC <1%

Sweet Pure Auto CBD® is a 6th generation autoflowering cannabis strain from Sweet Seeds, delivering high CBD levels of 8–20% and minimal THC (0.4–0.9%), making it ideal for therapeutic use without psychoactive effects.

Do you want the benefits of CBD without the high?

Many people turn to cannabis for relief, but not everyone wants the mental fog or racing heart that can come with THC. If you're looking for calm, clarity, and comfort without the buzz, traditional high-THC strains just don’t cut it.

What happens when your medicine doesn’t work—or worse, makes you feel worse?

You end up frustrated, stuck in a cycle of trial and error. Maybe you’ve tried CBD oils that wear off too fast, or edibles with inconsistent results. Or worse—smoking strains that leave you anxious or drowsy when you just wanted to relax. The search becomes exhausting, and your trust in natural solutions starts to fade.

Sweet Pure Auto CBD® gives you pure, reliable CBD relief—fast, easy, and without compromise

This is the first autoflowering strain from Sweet Seeds specifically bred for maximum CBD and minimal THC, with a ratio as high as 1:23 (CBD:THC). In just 8 weeks from seed to harvest, you’ll have a steady supply of non-psychoactive, sweet-tasting flower perfect for daytime use, stress relief, or blending with other strains to smooth out the high.

Fast, reliable harvest with maximum CBD and minimal effort

With Sweet Pure Auto CBD®, you skip the guesswork. It’s a low-maintenance autoflower that thrives in small spaces and delivers consistent results. Whether you're growing indoors under LED or outdoors in a sunny spot, this strain adapts easily and finishes fast—no long waits, no complicated light cycles.

Simple steps to grow your own CBD medicine in under 2 months

1. Germinate seeds in a moist paper towel or directly in a light, airy soil mix.
2. Place under 18–20 hours of light daily—no need to change the photoperiod.
3. Transplant to a 18–27 L pot early to avoid root stress.
4. Water when the top inch of soil feels dry—don’t overwater.
5. Harvest after 8 weeks when trichomes turn milky to amber.

Grow smarter: tips to maximize your CBD yield without stress

Start with a well-aerated soil mix and avoid heavy fertilizers—this strain prefers a light feeding schedule. Use a root stimulator like Clon Fix during germination to boost early development. In flowering, support side branches gently if needed, but avoid pruning—autoflowers don’t recover well. For best flavor and effect, flush with plain water 7–10 days before harvest.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of CBD strains, but Sweet Pure Auto CBD® stands out for its reliability and clean effect. I planted four seeds on my balcony in mid-spring—no greenhouse, no fancy gear. Just 200W LED, 18/24 light, and a 20L pot each. All germinated, and within 8 weeks, I had dense, trichome-covered buds with a lemon-cypress aroma that filled the room.

What I love most is how it makes me feel: grounded, focused, and relaxed—no drowsiness, no brain fog. I use it daily to unwind after work or to ease tension without losing productivity. I even mixed it with a high-THC strain once, and it smoothed out the high perfectly. If you want a no-fuss, high-CBD autoflower that delivers every time, this is your plant.
