CBD Chronic Feminized Seeds – Serious Seeds' High-Yield 1:1 THC:CBD Strain for Easy Medical Growing

CBD Chronic feminized seeds by Serious Seeds deliver a powerful 1:1 THC:CBD ratio, massive yields up to 700 g/m², and effortless growth — making them a top choice for medical users and home cultivators who want reliable, high-CBD medicine without compromising on potency or production.

Struggling to find a strain that actually delivers balanced cannabinoids without weak effects or finicky growing needs? You’re not alone. Many growers waste time on seeds that promise medical benefits but fail in yield, consistency, or ease of care. And if you're using cannabis for wellness, inconsistent ratios mean unreliable results — which defeats the purpose.

That frustration grows when you realize you're stuck with low-resin plants, confusing lab reports, or strains that knock you out instead of calming you down. You need something that works — not just in theory, but in your grow room, your vaporizer, and your daily routine. The status quo? Endless trial and error, wasted space, and underperforming harvests.

The solution? CBD Chronic. This isn’t just another CBD strain — it’s a lab-verified, high-yielding powerhouse born from crossing Serious Seeds’ biggest yielder, Chronic, with Remedy, a legendary high-CBD cultivar. The result? A stable 1:1 THC:CBD profile averaging 5.4% THC and 5.8% CBD, with some plants hitting up to 7.88% THC and 6.93% CBD. It’s designed for real people with real needs: consistent relief, serious resin, and harvests you can count on — all in a plant that’s easy to grow, clone, and maximize.

Stages and monitoring of CBD Chronic

Quick overview: feminized photoperiod strain · Serious Seeds · 9-week flowering · ideal for indoor or outdoor in temperate zones.

Safe start: germinate in a moist, dark environment at 22–25 °C. Transplant gently when the taproot reaches ~1 cm. For a stronger start, SeedBooster Plus germination stimulator boosts root development and reduces shock.

Stable seedling: keep humidity at 60–70% and provide gentle light. Water lightly and ensure good drainage. Introduce Cancerbero Mycorrhizae early to strengthen root resilience and nutrient uptake.

Directed growth: switch to 18/6 light cycle after 3–4 weeks. Use airy soil or coco; avoid overfeeding. Train with LST to expose lower nodes, but skip topping — this strain focuses energy on the main cola.

Efficient flowering: maintain 40–50% RH and 20–25 °C. Support the massive top cola if needed. In mid-flower, ROX Flower Enhancer increases bud density and resin production.

Harvest and refinement: harvest when trichomes turn milky to amber for a balanced effect. Flush 7–10 days before cut. Dry at 18–22 °C and 50–60% RH, then cure for 2–4 weeks to enhance flavor and smoothness.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve recommended CBD Chronic to friends who are new to growing — and every single one came back amazed. Not because it’s flashy, but because it works. It’s the kind of strain that builds confidence. You plant it, it grows strong, and you end up with sticky, fragrant buds that actually do what they’re supposed to. For beginners, that’s gold.

But I also use it myself — not just for the balanced effect, but because it’s so damn efficient. I run a small SCROG setup, and the huge main cola fills the screen perfectly. I’ve extracted oil from it, vaped it, and even made a salve for my dad’s arthritis — all from the same harvest. The flavor’s smooth, the high is clear, and the resin? Off the charts. It’s rare to find a medical strain that’s this productive and this reliable. This one’s a keeper.
