Auto CheMACal Romance Autoflowering Seeds – DNA Genetics · Fast, Potent & Easy Grow · 3 Seeds

Auto CheMACal Romance by DNA Genetics is a high-octane autoflowering powerhouse that delivers massive yields of frosty, aromatic buds in just 75 days — no experience needed.

Still stuck with slow, low-yielding plants that barely survive a light breeze? You're not alone. Most autoflowers promise big but deliver weak stems, sparse colas, and a flavor that fizzles out like cheap soda. And let’s be real — if you're investing time and space, you want more than a few sad nugs at the end. The frustration of watching your plant stretch too much, snap under its own weight, or get wiped out by mold is real. You didn’t start growing to babysit a diva.

Meet Auto CheMACal Romance — DNA Genetics’ answer to weak autos. This isn’t just another fast strain; it’s a compact, resilient machine bred for speed, power, and flavor. With a robust indica-dominant structure, it grows fast and stays strong, producing thick, trichome-coated buds in record time. No training needed, no weak genetics — just plug, play, and harvest.

Massive Yields Without the Wait

Auto CheMACal Romance turns your grow space into a high-output zone. Indoors, it delivers up to 550 g/m² (18 oz/ft²) in just 75 days from seed. Outdoors, each plant can pump out 200 g (7 oz) of dense, aromatic bud — even in short seasons. That’s not just fast; that’s efficient.

Compact Powerhouse for Any Space

With an indoor height of 80–100 cm (31.50–39.37 in) and a sturdy, bushy structure, this strain fits perfectly in tight spaces. It’s ideal for stealth grows, balconies, or small tents. Thanks to its short flowering cycle and resistance to mold and pests, it thrives in less-than-ideal climates.

Quick overview: autoflowering · DNA Genetics · 75-day cycle · low difficulty · ideal for indoor or outdoor in temperate climates.

Safe start: germinate in a moist paper towel at 22–25 °C. Transplant once the taproot is ~1 cm long. For a hassle-free start, Bio Vega speeds up rooting and reduces transplant stress.

Stable seedling: keep humidity at 60–70% and light intensity moderate. Water lightly and ensure good drainage. Add Great White Premium Mycorrhizae complex to boost root development and resilience.

Directed growth: maintain 18–20 h light, 22–26 °C, and 50–60% RH. Use LST to open up the canopy. Avoid topping. Keep substrate well-aerated — coco or light soil works best.

Efficient flowering: reduce RH to 40–50%, increase ventilation, and support heavy colas. At peak bloom, add Heavy Bud Pro Grotek to boost resin and density.

Harvest and refinement: harvest when trichomes turn milky-amber. Flush 7–10 days before. Dry at 18–22 °C and 50–60% RH, then cure for 2–4 weeks in glass jars.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of autoflowers, but Auto CheMACal Romance stood out immediately. I grew it in a 20 L pot under a 600W LED, and it stayed under 100 cm while packing on dense, resin-heavy colas. The smell during flowering was intense — lemon fuel with a spicy kick — so I used a carbon filter. The high is fast-hitting and uplifting, perfect for daytime. What I love most is how forgiving it is: no nutrient burn, no stretch panic, just consistent results. If you want a fast, potent, and reliable auto, this is your go-to. Pro tip: don’t top it — let it do its thing naturally.
