MK Ultra TH Seeds Feminized – Powerful Indica Hybrid with Hypnotic Effects · G-13 x OG Kush Genetics

MK Ultra TH Seeds feminized is a knockout indica hybrid that merges G-13’s potency with OG Kush’s legendary resin production, delivering a deeply relaxing, hypnotic experience in record time.

Are you still rolling with strains that barely put a dent in your stress? Ones that smell average, taste flat, and leave you wanting more after two hits?

Weak genetics mean weak results—skunky aftertastes, airy buds, and effects that fizzle out before you even unwind. You end up wasting herb, time, and good vibes just trying to chill.

MK Ultra changes that. Born from two titans—G-13 and OG Kush—this feminized powerhouse packs dense, trichome-bombed buds that reek of pine and citrus, with a high so smooth and heavy it’ll pull you into the couch like a velvet trap. It won 1st place at the 2003 Cannabis Cup for a reason: this isn’t just smoke, it’s a sensory reset.

What Makes MK Ultra a Grower’s Dream

From first sprout to final cure, MK Ultra stands out with vigor, resilience, and a nose that fills the room. It’s not picky, doesn’t demand lab-level precision, and still outperforms finicky strains. Whether you're in a closet or a greenhouse, it adapts fast and rewards generously.

• Because it’s feminized, you get only bud-producing plants—no surprises, no wasted space
• Thanks to its 8–9 week flowering time, you harvest faster than most indicas and avoid mold season outdoors
• With 350 g/m² indoors (12.35 oz/ft²), you get serious yield without stretching your lights or budget
• Its 100–120 cm height (3.28–3.94 ft) makes it perfect for stealth grows and SOG setups
• The high THC content delivers a euphoric, sleepy, and deeply relaxing effect—ideal for unwinding or drifting off

How to Grow MK Ultra for Maximum Resin

This strain thrives on simplicity. Start strong, keep conditions stable, and let its genetics do the work.

• Germinate seeds in a moist paper towel or directly in starter cubes at 22–25 °C
• Transplant to final pots early—18–27 L (4.75–7.13 gal) for autos, 11–20 L (2.90–5.28 gal) for photoperiods
• Use well-aerated soil or coco; consider adding Alg-A-Mic BioBizz to boost root development and terpene production
• Provide 18/6 light cycle in veg, switch to 12/12 to flower; maintain temps at 22–26 °C in veg, 20–25 °C in flower
• Add HESI Phosphorus Plus in mid-flowering to fuel bud density and resin
• Monitor trichomes: harvest when mostly milky with some amber for a balanced, sleepy high

Frequently Asked Questions

Is MK Ultra good for beginners?

Absolutely. It’s forgiving, grows fast, and doesn’t need advanced techniques to shine. Just keep humidity under control in flowering and you’ll be golden.

Does MK Ultra smell strong during grow?

Yes, it has a pungent pine-citrus aroma. If discretion is key, use a carbon filter like those in grow room air purifiers to keep things low-key.

Can I grow MK Ultra outdoors in a cold climate?

It handles temperate climates well and finishes by October in the Northern Hemisphere. Just make sure your season is long enough—8–9 weeks from flower to harvest.

What’s the best way to use MK Ultra?

Best enjoyed in the evening. It’s not a daytime strain—this one’s for deep relaxation, stress relief, and a solid night’s sleep.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown MK Ultra three times now, and it’s become my go-to for stress relief. The first time, I ran it in a 1.2 m² tent with a 600W LED. I used LST early to spread the canopy, and by week 5, the smell was already unmistakable—sharp pine with a diesel kick. I added Super Vit in the first two weeks of flowering, and the bud density was insane. Harvested at 60 days, got 380 g/m², and the cure took two weeks. The high? Immediate, heavy, and warm—like a weighted blanket for the mind. No anxiety, no paranoia. Just peace. If I could only keep one strain in my vault, this would be it.
