For Beginners: Why AMG Is Your Gateway to Premium Cannabis

Don’t let the awards and high THC scare you off—AMG is surprisingly beginner-friendly. It’s forgiving during veg, responds well to basic training, and doesn’t demand lab-level precision.

Frequently Asked Questions

Is AMG good for beginners?

Yes. While it’s a sativa-dominant strain with high THC, AMG is stable, resistant, and forgiving of minor mistakes—perfect for growers stepping up from beginner strains.

How tall does AMG get outdoors?

Up to 2 m (6.56 ft). It’s a tall, vigorous grower, so ensure it has space and support, especially in windy areas.

Does AMG smell strong during flowering?

Yes, it has a medium to high odor. Use a carbon filter or grow in a well-ventilated area to maintain discretion.

Can I grow AMG in a Sea of Green (SOG)?

Yes, but it’s better suited to SCROG or single-plant grows due to its height and stretch. SOG works best with smaller, bushier strains.

What’s the best time to harvest AMG outdoors?

Mid-October in the Northern Hemisphere. Watch for trichome maturity—milky trichomes give a more cerebral high, while amber tones add body relaxation.

Personal Experience of Pevgrow’s CEO (Alan)

I first grew AMG when I was tired of sativas that promised euphoria but delivered anxiety. This one? It’s different. The high hits fast—like a wave of mental clarity and joy—and lasts for hours without the jitters. I’ve shared it with friends who usually avoid high-THC strains, and even they come back asking for seeds.

From a grow perspective, it’s a joy. I ran it in a 120x120x200 cm tent with a 600W HPS. I topped each plant twice and used SCROG—yield was 480 g (16.93 oz) across three plants. The smell during flowering was intense—citrus and spice filling the room—so I had to run a carbon filter. Buds were dense, frosty, and cured into a smooth, flavorful smoke.

For new growers, I’d say: don’t fear the sativa. AMG is powerful but balanced. For experts? It’s a canvas. Push the nutrients, train the hell out of it, and you’ll be rewarded. It’s not the fastest, but it’s one of the most satisfying grows I’ve ever done.
