How to grow Red Mimosa XL Auto in 5 simple steps

1. Start with a final pot of 18–27 L (6.3–9.5 gal) to avoid transplant stress—ideal for autoflowering strains.
2. Keep light at 18–20 hours daily; no need to change photoperiod—this auto flowers on its own.
3. Use well-aerated soil or coco; consider adding Trikologic (Bioponic Mix) for stronger roots and better nutrient uptake.
4. Water moderately—let the top inch dry between waterings—and avoid aggressive pruning, topping, or FIM.
5. Harvest at 8 weeks when trichomes are mostly milky with some amber for a balanced effect.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested a lot of autoflowers, but Red Mimosa XL Auto stood out from day one. I grew four plants in 20L pots under a 600W LED, 18/6 lighting, and they stayed compact but exploded in flowering. The smell? Sweet orange and pepper—friends kept asking what I was growing. At week 8, the trichomes were milky with a touch of amber, and the high was exactly what I wanted: mentally clear, creatively charged, but physically relaxed. I didn’t need to top or prune—just trained gently with LST. And the color? Two of the four turned deep purple. If you want a fast, beautiful, and flavorful strain that actually delivers, this is it.

I paired it with Grow Ph Perfect Advanced Nutrients and flushed with Flawless Finish—cleaner taste, no harshness. For a strain this vibrant and potent, it’s surprisingly easy. This one’s going in my regular rotation.
