Fat Banana Auto by Royal Queen Seeds is a powerhouse indica-dominant autoflower that delivers dense, aromatic buds and a relaxing high in record time—perfect for growers who want quality without the wait.

Still juggling five different strains, three nutrient lines, and a grow journal longer than a Tolstoy novel just to get decent buds? What if you could cut the clutter and still crush your harvest goals?

Too many growers overcomplicate their setup, thinking more gear and more strains mean better results. But the truth? It often leads to confusion, wasted time, and inconsistent yields. You end up babysitting plants instead of enjoying the process.

Fat Banana Auto cuts through the noise. This single strain delivers massive yields, top-shelf flavor, and knockout potency—all in a compact, no-fuss package. No need to rotate photoperiods or stress over light cycles. Just plant, feed, and harvest in under 10 weeks.

Less Gear, More Results

Fat Banana Auto isn’t just another autoflower—it’s a full harvest solution. With its robust genetics and fast cycle, it replaces the need for multiple experimental strains or backup plants. You don’t need a separate “fast finisher” or “flavor pop” because this one does it all: high THC, tropical terps, and up to 450g/m² indoors.

Its compact size and resilience mean you can ditch the complex climate control rigs. It thrives in simple setups, making it ideal for stealth grows or small tents. Pair it with a basic autoflowering seeds nutrient line and you’ve got a complete, low-maintenance system.

Quick overview: Autoflowering · Royal Queen Seeds · 9–10 week cycle · Medium difficulty · Ideal for indoor tents or outdoor patios.

Safe start: Germinate in a moist paper towel or starter cube. Transplant gently once the taproot is ~1 cm long. For faster rooting and less shock, Clon Fix strengthens young roots from day one.

Stable seedling: Keep humidity at 60–70% and temperature at 22–25 °C. Use a well-aerated soil mix. Water lightly and avoid nutrients for the first week.

Directed growth: Maintain 18–20h light. Apply light LST early to open up the canopy. Feed with a balanced grow formula—Connoisseur Grow A+B Ph Perfect keeps pH stable and prevents nutrient lockout.

Efficient flowering: RH 40–50%, temps 20–25 °C. Support heavy colas with stakes. Add HESI Phosphorus Plus at week 3 of flower for bigger, denser buds.

Harvest and refinement: Harvest when 70% of trichomes are milky with amber hints. Flush 7–10 days before cut. Dry at 18–21 °C and 50–60% RH, then cure for 3–4 weeks in jars.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve tested dozens of autoflowers over the years, but Fat Banana Auto stands out. Last season, I grew it alongside three photoperiods in my 1.20 x 1.20 m tent. While the others were still in veg, Fat Banana was already in mid-flower—no light changes, no stress.

I used a simple 20 L fabric pot, organic soil, and minimal LST. At week 8, the buds were already massive, sticky, and smelled like a fruit market. I harvested at day 65, dried slowly, and cured for four weeks. The high is deep and calming—perfect after a long day. It’s now a permanent part of my rotation. If you want quality without complexity, this is your strain.
