Frequently Asked Questions

How long does Auto Blue Pyramid take to grow?

Indoors, it finishes in about 60 days from seed to harvest. With high-end LED lighting, it can be ready in as little as 53 days. Outdoors, harvest time depends on climate but typically falls within 70–75 days.

What size pot should I use for Auto Blue Pyramid?

We recommend a final pot size of 18–27 L. This gives the roots enough space to develop without overwatering risks. Avoid transplanting after the first week to prevent stress.

Does Auto Blue Pyramid need a lot of nutrients?

No, it thrives on a light to moderate feeding schedule. Overfeeding is a common mistake with autoflowers—start low and increase gradually. Organic nutrients work especially well.

Can I grow Auto Blue Pyramid outdoors in a cold climate?

Absolutely. Thanks to its Ruderalis heritage, it tolerates cooler temperatures and shorter summers. Just ensure it gets plenty of direct sunlight and protect it from heavy rain to prevent mold.

Why does my Auto Blue Pyramid turn blue?

The bluish hue develops in cooler temperatures during late flowering. It’s a natural response and a sign of anthocyanin production—completely safe and visually stunning.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown a lot of autoflowers, but Auto Blue Pyramid stands out for its balance of speed, yield, and beauty. I ran it in a 60x60x160 cm tent with a 300W LED, one plant per 18L pot. I kept it simple: light soil mix, Canna nutrients, and daily LST to spread the canopy.

What surprised me was how fast it moved—flowering started around day 21, and by day 55, the trichomes were milky-amber. The buds were dense, covered in resin, and had that gorgeous blue tint. The high is deeply relaxing, perfect for unwinding after a long day. My only tip? Don’t top it—just train it gently. This strain rewards simplicity with quality.
