About Alien Pebbles

Alien Pebbles is a compact indica-dominant hybrid bred from Alien OG x Pebbles. It produces dense, citrus-kissed buds with sweet and earthy notes. Flowering finishes in 8-10 weeks indoors and late September to October outdoors in much of England and Wales. You will see medium-high yields with steady feeding and good humidity control. Effects lean toward a relaxing body sedation with a gentle cerebral lift, so many growers use it for evening sessions. The seeds are feminized to give predictable female runs for small tents and glasshouses from London flats to Scottish glasshouses.

Grow Difficulty:

Difficulty rates as intermediate for most growers. You should focus on humidity control in UK setups, especially in greenhouses during summer.

Flowering Time:

Indoor flowering runs 8-10 weeks. Outdoors it finishes late September to October across much of England and Wales.

Yield:

Yield is medium-high with dense, resinous buds. Indoor growers in Manchester and Bristol report 400-450 g/m² under steady conditions.

Height:

Plants stay compact to medium, reaching 60-120 cm. That height suits small indoor rooms and greenhouse benches common in Cornwall.

Environment:

Suitable for indoor, greenhouse and sheltered outdoor sites. Damp British weather makes glasshouses a smart choice in Scotland and Yorkshire.

Climate:

Best in a mild maritime climate with humid summers and cool autumns. Grow it in Cornwall for a long season or under glass in the Scottish Highlands for protection.

How should I train Alien Pebbles for a small tent?
A

Topping once or twice in veg and gentle LST gives a flat canopy. That approach maximises light use and evens bud sites.

Flush one to two weeks before harvest to sharpen flavours. Base timing on trichome maturity rather than the calendar.
