About Caffeine

Caffeine is a sativa-dominant hybrid crossed from ESPRESSO x NORTHERN LIGHTS that delivers an energetic, clear-headed high. Its flavour blends roasted coffee and citrus on an earthy base, and it suits growers seeking a daytime variety with pronounced aroma.

Grow Difficulty:

Caffeine presents a moderate challenge under humid indoor grow rooms because it shows sensitivity to excess moisture. Outcomes improve where environmental consistency is maintained.

Flowering Time:

Indoor flowering commonly completes within eight to nine weeks. Outdoor plants in Kent generally finish later in the season when conditions are cooler.

Yield:

Yield potential is medium to high with stable conditions and careful selection of phenotype. Results vary with growing environment and plant management choices.

Height:

Plants display a lanky, open structure with long colas and moderate branching. Indoor heights usually sit between eighty and one hundred and forty centimetres, while outdoor specimens can grow taller.

Environment:

Indoors Caffeine performs well in controlled environments in Kent where conditions are stable. Outdoors in Kent it reaches its best expression in sheltered, temperate sites that allow a full finish.

Climate:

Growing Caffeine in Kent with humid indoor grow rooms emphasises the importance of monitoring environmental variables. In Kent that environment requires attention to moisture to preserve trichome and terpene character.
