Pineapple Express

Environment

Aim for temperatures in the 22–26 °C (72–79 °F) range during lights-on, dropping a few degrees lights-off. Relative humidity is best kept around 50–60% in veg, stepping down toward 40–50% in early flower, and ideally below 45% in the final weeks of ripening. Consistent airflow through and under the canopy is important — Pineapple Express tends to produce moderately dense buds that can trap moisture if circulation is poor. A well-tuned VPD (roughly 0.8–1.2 kPa across the grow cycle) will generally keep transpiration healthy, though exact targets will shift with your specific environment.

Training & canopy

This strain tends to suit a mix of topping and LST well. Topping early (around node 4–5) often encourages a multi-cola structure, and bending / LST during veg can spread the canopy efficiently. SCROG is a solid option if you want to even out its tendency toward unequal branch heights. Avoid heavy defoliation late into flower — keep it light and strategic to maintain airflow without stressing the plant.

Flowering

As a hybrid, Pineapple Express typically shows a moderate stretch in the first 2–3 weeks of the flip — expect somewhere in the range of 1.5–2× the pre-flip height, though pheno variation can shift this. The general arc: weeks 1–3 see rapid vertical growth and pistil development; weeks 3–5 bring bud stacking and resin development; weeks 6–8 are typically the ripening and maturation phase. Without confirmed breeder data on flowering time, plan for roughly 8–9 weeks of flower as a baseline, then trust your own trichome and pistil observations over any fixed calendar.

Difficulty

A balanced hybrid that rewards attentive growers; manageable but benefits from structural training and humidity control during late flower.
