Think Fast

Think Different × Dutch Photoperiod Hybrid

Think Fast is a sativa-dominant photoperiod strain developed by Dutch Passion, notable for its significantly shortened flowering time compared to traditional varieties. It was bred to offer growers the flexibility of photoperiod cultivation with the speed often associated with autoflowers, making it suitable for various climates and indoor setups.

Appearance

Think Fast produces medium-to-large conical colas characterized by dense flower clusters and a tendency for modest foxtailing under high heat. The calyx-to-leaf ratio is favorable, leading to efficient trimming. Pistils typically transition from light peach to amber as the plant matures. The buds are known for their tight structure and resinous coating, often retaining a sticky texture even after curing.

The vegetative structure often resembles a Christmas tree with a prominent central cola if left untrained, featuring moderate internodal spacing for good light penetration. While generally green, some phenotypes may display lilac or plum hues when exposed to cooler nighttime temperatures. Sugar leaves can develop a silvery appearance due to heavy resin coverage in the final flowering stages.

Aroma & Flavor

The aroma of Think Fast is described as bright and modern, combining citrus zest with herbaceous pine notes and a subtle sweet, floral undertone. Early in its flowering cycle, it emits a green, terpenic scent reminiscent of fresh basil and lemon peel. As it matures, the bouquet deepens, introducing notes of orange marmalade, crushed pepper, and pine resin.

The flavor profile mirrors its aroma, offering a complex blend of citrus, particularly lemon and orange, alongside earthy and floral characteristics. Hints of mint and honey may also be present, contributing to a refreshing and multi-layered sensory experience.

Effects

Think Fast is reported to provide a focused and uplifting experience, characteristic of its sativa-leaning genetics. Users often describe a clear-headed cerebral effect that can enhance concentration and productivity without leading to excessive sedation.

The strain's effects are generally considered moderate, making it suitable for daytime use. It is often sought after for its ability to help manage stress, providing a sense of calm and mental clarity.

Terpenes & Cannabinoids

Think Fast typically exhibits a chemotype skewed towards high THC levels, commonly ranging from 15-25%, with minimal CBD content (<1%). Terpene analysis, where available, frequently identifies Myrcene, Limonene, and Ocimene as dominant compounds, contributing to its distinct aroma and effects profile.

Growing Characteristics

Think Fast is a photoperiod strain specifically bred for accelerated flowering, typically shaving one to two weeks off standard photoperiod schedules. This makes it an attractive option for growers in temperate latitudes seeking earlier outdoor harvests or for indoor cultivators aiming for quicker crop cycles. It is generally considered moderately easy to grow, adapting well to various cultivation environments.

The strain's yield is considered robust, and it responds well to standard training techniques like topping and SCROG, offering flexibility for growers. Its shortened flowering time, often around 7-8 weeks, allows for multiple harvests per year indoors or completion before adverse weather conditions outdoors.

Origins and Lineage

Think Fast was developed by Dutch Passion, originating from Dutch breeding programs in the mid-2010s. The goal was to create a photoperiod strain with a significantly reduced flowering time without compromising potency or structure. It achieves this by incorporating genetics from an autoflowering line, Think Different, alongside a high-yielding, classic Dutch photoperiod parent.

The resulting hybrid retains photoperiod dependency but exhibits accelerated flower development. This unique breeding strategy results in a stable, fast-flowering photoperiod plant that offers improved crop cycle times for both indoor and outdoor cultivation, bridging the gap between autoflowers and traditional photoperiod varieties.
