Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.
CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.
Source: CTU strain dataset (public strain listings and breeder info, checked by CTU), verified Oct 2026. Potency, flavor and effects vary by grower, batch and plant. Facts no source lists are left out.

About Watermelon Punch
Watermelon Punch is a hybrid cannabis strain credited to CRU Cannabis. Public lineage data lists it as a cross of Purple Punch and Watermelon.
Watermelon Punch THC level
Public listings give Watermelon Punch a THC level of 12%, which is below most strains we track. Compared with all strains in our research dataset that have their own THC figure, it is higher than roughly 4% of them. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.
Watermelon Punch aroma, flavor and terpenes
Its most-reported flavor notes are grape, diesel and mango. Its top listed terpenes are myrcene (earthy, musky), terpinolene (fresh, herbal) and pinene (pine). Myrcene is the lead terpene for about 44% of the high-confidence strains in our dataset, so it is a common profile. Terpenes shape smell and taste; their levels change from batch to batch.
Reported effects of Watermelon Punch
Commonly reported effects: energetic, relaxed, happy, euphoric and creative. These are user reports, not promises. Effects differ from person to person and depend on dose, setting and tolerance.
