About Watermelon Wave

Watermelon Wave is a compact indica-dominant hybrid bred for fruity flavour and reliable indoor performance. It offers 18–22% THC, tight internodes and dense colas that suit greenhouse and small-space grows when humidity is managed carefully.

Grow Difficulty:

Under humid greenhouse environments, Watermelon Wave shows moderate growing demands and benefits from vigilant humidity control. It tolerates some moisture but needs airflow and regular pruning to prevent mould.

Flowering Time:

Flowering finishes in about eight to nine weeks under controlled conditions. Breeders report consistent bud development across runs.

Yield:

Yields are medium to high for a compact plant, commonly around 350–450 g/m² indoors. Greenhouse grows can push numbers higher with good climate and pest management.

Height:

Plants stay compact to medium, developing dense colas on short internodes. Expect mature heights around 60–120 cm indoors with bushy side-branching.

Environment:

Indoors it performs well in tight spaces, responding positively to SCROG and low-stress training. Outdoors in Derry it thrives best in a sheltered greenhouse rather than exposed sites.

Climate:

Growing Watermelon Wave in Derry requires attention to humid greenhouse environments and seasonal temperature swings. Maintain steady ventilation and dehumidification in the greenhouse to reduce mould risk in Derry.
