GBS#4
Also known as: Grapefruit Bubblegum Sour #4
What is the GBS#4 strain?
GBS#4 is a hybrid cannabis strain with up to 24.0% THC, known for its relaxed effects and candy and citrus flavor profile.
GBS#4, also known as Grapefruit Bubblegum Sour #4, is a relatively rare cannabis strain that appears to be a phenotype selection from a broader GBS breeding project. The strain's exact origins are somewhat obscure in mainstream cannabis literature, suggesting it may be a boutique or regional cultivar. Based on its name and reported characteristics, it likely represents a specific phenotype expression from a cross involving grapefruit, bubblegum, and sour genetics, with the #4 designation indicating it was the fourth selected phenotype from that breeding batch.
The strain typically produces medium-sized, dense buds with a complex visual appearance. Flowers often display a mix of deep green and purple hues, complemented by vibrant orange pistils and a generous coating of trichomes. The buds are usually tightly structured with a resinous texture that makes them slightly sticky to the touch. The plant structure tends to be bushy with strong lateral branching, characteristic of many modern hybrid cultivars.
GBS#4 is noted for its distinctive aromatic profile that combines multiple scent families. The name suggests a primary terpene expression featuring grapefruit citrus notes, sweet bubblegum undertones, and the characteristic sour or diesel-like aroma common in many modern hybrids. This combination creates a complex sensory experience that evolves as the buds are broken apart and consumed. The strain's rarity means comprehensive documentation is limited, and much information comes from grower reports rather than formal laboratory studies.

How do you grow GBS#4?
GBS#4 is considered a moderate-difficulty strain to cultivate, suitable for growers with some experience. The flowering time typically ranges from 8 to 10 weeks when grown indoors. Outdoor harvest in northern hemisphere climates usually occurs in mid to late October. Plants tend to be medium in height, reaching 3-5 feet indoors and 4-7 feet outdoors with proper training. Yield is moderate to high, with indoor growers reporting approximately 14-18 ounces per square meter under optimal conditions. The strain performs well in both indoor and outdoor environments but prefers a Mediterranean-like climate when grown outside. Special considerations include maintaining stable humidity levels during flowering to prevent mold, as the dense buds can be susceptible to moisture-related issues. The plants respond well to low-stress training (LST) and screen of green (SCROG) techniques to maximize yield. Nutrient requirements are moderate, with some growers noting sensitivity to nitrogen in the flowering stage.
