Black Radler

Black Radler – James Loud Seeds

Black Radler Feminized by James Loud is a balanced cross of Black Lime Reserve x Double Lemon Cherry that combines intense citrus aromas with fruity cherry notes and a subtle earthy base. The mother line, Black Lime Reserve, is crossed here with Double Lemon Cherry, creating an interesting combination of lime, lemon and sweet-and-sour cherry. The wonderful aroma ranges from fresh, slightly tart lime notes and sweet citrus fruits to ripe cherries and pronounced sour cherry nuances. Earthy undertones complement the fruity aroma and give Black Radler a distinctive, complex character.

According to James Loud, Black Radler develops medium-sized plants with a hybrid growth structure. The flowering time is approximately 63 days, giving the strain a relatively manageable flowering period. The plants can develop compact, colorful flowers whose appearance may vary depending on the phenotype, and the strain is ideally suited for both outdoor and indoor cultivation. 

Particularly characteristic is the interplay of zesty lime, fresh lemon and sweet-and-sour cherry aromas, rounded off by subtle earthy notes. By combining Black Lime Reserve and Double Lemon Cherry, James Loud brings together two genetic lines to create a distinctive hybrid strain with an aromatic focus clearly centered on citrus fruits and cherries. The combination of medium height, around nine weeks of flowering and a multifaceted fruit profile makes Black Radler particularly interesting for enthusiasts of unusual cannabis aromas.
