Black Jack Feminized Cannabis Seeds grow best in warm, sunny climates and produce medium-sized plants that deliver impressive harvests. Although its exact flavors are unknown, with genetics like Jack Herer and Black Domina, you can expect a complex mix of spicy, earthy, and sweet undertones. Originally developed by Sonoma Seeds and now available through Rocket Seeds, this strain is known for producing generous yields whether grown indoors or out. With its balanced nature and feminized genetics, growers can count on consistent plants that provide reliable results.
Black Jack Feminized Marijuana Seeds grow well in warm, sunny environments and perform reliably in both indoor and outdoor setups. Plants reach a medium height in either setting, making them manageable for most growers. Expect generous yields around 500–600g/m² indoors and similar output outdoors. Flowering usually finishes within 8 to 9 weeks, and outdoor harvest falls around mid-October. Thanks to its balanced genetics and stable growth habits, Black Jack is a solid pick for cultivators looking for both high yield and quality.
Black Jack is the result of combining Black Domina and Jack Herer.
Since it’s a Balanced Hybrid, it works well during both day and night depending on how much you consume.
Both indoor and outdoor grows can yield up to 600g/m² or per plant with good care.

Joshua Tim –
Black Jack was a nice surprise! easy to grow and didn’t give me much trouble at all. The buds were super frosty and had this kinda spicy smell to them. The high hit right in the middle not too sleepy, not too hyped. honestly, perfect for chill days or creative stuff.
