Manufacturer Information
Genetics & Origin of Blackwater
Blackwater combines two US lines: Mendo Purps and SFV OG Kush. Original Sensible Seeds describes the result as US genetics with purple flowers and Kush DNA – an almost pure Indica with 90% Indica and 10% Sativa. With up to 28% THC, it is, according to the breeder, one of the strongest strains in its catalogue; it does not state a CBD value. The plants stay compact and form very resinous, dense buds with a purple tinge. The manufacturer lists myrcene, caryophyllene and limonene as the main terpenes. The seeds are feminised and photoperiod, so flowering only sets in after the light cycle is switched. The breeder does not go into detail about which parent contributes which trait. You will find one of the two original lines from another breeder in our range: SFV OG Kush by The Cali Connection.
Who Is Blackwater For?
Blackwater is a high-yielding Indica with very high potency. It suits:
- Beginners in growing who are looking for a strain that, according to the manufacturer, is easy to cultivate
- Experienced consumers who appreciate a very strong Indica
- Indoor growers with limited height who need compact plants
- Outdoor gardeners for whom high mould resistance is important
- Lovers of purple flowers and berry-like grape aromas
It is less suitable for consumers with a low tolerance and for anyone who wants to keep a clear head during the day. You can find similarly strong strains under Super High THC Content.
Growing Blackwater: Indoor & Outdoor
Indoor Growing
Indoors, Blackwater is finished after 60 to 65 days of flowering, i.e. after around nine weeks. The plants reach 90 to 120 cm and keep a compact structure, which makes them interesting for tents with little headroom. Original Sensible Seeds states up to 700 g/m² – a top figure that presupposes good conditions. The flowers become dense and very resinous; so provide air movement in the canopy during the final weeks and keep an eye on the humidity. Cooler nights towards the end of flowering can support the purple tinge. If you are growing for the first time, you will find a guide under tips for beginners.
Outdoor Growing
Outdoors, Blackwater grows 140 to 180 cm tall and, according to the manufacturer, is ready for harvest from late September to early October. It states a yield of up to 900 g per plant. For outdoors, Original Sensible Seeds highlights the easy cultivation and a high mould resistance – a real advantage with dense Indica flowers in autumn. A sunny spot and supports for heavily laden branches help to make full use of the potential. Only grow where it is legal to do so.
Effect, Aroma & Terpenes of Blackwater
Blackwater smells sweet and fruity, of grape and lemon; for the flavour, Original Sensible Seeds names berries, grape and a lemony-fresh note. Elsewhere there is talk of dark berries, sweet grapes and a fresh lemon accent. The breeder lists myrcene, caryophyllene and limonene as the main terpenes; it does not publish measured values for them. It describes the effect as strongly euphoric and mood-lifting before it turns into a sedating deep relaxation – elsewhere it says: euphoric, relaxing, physically numbing. This suggests use in the evening. With up to 28% THC, Blackwater is very potent. So feel your way in with small amounts: how intense the effect is depends on dose and personal tolerance.
