About Blood Diamond
Genetics & strain profile
Blood Diamond is a feminized photoperiod strain. It comes from OG Kush; its second parent is not known. Also called Blood Diamond OG, it is an OG Kush-derived indica known for frosty, resin-loaded flowers and dense buds. It has 27% THC and 0.70% CBD, so it is very strong. It carries our harvest in October badge. The page gives no difficulty rating, and with this much THC it is not a first-grow pick.
It has one review, at five stars: the reviewer calls it an incredible strain with huge, fat buds and a huge plant, but also a slow finisher, saying that on October 1st it still had three to four weeks to go. That fits the page’s own October outdoor harvest and matches the October badge. One review is a very small sample. A photoperiod plant lets you decide when to start flowering, so you control how big it gets first. Our seeds are guaranteed, so if a seed does not come up, contact us.
How Blood Diamond grows
The plants typically stay in a medium height range, about 5 to 8 feet. Indoors it flowers in 8 to 10 weeks, with about 18 ounces per square metre, roughly 510 g/m². Outdoors, harvest is commonly in October in the Northern Hemisphere, with about 16 ounces per plant, roughly 450 g. October is late in much of Quebec and Ontario, so choose a sunny, sheltered spot and have a plan for early frost.
Because it is a photoperiod strain, it needs a change in light hours to flower: grow it under long days while it builds size, then switch to 12 hours of light and 12 of darkness indoors. Plants often stretch when the lights change, so plan your ceiling height before you switch. Start the seed at about 22 to 25 °C in a light, damp medium, water gently and feed lightly, and let the top layer dry between waterings. Dense, resin-loaded buds hold moisture, so keep airflow good late in flowering. Yields are best cases under good conditions, not promises. Harvest by the trichomes rather than by the calendar. Check your local rules before you plant.
Taste, aroma and effect
A bold, classic OG-style nose: bright citrus and pine. The effect is widely described as full-body and deeply relaxing. At 27% THC, newer consumers should start with a small amount, since effects vary from person to person. Any flowering cannabis gives off a smell, so plan for odour control indoors. For related strains, see High Octane, Larry OG and Purple Romulan.
