Chemdog 4 by Blimburn Seeds

Chemdog 4 seeds: the Chem family with a spark of Green Crack

Chemdog 4 is Blimburn Seeds' take on a legendary name in US cannabis culture. The breeder does not sell the original clone: it crosses Chemdawg, famous for its diesel smell, with Green Crack, a strain known for its awake, alert effect. The result is a hybrid (a mix of indica and sativa genetics) that is 60 % indica and 40 % sativa. The seeds are feminized (they only grow female plants, the ones that produce buds), so you waste no space on males. At oaseeds we like it because it brings together the chemical, potent character of the Chem family and a grow that Blimburn rates as beginner-friendly, which is rare in this line.

Flavour, aroma and effect of Chemdog 4

Blimburn describes a strong citrus profile, with lemon up front, over a base of diesel, fuel and a hint of ammonia that recalls the classic Chems. The terpenes (the compounds that give the plant its smell and taste) the breeder highlights are caryophyllene, humulene, linalool, myrcene and alpha-pinene: spicy, floral, earthy and pine notes. The buds come out rock hard and so covered in trichomes (the resin glands that sparkle on the flower) that they look frosted.

THC (the main psychoactive compound in cannabis) ranges from 18 to 26 %. According to the breeder, the effect is strong and relaxing in the body, with a happy mood and a chatty streak. It is a good pick for winding down from stress at the end of the day.

How to grow Chemdog 4 indoors and outdoors

Chemdog 4 is photoperiodic (it flowers when the days get shorter, not with age), so indoors the flowering stage (the phase when the plant forms its buds) starts when you cut the hours of light. It lasts 7 to 9 weeks. Blimburn gives a yield of 450 to 500 g/m² and a height of about 1.5 m, so in low tents it pays to train the plant. The breeder recommends keeping relative humidity at 55 to 60 % during growth and lowering it to 40 % in flowering, which matters with buds this dense, as they hold moisture and can catch mould.

Outdoors it wants a temperate climate, with mild summers and autumns without cold. There each plant can give 600 to 700 g, and in the northern hemisphere you harvest in September. Being compact and hardy, the breeder rates it as easy. A tip: thanks to its heavy resin production it is a good candidate for extracts, so keep your trim.
