The EC16 The Krux Multipack celebrates one of the cornerstone females of Ethos Genetics: Ethos Cookies #16, better known as The Krux. Bred from Mandarin Cookies x Colin OG, she has fathered several of the breeder’s most successful lines, and this pack puts six of her crosses side by side.
One slot is a pure S1 of EC #16 itself, while the other five pair her with Purple Majik, Blueberry Muffin Bubba, Skunk Hero, GMO and Grape Diamonds. The family resemblance is a fruity, floral and sour citrus nose, with each partner adding its own twist, from purple berry and muffin sweetness to skunk and savory garlic funk.
Expect strong, vigorous plants that handle both indoor rooms and outdoor gardens, TAC up to 30%, and yields from average to extremely high. For anyone curious about the Ethos cookies strain family, this is a direct way to grow it out across six expressions.
Each pack holds 1, 3 or 5 feminized seeds of each of these six crosses (6, 18 or 30 seeds in total):
- EC #16 S1 (EC #16 x EC #16)
- Purple Majik x EC #16
- Blueberry Muffin Bubba x EC #16
- Skunk Hero x EC #16
- GMO x EC #16
- Grape Diamonds x EC #16
Lineage: The Krux and Her Partners
Ethos Cookies #16 combines the citrus-heavy Mandarin Cookies line with Colin OG, a fuel-forward OG. She became a key building block for Ethos Genetics and even sits in the background of the End Game line. In this pack she is used as the common parent for every seed.
The S1 slot is a selfed feminized line of EC #16, meaning she was crossed with herself. S1 seeds are the closest look at the mother’s own traits, though some variation still shows up. The other five crosses blend her with very different families: Purple Majik and Grape Diamonds lean toward color and grape, Blueberry Muffin Bubba brings bakery and berry notes, Skunk Hero adds classic skunk, and GMO pushes a savory, garlicky funk.
Aroma, Flavor and Effect
EC #16 is known for a fruity, floral and sour citrus profile, with mandarin peel on top and an OG base underneath. The partners widen that palette: berry and blueberry from the Bubba and Grape Diamonds crosses, sharp skunk from Skunk Hero, and a pungent savory edge from GMO.
The pack spans the whole classic spectrum, from indica to sativa leaning, depending on the cross. Some phenotypes offer a bright, social head high, while others slide into a heavier body calm, which makes it easy to find a plant that fits a preferred style.
Growing the EC16 The Krux Multipack Indoors and Outdoors
These crosses are described as strong and vigorous, with medium to tall frames and medium to long internodes. Indoors, top once or twice in veg and use LST or a SCROG net to keep the canopy flat. The plants respond well to training and fill a tent quickly.
Flowering runs from 56 to 70 days, with the faster crosses ready around eight weeks and some phenotypes asking for closer to ten. Watching trichome color is the easiest way to pick the right day for each plant in a mixed run.
