Big Bang

Big Bang Feminised Cannabis Seeds by Greenhouse Seeds

Big Bang is a feminised cannabis seed variety from Greenhouse Seeds that packs Skunk, Northern Light, and El Nino genetics into a squat, enormously productive plant. With 18–20% THC content, an 8-week flowering time, and yields that can hit 800 g/m² indoors, this is the strain commercial growers and medical cultivators keep coming back to. If you want a plant that grows wider than it does tall and fills every square centimetre of your canopy with dense, resinous buds, Big Bang delivers exactly that.

Big Bang Genetics: Skunk, Northern Light, and El Nino in One Seed

The breeding behind Big Bang reads like a greatest-hits compilation of indica-dominant genetics. Greenhouse Seeds crossed Skunk — the backbone of modern cannabis breeding — with Northern Light, then folded in El Nino (nicknamed "The Kid"). The result is a plant that inherits Skunk's vigour and resin production, Northern Light's compact structure and fast finish, and El Nino's weight. That triple cross is why Big Bang produces the kind of yields that make commercial growers pay attention: up to 800 g/m² indoors and up to 1 kg per plant outdoors.

We've seen growers underestimate how wide this plant gets. Big Bang genuinely tends to grow wider than it does tall, which makes it a natural candidate for the ScrOG (Screen of Green) method. Train her through a screen and she'll fill every gap with thick, candle-shaped colas covered in orange pistils and a blanket of trichomes. If you're used to stretchy sativas that need constant height management, Big Bang is the opposite problem — she stays low and bushy, and the challenge is giving her enough horizontal space.

Big Bang Yield and Flowering Time

Big Bang finishes flowering in approximately 8 weeks indoors, which puts it on the faster end for a plant this productive. At the 8-week mark you'll get solid results, but here's a tip we'd pass along: give her an extra week — push to 9 weeks — and the body-related effects become noticeably more pronounced. That additional week lets the trichomes mature further, shifting the cannabinoid and terpene profile toward a heavier, more physical result.

Why Big Bang Feminised Seeds Deserve a Spot in Your Grow Room

There are plenty of heavy-yielding strains on the market, but most of them come with trade-offs: long flowering times, lanky structures that need constant support, or genetics that are fussy about environment. Big Bang sidesteps all three. An 8-week finish means you can run more cycles per year. The naturally compact, bushy growth habit means less time spent training and fewer headaches with tent height. And the Skunk-Northern Light backbone gives this plant the kind of resilience that forgives the occasional missed feed or temperature swing.

For growers focused on medical applications, this strain has a track record. The combination of 18–20% THC with that indica-heavy genetic profile makes Big Bang well suited as a remedy for patients dealing with pain, anxiety, internal unrest, and lack of appetite. The dense bud structure and heavy resin coverage also make it an excellent candidate for extraction — if you're pressing rosin or making concentrates, the starting material is already loaded.

The honest limitation? The smell. We need to be blunt about this: Big Bang reeks. The Skunk genetics are utterly present in the aroma of this variety. Without proper ventilation and a good carbon filter, your entire house will know what you're growing. If you're in a shared building or anywhere discretion matters, sort your carbon filtration before you pop these seeds — not after. This is not a strain you can get away with growing behind a closed door and hoping for the best.

How to Grow Big Bang Feminised Seeds

1. Germinate your Big Bang seeds using the paper towel method or directly in a small pot of moist, lightly fertilised soil. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their final containers once they've developed 2–3 sets of true leaves. For ScrOG setups, 11–15 litre pots work well — Big Bang doesn't need massive root space because she stays compact.
3. Install a screen at roughly 40–50 cm above the pot rim. As Big Bang grows, tuck branches under the screen to encourage horizontal spread. Her natural tendency to grow wide makes this straightforward.
4. Switch to a 12/12 light cycle to trigger flowering once the screen is about 70% filled. Big Bang stretches minimally during the flip, so what you see is close to what you get.
5. Feed with a bloom-specific nutrient regime once flower sites appear. Big Bang is a heavy feeder during weeks 3–6 of flowering — she's building those dense, candle-shaped colas and needs the phosphorus and potassium to do it.
6. Monitor your carbon filter and extraction fan throughout flowering. The Skunk-dominant terpene profile kicks in hard around week 4 and only intensifies. Replace spent carbon if your filter is more than 12 months old.
7. Harvest at 8 weeks for a balanced effect, or push to 9 weeks if you want a heavier, more body-focused result. Check trichomes with a loupe — mostly cloudy with 10–20% amber is the sweet spot for that extra week.
8. Dry slowly in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in sealed glass jars for at least 2 weeks. Take care when smoking the cured product — the smoke expands significantly in the lungs, and a careless deep inhale will have you coughing hard.

Big Bang vs Other Greenhouse Seeds Strains

If you're comparing Big Bang to other Greenhouse Seeds varieties, the closest alternatives are Super Bud and White Widow. Super Bud matches Big Bang on yield but flowers a touch slower and doesn't have the same extreme bushiness — it's easier to manage in smaller spaces but won't fill a ScrOG screen as aggressively. White Widow offers a more balanced indica-sativa effect with slightly lower yields, and the smell is more manageable if discretion is a concern. We'd pick Big Bang over both if maximum yield per square metre is your primary goal and you've got your ventilation sorted. If smell control is a real constraint, White Widow is the safer bet.

What Big Bang Buds Look and Smell Like

When Big Bang is properly grown and cured, the buds are unmistakable. They form thick, candle-shaped colas — dense enough that you can feel the weight when you pick one up. The surface is covered in a multitude of orange stigmas weaving through a carpet of resin glands that catch the light. Break a bud open and the trichome coverage goes all the way to the stem.

The smell, though — that's what defines this strain. It's Skunk, front and centre, with very little subtlety. When you open a jar of cured Big Bang, the room fills up within seconds. It's pungent, dank, and earthy with a sharp, almost acrid edge. Some growers love it; others find it challenging to live with during the final weeks of flowering. Either way, you'll need to respect it. Double-bag your cured stash if you're storing it anywhere near living spaces.
