Lebron Haze XXL Auto Cannabis Seeds by BSF Seeds
Lebron Haze XXL Auto is an autoflowering feminised cannabis seed from BSF Seeds that crosses the original Lebron Haze with a Jack Herer Auto F4 male. The result is a sativa-dominant hybrid (70/30) that grows fast, yields generously, and fills the room with a sharp lemon-and-pine aroma that lingers on your fingers long after you've handled the buds. If you want a citrus-forward auto that doesn't need babysitting, this is the one we'd point you to first.
BSF Seeds — short for Bigger, Stronger, Faster — built their reputation on autos that actually deliver on yield promises, and Lebron Haze XXL Auto is a good example of why. She reaches up to 1.5m, which is tall for an auto, and finishes in 60–65 days from germination. That's just over two months from cracking the seed to trimming the harvest. No photoperiod flip, no light schedule changes mid-grow — set your timer to 20/4 and let her do the rest.
Lebron Haze XXL Auto Seed Variant — What You Get
This listing comes as a pack of 4 feminised autoflowering seeds. Every seed is female, so there's no need to sex your plants or worry about rogue males pollinating your crop. Four seeds is enough for a solid indoor run under a single light, or a small outdoor patch if you've got a sunny balcony or garden spot.
Pack size: 4 feminised autoflowering seeds per pack. One phenotype, one SKU — no variant confusion here.

Why Lebron Haze XXL Auto Seeds Are Worth Growing
We've seen plenty of autos that promise big yields and then produce wispy, airy buds that weigh next to nothing once they're dry. Lebron Haze XXL Auto isn't one of those. The Jack Herer Auto F4 parentage gives her genuine structure — tight, dense buds that stack well along the main cola and side branches. Indoor growers pulling 450–550 g/m² from an auto in 60–65 days are getting photoperiod-level returns on an autoflowering timeline. That's the real selling point here.
Outdoors, yields range from 40–250 g per plant. That's a wide spread, and honestly, the lower end reflects plants that didn't get enough direct sunlight or were started too late in the season. Give her a south-facing spot with 8+ hours of sun and decent soil, and she'll lean heavily toward the upper end of that range. The 1.5m height means she won't tower over your fence, but she's big enough to develop a proper canopy.
The one thing to watch: she's a sativa-dominant auto, which means she can stretch during the first few weeks. If you're growing in a small tent — say a 60x60 — you might need to do some light LST (low-stress training) early on to keep the canopy even and prevent her from getting too close to your light. In an 80x80 or larger, she'll have plenty of room to do her thing without intervention.
Flavour and Aroma Profile of Lebron Haze XXL Auto
This is where Lebron Haze XXL Auto really stands out from the auto crowd. Crack open a cured bud and you get hit with a wave of sharp, zesty lemon — not the vague "citrus notes" you read about on every other seed listing, but a genuine, deep lemon scent that fills the room. It smells like someone zested a whole lemon into a bag of fresh haze.
Underneath that citrus top note, there's a woody, piney base that comes through more clearly on the exhale. The flavour matches the nose almost exactly: lemon up front, pine and haze on the back end. If you've grown or smoked the original Lebron Haze, you'll recognise the citrus profile immediately — the Jack Herer Auto parentage just adds a bit more complexity and depth to the woody undertones.
For the best flavour, cure your buds for at least two weeks in glass jars, burping daily for the first few days. The terpene profile develops noticeably between week one and week three of curing. Rush the dry and you'll lose a lot of that lemon sharpness.
How to Grow Lebron Haze XXL Auto Cannabis Seeds
- Germinate your seeds using the paper towel method or by placing them directly into a moist jiffy pellet or small pot of seedling soil. Taproots typically appear within 24–72 hours.
- Transplant carefully (or don't transplant at all). Autos don't love being moved once they've started growing. We'd recommend planting directly into your final pot — an 11–15 litre container works well. This avoids transplant shock that can stunt an auto's short vegetative phase.
- Set your light schedule to 20 hours on, 4 hours off. BSF Seeds specifically recommends this cycle for Lebron Haze XXL Auto. Some growers run 18/6, but the extra two hours of light during the auto's short life cycle can make a real difference to final yield.
- Feed lightly during the first two weeks, then gradually increase nutrients as she enters pre-flower. Autos are sensitive to overfeeding, especially in the seedling stage. A light, well-aerated soil mix with perlite will help prevent root issues.
- Watch for stretch in weeks 2–4. As a sativa-dominant auto, she'll put on height quickly. Apply gentle LST if needed — bend the main stem and tie it down to open up the canopy and encourage even bud development across multiple tops.
- Begin flushing 7–10 days before harvest. At around day 50–55, check the trichomes with a jeweller's loupe. When most are milky with a few turning amber, start your flush. Harvest between day 60–65 for the best balance of potency and flavour.
- Dry in a dark room at 18–20°C with 55–60% humidity for 7–10 days, then transfer to glass jars for curing. The lemon terpenes in this strain are volatile — a slow dry preserves them.
Lebron Haze XXL Auto vs Other Citrus Autos
If you're comparing citrus-forward autos, the obvious alternatives are Lemon Haze Auto and Jack Herer Auto. Lebron Haze XXL Auto sits in an interesting spot between the two — she's got the sharp lemon profile of a Lemon Haze but with the structural density and woody undertones you'd expect from Jack Herer genetics. Yield-wise, 450–550 g/m² indoors puts her at the top of the auto league. Most standard Lemon Haze Autos top out around 400 g/m², so the XXL tag isn't just marketing.
The 19% THC is solid but not extreme for a modern auto. If you're chasing the highest possible THC number, there are autos pushing 23–25% — but they often sacrifice flavour complexity to get there. Lebron Haze XXL Auto is the better pick if terpene profile matters to you as much as raw potency.
| Trait | Lebron Haze XXL Auto | Typical Lemon Haze Auto |
|---|---|---|
| Genetics | Lebron Haze x Jack Herer Auto F4 | Lemon Haze x Ruderalis |
| THC | 19% | 15–20% |
| Indoor Yield | 450–550 g/m² | 350–450 g/m² |
| Seed to Harvest | 60–65 days | 65–75 days |
| Height | Up to 1.5m | 0.8–1.2m |
| Dominant Terpenes | Lemon, pine, haze | Lemon, sweet citrus |
Growing indoors? Pair these seeds with a complete grow tent kit — tent, light, carbon filter, and extraction fan in one box. If you're already set up, grab a jeweller's loupe for trichome checking and a set of plant ties for LST. Outdoor growers will want a good-quality fabric pot (15 litre minimum) and a reliable soil mix with added perlite.
