Moby-D XXL Auto Cannabis Seeds by BSF Seeds
Moby-D XXL Auto is an autoflowering feminised cannabis seed that delivers Haze-dominant genetics with yields rivalling photoperiod strains — up to 600g/m² indoors from seed to harvest in just 77–80 days. BSF Seeds created this hybrid by crossing their own Moby-D Auto with a top-performing Haze Auto, resulting in a third-generation autoflower with enormous calyxes, heavy resin production, and a pine-and-lemon Haze aroma that deepens during the cure. If you want sativa-leaning auto seeds that actually produce serious weight, this is where you start.
Why Moby-D XXL Auto Seeds Stand Out
Most autoflowers force a trade-off: you get speed but sacrifice yield, or you get decent buds but they're small and airy. Moby-D XXL Auto sidesteps that compromise entirely. BSF Seeds combined two third-generation autoflowering hybrids — their Moby-D Auto and a high-performing Haze Auto — specifically to increase plant size and, most critically, bud size. The result is an autoflower that genuinely competes with photoperiod Haze and Moby Dick strains on yield.
The 80% sativa genetics show up in the growth pattern: tall, stretchy plants that absorb every photon you throw at them. Run her under at least 600W HPS on a 20/4 light cycle and she'll reward you properly. The buds swell with aromatic resin right up until harvest, and the pine-lemon Haze scent is unmistakable — sharp, citrusy, with a resinous pine backbone that sticks to your fingers during trimming. Cure them for a few weeks and the terpene profile only gets richer.
One honest limitation: these plants get big for autos. If you're working in a tight space — say a 60x60 tent — you'll need to plan ahead. Give them more room than you'd normally reserve for autoflowers, or you'll end up with branches fighting for light. In a 2x4 space with multiple plants, one grower reported pulling just under 2 oz per plant, noting he could have gotten significantly more without the crowding. Space is the variable here, not genetics.

Moby-D XXL Auto Growing Tips
These seeds are vigorous from the moment they crack. The sativa stretch is real, so you need a plan before you pop them. Here's what we'd do:
- Germinate using the paper towel method or directly in a small pot of light, airy substrate. Taproots typically appear within 24–72 hours.
- Transplant into your final container early — 15–20 litre pots minimum. Autos don't like root disturbance, and these plants need room to stretch. Fabric pots work well for the air pruning.
- Set your light cycle to 20/4 from day one. Moby-D XXL Auto is a light-hungry sativa; she'll absorb everything you give her. A 600W HPS or equivalent LED is the minimum for serious results.
- Feed heavily once she hits vegetative stride. BSF Seeds rates the nutrient requirement as high. Increase nitrogen during veg, then switch to a bloom-heavy feed as soon as you see the first pistils — which happens automatically around weeks 3–4.
- Use stakes or a trellis net for support. The buds get heavy and the branches are long. Without support, you'll find colas bending under their own weight in the final weeks.
- Harvest when trichomes show mostly milky with a few amber — typically around day 77–80 from seed. The sativa-dominant genetics mean the energetic effect is strongest when you don't let her go too long.
- Cure for at least 2–3 weeks in glass jars, burping daily for the first week. The pine and lemon Haze terpenes deepen noticeably during the cure — don't rush this step.
Moby-D XXL Auto Compared to Other Autoflowering Seeds
If you're weighing up your options, here's how Moby-D XXL Auto stacks up against two other popular autos in the BSF Seeds catalogue:
| Feature | Moby-D XXL Auto | Auto Frozen Biscotti | Cheese Wizard Auto |
|---|---|---|---|
| Sativa/Indica | 80% Sativa | Indica-dominant | Indica-dominant |
| Seed to Harvest | 77–80 days | 70–75 days | 70–75 days |
| Indoor Yield | Up to 600g/m² | Moderate-High | Moderate-High |
| Aroma Profile | Pine, lemon Haze | Sweet, biscuit, earthy | Cheese, earthy |
| Effect Character | Energetic, sativa-dominant | Relaxing, body-focused | Relaxing, mellow |
| Best For | Daytime use, sativa fans | Evening use, flavour chasers | Evening use, cheese lovers |
The difference is clear: Moby-D XXL Auto is the sativa pick. If you want that classic Haze character — the long-lasting, energetic, cerebral effect — with autoflowering convenience, this is the best autoflowering Haze seed for yield-focused growers. The indica-leaning alternatives from BSF are solid for evening use, but they won't give you the same daytime energy or the same ceiling on production.
Aroma, Flavour, and What to Expect from Moby-D XXL Auto
Crack open a cured jar of Moby-D XXL Auto and the first thing that hits you is sharp lemon Haze — zesty, almost cleaning-product bright — layered over a deep, resinous pine base. It smells like walking through a conifer forest with a bag of lemons in your pocket. The buds themselves are dense for a sativa, coated in a thick layer of trichomes that makes them sticky to the touch and almost white under direct light.
The smoke carries that same pine-lemon profile. Rich, full Haze flavour coats the tongue — not subtle, not background. The effect follows quickly: an upward lift, a burst of energy, and a clear-headed focus that lasts for hours. This is a daytime strain through and through. We'd keep it away from the evening rotation unless you're deliberately pulling an all-nighter. The 80% sativa genetics deliver exactly the intensity you'd expect — long-lasting, stimulating, and strong.
Complete your setup: Moby-D XXL Auto's heavy feeding schedule and large plant size pair well with a proper grow tent kit — look at our complete indoor grow kits if you need lighting, ventilation, and a carbon filter sorted in one go. For support during flower, grab a scrog net or a set of bamboo stakes to keep those heavy Haze colas upright.
Frequently Asked Questions
How long does Moby-D XXL Auto take from seed to harvest?
77 to 80 days from germination to harvest. That's the full cycle — no separate veg and flower phases to manage. Just plant, grow, and chop around day 77–80 when trichomes are mostly milky.
What yield can I expect from Moby-D XXL Auto indoors?
Up to 600g/m² indoors under strong lighting (600W HPS or equivalent LED) with a 20/4 light cycle. Outdoors, expect 70–230g per plant depending on conditions. Cramped grow spaces will reduce yield significantly.
Is Moby-D XXL Auto suitable for beginners?
Yes. The autoflowering genetics remove the need for light schedule changes or plant sexing. The main thing to get right is feeding — nutrient demand is high — and giving the plants enough space. Follow a basic feeding chart and you'll be fine.
How tall does Moby-D XXL Auto grow?
Medium height for an auto, but taller than most indica-dominant autos due to the 80% sativa genetics. Plan for more vertical and horizontal space than you'd normally give an autoflower. Stakes or a trellis net are recommended.
What does Moby-D XXL Auto smell and taste like?
Sharp lemon Haze with a deep pine resin base. The aroma is strong during flowering — a carbon filter is not optional if discretion matters. The flavour carries through in the smoke: rich, full Haze that coats the tongue. Curing for 2–3 weeks deepens the terpene profile.
What light cycle should I use for Moby-D XXL Auto?
20 hours on, 4 hours off (20/4) from seed to harvest. As an autoflower, she doesn't need a 12/12 flip to trigger flowering. She's a light-hungry sativa — give her as much as you can without running 24/0, which offers diminishing returns.
How many seeds come in a pack of Moby-D XXL Auto?
Each pack contains 4 feminised autoflowering seeds.
