How to Grow Blue Amnesia Regular
Blue Amnesia reads like a meeting of two eras: Amnesia Haze, the Amsterdam cup legend, crossed with Blue Dream, California’s modern workhorse. Blue Amnesia Regular at Blimburn Seeds delivers that pairing in old-school regular seed, males and females both, the format breeders and purists still swear by.
The chemistry is serious: 22-24% THC in a 70% sativa frame, yet the effect stays remarkably workable, focused, happy and relaxed, the kind of flower that sharpens an afternoon rather than erasing it. The taste leans bright, citrus and spice over sweetness, with both parents audible in every draw. The Blue Dream mother is still in the catalog as Blue Dream for growers who want to compare.

| Lineage | Amnesia Haze x Blue Dream |
| Phenotype | 30% Indica / 70% Sativa |

| Flowering time | 8 – 10 weeks after the flip |
| Harvest month | October |
| Yield indoor | 1.47 – 1.8 oz/ft² (450 – 550 g/m²) |

For a 70% sativa with this potency, the logistics are kind: a 4.92 ft ceiling, standard 8-10 week flowering and generous returns both indoors and in the garden. The one skill it demands is the regular-seed workflow, covered next, and that skill pays for itself in breeding options.
Promos & Deals
Working with Regular Seeds
Plan for roughly half the seedlings to be male and germinate double the females you want to flower. The sexes reveal themselves at preflowering, sometimes in late veg: females push white, hair-like pistils at the branch joints, males hang small round pollen sacs like tiny grape clusters. Check every plant daily through the first two weeks after the flip, because one open male turns a sativa canopy into a seed farm.
Remove males promptly, but weigh the best one before it goes. A vigorous male carrying Amnesia Haze and Blue Dream is genuine breeding stock; collect its pollen in a separate room, store it cool and dry, and dust one lower branch of a chosen female if you want seeds of your own line without seeding the crop.
Getting Blue Amnesia Regular Started
Germinate at 70-79°F in paper towels or starter plugs; taproots show within three days. Raise all seedlings identically, same cups, same mix, same watering, so later differences are genetics rather than care, then pot the confirmed females up to 3-5 gallon containers.
Veg under 18 hours of light at 68-81°F with 50-60% humidity. Both parents contribute vigor, and the young plants grow quickly and upright with eager branching after topping. Three weeks of veg suits most tents, and many growers identify the sex from preflowers before the flip, saving space for females only.
Feeding Blue Amnesia Regular by EC
Confident feeding suits this cross, with haze-side caution late. Track EC, hold pH at 6.0-6.5 in soil, and taper early rather than late.
| Stage | Weeks | EC | Notes |
|---|---|---|---|
| Seedling | 1-2 | 0.4 – 0.6 | Plain water or very light feed |
| Vegetative | 3 | 0.8 – 1.2 | Nitrogen-leaning base nutrients |
| Preflower | Flip + 1-2 | 1.2 – 1.4 | Transition feed; sex the plants now |
| Bloom | Flip + 3-8 | 1.4 – 1.6 | Bloom base, add PK booster |
| Flush | Final 1-2 | 0.0 – 0.4 | Plain pH-corrected water |
Hold nitrogen through the energetic stretch, then shift to phosphorus and potassium as the long colas stack. Supplement calcium and magnesium under LED lights, and keep the bloom EC at the middle of the range in the final two weeks; overfed haze flower trades its bright citrus for a flat mineral edge.
The flush is where the flavor gets decided. Two clean weeks of water keep the citrus sharp and the sweetness honest.
Training Blue Amnesia Regular and Flipping to 12/12
Top once above the fourth node in week 2 or 3 and spread the mains with low-stress training into an open canopy with room between plants, because you will be removing males mid-grow and gaps close fast when 70% sativa branches stretch.
Flip to 12/12 at about 60% footprint coverage and do the daily sex checks through the stretch. Once only females remain, the show starts: two energetic weeks of stretch, then 8-10 weeks of long, resinous colas stacking in the haze tradition. Hold humidity at 40-45% from mid-bloom with honest airflow, and support the leaders by week 8.
Harvesting and Curing Blue Amnesia Regular
Start reading trichomes at week 7 of flower. Harvest at mostly cloudy with the first ambers for the focused, bright character this cross does best; at 22-24% THC there is no need to chase extra amber for strength. Outdoor plants in a temperate climate finish in October.
Dry for 10-14 days at 59-68°F and around 55% humidity, then cure in glass for at least two weeks with daily burping early on. The citrus leads the young jar, the spice emerges by week two, and the sweetness ties them together around week three, with the blue shading on well-grown buds making the name literal.
What to Do With Your Trim
Haze resin over Blue Dream terpenes makes aromatic processing material, and a regular-seed run usually leaves trim from several females at once. Dry-sift for bright citrus kief, wash bubble hash for a classic result, or infuse butter where the sweet side carries into edibles that deserve careful dosing at this potency.
Aroma, Flavor and Terpenes
Three terpenes map the citrus-spicy-sweet triangle precisely. Limonene leads, delivering the bright citrus zest that opens every jar, the clearest inheritance from the Amnesia side. Caryophyllene answers with warm pepper, the spicy middle that keeps the brightness from floating away.
Myrcene completes the arrangement with ripe, sweet fruit depth, the Blue Dream signature working underneath. It is a compact, legible profile that cures into excellent balance: zest on the inhale, spice through the middle, sweetness on the exhale, and more presence at week three than most longer terpene lists ever manage.
Common Problems and Pro Tips
Blue Amnesia Regular is a rewarding grow, but it is a potent 70% sativa with regular genetics and long stacking colas, so plan for all three.
- Sort the males early: as a regular strain it produces both sexes, so check pre-flowers and pull the males before pollen drops unless you are breeding.
- Manage the stretch: as a 70% sativa it grows upright with an energetic stretch, so train the tops and give it headroom to keep the canopy even.
- Support the stacking colas: it builds long, stacking colas that get heavy late in bloom, so stake or tie the branches before they start to lean.
Expert tip: at 22 to 24% THC this is a strong one. Its bright citrus over Blue Dream fruit with a warm spice locks in after two to three weeks of curing, so dry slowly and be patient.
Frequently Asked Questions
Are Blue Amnesia Regular seeds feminized?
No. Regular seeds produce males and females in roughly equal numbers. You identify the sex at preflowering, remove the males before pollen drops, and flower the females, the traditional workflow and the one that makes home breeding possible. Check the pre-flowers early so you catch the males in time.
What is the Blue Amnesia strain?
Blue Amnesia is a 70% sativa cross of Amnesia Haze and Blue Dream, sold by Blimburn Seeds in regular seed form. It pairs 22 to 24% THC with a focused, happy effect and a citrus-spicy-sweet flavor profile, so you get a potent, energetic sativa in the breeder-friendly regular format.
How strong is Blue Amnesia Regular?
Flowers test at 22 to 24% THC, firmly in the high band and faithful to both parents’ reputations. The focused, clear character keeps it workable, but newcomers should approach it with respect. For growers, harvest on your preferred trichome reading to land the potency where you want it.
Is Blue Amnesia an indica or a sativa?
It is 70% sativa and 30% indica, visible in its upright growth, energetic stretch and long stacking colas, and audible in the focused, upbeat effect. The indica share keeps the height at a manageable 4.92 ft, but you should still train the tops to keep the canopy even and well lit.
How much does Blue Amnesia Regular yield?
Female plants deliver 1.47 to 1.8 oz/ft² (450 to 550 g/m²) indoors and 12.35 to 15.87 oz (350 to 450 g) each outdoors, generous returns that reward the extra work of the regular-seed format. Supporting the long stacking colas helps the plant reach the top of that range at harvest.
What does Blue Amnesia Regular taste like?
Bright citrus up front, warm spice through the middle and ripe sweetness on the exhale, Amnesia zest over Blue Dream fruit. The balance locks in after two to three weeks of curing in glass, so dry slowly in a cool, dark space and give it that time before you judge it.
