How to Germinate Amnesia Lemon Seeds
A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Amnesia Lemon seeds inside two damp sheets, slide them between two plates, and keep them somewhere dark at 70 to 79°F. A taproot usually appears in two to five days.
Once the taproot is a few millimeters long, move each seed root-down about 1 cm deep into a small pot of light, airy medium. Keep it lightly moist rather than soaked, hold humidity around 65 to 70%, and give soft light while the first true leaves open. Its vigorous Haze-and-Skunk genetics make for a fast, dependable seedling.
Starter tips
- Use plain, lightly pH-balanced water (pH 5.5 to 6.5) for the first week.
- Keep seedlings warm and humid, but never waterlogged.
- Hold off on nutrients until the second set of serrated leaves appears.
Growing Amnesia Lemon in the Vegetative Stage
As a photoperiod plant, you control the veg stage with the light schedule. Keep Amnesia Lemon on 18 hours of light a day for as long as you want it to grow, aim for day temperatures of 68 to 79°F, and hold humidity around 50 to 60%. It suits a temperate climate, so steady, moderate conditions work in its favor. As a 70% sativa it grows tall and lanky with open internodal spacing, so plan for a plant that keeps reaching.
This is the stage to shape the plant. Because sativas stretch, topping early and using low-stress training to pull the branches outward keeps the canopy even and the height in check, especially indoors. A shorter veg before you flip helps manage the stretch, and a little support for the long branches pays off once the buds fill in.
Its reaching structure and October finish make it versatile both indoors and out:
- Temperate outdoor plots: its October harvest fits regions with warm summers and a dry early autumn.
- Mediterranean-style gardens: plenty of sun and space let it stretch out and fill its long colas.
- Indoor tents: keep veg short and train hard, as its sativa stretch will otherwise test the height of a tent.
Identifying the Sex of Your Plants
Because Amnesia Lemon is a regular strain, each seed can grow into a male or a female, so part of the job is to identify the sex before flowering goes far. Around one to two weeks into 12/12, small pre-flowers appear where the branches meet the main stem. Females show a tiny teardrop-shaped calyx with a pair of white hairs, while males form small round pollen sacs on a short stalk.
If your goal is buds, remove the males early, before the sacs open, so they cannot pollinate the females and fill your flowers with seeds. If you are breeding, this is exactly where regular seeds earn their place: you keep a healthy male to collect pollen and preserve or cross the Amnesia Lemon line, something feminized seeds cannot offer. Either way, check daily once pre-flowers show, as a single open male can pollinate a whole room.
Flowering and Buds of Amnesia Lemon
Indoors, flip Amnesia Lemon to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens through October. As a sativa it shows a significant stretch in the first weeks after the flip, so leave headroom, then forms long, resinous, spear-shaped colas.
Through bloom, drop humidity to 40 to 45% and keep air moving so the long flowers stay clean. The buds build a bright lemon-citrus aroma over a pungent, skunky, earthy base, the zesty Haze lift of Amnesia meeting the sharp, sour funk of Lemon Skunk.
At 18 to 22% THC it sits in the medium range, giving a focused, happy and relaxed effect, a clear-headed, functional lift with an easygoing finish.
Common Problems and Pro Tips
Amnesia Lemon is a rewarding grow, but its sativa stretch, pungent aroma and regular genetics point to a few things worth watching.
- Manage the stretch: as a 70% sativa it can nearly double in height after the flip, so keep veg short and train early to stay within your space.
- Control the smell: its lemon-skunk nose is loud in flower, so a carbon filter is close to essential indoors if odor matters.
- Watch for males: as a regular strain it will throw males, so check pre-flowers daily and pull them early unless you are breeding.
Expert tip: its lemon-skunk profile rewards a clean grow. Train hard in veg to tame the sativa stretch, and dry and cure slowly so the bright lemon holds up over its pungent, skunky base.
Aroma, Flavor and Effects
The nose is loud and zesty: a sharp lemon-citrus lift up front over a pungent, skunky, earthy base. It is a bold, sour-sweet profile that leans bright and funky rather than soft, true to its Amnesia and Lemon Skunk parents.
The flavor follows the nose, zesty lemon and citrus with a sharp, skunky, earthy finish. On the effect side it is focused, happy and relaxed, a clear-headed, functional lift. Because THC runs a moderate 18 to 22%, it stays rounded and approachable.
Dominant terpenes
Amnesia Lemon carries a bright, layered terpene profile. Terpinolene leads with a fresh, zesty, lemony-piney lift that drives its citrus side, Myrcene lays down an earthy, musky base that carries the skunk, Geraniol adds a sweet, floral-citrus note, Caryophyllene a warm, peppery spice, Pinene a sharp pine edge, and Humulene a dry, woody depth. A supporting cast of Linalool, plus Borneol and its isomer Isoborneol, rounds out its lemon, citrus, earthy and skunk character with soft floral and cool, camphor-like undertones.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. As a vigorous, high-yielding sativa Amnesia Lemon is a steady feeder, so read the plant first: tip burn means back off, while pale, slow growth means it wants a little more. All values use EC.
| Stage | EC |
|---|---|
| Seedling | 0.4–0.6 |
| Growth | 0.8–1.2 |
| Early flower | 1.2–1.4 |
| Full flower | 1.4–1.6 |
| Flush | 0.0–0.4 |
Keep the pH around 6.0 to 6.5 in soil and 5.5 to 6.0 in hydro so the roots can actually take up what you feed.
What to Do With Your Trim: Extracts and Hash
Amnesia Lemon builds a solid coat of resin, so its trim is worth keeping rather than tossing. The sugar leaves you take off while manicuring hold trichomes and suit Ice Water Hash, where cold water and agitation separate the resin heads into a clean, solventless concentrate. Pressing that hash into rosin keeps the bright lemon flavor intact, or you can run a solvent extraction if that is your setup. The bare stems will not extract, but chopped and composted they feed organic matter back into the soil for your next grow.
Harvesting, Drying and Curing Amnesia Lemon
Timing the harvest comes down to the trichomes. Grab a loupe and watch the heads turn from clear to milky white; a scattering of amber signals peak ripeness. Indoors this lands 8 to 10 weeks after the flip, and outdoors the plants are ready through October.
After the cut, hang the branches in a dark room at 59 to 68°F with humidity near 50% and gentle air movement. Slow beats fast: drying over 10 to 14 days protects the lemon, citrus and skunky aromas that define this strain. When the small stems snap instead of bending, move the buds into jars.
Cure in sealed glass, opening the jars daily for the first week to let moisture escape, then easing off as the aroma deepens. Two to four weeks of patience here is where the zesty lemon and pungent, skunky depth really come together, and it is the step most growers rush.
Frequently Asked Questions
Why are Amnesia Lemon seeds regular and not feminized?
Amnesia Lemon is sold as a regular strain, so it produces both males and females. That is exactly what breeders want: a male lets you collect pollen to cross or preserve the line, which feminized seeds cannot do. Many growers also value the vigor and stable, unmodified genetics of a regular strain.
How do you identify the sex of Amnesia Lemon plants?
About one to two weeks into 12/12, check where the branches meet the stem. Females show a small teardrop calyx with two white hairs, while males form round pollen sacs on a short stalk. If you are growing for buds, remove the males early so they cannot pollinate your females.
How long does Amnesia Lemon take to flower?
Amnesia Lemon flowers in 8 to 10 weeks once you switch it to a 12/12 light cycle indoors. Grown outdoors, it is ready through October. As a sativa it stretches hard in the first weeks after the flip, then forms long, resinous colas over that bloom window.
How strong is Amnesia Lemon?
Amnesia Lemon has a THC level of 18 to 22%, which places it in the medium range. The effect is focused, happy and relaxed, a clear-headed, functional lift with an easygoing finish. That moderate potency makes it a rounded, approachable strain for a wide range of growers and users.
How much does Amnesia Lemon yield?
Amnesia Lemon is high-yielding. Indoors it gives around 1.31 to 1.64 oz/ft², and outdoors a plant reaches roughly 15.87 to 19.4 oz in good conditions. Space, strong light and early training are what help this vigorous sativa fill out its long, resinous colas to their full potential.
What does Amnesia Lemon taste and smell like?
Amnesia Lemon leads with a sharp, zesty lemon-citrus aroma over a pungent, skunky, earthy base. It is a bold, sour-sweet profile rather than a soft one, true to its Amnesia and Lemon Skunk roots. Both the aroma and flavor deepen as the buds cure slowly after harvest.
