How to Grow Critical x Amnesia

Critical x Amnesia is an indica-dominant feminized strain (60% indica), a cross of the heavy-yielding Critical with the classic Amnesia. A Spannabis 2015 winner, it pairs a 19 to 22% THC level with an earthy, lemon and sweet flavor and a creative, euphoric and relaxed effect. As a feminized strain it grows nothing but flowering females, so every seed goes toward your harvest. This guide walks you through the whole grow, from germinating the seeds to the final cure.

It is a tall, vigorous plant that can reach 3 m, flowers in 8 to 10 weeks, and finishes outdoors in October with a heavy, high yield. Award-winning genetics, a bright lemon profile and forgiving growth make it rewarding, as long as you give it the room its height demands.

Critical x Amnesia at a Glance

Before you plant anything, it helps to see the full picture in one place. Here is the quick profile for this tall, lemon-forward indica, taken straight from the strain’s grow data.

These are feminized seeds, so you skip the guesswork of males and grow a full room of flowering females. Its 60% indica lean places it among the indica seeds, and its heavy harvest earns it a spot with the high-yielding seeds. Its Spannabis 2015 win also puts it in good company among the award-winning seeds.

How to Germinate Critical x Amnesia Seeds

A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Critical x Amnesia 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, Critical-backed genetics make for a strong, dependable seedling, which is part of why it suits first-time growers.

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 Critical x Amnesia in the Vegetative Stage

As a photoperiod plant, you control the veg stage with the light schedule. Keep Critical x Amnesia 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. Be ready for its size: this is a tall strain that can push to 3 m, so plan the space before it stretches.

This is the stage to get the height under control. Topping the plant early and using low-stress training to bend the branches outward keeps it shorter and wider, which is far easier to manage indoors and spreads light across the whole canopy. Even as a beginner-friendly strain, that early training is what turns its vigorous Amnesia-driven frame into an even, productive plant rather than one tall, leggy cola.

Flowering and Buds of Critical x Amnesia

Indoors, flip Critical x Amnesia to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens in October. Its Amnesia heritage drives a strong stretch early in bloom, then it fills out with long, resin-coated colas backed by Critical’s productivity.

Through bloom, drop humidity to 40 to 45% and keep air moving so the dense flowers stay dry and mold-free. The buds build an earthy base lifted by a zesty lemon note and a sweet finish, the bright, citrus-forward character that earned its Spannabis win.

At 19 to 22% THC it sits comfortably in the medium range, giving a creative, euphoric and relaxed effect, an upbeat, inspired feel grounded by its indica body.

Common Problems and Pro Tips

Critical x Amnesia is a forgiving grow, but its height, dense buds and bright aroma point to a few things worth watching.

• Manage the height: at up to 3 m it needs space and early training, so top it and tie down the branches to keep it indoor-friendly.
• Protect the dense buds: its resinous colas can trap moisture, so keep humidity down and air moving in late flower to avoid mold.
• Control the smell: its earthy-lemon nose carries in flower, so a carbon filter helps indoors if odor matters.

Expert tip: its lemon profile rewards a clean, slow finish. Train for an even canopy early, then dry and cure patiently so the zesty lemon and sweet notes hold up over its earthy base.

Aroma, Flavor and Effects

The nose is bright and grounded at once: a zesty lemon lift over a deep earthy base, with a sweet undertone. It is a fresh, citrus-forward profile that carries the classic Amnesia tang, rounded out by a candy-like sweetness.

The flavor follows the nose, zesty lemon and sweetness over an earthy finish on the exhale. On the effect side it is creative, euphoric and relaxed, an upbeat, inspired feel grounded by its indica body. Because THC runs a medium 19 to 22%, it stays balanced and expressive rather than overwhelming.

Dominant terpenes

Critical x Amnesia carries a bright, lemon-forward terpene profile. Limonene drives the zesty lemon that defines its nose, Myrcene lays down a soft, earthy base, and Caryophyllene adds a warm, peppery edge. Pinene brings a clean pine freshness and Linalool a gentle floral touch, together framing its earthy, lemon, sweet character.

Nutrient Schedule

Treat the figures below as a starting map, not a rulebook. As a vigorous, high-yielding indica Critical x Amnesia is a hearty 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.

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

Critical x Amnesia builds a good 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 zesty 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 Critical x Amnesia

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 in 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 earthy, lemon and sweet 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 sweet notes really come together, and it is the step most growers rush.
