How to Germinate Alien Technology x Do-Si-Dos Seeds
A healthy harvest starts at germination. The paper towel method is hard to beat: fold the Alien Technology x Do-Si-Dos 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 sturdy indica genetics make for a strong, 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 Alien Technology x Do-Si-Dos in the Vegetative Stage
As a photoperiod plant, you control the veg stage with the light schedule. Keep Alien Technology x Do-Si-Dos 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 heavy 80% indica it grows into a sturdy, bushy plant, though its Afghani line still reaches a respectable 1.6 m.
This is the stage to shape the plant. Because it bushes out, topping early and using low-stress training to spread the lower branches opens up the canopy, improves airflow, and lifts the yield. Give it room so light reaches the inner buds, and its dense structure rewards the effort with even, resinous flowers.
Its sturdy, kushy build and October finish make it a strong plant both indoors and out:
- Temperate outdoor plots: its October harvest fits regions with mild summers and a dry early autumn.
- Mediterranean-style gardens: steady warmth and good airflow let it stack its dense, resinous buds through flower.
- Indoor tents: at around 1.6 m with a bushy build, it stays manageable under lights with a little training.
Flowering and Buds of Alien Technology x Do-Si-Dos
Indoors, flip Alien Technology x Do-Si-Dos to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens through October. As a heavy indica it shows only a modest stretch after the flip, then packs on dense, resinous, chunky buds.
Through bloom, drop humidity to 40 to 45% and keep air moving so the tight flowers do not trap moisture. The buds build an earthy, kushy aroma with a sweet, citrus-tinged lift, the Do-Si-Dos sweetness meeting the deep, Afghani-rooted kush of its Alien Technology side.
At 20 to 25% THC it runs from medium to high, giving a focused, happy and relaxed effect, a comfortable, grounded feel that leans more potent than a mild strain.
Common Problems and Pro Tips
Alien Technology x Do-Si-Dos is a rewarding grow, but its dense buds and deep indica build point to a few things worth watching.
- Bud rot in dense colas: its tight, resinous flowers can trap humidity, so keep a fan moving and humidity below 45% late in flower.
- Even canopy: as a bushy indica, a little training keeps the lower buds productive and airflow good.
- Feed steadily, not heavily: with a medium yield it does not need a heavy nutrient load, so build up slowly and watch for tip burn.
Expert tip: its kush-and-citrus profile rewards a clean grow. Keep an even canopy during veg, and dry and cure slowly so the sweet citrus lift holds up over its deep, earthy kush base.
Aroma, Flavor and Effects
The nose is deep and grounded: an earthy, kushy base with a sweet lift and a bright citrus edge on top. It is a rich, savory-sweet profile that leans more earthy and hashy than fruity, true to its Afghani and Do-Si-Dos roots.
The flavor follows the nose, earthy kush and sweetness with a citrus finish. On the effect side it is focused, happy and relaxed, a comfortable, grounded feel. Because THC runs from a medium to high 20 to 25%, it leans more potent while staying balanced.
Dominant terpenes
Alien Technology x Do-Si-Dos carries a deep, earthy terpene profile. Myrcene lays down the earthy, kushy base, Caryophyllene adds a warm, peppery spice, Humulene a dry, woody depth that leans into its hashy side, Pinene a fresh pine lift, Terpinolene a bright, zesty edge, and Linalool a soft, sweet floral note. A supporting pair of Bisabolol and Menthol rounds out its citrus, earthy, kush and sweet character with chamomile-soft and cool, minty undertones.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. Alien Technology x Do-Si-Dos is a steady, moderate 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
Alien Technology x Do-Si-Dos builds a heavy coat of resin, so its trim is well 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 earthy, kushy 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 Alien Technology x Do-Si-Dos
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 citrus, earthy and kushy 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 sweet citrus and deep, earthy kush really come together, and it is the step most growers rush.
