How to Grow CBD Stephen Hawking Kush
CBD Stephen Hawking Kush is an indica-dominant strain (60% indica) bred to lead with CBD rather than THC, a cross of Harle-Tsu and Sin City Kush. It carries a 10 to 13% CBD level, a sweet berry and blueberry flavor over an earthy base, and a happy, munchie-inducing and relaxed effect. As a feminized strain it grows into all-female plants, so every seed can go straight to flower with no males to sort out. This guide walks you through the whole grow, from germinating the seeds to the final cure.
It reaches a manageable 1.5 m, flowers in a quick 7 to 9 weeks, and finishes outdoors in September with a medium yield. Because it is beginner-friendly and leads with CBD, it is an easy, forgiving plant for a first grow, and its sweet berry, Kush-backed character is a big part of its appeal.

How to Germinate CBD Stephen Hawking Kush Seeds
A healthy harvest starts at germination. The paper towel method is hard to beat: fold the CBD Stephen Hawking Kush 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, forgiving genetics make for a strong seedling that is easy to get going, even on a first grow.
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 CBD Stephen Hawking Kush in the Vegetative Stage
As a photoperiod plant, you control the veg stage with the light schedule. Keep CBD Stephen Hawking Kush 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 60% indica with Kush in its background it grows into a sturdy, bushy plant, settling around 1.5 m.
This is the stage to shape the plant. Topping early and using low-stress training to spread the lower branches opens up the canopy, improves airflow, and encourages even colas. Give it room so light reaches the inner buds. Because it is a forgiving, beginner-friendly plant, it bounces back well if your timing or training is not perfect.
Flowering and Buds of CBD Stephen Hawking Kush
Indoors, flip CBD Stephen Hawking Kush to a 12/12 light cycle to trigger flowering, which runs a quick 7 to 9 weeks. Outdoors it ripens early, in September. As an indica-dominant Kush it fills out with compact, chunky colas, and it gives a steady medium yield, a touch more generous outdoors.
Through bloom, drop humidity to 40 to 45% and keep air moving so the dense buds stay dry and mold-free. The flowers build a sweet, fruity aroma, ripe berry and blueberry over an earthy, woody base.
Its 10 to 13% CBD level is what sets CBD Stephen Hawking Kush apart. Because it is bred to express CBD rather than THC, the experience stays mild and clear-headed, a happy, relaxed and munchie-inducing feel without an overwhelming punch, which is exactly why many growers choose a CBD-rich variety like this one.
Common Problems and Pro Tips
CBD Stephen Hawking Kush is a forgiving, beginner-friendly grow, but its compact indica buds and sweet aroma still point to a few things worth watching.
- Protect the dense buds: chunky Kush colas can trap moisture, so keep humidity down and air moving in late flower to avoid mold.
- Do not overfeed: as an easy plant it does not demand heavy feeding, so build nutrients up slowly and let the plant tell you when it wants more.
- Watch the early finish: it ripens fast and early outdoors, so check trichomes from late summer rather than waiting for a mid-fall harvest.
Expert tip: this is a quick, early finisher, so a clean, slow dry and cure matters even more. Take your time after the chop so the sweet berry and earthy notes hold up.
Aroma, Flavor and Effects
The nose is sweet and fruity: ripe berry and blueberry up front with a hint of cherry, all grounded by an earthy, woody base. It leans rich and dessert-like rather than sharp, a profile that matches its easygoing, clear-headed character.
The flavor follows the nose, sweet berry and blueberry over earthy wood on the exhale. On the effect side it is happy, relaxed and munchie-inducing, a gentle, mellow feel grounded by its indica body. Because CBD Stephen Hawking Kush leads with CBD rather than THC, the overall experience stays mild and easy to enjoy.
Dominant terpenes
CBD Stephen Hawking Kush carries a short, focused terpene profile built on two main players. Myrcene brings an earthy, herbal base with a ripe, fruity edge, the backbone behind its sweet berry and blueberry character. Alpha-Pinene adds a sharp, fresh pine note that drives the woody, earthy side of the aroma. Together they frame the berry, blueberry, cherry, earthy and woody profile the strain is known for, a rich and grounded character rather than a sharp, citrus one.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. As an easy, moderate feeder CBD Stephen Hawking Kush does not need to be pushed hard, 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
CBD Stephen Hawking Kush builds a decent 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 sweet berry 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 CBD Stephen Hawking Kush
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 7 to 9 weeks after the flip, and outdoors the plants are ready early, in September.
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 sweet berry and earthy 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 ripe berry and woody depth really come together, and it is the step most growers rush.
