How to Grow Purple Bubba Kush
Purple Bubba Kush is a striking, high-THC indica famous for its deep purple buds and sweet, berry-sour flavour. It carries a potent 22–24% THC, a berry, sour and sweet taste, and a happy, relaxed, munchie-inducing effect on a tall, resinous feminized plant with pedigree West Coast genetics.
Built from Granddaddy Purple crossed with Bubba Kush, this is an 80% indica, 20% sativa feminized hybrid with a heavyweight, body-forward character. The result is a dense, frosty plant that pairs the deep purple colour and berry flavour of Granddaddy Purple with the heavy, soothing punch of Bubba Kush.

Classic Purple Indica Genetics
Purple Bubba Kush brings together two West Coast legends. From Granddaddy Purple it inherits its deep purple colour, sweet berry-grape flavour and heavy relaxation, while from Bubba Kush it gains dense, chunky, resin-coated buds and a potent, body-forward punch.
That pairing makes it both beautiful and strong. The purple and violet tones come from anthocyanin pigments on the Granddaddy Purple side, which show up most vividly when night temperatures cool late in flowering, giving the dense buds their signature purple look against a heavy frost of trichomes.
Climate and Where to Grow It
Purple Bubba Kush does well in a temperate climate with good light and steady airflow, and cooler nights late in bloom are a genuine bonus since they bring out its purple colour. It performs both outdoors in a mild season and in a controlled indoor tent, though you should plan for its height.
At around 1.7 m it grows tall for an indica, so give it vertical room or train it early. Outdoors a single plant can bring in a solid 500–600 g in a good spot, while indoors yields are more modest at 300–350 g/m². Keep humidity in check as the dense, chunky buds fill in, since tight indica flowers are worth protecting from bud rot.
Indoors, aim for daytime temperatures around 68–78°F (20–26°C), and let the dark period run a little cooler in the final weeks to deepen the purple. Keep the canopy open so light reaches the lower bud sites on this tall, resin-heavy plant.
Growing Feminized Photoperiod Seeds
As a feminized strain, every seed grows into a flowering female, so there is no need to sex the plants or remove males. That keeps the grow simple and means no wasted time or space on plants you would only cull later, which is part of why it suits newer growers so well.
Being a photoperiod plant, Purple Bubba Kush flowers on a light change rather than on age. Grow it under a long day (around 18 hours of light) through the vegetative stage, then switch to a 12/12 cycle to trigger flowering. A shorter veg helps keep this naturally tall plant more manageable before the stretch of early bloom.
Feeding Schedule (EC Guide)
This is a potent, resinous indica that sets dense buds, so feed it steadily but without overdoing it. Start low, build up as the plant asks for more, and taper off for the final flush so the sweet berry and sour flavour comes through clean and the smoke finishes smooth.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the dense buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs about 8–10 weeks. As an 80% indica it stays bushy and fills in dense, chunky, resin-coated buds that often take on deep purple and violet tones as the nights cool toward harvest, rather than stretching the way a sativa would.
Keep the canopy open so light reaches the lower flowers, and give the colas light support as they gain weight. Harvest when most trichomes have turned cloudy with a few amber heads for the fullest expression, and run a short plain-water flush in the last week or two before you cut it down.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. A slow, even dry protects both the purple colour and the sweet, berry-sour aroma, which can dull quickly if the dense buds are dried too hard or too fast.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the berry sweetness and sour edge forward and smooths the smoke, which is exactly what this high-THC purple indica deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Purple Bubba Kush is a frosty, high-THC plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of sweet, berry-forward concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Purple Bubba Kush has a sweet berry flavour with a distinct sour edge, the grape-like profile its Granddaddy Purple side is famous for. It is a fruity, moreish taste with a sharp twist rather than an earthy or chemical one, and it carries beautifully through a careful cure.
Its terpene profile is led by a few key players. Myrcene and linalool carry the sweet berry and soft floral notes; caryophyllene adds a sharp, peppery bite that brings out the sour side; and pinene lifts the whole thing with a fresh, resinous touch that keeps the sweetness from feeling heavy.
Effects and Best Use
With its heavily indica genetics, Purple Bubba Kush is reported as happy, relaxed and munchie-inducing, a mellow, body-forward character with a cheerful edge and a tendency to bring on the munchies. It leans toward evening and wind-down use, making it a classic choice for relaxing at the end of the day.
At a potent 22–24% THC it hits with real strength, so a little goes a long way, especially for less experienced users. That potency, the striking purple colour, the sweet berry-sour flavour and the forgiving, beginner-friendly nature are exactly why growers reach for Purple Bubba Kush.
FAQ
What are Purple Bubba Kush’s genetics?
Purple Bubba Kush is a feminized, heavily indica hybrid (80% indica, 20% sativa) built from Granddaddy Purple crossed with Bubba Kush. From Granddaddy Purple it takes deep purple colour and a sweet berry flavour, while Bubba Kush adds its heavy, soothing body character and dense, resinous bud structure.
Why does Purple Bubba Kush turn purple?
The purple colour comes from anthocyanin pigments in its Granddaddy Purple heritage, which show up most strongly when night temperatures drop toward the end of flowering. Letting the dark period run a little cooler in the final weeks helps bring out the deep purple tones that give the strain its name.
Is Purple Bubba Kush indica or sativa?
It is strongly indica-dominant, at roughly 80% indica and 20% sativa, which it takes from both its Granddaddy Purple and Bubba Kush parents. That shows in a relaxed, body-forward character and dense, chunky buds, with only a light touch of sativa to keep the heavy effect from feeling one-dimensional.
Is Purple Bubba Kush good for beginners?
Yes. It is a sturdy, forgiving feminized plant with no males to remove, which makes it genuinely beginner-friendly. Its main quirk is height, since it grows tall at around 1.7 m, so give it headroom or start low-stress training early, and it rewards new growers with potent, purple-tinged buds.
What does Purple Bubba Kush taste like?
Expect a sweet berry flavour with a sour edge, the grape-like profile its Granddaddy Purple side is known for. Myrcene and linalool carry the sweet berry and floral notes, caryophyllene adds a sharp, peppery bite that brings the sour side, and pinene lifts it with a fresh touch.
How long does Purple Bubba Kush take to flower?
About 8–10 weeks once you switch to a 12/12 light cycle, with outdoor plants finishing around October. It is a photoperiod feminized strain, so it blooms on the light change rather than on age, and the final weeks, with cooler nights, are when the deep purple colour develops best.
