Banana Kush is a Ghost OG x Skunk Haze hybrid that flowers in roughly 8 to 9 weeks, feeds heavily, yields well indoors and rewards a slow dry and cure. It is a moderately demanding plant: dense, OG-style buds that need airflow, steady humidity control and disciplined feeding. Before any of that, a Canadian grower has to settle a legal question, because the right to grow at home depends on the province. This guide covers the law, the plant's reported traits, and each stage from seedling to jar.
TL;DR
- Federal law allows up to four plants per household, but provinces and municipalities can restrict this further, and Quebec prohibits personal cultivation.
- Banana Kush is reported at 18 to 25% THC, with 8 to 9 weeks of flowering and an indoor yield of 400 to 500 g/m².
- It is a heavy feeder, so plan nitrogen-rich vegetative feeding, CalMag under LEDs, and a lower-nitrogen, higher-phosphorus and potassium bloom.
- Dense buds invite powdery mildew and bud rot, so airflow, pruning and late-flower humidity of about 40% matter most.
- A slow dry and a cure of at least four weeks protect the banana-like aroma.

Check the rules where you live first
Under federal law, adults of legal age can grow a maximum of four cannabis plants per household, subject to provincial, territorial and municipal restrictions, according to Health Canada. The same page allows sharing up to 30 grams of personally grown cannabis with other adults of legal age. Provinces and territories may add their own measures, including lowering the number of plants per residence, and municipalities can regulate use locally through bylaws, as the Canadian Centre on Substance Use and Addiction explains.
Three examples show how much the answer varies:
- Quebec: the Cannabis Regulation Act prohibits growing cannabis plants for personal purposes. In Murray-Hall v. Quebec, 2023 SCC 10, decided on April 14, 2023, the Supreme Court of Canada unanimously upheld that ban, and violations carry fines of $250 to $750. Our separate guide to growing cannabis in Quebec covers the law, medical permits and timing.
- Manitoba: since May 1, 2025, people 19 and older may grow up to four plants per household, and the plants must be indoors and out of reach of young people.
- Saskatchewan: landlords may set reasonable rules against growing in a rental unit, and condominium boards can pass bylaws, as the University of Saskatchewan's gardening guide notes.
Renters and condo owners should read their lease or bylaws as well as provincial law. The rest of this guide applies where home cultivation is permitted.
What Banana Kush is, and what to expect from it
Banana Kush is described as a hybrid of Ghost OG and Skunk Haze, a cross Leafly's strain profile lists with limonene as the most abundant terpene, followed by myrcene and caryophyllene. Prime Cuts Nursery credits Crockett Family Farms (Dave Crockett) as the breeder and reports a 60% indica, 40% sativa balance, THC of 18 to 25%, moderate growing difficulty and a medium stretch of 3 to 5 feet indoors.
The figures that matter for planning are these:
| Trait | Reported figure | Source |
|---|---|---|
| Genetics | Ghost OG x Skunk Haze | Leafly, Prime Cuts |
| Flowering time | 8 to 9 weeks | Prime Cuts, Leafly grow guide |
| Indoor yield | 400 to 500 g/m² | Prime Cuts |
| Outdoor yield | 500 to 600 g per plant | Prime Cuts |
| Indoor height | 3 to 5 ft | Prime Cuts |
| Preferred temperature | 68 to 80°F (20 to 27°C) | Leafly grow guide |
Treat these as typical, not guaranteed. Phenotype, pot size, light intensity and training all move the result, and the Leafly grow guide itself places yield at moderate to high rather than at a fixed number.
In practical terms, Banana Kush suits a grower who has already finished one or two simple runs. A first-timer can certainly manage it, but the plant's appetite and its mold susceptibility leave less room for error than a forgiving beginner variety. Readers still choosing a first plant can start with our list of top strains for first-time growers.
Choosing a space: indoor first, outdoor with caution
The four-plant limit changes how a Canadian grower should think about space. With so few plants, each one has to earn its place, and a controlled environment gives the most predictable result. The University of Saskatchewan guide points out that indoor growing gives far more control and lists two practical questions: can the space be kept fully dark for 12 uninterrupted hours, and can you handle the smell? Cannabis is very fragrant, and without ventilation or filtration it is noticeable.
For Banana Kush specifically:
- Height: a 3 to 5 foot stretch means a tent or room with real vertical clearance, measured from pot rim to light.
- Temperature: Leafly's guide puts the best range at 68 to 80°F, which is about 20 to 27°C. Canadian basements and garages in winter often fall below that, so a small heater and a thermometer in the canopy are worth having.
- Airflow: dense buds need a gentle fan moving air through the canopy, not only an exhaust fan.
Outdoors, the reported yield of 500 to 600 g per plant is attractive, but a late-flowering, mildew-prone plant in a damp Canadian autumn is a gamble. If you grow outside where the law allows it, choose the sunniest, best-ventilated spot and be ready to manage humidity late in the season. For starter equipment, our Canada grow supplies guide lays out what a first setup needs.
Germination and the seedling stage
Germination for this strain is the same as for any other, so the details live elsewhere. The University of Saskatchewan's germination guide reports that seeds germinate best between 23°C and 27°C, with the medium kept as moist as a damp sponge. Most healthy, viable seeds sprout within two to seven days, and light is not required for germination itself. The same guide stresses that germination needs no nutrients, only clean water, and suggests distilled or reverse osmosis water if your tap water is high in dissolved solids.
If you prefer a paper towel start, our walkthrough of the 25°C paper towel test shows how to do it and what to look for in a seedling.
Once the taproot is out and the seedling is potted, keep feeding light. Banana Kush's reputation as a heavy feeder applies to established plants, not to a two-leaf seedling, and overfeeding early is a common way to stall a promising start.
Vegetative growth: training for an even canopy
The plant stretches moderately and builds thick, heavy colas, so the goal in veg is an even, open canopy. Prime Cuts Nursery suggests these steps:
- Top once at the 4th to 5th node.
- Use low-stress training to spread the branches sideways.
- Consider a screen of green (SCROG), which it calls the ideal method, with the screen set about 20 inches above the pot and branches tucked beneath it.
- Lollipop the lower growth in the first one to two weeks of flower.
- Avoid super-cropping in late flower, because dense buds can trap moisture at stress points.
Leafly's Banana Kush grow tips agree on the principle: prune and train, keep air moving through the canopy, and support the colas as they swell.
With only four plants allowed per household, a trained canopy is a way to raise yield without raising plant count. Light penetration is the point of every technique above, so judge each cut by whether it lets more light reach lower branches.
Feeding and pH
This is where Banana Kush differs most from gentler plants. According to Prime Cuts, it is a heavy feeder that handles an aggressive nitrogen-led regimen in veg, roughly a 3-1-2 NPK ratio. The same source gives these working targets:
| Medium | pH target |
|---|---|
| Soil | 6.0 to 7.0 |
| Coco | 5.5 to 6.5 |
| Hydro | 5.5 to 6.5 |
Further points from that guide:
- Add a CalMag supplement under LEDs or in coco.
- Cut nitrogen at the flip to flower and raise phosphorus and potassium, using a high P-K bloom formula.
- In hydro, keep EC between 1.3 and 2.0.
- Flush with plain, pH-adjusted water for the final 7 to 14 days in soil, or 3 to 5 days in hydro.
Leafly adds that the plant benefits from micronutrients, which also help keep powdery mildew out of the garden. Be aware that other grow guides call the nutrient needs moderate, so start below the full recommended dose and raise it as the leaves show they can take it. Dark, glossy leaves that stay flat are a good sign; clawing tips or burnt edges mean pull back.
When leaves yellow or spot, identify the cause before changing everything at once. Our guide to cannabis deficiencies helps separate a true deficiency from lockout caused by pH drift.
Flowering: humidity, mold and pests
Once the lights go to 12 hours, Banana Kush needs 8 to 9 weeks. The danger in these weeks is moisture. Leafly recommends humidity of around 40% during flowering to protect against mold, and Prime Cuts warns that the dense, OG-style flowers hold water.
Powdery mildew
The British Columbia government's integrated pest management manual describes powdery mildew as small white spots on leaf surfaces that can spread into a powdery white growth. Prevention includes avoiding excess nitrogen, spacing and pruning for airflow and light, and removing infected material. That ties directly to feeding: an over-fertilized Banana Kush is more likely to get it.
Bud rot
The same manual says bud rot develops under high humidity. Sugar leaves turn yellow and wilt, and buds turn brown and may grow fuzzy grey mold. It recommends avoiding overhead watering, spacing plants for airflow, and not over-fertilizing. Inspect the inside of the thickest colas every few days from week 5 on, and remove any affected bud completely.
Spider mites
Spider mites cause stippling, yellowing or bronzing and fine webbing, so check the undersides of leaves. The manual's advice on timing is important: pest control should be finished before flowering, because pests and beneficial insects alike get stuck in sticky trichomes during flower. Foliar sprays can also leave residues on the final product or change the flavour, and water-based sprays can create the damp conditions fungus likes. Scout weekly in veg, deal with problems early, and avoid spraying in bloom.
Nanners
Stress or genetics can produce mixed-sex flowers, often called "nanners", from the middle of buds. Heat, light leaks during the dark period and rough handling are the usual stressors. Starting from feminized seed lowers the odds of male plants but does not remove stress-driven flowers, so keep the dark period truly dark and check bud sites weekly.
Harvest, drying and curing
Prime Cuts recommends harvesting when 50 to 70% of trichomes are milky and 20 to 30% are amber, noting that more amber is associated with sedative effects. Check with a jeweler's loupe on several buds from different parts of the plant.
The banana note is the reason many growers choose this strain, and it is easy to lose. The same source says a rushed dry loses the signature flavor, because the volatile terpenes behind the banana character evaporate at high temperatures or low humidity. Its schedule is:
- Hang the plants at 60 to 65°F (about 16 to 18°C) and 45 to 55% relative humidity, in darkness, for 7 to 10 days.
- Move the buds to jars and cure for a minimum of 4 weeks.
- Open the jars daily at first to release moisture, known as burping.
Patience here is worth more than any additive. A short cure can leave a flat, hay-like smell where the fruit should be.
Our perspective: why the seed decision comes first
Most Banana Kush trouble starts before the seed goes in the ground. When the law caps a household at four plants, or bans home growing altogether as in Quebec, every plant carries a large share of the harvest, and that makes the quality of the genetics matter far more than it would in a large garden.
This is why we build our catalog around seeds suited to Canadian conditions and back it with a germination guarantee. Feminized seeds remove the guesswork of sexing plants when each slot counts. Autoflowers suit growers with short seasons or small spaces, and fast versions shorten photoperiod timelines. Our comparison of photoperiod, autoflower and fast version strains helps match each type to a real grow room.
Growing guides for strains like Banana Kush share a theme: dense flowers reward airflow, restraint with nitrogen, and a patient cure. Our support team works from that practical view of Canadian homes, where winter basements run cold and damp autumns threaten outdoor plants. Our OG Kush and Wedding Cake grow guides apply the same logic to other dense, OG-influenced plants.

FAQ
How long does Banana Kush take to grow from seed to harvest?
Flowering alone takes 8 to 9 weeks, according to Prime Cuts Nursery and Leafly. Add a few days for germination and several weeks of vegetative growth, which you control by when you switch the lights to 12 hours. Drying takes another 7 to 10 days, followed by at least four weeks of curing.
Is Banana Kush hard to grow?
Prime Cuts rates it moderate. It handles training well and rewards a good feeding schedule, but its dense buds are prone to mildew and bud rot if humidity climbs. Growers who can control airflow and humidity generally find it manageable.
Can I grow Banana Kush in Quebec?
Quebec law prohibits growing cannabis for personal purposes, and the Supreme Court of Canada upheld that ban in 2023. Our guide to growing cannabis in Quebec covers the law and the medical permit question. In provinces such as Manitoba, home cultivation is permitted under set conditions, including indoor growing only.
How many Banana Kush plants can I grow at home?
Federal law sets a maximum of four plants per household, and provinces, territories and municipalities can set stricter limits. The figure applies to the whole household, not to each adult living in it.
