Mona Lisa Cannabis Seeds by T.H. Seeds
Mona Lisa T.H. Seeds is a feminised cannabis seed that crosses Black Apple with London Pound Cake 75 and Kushmints 11 — three parent strains that bring deep colour, dessert-sweet flavour, and frosty resin production to the table. The result is a sativa-dominant hybrid that flowers in 9 weeks and yields 550–650 g/m² indoors without demanding much fuss along the way. If you want to buy a strain that looks as good as it smokes, Mona Lisa T.H. Seeds is where you start.
Pack Sizes
| Pack | Seeds | SKU |
|---|---|---|
| 3-pack | 3 feminised seeds | CSTS0087 |
| 6-pack | 6 feminised seeds | CSTS0067 |
Go with the 3-pack if you want to run a single pheno hunt or fill a small tent. Order the 6-pack if you want room to select the best mother and still have spares — the per-seed cost drops noticeably.
Mona Lisa Genetics and Lineage
Mona Lisa T.H. Seeds draws its genetic backbone from Black Apple — a dark, resinous cultivar that passes on deep purple-to-black hues and dense bud structure. T.H. Seeds crossed it with London Pound Cake 75, a strain famous for its bakery-sweet terpene profile, and Kushmints 11, which layers in a cool mint finish and extra trichome coverage. The combination produces plants that colour up beautifully in the final weeks of flower, with calyxes that look like they've been dipped in sugar.
T.H. Seeds has been operating out of Amsterdam since 1993 and we've stocked their genetics for years. They're one of those seed banks that doesn't chase hype — they breed for flavour, resin, and structure, and Mona Lisa is a solid example of that approach. The sativa-dominant genetics keep the plant reaching upward with decent internodal spacing, which means better light penetration and less larf compared to squat, bushy indicas.
Mona Lisa Flavour and Aroma Profile
Mona Lisa T.H. Seeds delivers green candy apple up front — tart, sweet, and unmistakably fruity. Crack open a cured jar and underneath that initial hit sits a thick blueberry syrup note, almost like compote, with a refreshing mint finish on the exhale that comes straight from the Kushmints 11 parent. It's a layered profile that doesn't taste like every other cookie cross on the market, and that alone makes it worth growing if you're bored of the same old terps.
The bud structure complements the flavour nicely. Dense, resin-coated flowers with a visible trichome blanket mean the terps are locked in properly. Dry and cure these slowly — 60–65% humidity, 14 days minimum — and the mint note really sharpens up.

Running Mona Lisa in a tent? Pair it with a complete grow kit that includes lighting, ventilation, and a carbon filter — you'll want proper airflow through those dense colas to prevent mould in the final weeks. A decent set of pruning shears also helps when defoliating the lower canopy around week 3 of flower. Check out our trimming scissors and carbon filters by name in the grow accessories category.
Why Mona Lisa Seeds Deserve a Spot in Your Grow
Mona Lisa T.H. Seeds is one of the most balanced feminised strains in the current T.H. Seeds catalogue, combining manageable height, fast flowering, and genuinely complex flavour. We'd pick it over a lot of the trendy US genetics floating around right now, and here's why: it's genuinely easy to grow. The 110–160 cm height range means it stays manageable in a standard 120 cm tent without aggressive training. You can top it once, maybe twice, and let it do its thing. The 9-week flowering window is honest — T.H. Seeds doesn't undercount their flower times the way some breeders do. By day 63 you should see mostly cloudy trichomes with a few amber heads, which is the sweet spot for this strain.
The yield is properly impressive too. At 550–650 g/m² indoors, you're looking at returns that rival dedicated commercial strains, but with a flavour profile that's miles more interesting than a generic Gelato cross. Outdoor growers in southern European climates should see similar numbers, though you'll want to watch for humidity in October if you're further north — those dense buds can trap moisture.
The one honest limitation: the sativa-lean means Mona Lisa can stretch noticeably in the first two weeks of flower. If your vertical space is tight, flip to 12/12 a bit earlier than you normally would. A SCROG net at about 40 cm above the pot rim catches the stretch nicely and evens out the canopy.
How to Grow Mona Lisa Cannabis Seeds
Growing Mona Lisa T.H. Seeds from seed to harvest takes roughly 13–14 weeks total, including a 4–5 week veg period and 9 weeks of flower. Follow these steps for the best results:
- Germinate your Mona Lisa seeds using the paper towel method or directly in a starter plug. Keep the temperature at 22–26°C and expect taproots within 24–72 hours.
- Transplant seedlings into their final containers once they've developed 2–3 sets of true leaves. Mona Lisa does well in 11–15 litre pots for indoor grows.
- Veg for 4–5 weeks under 18/6 lighting. Top the main stem above the 4th or 5th node to encourage lateral branching and an even canopy.
- Flip to 12/12 when plants reach roughly 50–60% of your available vertical space. Expect a stretch of 1.5–2x during the first two weeks of flower.
- Defoliate lightly around week 3 of flower — remove large fan leaves blocking bud sites, but don't strip the plant bare. Mona Lisa's structure handles light well with minimal intervention.
- Maintain relative humidity below 50% from week 5 onward. The dense, resin-heavy buds can develop bud rot if airflow is poor.
- Harvest at 9 weeks of flower when trichomes show mostly cloudy heads with roughly 10–15% amber. Dry at 18–20°C and 60% humidity for 10–14 days, then cure in sealed jars for at least two weeks.
Mona Lisa vs. Other T.H. Seeds Strains
Mona Lisa T.H. Seeds sits between the heavier indicas and longer-flowering sativas in the T.H. Seeds lineup. If you've grown other T.H. Seeds genetics, here's how it compares. Their French Macaron leans heavier on the indica side with a shorter, bushier structure — easier to manage in tight spaces but without the same flavour complexity. Underdawg OG is another popular choice from the same breeder, offering more of a classic OG fuel profile but with a longer 10-week flower time and slightly lower yields. Mona Lisa sits in the middle: manageable height, fast flower, and a flavour that's genuinely different from anything else in the T.H. Seeds catalogue.
Compared to London Pound Cake seeds from other breeders, Mona Lisa adds the minty Kushmints dimension and the dark colouring from Black Apple. You lose a bit of the pure bakery sweetness but gain a more complex, multi-layered smoke. For growers who want something that photographs well and tastes unique, Mona Lisa T.H. Seeds is the better pick. You can buy both the 3-pack and 6-pack through our seed shop.
Harm Reduction and Responsible Use
According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), cannabis strains in the 18–22% THC range are considered high-potency by current European standards. If you are new to high-THC cultivars, start with a small amount and wait before consuming more. The EMCDDA's annual European Drug Report provides further context on potency trends across the continent. Always store cannabis seeds and products away from minors.
Frequently Asked Questions
What does Mona Lisa cannabis taste like?
Green candy apple and blueberry syrup dominate, with a refreshing mint finish on the exhale from the Kushmints 11 genetics. It's a sweet, layered profile that's noticeably different from standard cookie or cake crosses.
How long does Mona Lisa take to flower?
Nine weeks from the flip to 12/12. T.H. Seeds is generally accurate with their flower time estimates. Check trichomes around day 60 — mostly cloudy with some amber is the target.
Is Mona Lisa suitable for beginner growers?
Yes. The plant stays between 110–160 cm, responds well to basic topping, and doesn't need heavy feeding or complicated training. The main thing to watch is the stretch in early flower — flip a bit early if your tent is on the shorter side.
What yield can I expect from Mona Lisa indoors?
T.H. Seeds lists 550–650 g/m², which is achievable under a decent LED in 11–15 litre pots. You'll hit the upper end of that range with a SCROG setup and proper defoliation.
Can I grow Mona Lisa outdoors?
Absolutely. It handles outdoor environments well and offers similar yields to indoor grows. In northern European climates, harvest timing in October can overlap with wet weather, so keep an eye on humidity around those dense buds.
What is the THC content of Mona Lisa?
Between 18–22% THC depending on phenotype and growing conditions. That's a solid middle-to-upper range — enough potency to satisfy experienced consumers without being overwhelming.
Does Mona Lisa need special nutrients or feeding?
Nothing out of the ordinary. A standard cannabis feeding schedule works fine. The plant isn't particularly hungry, so don't overdo the nitrogen in veg or you'll get excessive leaf growth at the expense of bud sites.
Where can I buy Mona Lisa T.H. Seeds?
You can buy Mona Lisa T.H. Seeds in 3-pack and 6-pack options through the Azarius seed shop. Both packs contain feminised seeds ready for germination.
