How to Germinate Monkey OG Seeds
A big harvest starts at germination. The paper towel method is hard to beat: fold the Monkey OG 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 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 Monkey OG in the Vegetative Stage
Monkey OG likes a temperate climate and, as a 60% indica, it grows into a compact, well-branched plant that stays around 1.2 m indoors but stretches into a larger plant outdoors. Keep it on 18 hours of light a day, aim for day temperatures of 68 to 79°F, and hold humidity around 50 to 60%. Its sturdy frame makes it tidy and easy to manage.
This is the stage to shape the plant. Topping early and using low-stress training to spread the branches opens up the canopy, improves airflow, and sets up the heavy yield this strain reaches outdoors. Give it room so light reaches the lower bud sites.
Its sturdy build and October finish make it a strong outdoor plant, where its yield really opens up:
- Southern California and the Southwest: the long, warm season lets it reach its full 28 to 35 oz outdoor potential and keeps the resinous, banana-scented buds clean through October.
- Mediterranean-style climates: warm days and a long season suit its 8 to 10 week bloom and tropical profile.
- Large outdoor grows: given a big pot or open ground, its yield climbs well beyond what its compact indoor size suggests.
Flowering and Buds of Monkey OG
Indoors, flip Monkey OG to a 12/12 light cycle to trigger flowering, which runs 8 to 10 weeks. Outdoors it ripens through October. As an indica-leaning hybrid it shows a moderate stretch after the flip, then fills out with dense, resinous, banana-scented buds.
Through bloom, drop humidity to 40 to 45% and keep air moving so the flowers do not trap moisture. The buds build a sweet, tropical banana aroma over an earthy, fruity base, the signature that gives this strain its playful name.
At 23 to 26% THC it sits in the medium to high range, so the effect is noticeably potent, a creative, euphoric and happy lift backed by a relaxed indica body.
Common Problems and Pro Tips
Monkey OG is beginner-friendly, but its potency, dense buds and big outdoor yield 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.
- Plan for its outdoor size: those big yields come on a larger plant, so give it space, a big container and good support.
- Respect the potency: at up to 26% THC it is strong, so cure it well and go easy, especially for newer users.
Expert tip: this is a potent, flavorful banana strain that rewards good finishing. Train it early for an even canopy, keep airflow strong around the dense buds, and dry and cure slowly to protect that sweet, tropical banana aroma.
Aroma, Flavor and Effects
The nose is sweet and tropical: a ripe banana aroma over an earthy, fruity base, a rich, dessert-like profile that stands out from the pack. It is smooth and inviting rather than sharp, and it deepens as the buds cure.
The flavor follows the nose, sweet banana and tropical fruit with an earthy finish. On the effect side it is creative, euphoric and happy, a bright, feel-good lift backed by a relaxed indica body. Because THC runs a strong 23 to 26%, it has real punch, so a measured hand is wise.
Dominant terpenes
Monkey OG carries a deep, fruit-forward terpene profile. The most influential are Limonene, Linalool, Terpinolene, Citral, Eugenol and Terpineol: Limonene brings a bright citrus-fruit lift, Citral a sweet, zesty edge, Terpinolene a fruity, complex top note, Linalool a soft floral sweetness, Terpineol a smooth, lilac-like roundness, and Eugenol a warm, clove-like spice. Behind them sits a supporting cast, including Cedrene, Borneol, Camphene, Fenchol, Nerolidol and Phytol, which rounds out its sweet, tropical character.
Nutrient Schedule
Treat the figures below as a starting map, not a rulebook. Monkey OG is a productive feeder, especially outdoors as it builds that big yield, 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
Monkey OG builds a good coat of resin, so its fragrant trim is worth keeping. The sugar leaves you take off while manicuring carry 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 banana 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 Monkey OG
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 banana, earthy and fruity 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 banana character and tropical fruit really come forward, and it is the step most first-time growers rush.
