Time From Seed To Smoke
Use this calculator to estimate how long it will take to grow a smokable product.
All fields are required for an accurate estimate.
How does this calculator work?
Our Time From Seed to Smoke Calculator uses your chosen strain type (indica, sativa, hybrid, or autoflower), starting method (seed or clone), preferred vegetative period, and curing duration to calculate how long your cannabis grow might take. It combines average timelines for germination or cloning, vegetative growth, flowering, and curing—giving you a minimum, average, and maximum range.

What does “seed to smoke” mean?
“Seed to smoke” refers to the full lifecycle of your cannabis plant—from the moment you plant a seed or acquire a clone to when you finally harvest, dry, cure, and smoke your buds.

How long does it take to grow weed indoors?
Grow times vary depending on genetics, environmental controls, and grower skill. Typically, indica strains flower faster (7–9 weeks), while sativa strains can take 9–12 weeks or longer. Factoring in time for germination/cloning, vegetative growth, and curing, indoor grows often span 3–6+ months.

How long does it take from seed to smoke?
That’s exactly what our calculator estimates. By plugging in your strain type, vegetative stage duration, and curing time, you’ll see approximate days and months until your cannabis is ready to smoke.

How should I use the seed-to-smoke calculator?
Enter each required field—plant type, whether you start from seed or clone, your planned veg time, and desired curing time. The calculator shows a minimum, average, and maximum grow cycle. You can experiment with different inputs (e.g., extending veg time) to see how it affects your total timeline.
While the calculator offers a solid estimate, always watch your plants for the best harvest timing. For real-world tips, join our expert-led forums at SativaUniversity.com.
Why does the calculator show a range of times?
No two cannabis plants grow identically. Differences in strain genetics, environmental conditions, and nutrient regimens can lead to faster or slower development. The calculator provides minimum, average, and maximum estimates to give you a range of possibilities.

How does the strain I choose affect the grow cycle length?
In general:
– Indica strains often finish faster (7–9 weeks of flowering).
– Sativa strains take longer to mature (9–12+ weeks).
– Hybrids usually sit somewhere in the middle.
– Autoflowers don’t rely on light cycles and may complete their lifecycle quicker overall.
Our calculator’s timeline adjusts based on strain selection. However, always check the breeder’s recommended flowering period for your specific seeds or clones.
