10 Indica Autoflower Strains Compared
Indica autoflowers are popular with home growers because they tend to stay compact and they finish without a light change. This page compares ten indica autoflower strains from Kind Seed’s White Label line, side by side, using the numbers each product page lists. Every figure below is breeder stated: it describes potential under good conditions, not a lab result from your garden.
Kind Seed runs this site, and every strain on this list is a Kind Seed listing. We picked strains that are labeled indica autoflowers on their product pages and that have a full spec table, then grouped them by what they may suit. Home grow rules differ by state, so check your state’s home grow law before you buy seeds or start a grow.
What makes a plant an autoflower
Most cannabis is a short day plant. The University of Saskatchewan’s gardening guide, a Canadian university guide we use here for growing basics, explains that it needs “approximately 12 hours (or more) of uninterrupted darkness” to start flowering. Autoflowers are different. The same guide calls them day neutral plants that “begin to flower based on age and/or maturity, instead of the length of darkness,” and notes that many are “ready to harvest in 70-90 days.”
Oregon State University Extension, writing about hemp, reports that autoflower varieties are generally ripe around 75 days after planting, compared with about 120 days for full season types. That is a hemp finding, but it shows why autoflowers fit short seasons and quick indoor runs.
What indica means on a seed listing
Indica is a loose label. The USask guide calls indica and sativa “very large generalizations and not exact definitions.” It describes indica type plants as “short and squat” with wide leaves, dense buds and a maturity time “typically between 8 and 10 weeks,” and notes that most seeds in stores are crosses and hybrids. Read the label as a hint about plant shape, and use the stated height and timing to plan your space.

How we picked and how to choose
We included only strains that the product page labels as indica autoflowers, that are White Label, and that list height, flowering time, THC potential and yield. We did not grow these strains side by side, so this is a comparison, not a ranking.
To choose, start with your space and season:
- Headroom. If your tent is short, look at the strains listed as short.
- Time. Stated flowering times run from 7 weeks to 10 weeks.
- Yield. Yield numbers depend heavily on light and root room. Compare them across strains, but do not read them as a promise.
- Aroma. Pick from the flavor notes you enjoy most.
Kind Seed’s germination guarantee covers White Label seeds only, for orders up to 3 months old and 100 seeds or less, when you follow the published germination method at https://kindseed.com/germination-guarantee/. All ten strains on this list are White Label, according to their product pages.
How to grow indica autoflowers
- Start in the final container. The University of Georgia Extension, writing about autoflowering hemp, notes that “most autoflowering cultivars are very sensitive to any stress early in growth” and that even slight root restriction in transplant trays can trigger early flowering. Planting straight into the final pot avoids that.
- Use a pot that fits the plant. USask suggests no smaller than 5 gallons (20 liters) for autoflowers grown in containers outdoors.
- Pick a light schedule and keep it. USask notes autoflowers can be grown under any light schedule, though 18 hours on and 6 off is recommended.
- Feed lightly at first. Start below label strength and increase only if the plant shows it needs more.
- Train gently. Bend stems early instead of cutting them. Autoflowers have little time to recover from heavy stress.
- Keep air moving. Dense indica buds need airflow, especially late in flower.
- Harvest on ripeness. Use the stated time as a guide, then check the flowers and trichomes.
Troubleshooting
| Problem | Possible cause | What to do |
|---|---|---|
| Plant flowered while still tiny | Early stress or root restriction in a small cell | Start in the final pot next time and avoid transplant shock |
| Plant is taller than the listing said | Normal variation or strong light | Use low stress training and check the stated height before choosing |
| Harvest came later than the stated time | Cooler room, lower light or slow start | Use the stated time as a guide and judge by ripeness |
| Yield well below the listing | Small pot, weak light or stress | Check that pot size and light suit the plant. Yields vary, and listings are breeder stated potential |
| Leaf tips burned | Too much fertilizer | Water with plain water and cut back the feed |

They do not need a 12 hours on, 12 hours off switch to flower. The University of Saskatchewan notes they can grow under any light schedule, though 18 hours on and 6 off is recommended.
Are the THC and yield numbers guaranteed?
No. They are breeder stated potential under good conditions, not a lab result from your garden. Light, root room and care all change the outcome.
Does Kind Seed's guarantee cover these seeds?
All ten strains are White Label. Kind Seed's germination guarantee covers White Label seeds only, for orders up to 3 months old and 100 seeds or less, when you follow the published method.
