Autoflower Seed Bundle
Fast Flowering Pack
Three autoflowering strains selected for their speed and efficiency. From seed to harvest in as little as 8–10 weeks, these strains let you run multiple cycles per year without sacrificing quality or yield.
Before you buy
These autoflowers may finish at different times
Critical Fast Bud is typically the quickest, followed by AK-47 Auto, while Amnesia Haze Auto may take longer. If a closer harvest window matters, consider starting the slower strain first — but expect plant-to-plant variation.

Figures published by Royal Queen Seeds
Cultivation figures above are as published by the seed banks named, not measurements of our own stock. Flowering times move with light, feed and temperature, and any strain finishes across a spread rather than on a date. Figures last reviewed .
Growing the Fast Flowering Pack
A plan for these three specifically, worked out from the figures published above rather than from general advice about growing cannabis.
Starting order
Autoflowers begin flowering on their own schedule from germination, so the day you sow decides roughly when each one finishes. Sown together, they should finish in the order their published figures suggest — Critical Fast Bud Auto first, Amnesia Haze Auto last. If you would rather they came in closer together, starting the slower one first is worth considering, though plant-to-plant variation makes it an imprecise lever rather than a setting.
Light schedule
Yes — autoflowers, no light change needed. All three flower on their own without a change in day length, so one long schedule runs from germination to harvest and never changes. That also means a plant finishing early can be pulled without disturbing the other two.
Canopy management
Close — all compact. This is the easy case — an even canopy needs little intervention, and light reaches all three at roughly the same distance. Training here is a choice about yield rather than a fix for a height mismatch.
Expected harvest spread
Roughly 2–3 weeks, on the published figures: Critical Fast Bud Auto, AK-47 Auto and Amnesia Haze Auto, in that order. Plan to harvest in stages rather than clearing the space in one go, and expect the plants themselves to shift that order by a few days either way.
Questions about this bundle
Answered for the Fast Flowering Pack rather than for bundles in general.
- Can I grow all three Fast Flowering Pack strains together?
- Yes. Yes — autoflowers, no light change needed, so one timer covers all three. One space, or a staggered start works.
- Which of the three finishes first?
- On the figures published for each strain, Critical Fast Bud Auto, AK-47 Auto and Amnesia Haze Auto — in that order, across roughly 2–3 weeks. Individual plants shift that by a few days either way, so judge ripeness on the plant rather than on a date.
- How tall do these grow?
- Close — all compact. Each strain's published height is listed beside it further down this page, with the seed bank that published it named. Those figures describe untrained plants grown out by the seed bank — topping or training changes them substantially, and so does pot size.
- How many seeds are in the Fast Flowering Pack?
- Nine feminized autoflowering seeds in total — three each of Critical Fast Bud Auto, AK-47 Auto and Amnesia Haze Auto. Every one of them is sold individually on this site at the same quality; the bundle changes the price, not the seed.
- Can I make these three finish on the same day?
- Not reliably. Sowing the slower strain first shifts the finishing dates closer together, but autoflowers vary from plant to plant even within a strain, so treat it as narrowing the spread rather than removing it.
