Short outdoor seasons and quick turnovers need cuts that finish fast. Each clone here has an explicitly documented flowering window whose stated range averages 60 days or less — shown verbatim on every card, no rounding up.
Ranges vary by cut (for example 56–63 days); the number on the card is the exact range from its record, not an average across the collection.
How this collection is built
Membership requires an explicit flowering window stated in the catalog record whose midpoint is 60 days or less — e.g. “56–63 days.” Each card shows the exact stated range; ranges running past 60 days on the top end still qualify because they average at or under it. No estimate is invented when a range is not stated.
