Companion-growing notes

  • Heavy uptake of nitrogen, potassium. Co-grown crops with the same demand will end up deficient even at "correct" EC.
  • Very high transpiration. Reservoir drops fast; expect daily top-ups and EC creep.

Aquaponics suitability

Not recommended

Fish waste alone doesn't supply enough of what this crop demands. Grows in hybrid systems with supplemental dosing, but expect active management.

Care notes

A specialty crop for homebrewer-aquaponics enthusiasts. The vine needs 58 m of vertical growing space (trellis, strong twine from ground to eave), which limits it to outdoor systems, tall greenhouses, or structures with high ceilings. Large container (30 L) or in-ground planting. EC 1.5-2.5 mS/cm. pH 6.0-7.5. Temperature: 1525°C growing season; requires winter dormancy with freezing temperatures. Full sun (DLI 18-25 mol/m2/day; hops need long day length, 15+ hours, to trigger cone production). Propagation by rhizome division (plant pieces of the underground rhizome in spring). First-year harvest is minimal; full production begins in year 2-3. Harvest cones in late summer when they feel papery, dry, and spring back when squeezed, and when the lupulin glands (yellow powder inside the cone) are visible and aromatic. Each mature plant produces 0.52 kg of dried cones. Dry cones at 5565°C immediately after harvest to prevent oxidation. For homebrewers, 2-3 plants provide enough hops for 10-20 batches of beer per year.

Notable varieties

CultivarTypeOriginDaysNotes
Cascade open pollinated USDA / Oregon State University, 1972 365 American aroma hop, citrus-grapefruit profile. The defining hop of West Coast IPAs. The most-planted home garden variety; vigorous, productive, disease-resistant, suits most American beer styles.
Centennial open pollinated USDA, 1990 365 American aroma-bittering dual-purpose hop. Lemon-citrus profile. Often called 'super Cascade' for the more intense character. Productive, popular among home brewers.
Willamette open pollinated USDA, 1976 365 Mild English-style aroma hop, slightly spicy-floral. The American answer to Fuggle. Good for English ales, pale lagers.
Magnum open pollinated Hüll Research Station, Germany, 1980 365 Bittering hop, high alpha acids (12-15%). Clean bitterness without strong aroma; what most commercial pale ales use for bittering. Productive.
Saaz open pollinated 365 Czech noble hop. The defining aroma hop of Bohemian Pilsner. Lower yield than American varieties but flavor irreplaceable for pilsner-style brewing.
