Strawberries

Evidence homeCrop Overview · Growing Zones

Strawberry-specific crop notes stay here; shared crop counts, active-control status, vision context, and stress panels live on the crop overview pages.

Perennial everbearing — plant once, harvest for months. Strawberries occupy hydroponic positions semi-permanently (6-12 months) and produce continuously once established. High-value crop: greenhouse strawberries in winter are luxury produce.

Optimal Conditions

ParameterRangeNotes
Day temperature65-75°FFruit quality drops above 85°F
Night temperature55-60°FCool nights improve sweetness
VPD0.8-1.0 kPaPrefers moderate humidity
DLI17-22 mol/m²/dNeeds more light than lettuce. Grow lights critical in winter.
pH (hydro)5.5-6.2Iron availability is pH-sensitive
EC1.0-1.5 mS/cmModerate feeder, sensitive to salt buildup

Varieties for This Greenhouse

VarietyTypeSeasonFlavorRunner ProductionNotes
AlbionEverbearingYear-roundExcellentLowBest flavor of everbearing types.
SeascapeEverbearingYear-roundGoodModerateHigh yield, reliable
San AndreasEverbearingYear-roundVery goodLowGood disease resistance
MontereyEverbearingYear-roundGoodModerateHighest yield of everbearing
Recommendation: Albion. Best flavor, low runner production (important in hydro — runners are wasted energy), and consistently rated as the top everbearing strawberry for controlled environments.

Zone Recommendation

Primary: East Zone hydroponic system Strawberries need the east zone’s cooler temperatures. On hot days:

  • East peaks at ~91°F (tolerable for short periods)
  • South peaks at 100°F+ (fruit quality suffers significantly)
FactorEast ZoneStrawberry Need
Peak temp~91°F< 85°F preferred, < 95°F tolerable
Night temp~62-67°F55-60°F ideal (slightly warmer than ideal)
HumidityHigher (hydro evaporation)Prefers moderate humidity
Light14× grow lights directly overhead17-22 mol DLI target achievable

Summer challenge: June-July peak heat will stress strawberry fruit quality even in the east zone. Climate Control explains the shade and cooling tradeoff for the whole greenhouse.

Hydroponic Growing Notes

  • Bare-root starts: Soak roots 1 hour, trim to 4-5 inches, place in rockwool/clay pellets with crown above media line.
  • Position allocation: Reserve 6-10 positions. Semi-permanent — plan around them.
  • Runner management: Trim runners to direct energy to fruit production.
  • Pollination: Strawberries need pollination. Hand pollination is necessary — brush each flower with a small paintbrush. Takes 30 seconds per plant every other day.
  • Iron supplementation: Strawberries are iron-hungry. Watch for interveinal chlorosis.

Harvest & Economics

MetricValue
Days to first fruit60-90 from bare-root
Production period6-12 months continuous
Yield per plant0.5-1.0 lb per month (established)
Grocery priceUSD 4-6/lb (conventional), USD 6-8/lb (organic)
Value per positionUSD 2-6/month
At 8 positions producing 0.75 lb/month each at USD 5/lb average, that’s USD 30/month in grocery-equivalent strawberries. Year-round greenhouse strawberries in Colorado winter are a genuine luxury.

Longmont-Specific Notes

  • Altitude advantage: Cooler high-elevation nights can improve fruit sweetness.
  • Pest watch: Spider mites love strawberries AND dry air. Regular scouting of leaf undersides is essential. See Crops overview.
  • Water quality: Longmont’s low-mineral water is ideal for strawberry hydro.
