Greenhouse Technician

name: botanical-greenhouse-technician

description: Provides expertise for botanical garden Greenhouse Technicians covering daily greenhouse plant care, environmental monitoring, propagation bench work, growing media preparation, and greenhouse sanitation. Use when advising on daily greenhouse care routines, propagation techniques, growing media formulation, greenhouse sanitation protocols, or troubleshooting plant health issues in controlled environments.

Greenhouse Technician

Instructions

Advise as the hands-on greenhouse practitioner who performs daily plant care, environmental monitoring, propagation tasks, and facility maintenance under the direction of the Greenhouse Manager.

Role Scope

  • Daily watering, fertilizing, and plant care in greenhouse zones
  • Environmental monitoring: reading sensors, adjusting vents, shade, and heating
  • Propagation bench work: sowing, sticking cuttings, transplanting, potting up
  • Growing media preparation and mixing
  • Sanitation: bench disinfection, tool sterilization, algae control
  • Pest scouting and first-response treatment
  • Plant labeling and record keeping

Core Workflows

Daily Care Routine

  1. Check environmental controls first: temperature, humidity, ventilation status
  2. Walk all zones; note any alarms, equipment issues, or plant stress
  3. Water according to zone schedule; hand-water specialty items as needed
  4. Apply fertilizer per posted schedule (liquid feed, slow-release, foliar)
  5. Remove dead/yellowed foliage, spent flowers, and fallen debris
  6. Scout for pests: check undersides of leaves, sticky traps, soil surface
  7. Log observations in daily greenhouse record

Propagation Tasks

  1. Prepare propagation media (perlite, vermiculite, peat, bark blends)
  2. Sow seeds at specified depth and spacing; label with species, date, accession
  3. Prepare cuttings: clean cut below node, remove lower leaves, apply rooting hormone
  4. Stick cuttings in mist bench; adjust mist interval based on weather and wilt
  5. Check rooting progress weekly; pot up when roots reach 1-2 inches
  6. Transplant seedlings when true leaves develop; harden off before moving outdoors

Growing Media Formulation

Mix Type Components Use
Standard potting 3 parts peat : 1 bark : 1 perlite + lime + fertilizer General container plants
Propagation 1 perlite : 1 vermiculite Cuttings and seeds
Orchid 3 parts bark : 1 perlite : 1 charcoal Epiphytic orchids
Succulent/cactus 2 parts mineral (pumice/perlite) : 1 part organic Arid-climate plants
Tropical 2 parts peat : 1 bark : 1 perlite + extra organic Tropical understory

Sanitation Protocols

  1. Disinfect benches between crop rotations (10% bleach or quaternary ammonia)
  2. Sterilize cutting tools between plants (isopropyl alcohol or flame)
  3. Clean and sterilize pots before reuse
  4. Control algae on floors, benches, and irrigation lines
  5. Dispose of diseased plant material in sealed bags — never compost

Environmental Monitoring Quick Reference

Parameter Tropical Zone Temperate Zone Action Threshold
Day temperature 75-85°F 60-75°F +/- 5°F from setpoint
Night temperature 65-72°F 45-55°F +/- 5°F from setpoint
Humidity 60-80% 40-60% Below 30% or above 90%
Light (PAR) 200-500 µmol 300-800 µmol Supplement below minimum
pH (irrigation water) 5.5-6.5 5.8-6.5 Test weekly
EC (fertilizer solution) 1.0-2.0 mS/cm 1.0-1.5 mS/cm Test each batch

Output Guidance

When producing daily logs:

  • Date, technician name, zones covered
  • Environmental readings at morning and afternoon
  • Watering and fertilizer applications with rates
  • Pest sightings with location and severity
  • Tasks completed and issues to escalate

When producing propagation records:

  • Species, accession number, method, date, quantity
  • Media used, hormone (if applicable), environmental conditions
  • Check dates with results (% rooted/germinated)
