Getting Started: Your 7-Step Action Plan

1

Choose Your Location

Select a site with 6+ hours of sunlight, level ground, and easy access to water and electricity. Consider wind protection and drainage.

Pro Tip: South-facing locations receive the most winter sun, which is crucial for year-round growing.

2

Select Your Greenhouse Type

Start with a 6×8 or 8×10 foot greenhouse for beginners. Choose polycarbonate for durability and insulation, or glass for maximum light transmission.

Budget Guide: Basic kit: $500-1500, Mid-range: $1500-3000, Premium: $3000+

3

Prepare the Foundation

Create a level foundation using concrete, gravel, or timber base. Proper foundation prevents settling and ensures good drainage.

Foundation Options: Concrete slab (permanent), timber frame (DIY-friendly), gravel pad (economical)

4

Install Essential Equipment

Install automatic roof vents, thermometer, and basic shelving. Add electrical supply for future heating and lighting needs.

Priority Order: Ventilation first, then temperature monitoring, followed by watering systems

5

Set Up Growing Systems

Install staging/shelving, set up containers and growing medium. Prepare seed starting area with proper drainage.

Space Maximization: Use vertical space with multi-tier shelving and hanging baskets

6

Start Small and Learn

Begin with easy crops like lettuce, herbs, and radishes. Monitor temperature and humidity daily to understand your greenhouse microclimate.

Beginner Crops: Lettuce, spinach, basil, radishes, microgreens – these are forgiving and fast-growing

7

Expand and Optimize

Once comfortable, add heating for winter growing, automate watering, and try more challenging crops like tomatoes and peppers.

Growth Path: Master environmental control → Add automation → Experiment with specialty crops

Common Challenges & Solutions

Overheating

Symptoms:

Wilted plants, excessive temperatures (>85°F), poor plant growth

Solutions:

  • • Install automatic roof vents
  • • Add side louvers for cross-ventilation
  • • Use shade cloth (30-50% shade)
  • • Install circulation fans
  • • Water early morning to cool plants

Poor Humidity Control

Symptoms:

Fungal diseases, condensation on walls, stunted growth

Solutions:

  • • Improve ventilation to reduce humidity
  • • Water at soil level, not on leaves
  • • Space plants properly for air circulation
  • • Use humidity monitoring
  • • Remove standing water

Pest Management

Common Pests:

Aphids, whiteflies, spider mites, fungus gnats

Prevention:

  • • Inspect plants regularly
  • • Quarantine new plants
  • • Use beneficial insects
  • • Keep greenhouse clean
  • • Remove infected plants promptly

Winter Cold

Issues:

Frost damage, slow growth, plant death

Winter Protection:

  • • Install greenhouse heater

  • • Add insulation (bubble wrap)
  • • Close vents at night
  • • Choose cold-hardy varieties
