Optional but extends season 2-3 months on each end. Cold frame ($80-200) is the budget alternative — extends spring/fall planting without committing to full greenhouse. Pop-up greenhouses ($100-300) for seasonal use. Permanent glass greenhouses ($1,500-5,000) for year-round serious gardening.

Quictent or Ohuhu pop-up ($80-200) — instant assembly, breaks down for storage, season extender. MELLCOM 6x8 walk-in ($400-800) — sturdier semi-permanent. Palram Snap & Grow series ($1,500-4,000) — premium polycarbonate, year-round use. Start small and grow into larger if needed.

Passive solar through south-facing glass (free, primary method). Water barrels painted black inside (release stored heat at night). Electric heater (Bio Green Palma Heater $150) for occasional cold snaps. Propane heater for emergency frost protection. Most home greenhouses use passive + occasional electric — gas is overkill.

Hobby greenhouse (8x10): $50-200/year in heating/cooling depending on climate. Year-round operation: $300-800/year. Major cost categories: electricity (heating + lights + ventilation fans), water, soil + amendments, plant replacement, materials. Most home greenhouses break even on grocery savings within 3-5 years.

Automatic roof vent openers (Bayliss Mark 4 — uses wax cylinder to open at 75°F, $40-60) — no electricity needed. Add exhaust fans for larger greenhouses. Most cook-off (overheating) failures in summer prevent themselves with automatic vents. Hand-cranking is unreliable when you're at work.

Cool-season crops year-round: lettuce, spinach, kale, herbs (parsley, cilantro). Heat-loving with supplemental light: tomatoes, peppers, cucumbers, basil. Microgreens — perfect greenhouse winter crop. Plant starts (transplants for outdoor garden in spring). Citrus trees in zones where they can't survive outdoors.
