How long does it take to build a MONT greenhouse kit?

Most MONT (Monticello) kits require a full weekend for two people to complete. This includes site preparation, frame assembly, and panel installation. The modular design ensures that while it takes time, the process is straightforward with basic tools.

What is the benefit of 8mm polycarbonate over glass?

8mm polycarbonate is 12 times lighter than glass and virtually unbreakable. It provides superior insulation by trapping air between its walls (acting like a double-pane window), which keeps your plants warmer during freezing nights.

What makes the MONT Mojave Edition different?

The Mojave Edition is specifically engineered for hot climates. It features a solar-powered commercial exhaust fan system and tinted roof panels that reduce UV heat gain by 15-20%, keeping your plants from wilting during summer peaks.

Greenhouse Kits

Q: How do I keep my greenhouse from overheating in summer?

Proper ventilation is key. We recommend using solar-powered exhaust fans (standard in our MONT Mojave kits) and shade cloths. Opening roof vents and doors creates a 'chimney effect' that pulls cool air in and pushes hot air out.

Q: Do I need a building permit for a greenhouse kit?

In many jurisdictions, greenhouses are considered temporary structures or outbuildings and may not require a permit if they are under a certain square footage. However, we always recommend checking with your local HOA or city planning office before installation.

Greenhouse Expert Knowledge Base

Everything you need to know about year-round growing, structural integrity, and maximizing your harvest.

What is the best direction for a greenhouse to face? +

For maximum sunlight exposure in the northern hemisphere, the longest side of your greenhouse should face South. This ensures your plants receive the most consistent light throughout the day, especially during the shorter winter months.

How do I keep my greenhouse from overheating in summer? +

Proper ventilation is key. We recommend using solar-powered exhaust fans (standard in our MONT Mojave kits) and shade cloths. Opening roof vents and doors creates a "chimney effect" that pulls cool air in and pushes hot air out.

Can you grow vegetables in a greenhouse during winter? +

Yes! With 8mm twin-wall polycarbonate insulation, you can grow cool-weather crops like kale, spinach, and carrots all winter. For warm-weather crops like tomatoes, you may need a dedicated heater like the one found in our MONT MOHEAT package.

How do I manage humidity and condensation? +

High humidity can lead to mold and fungus. To prevent this, ensure constant airflow with a small circulation fan. Watering your plants in the morning rather than the evening also gives excess moisture time to evaporate before temperatures drop at night.

Do I need a building permit for a greenhouse kit? +

In many jurisdictions, greenhouses are considered "temporary structures" or "outbuildings" and may not require a permit if they are under a certain square footage. However, we always recommend checking with your local HOA or city planning office before installation.

Do greenhouses protect plants from UV scorch? +

Yes. High-quality polycarbonate panels are treated with a UV-inhibitor. This allows the "good" light for photosynthesis to pass through while blocking the harsh rays that cause leaf scorch and damage your greenhouse structure over time.

How often should I clean my greenhouse panels? +

To maintain maximum light transmission, you should clean your panels twice a year—once in early spring and once in late autumn. Use a mild soap, warm water, and a soft cloth to avoid scratching the polycarbonate.

What is the best floor for a greenhouse? +

Gravel is the most popular choice because it provides excellent drainage and helps maintain humidity. Pavers or bricks are also great for thermal mass, absorbing heat during the day and releasing it at night.

How do plants get pollinated inside a greenhouse? +

You can encourage natural pollination by leaving doors and vents open for bees. For self-pollinating plants like tomatoes, a gentle shake of the plant or the airflow from an internal fan is usually enough to move the pollen.

Is it easier to control pests in a greenhouse? +

Absolutely. A greenhouse acts as a physical barrier against deer, rabbits, and larger pests. For smaller insects like aphids, the enclosed environment allows you to use beneficial insects (like ladybugs) much more effectively than in an open garden.

As specialists in high-quality outdoor structures, we include our professional greenhouses within our larger DIY Buildings & Kits category—ensuring every sanctuary we sell meets the same rigorous standards for durability and craftsmanship.
