What size greenhouse do I need for my seedling operation?

Base your choice on how many seedlings you want to start at once—a 4x6 ft greenhouse suits home gardeners with a few dozen plants, while market growers typically need 8x12 ft or larger. Consider your available space and future expansion, since starting small limits how many crops you can manage per season.

What's the difference between heated and unheated seed trays?

Heated trays maintain soil temperature between 20-25°C, speeding up germination for heat-loving seeds like tomatoes and peppers, while unheated trays rely on ambient temperature and work fine for cool-season crops. Heated trays cost more upfront but cut germination time by days, which matters if you're running tight planting schedules.

Do I need ventilation and humidity control in a greenhouse?

Yes—seedlings need air circulation to prevent mold and damping-off disease, while humidity should stay around 70-80% during germination. Look for greenhouses with vents, fans, or automatic louvers, or plan to add them yourself if your budget is tight.

What lighting should I use for germination indoors or under glass?

LED grow lights are more energy-efficient than fluorescents and run cooler, which matters in the UAE's heat. Position lights 15-20 cm above seedlings and run them for 14-16 hours daily; seedlings indoors need this because greenhouse light alone may not be strong enough, especially in winter months.

Is it worth buying a greenhouse with automatic watering, or should I water by hand?

Automatic drip or capillary watering saves time and prevents overwatering mistakes, especially in hot climates where soil dries fast. Hand watering works for small batches, but once you're managing hundreds of seedlings, automation pays for itself through better success rates and less daily labour.
