I'm looking to explore options for a half-hectare greenhouse, and I'd appreciate it if you could provide a detailed quote. Specifically, I'd like to know the different types of greenhouses you offer in this size, along with their features and materials. It would be helpful to include pricing, any customization options available, and estimated lead times for delivery. Additionally, if you have any recommendations based on current market trends or popular designs, I'd love to hear your insights. It's important for me to understand the installation process and any maintenance requirements as well. Looking forward to your response, as I'm eager to move forward with this project soon!
