博茨瓦纳采购需求：温室、玻璃温室、水培法、气培水培法、冷却风扇

I'm looking for a greenhouse with the dimensions of approximately 10m in width, 30m in length, and about 4m in height, totaling around 300 square meters. The design should include roll-up sides for optimal ventilation and ease of access. Could you provide the details regarding the available materials, construction options, and any additional features that come with your greenhouses? Also, please include pricing information and lead times for delivery. I'd appreciate any recommendations you may have based on your expertise and experience. Looking forward to your response!
