Is non-woven fabric the same as geo fabric for your growbags? If they are, could you provide information about the GSM you use?
The fabric commonly used for growbags is non-woven, meaning it's crafted from recycled fibers that are bonded together through various methods, as opposed to traditional woven fabrics. The fabric typically has a GSM (Grams per Square Meter) measurement of around 650-700.
