Prices for same dimensions of a mat can vary, why?
Because of GSM, (Gramm per square meter). See a detailed article at the end of this post. There are in general three standard GSM on the market:
- 1300 GSM
- 600 GSM
- 400 GSM
400 GSM is significantly cheaper than 600 GSM or 1300 GSM., obviously with an impact on growth results, which have to be taken into consideration. Its important not to conclude simply on thickness and dimensions, but rather on GSM metric. microgreen-mats.com has managed to produce a very thin mat, which still fulfils growing requirements.
