Description
Stonewool Macroplugs are a sure bet for optimum germination. They start as basalt rock and chalk that may be melted, spun into cotton candy-like fibers, and in any case compressed into plugs. Their fibrous structure creates a super air-to-water ratio which contributes to robust root development all the way through all of the plug. In case you are able to experience phenomenal growth with premium rockwool – the Grodan Macro Plugs are your gateway to better growing.
