There are many growers that use rockwool from cloning right through the flowering. The only time you may have some problems is when you mix it with another media, such as clay pellets (Hydroton). In this case, rockwool holds water for a lot longer than hydroton.

keylime Reviewed by keylime on . Are woolcubes required? I am transfering my plant from mg soil , to DIY hydrobubble system. My question is Do I really need to use woolcubes if my plant has a big stem already and is over 2 months into veg? I seen a youtube video of a guy not using it. But from what I read in the forums people use them, Are they REQUIRED? Rating: 5
