UGro Plug is dried and compressed substrate so you need to start by hydrating the plug. You need a container with water, with some root stimulator to help the seedling finds the necessary nutrients it needs in the early stages of growth.
Once you have prepared the mixture, introduce the Plugs into the water.
Within seconds you can see the coir begin to hydrate and increase in volume.
Now all that is left is to wait. Within 4 or 5 minutes, the Plug is fully hydrated and ready for use, either to germinate seeds or to clone/cut the plants.
