I have had good results using the Peat Pellets of the brand "Root Naturally"
I place the pellets in a bowl of luke warm water. You can also use a mix of water and mild fertilizer that could aid early growth strength
When the pellets have soaked up the water and fully expanded, they are ready to be placed in the net pots and the seeds can be inserted
The soaked peat pellet is inserted into the net pot. I have opened the top of the pellet covering to be ready for the seeds.
The peat pellet is ready for the seeds to be inserted and the net pot placed into the container for growing.
