Using beneficial microbes and or fungi is the way to go! The fastest and best way to see results is to use a tea. If you are using beneficials, you need to be filtering your water. If you are on city water, it is most likely treated with chemicals such as chlorine that kill beneficials. RO filters will prevent this. Be sure to use a sugar product as this is food for beneficial microbes. Enzymes also help in healthy root production (I use Hygrozyme).
