1. Was at a local plant nursery and found a liquid fertiliser but was told it is not organic. The shop person then showed me an organic liquid fertiliser but its really expensive. I got thinking and was wondering if its possible to dilute vermicast (powder form) to use with hydroponic system. I read that organic fertiliser is more prone to instability than common liquid fertiliser. Please advice.
2. I have some planter boxes. They are rather shallow when compared to those storage boxes. I am wondering what kind of green vegetables are suitable for shallow boxes and what veges have long roots that are suitable for deeper storage boxes. Is there any links to information on length of roots for different types of veges?
