I have done a trial run of just 3 weeks using worm tea exclusively in a flood & flush system. The results are here to be seen as seen above. I am busy designing  2,3 and 6 growing bed systems. Each grow bed is 600 x 400mm's in size. I have used LECA clay balls as the substraite. Each plant has it's own 100 mm basket to contain the majority of the roots preventing plants crowding each other.
