Hydroponic farming methods

Dear All,

am new entrant to your group.
by profession, am Telecom engineer with good experience and now turning to Hydroponic farming.
attended workshops on Hydroponic farming. still to understand more on plant life, how it should be grown, how plants should be taken care, how pest control can be done without using chemical pest controls.

Can we start discussion on this please?
Especially start discussing on seed germination methods (lettuces), transplanting them to cocopeat media, giving nutrients through drip irrigation. then pest control.
