General Gardening Hydroponics start

This article is an excellent introduction to the field (with which I am entirely unfamiliar). It is clear that DaveB is passionate about growing plants using hydroponics; he can cite and explain the technical jargon of the industry with little effort and this helps to induct newbies like myself to the different kinds of hydroponic setups available. A few improvements to the overall formatting of the article and it would be a breeze to navigate and understand! Thank you for this great contribution.
