I am setting up my first hydro garden, a combination deep water culture/drip system (similar to what Stealth Hydro is marketing.) I am using a 31 gallon Rubbermaid container and 6in net pots with a spacing of 9 inches one way and 13 inches the other (between centers.) My biggest question at the moment is how full should I fill the reservoir? Should the solution come all the way up to the bottom of the baskets, or should there be some air space there? Seems like I read somewhere to leave a few inches, but I'll be damned if I can find anything related to it now that I really need the info.
Also, I'm guessing that I will be looking at somewhere around 20 gallons of nutrient solution in the tub, how important is changing the water weekly if you keep a check on the pH and TDS/EC?
Thanks
