  6. What is Conductivity  and why should I care?

Submersible pumps used in hydroponic gardens are rated by GPH, which means, how many gallons of water they will pump in an hour. You also have to consider how high you will have to pump the water. If you wanted to sit your garden on a table by a sunny window and the tank underneath the table, then you might need a little larger pump because of the increase in height. Because the 11 Plant Garden is what I consider a small garden you can use a pretty small pump say a 50 GPH up to 120 GPH
You can use a larger GPH pump if you redirect some of the flow back to the tank.
It's better to buy a larger pump because it seems when you catch the hydroponics bud you always want to expand.

Hydroponic nutrient solution is a very hot topic here on hydroponics online. In the beginning of my experimenting with hydroponic nutrient solutions I always used store bought hydroponic ready mix solutions. Then I realized that to grow commercially I had to find a more economical nutrient mix to use. I have been using Miracle-Gro for Tomatoes at 1 teaspoon and 1/4 teaspoon of Epson salt and 1/4 teaspoon of calcium chloride per gallon of water with pretty good results.
Mixing your own solution isn't easy but here is an example of how to mix your own from Howard Rush's Hydroponic Home Food Gardens. If you really want to to grow successfully  then I would go with a real hydroponic nutrient solution. And my favorite is Formula One A & B from

Level of pH in Hydroponics

pH is a scale from 1 to 14 that measures acid to-alkaline balance. 1 is the most acidic, 7 is neutral, and 14 is most alkaline.
The pH range for hydroponic plants should be between 5.4 to 6.6. If your pH drifts from this range then your plants will develop lock out and won't be able to utilize the nutrients in your solution. PH is best rise or lower the Ph levels optimum range can be used to lower ph the salinity the pH in fish tanks raise PH they suggest to add Asprin.
