Small Aquaponics Kit with Portable wicking bags.

Continuous-flow Aquaponics  Kit with wicking bags for individual plants.  Plan with Actionable metrix where appropriate .  [Grow Bed ] = [Table] = [Fish Tank] [water] = [fish equipment] = [aquatic plants] = [filters] Grow Bed Size The best suggestion is that the biological surface area is large enough for the fish tank. But a less scientific suggestion is that the grow bed media is twice the volume of the fish tank.    So knowing that water in fish-tank is never the shop-advertised size (in Liters),  The grow bed includes both stones at te bottom for  biological filtration, and dirt bags for growing.  Shape strainers Holes are drilled at the top lip of all tanks (grow bed and fish tank) parallel to each other hole. Then string or fishing rod thread is tied to the top of the tank, to stop the tank from buckling or twisting out of shape. Drainage Apparatus The Bottom of the grow bed is filled with rocks and water, at the top of the rocks lays the drainage pi

Part 1 = Planning and drawing.  This exercise shows how an electronic device uses memory. A piece of memory is like a hole where numbers or letters go. Each "Variable" is a piece of memory.  We have two variables, and we want to put some written information into each variable.  Variable_One = "wassup" Variable_Two = "litigimate" Then , importantly we want to swap the Variables so :  Variable_One = "litigimate" Variable_Two = "wassup" On a piece of paper, draw two squares to represent variables, and try to swap their contents.  You will need a spare variable.   The spare variable holds first variable's contents . then first variable is being filled with the second  variable's contents. Then the spare variable's contents are emptied into the second variable.  So now we understand how it works on paper, we can make an app.  Step One  On the designer screen, you will see the phone's appearance.
