How to Build a Homemade Hydroponics System Cheaply from wikiHow – The How to Manual That You Can Edit Not all hydroponic systems are good choices for a homemade system. Here is a cheap and reliable way with excellent results. It is a homemade ebb and flow. Steps Note that one tote goes on the bottom and will be the nutrient reservoir. Run a couple of airstones from the air pump and keep them in here. Nutrient solution reservoirs should always be oxygenated in this way. The water pump also goes into this container. Note that the upper container will hold several plant containers, usually filled with expanded clay pellets. In the bottom of this container (out of the way of the plants), drill two 3/4 inch holes. In one hole you install the flood and drain fitting (the shorter of the two). In the other hole you install the overflow fitting. Run a short length of tube from your water pump to the flood and drain fitting above it. Plug your water pump into the timer to flood th Read More Here

If you’re going to build a hydroponics system, it’s best to begin with a container to use as a reservoir. For homemade systems, it’s best to use a fish tank or a similar object. Once you find a suitable reservoir, you must paint it black. The black pain will make your reservoir light proof, because if light enters the reservoir it will promote the growth of algae. It is also a good idea to score a line on your reservoir once it is painted( use a knife, and scratch off paint in a straight line from top to bottom), which allows you to monitor the amount of water in your reservoir. Some people may not have to score their reservoir if they use a floater (Styrofoam), which indicates the amount of water in the reservoir by sinking. However, the line will give a view of the nutrient solution level. Styrofoam should be used in your homemade reservoir. Before installing the Styrofoam into your reservoir, you should use a tape measure to measure the reservoir, from inside of the reservoir Read More Here
