I guess everything will be clarified once I post the schematics.Originally Posted by urbanfarmer
Those three grow bed half barrels will be filled with 3/4 inch gravel, so the space between the rocks should leave about 1/3 to be filled with water, which is why the 3:1 growbed to water tank ratio, which is also employed in aquaponics.
The cups will be added near the top. I may stick to cream cheese containers instead of yogurt containers if the yogurt containers reach the bottom. Thanks for the heads up.
The pumps are 400gph magnetic drive- ie. low maintenance. They also operate via. timer, and so, by using the timer settings, I can get the water to circulate to where its needed, without over flooding.
Wattage is a problem though, so if anything, I will use T couplings and one pump to water the growbeds, and with the rainbarrel and potting soil pump, I will have only 3 pumps.
Again, thanks for your points- I really appreciate it.
