Now, if you've made it this far... you're almost done :D

Follow the directions on your nutrient solution bottle. My directions call for 2-3 teaspoon per gallon for RECIRCULATING systems and 1 teaspoon/gallon for bag systems. The reason is nutrient toxicity (more on that later). I will treat this as a bag system with a little more.

When filled to the proper level, my container will be holding about 15 gallons of water. So that requires 15 teaspoons of concentrate. Converting to CCs (the graduation on my syringe), that's about 73cc. I will be adding 80cc of concentrate solution.

So, fill your container with water - begin aerating and then add the proper MEASURED amount of nutrient concentration. At this point, your garden should be where you want it as water is pretty heavy, this goes double for larger systems.

what should the water level be compared to where the roots are?
