What you're looking at here is a 3.5 gallon bucket, a 10 inch net pot, a single air pump, a pack of rock wool, some air tubing, an air pump and your hydroton. What we have here is everything you need to do a simple, one-piece hydroponic, deep water culture unit. A base deep water culture system starts out easy and simple like this You have a 3.5 gallon bucket, a nice little net pot that holds the hydroton, a piece of rockwool to wick-up the water, and underneath is an airstone to get the water nutrients bubbling up to the plant. Here we have a 70 liter airpump. This will power the airstone that bubbles the water and nutrients up to meet the rock wool and the medium, pulling up water and oxygen for the rooting system. Today we have a 70 liter high-output active aqua airpump. This one can power up to eight buckets. We have it going on three today. The roots grow down into the water, then are fed with nutrients via the airpump. The nutrients uptake through the root system that are being constantly misted at the bottom. When a younger plant is started, you are required to have more water in the reservoir to hit the rockwool and create a wicking activity and bring water and nutrients to the plant. As the plant grows a little bit larger, you get the luxury for the roots growing down into the water and you can have a slightly lower reservoir, but you still want a good ...
