Why You Don’t Need A Biofilter:

There’s a lot of nonsense about needing “filters and biofilters” in your aquaponics system coming from people who simply don’t understand how and why these systems work. [Read more…]

Water Pumps And Flow Rate In The Vegetable Troughs

The Aquatic Eco Systems/Pentair Aquatics catalog gives a great example of a “cheap” $259 water pump that only uses $813 more of electricity per year than the “expensive” $479 pump. So, be on the lookout [Read more…]

Aeration Requirements In The Fish Tank And Troughs

If you don’t feel like reading this whole post, and just “want the facts”, here they are: If the water exiting your fish tank has a DO of 5 or above, you’re good. If the water exiting your troughs has a DO of 4 or above,

High Density Systems

This is a looong post; we couldn’t figure out any sensible way to divide it into separate posts. It covers High Density aquaponics systems, which are systems that are designed to raise a maximum amount of fish. [Read more…]

A Friendly Testimonial:

Hi Tim, My son, Carl and I attended the training in Texas this year. Just to give you an update. The Sunday after the training, I was coming home from the church I pastor and passed by a co-op that has several greenhouses out front that seemed not to be in use anymore. I drove through to check them out and they were not in use.

A couple of months later,.....we are now the owners of the 7 greenhouses and all that comes with them! We were able to purchase them all for only $2800. My son and I begin deconstructing them on Thursday.

I'm attaching a couple of photos for you to look at them. They have propane heaters, roll up sides, boxes and lights for electricity, fiberglass front and rear walls, and a lot of odds and ends that I believe will come in handy.

I am so glad we listened when you spoke on ways to find greenhouses without spending a fortune. It has been tempting to just "jump in" but I'm glad we waited.

Thank you and many blessings, Rob Rolison

(Below) About $50,000 worth of greenhouses and equipment that Rob Rolison and his son Carl picked up for $2,800 after we explained how to do so in our March 2016 Texas 5-day training. They're going to disassemble them and reassemble at their farm. If they'd bought them new, they be at zero now; another way to look at this is that they have $47,200 to spend on the aquaponics systems to go inside their greenhouses.
