Wicking bed growers

This group is dedicated to those who are interested and growing in wicking beds. Wicking beds in conjunction with aquaponics can enable us to grow just about every crop that cannot be grown in standard aquaponics. Lets discuss deign, operation and whatever aspect of wicking bed growing you can think of.See More

Fish-less Systems

This is a group for people who have any kinds of fish-less systems, but yet are not doing classical hydroponics. Where we can share what we have come to find about making-home made nutrients, oganic-hydro, pee-ponics, worm tea hydro, bio-ponics, home-made buffers, water chemistry or anything else that is perhaps inappropriate for fish. As well as experimenting and sharing results for  things that might be alright for our aquatic critters.See More

The Good, The Bad, And The Ugly

This is a place to both share good experiences we have with aquaponics vendors, and the bad and downright ugly experiences we have had.

I have worked as a certified wastewater treatment operator and manager for more than 20 years. My experience includes domestic and industrial wastewater treatment, as well as groundwater remediation. My interest in Aquaponics follows a natural progression of water quality interests. I views Aquaponics as a wastewater treatment system with the added benefit of producing food. My microsystem is a great tool for learning about aquaponics.

Welcome Terri,


Thanks for joining the Aquaponic Gardening community!  I hope you find it a fun place to explore aquaponics.  There is a real blend of experienced and new aquapons in this community, so please don’t hesitate to get in there and start asking questions.  Everyone is quite happy to help out new members – no question is too basic.  
A great place to start is to read the “How to Use This Site” link on the upper right corner, “Start Here” section of the Main page.  You might also find the “Aquaponic Gardening Rules of Thumb” guidelines helpful. Also, consider joining the Colorado Aquapons group (see Groups tab above).


Please participate and check in with us every day!  We are constantly posting news about aquaponics and the good food movement.


Thanks again for joining us, and I look forward to getting to know you.


Sylvia
