Updates from Codman!

  

It's been a while since an update - but our fishes are all grown up! Here are a few quick pics. Stay tuned as we re-engage this summer.

DIY PV WORKSHOP

Green Neighbors and Boston Architectural College have organized a 2-day Productive Collective workshop in Dorchester to construct PV panels for our Off-Grid Greenhouse! Full series of photos from Day-1.

Codman System Update!

The tilapia seem quite happy - the largest is now over 4" and they have started taking our largest feed.

Lisa harvested much of the lettuce for students' salads and plans to use this basil for a pesto tomorrow!

Do you see the two cucumbers forming at the base of the flowers?!

Todays test shows that pH, Ammonia, and Nitrite are all in the right place. The Nitrate is low because the fish weren't fed over the weekend.

Things are looking very productive and harvest is already upon us 1.5 months in!

Tour of Codman Aquaponics System - WK04

GYOStuff Garden Learning Center

Our friends at GYO have created a number of resources for those of us growing plants from seed, using hydroponics, or other means. Check out their resources and classes here: http://www.gyostuff.com/Learning_Center.html

Particularly useful to us has been the visual inspection nutrient deficiency chart, included in this post or via this link: http://www.gyostuff.com/Nutrient_Deficiencies.html#How_to_treat_nutrient_deficiencies

Codman Academy, Month 1

Here's a look at month one of our operational 120 gallon system indoor aquaponics system - a joint collaboration between the Boston Architectural College, The Productive Collective, and Codman Academy.

We are currently growing lettuce, basil, squash, cucumber, peas, peppers, and mint - all with eighteen blue nile tilapia and four goldfish! Very quickly, the Codman system has shown that it will yield the best results of any PC WApU yet - a true testament to the research we've all contributed the past year of work.

One thing we're noticing is that the bigger the system, the more stable it is and the more productive. Having over 20 fish in the tank really increases the nutrients and this thing is flying. Another aspect is access to natural light - something that we really don't have on other sites.

In particular, Codman has proved to be an excellent site - We have made a great connection with biology instructor Ed Yoo and librarian Lisa Graustein - who are equally invested in the project.

Productive Collective is just beginning to grow.
