Codman system ready for prime time!


Seedlings are transferred to rock wool blocks and are receiving initial nutrients from our aquaponics system in Davis Square.
















The Codman system is showing a good base of ammonia (fish waste in green),  decreasing nitrite levels (bacteria 1 in purple), and increasing nitrate levels (plant food in red)

Seedling prep

Took trip to GYO Stuff in Cambridge today to check in on our seedlings - Here's a shot of the basil and lettuce - ready to be transplanted. The Seedlings are growing in a rock wool plug that we will place into the larger 3" 'gro-blocks' and burry those into hydroton pots! There are a few steps to cure the blocks - so I've attached a diagram found on the products website.

Codman System is Cycling - Plants Await

Hi Gateway crew - I have been to Codman a few times this week to make sure our tilapia arrived safely, connect the lamps, and test the plumbing.

The students and faculty are thrilled and can't wait to help out with the project. So many people have asked two basic questions: what is this, and who did this! I think we should make an informative poster for them - perhaps something similar to your presentation to the other Codman Gateway team?

Last time is was there, I snapped a picture of a water test - you can see that our Nitrites have spiked and that Nitrate is forming as well - so both types of bacteria are establishing themselves in the tank.

I called the supplier for our seedlings and we will have upwards of 70 available by Friday.
