Check out the link for the step by step to build aquaponic box with Ikea Samla.
Thanks to Roger who planted some new veggies in the aquaponic and got the LED grow light setup.
We just tested the water and it’s perfect. 7.0 in PH, no ammonia and nitrite and full of nitrate. Looking forward to seeing these grow!

I have been having red spider mites problems with my balcony hydroponic garden. These bugs are tough and hard to kill. I have tried a few organic pesticides but none of them work. They are eating up the cucumber and sunflower leaves.
I was referred to predator mites by a few organic farmers on weibo. They look badass! They are smaller then red spider mites but literally eat them for lunch. Each adult predator mite will eats about 200 to 400 red spider mites.
I ordered a few bags of them and just finishing deploying them in the garden. There are both adults and eggs in the bag. Place the opening close to stem of infested plants and the predator mites will climb out of the bags to track down the spider mites. It’s a long night waiting but I can’t wait to see if any of them come to action by the morning.
Go Killer Bugs!!!

We are going to open the 4th Mini Workshop of Acquaponic and Hydroponic system this Saturday (25th) at XinCheJian from 2pm to 3pm. Open to XinCheJian Members; and the workshop is free to attend.
The pic below is the hydroponic box we built up 10 days ago at XinCheJian Mini Workshop (#3) and now, they are ready for harvest!
Very amazing growth
The planter built a week ago is doing well on my balcony. Here is the before and after photos.
A week ago
To counter the harsh Sun of Shanghai summer, a Sun Shade Cover is added.
Also, 100 earth worms are added to help process the organic matter in the system. Hope they can survive with constant ebb and flow.
Finally, over 300 Chinese green, tomato, cucumbers, eggplants, and sun flowers are transplanted and we should be ready to harvest in about 4 weeks.
The basils and chives transplanted into the system are growing amazingly.
My outdoor aquaponic farm survived well through the typhoon Haikui hitting Shanghai. The few plants in the grow bed did well and starting to show amazing growth.
The basil at the middle are growing beautifully. Basil are not used much in the home cooking. Anyone who like to taste some aquaponic basil, let me know. I will bring some to the space.
The system is still showing some sign of the young aquaponic system, a bit iron deficiency. Chelated iron has been added to improve that as well as a bag of coral skeleton is added as PH buffer.
Finally, the seedlings are ready to be transplanted and time to get the hydroponic planter ready.
The planter is ordered from Taobao. Good size and come with the drainage screen at the bottom.
Fix the aquarium air stone strip to the bottom of the drainage screen. Thanks to Rocket’s suggestion with his background in water processing, the air stone is mounted upside down. This is really clever one. It avoids deposit on top of the stone to make the strips last longer. Cool idea!
A small piece of PVC pipe with holes is used to tell water level and fixed on to the screen with cable tie.
PVC pipe is used to protect the air pipe from be squeezed by the ceramic ball.
All done and ready to fill in the ceramic balls.
Big ones at the bottom with 2 cm deep of small one covering the top. While filling in the nutrient solution, make sure only up to the big ones’ height and keep the small one dry. The small one is mainly used to insulate the lights and heat of the Sun from reaching the solution to prevent algae growth and heating up the solution.
Transplanted some cucumbers, sun flowers, and other seedlings started in the past few weeks.
Some words of advice, soak the ceramic ball in the water a few days before setting up the system so they will sink into the water. At the last picture, the big ball float to the top while I was planting the seedling.
It’s almost a month since I setup the aquaponic system in Gubei. I have learn a lot about this amazing technology and make fair amount of mistakes. But now, the plants are growing and the fishes are swimming. The system now has 5 grown carps and 10 Tilapia fingerlings and the waters are in good cycles with 0 ammonia, 0 nitrite and good amount of nitrate for plants food. This is becoming a stable aquaponic system.
Now, I just have to wait for the batch of seedlings ready to transplant as well as getting a few more fish fingerlings.
We are getting seedlings from the first urban farming workshop. Thanks to Jia Qi for letting us borrowing her lights.
Summary for Wednesday
We’ll have 2 guests this weekend Saola and Damrey will be visiting – both tropical storms, while that’s going on outside, we’ll be building up a storm inside! it’s time to get your hack on!
David and Roger will be running another mini workshop this weekend, this time you’ll build your own simple hydroponics box to take home, with two different systems you’ll need to let David know by Wednesday, 150 – 200 rmb in materials but you’ll have a ready to use system to take home, contact firstname.lastname@example.org for more information.
The awesome Barcamp is coming, sign up at http://www.techyizu.org/events/shanghai-barcamp-fall-2012/ for September – do it now, tell them you’re from xinchejian! XinCheJian will make our presence known, last time XinCheJian ran operation “Occupy Barcamp”, this season we’re taking it a step up; if you want to be a part of the XinCheJian Barcamp movement – then contact email@example.com
if you have something to say, we want to hear, let us know if you wish to present on firstname.lastname@example.org but please read the guidelines
