6-month PDX Metro AP Meetup Anniversary!

Hello everyone!

Next Friday marks a very special date- the 6-month anniversary of the PDX Metro Aquaponics Meetup group!

Let's meet (for just over an hour) at Dennis' 7 Dees as usual with social time afterward. 

I am open to topics for the meeting- does anyone have any information they would like to present? If there is a topic you'd like to hear more about, we could focus on it. If nobody feels inclined to present, I could start a conversation about a certain topic for the evening.

Some ideas for topics include:

Plumbing/ bell siphon construction

Grow bed media choice

Water chemistry and supplements

Types of AP systems

AP resources on the web


Let's make this meeting a great celebration- a collaborative effort! 

Tell me what you'd like to focus on and the idea that rises to the top will be the one we'll discuss!

After the meeting, let's go to Mi Mero Molé again on 51st and SE Division- everyone had a great time there last time and it is indoors in case of rain!

Add your comments on topic choice below- and see you next Friday!

    Happy semi-anniversary! I was back in MI with family. Sorry I couldn't make it but I look forward to the next one.

    This group is a great resource for learning. I think many of the problems related to the bell siphons are size related. The smaller ones are going to have a harder time breaking the capillary action of water-which is an extremely strong force-to allow air to break the suction in the University of Hawaii design. Sizing up the tubing, not adding another small one is at least part of the answer to this problem. I find all the research done on these to be interesting, however, and will be experimenting with both of the types. I am interested in working with the higher flow rates and creating turbulence in the beds with the larger siphons and I don't expect to have the problems other people enumerated with the UoH design. Time will tell.

      I would definitely like to hear the results of your bell siphon experiments. I do agree- this group is a really good resource for learning.

    I didn't understand why so many people are working with the smaller siphons except that it is easier and cheaper to source the hardware and bulkhead fittings when putting a new hole in the tanks. I would be interested in hearing some of the science behind why the bedding should drain slowly. You can always slow down a big pipe but you can't make a small pipe go faster on a gravity system.

    I will be putting gravel and lava rock in my bed as soon as my KH/GH kit arrives so I can do a baseline measurement of the water for hardness and see if there is a change with just water and no fish for the first week. That will tell me how soluble the bedding material is with little or no acidification in the tank caused by the fish.

    due to the weather conditions and our need to get through the gorge before dark, we have decited to miss the meeting this evening.
    Darn!!!
    Thanks again for giving us these opprotunities to learn and share.

      Ok- we'll see you next time! Take care.

    I would love to see the bell siphon demo! I am fresh back from the 3rd Aquaponic conference in Tucson and will bring a few of my notes if you want to give me a little spot on the agenda. There was over 50 hours of workshops from some of the best, plus keynote speakers at all the meals, so needless to say there was more than could be absorbed, but probably could put together a little overview that would be helpful

      That sounds great Oma! I think our hour at Dennis' 7 Dees will be a little tight with presentations- could we hear your notes on the conference at the restaurant afterward? It would be a good setting for it, since they have big tables we can all sit around. I don't want to miss your summary of the conference- and I am sure nobody else does either!

    I experimented with bell siphons quite a bit this past spring. I can bring some of my failures and my ultimate success to show.

    September 23, 2013

    • Anne P.

      That is great! Please bring those to show- it will be great to talk about.

      September 23, 2013

  • Paul G.

    It looks like I am free to attend this time. I look forward to meeting you folks. I will drive from Hillsboro leaving at 4:00 pm so I may be late.

    September 23, 2013

    • Anne P.

      Excellent! We'll see you when you get there- we meet in a large event tent in the garden space of Dennis' 7 Dees.

      September 23, 2013

  • Anne P.

    Ok- Tom, please consider yourself invited to share your information about short season vegetable varieties!

    Also, Dylan, we could talk briefly about the parts of an aquaponic system as well. I will bring Sylvia Bernstein's book- which I think is a great primer.

    September 23, 2013

  • Anne P.

    Tom- I like it!

    I'm also checking into the possibility of having someone talk about the wiki for the group and/or solar energy for aquaponics.
    If all of the ideas work out - we have topics for three meetings!

    Would you like to prepare a short talk about short season vegetable varieties? I'm thinking 10-15 minute talk with plenty of time for questions.

    September 21, 2013

    • Anne P.

      The wiki is at http://eatfindr.com/g...­

      September 23, 2013

    • Anne P.

      As you can see, I have not found time to start editing it. It needs some input! Please (everyone) feel free to add information to our wiki!

      September 23, 2013

  • Dylan

    Tom, I really like that idea for a topic as it's relevant to now and I have been wondering about that for the past 2-3 months. Anne, I also like the idea of talking about plumbing. I want to bring some newbies so something simple but practical sounds nice.

    I'm excited. :)

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
