No clogging at all yet- the worms seem quite happy and always see lots of babies when I dig into the bed. I'm using black cinder for media. Never found ant wasabi plants- the one source on the mainland that said they would have some available in the spring, never produced. I haven't really looked since then.

Hi Chris- Just wanted to say congratulations on that big tilapia in your new profile pic, and on expanding your operation with a new website and all! Well done!

Hi Chris, i am reallt impressed with your set up, it looks very good.

I have one question for you, what is the material you use for the grow beds, for support and water containment.

Hi Chris, thanks for the quick response.

OK, that's what I was picturing....that you were cutting the ply at different heights/angles to match the ground level.

I have to agree, deeper water is more temp stable. Here in central FL, we are (semi)tropical, but this past winter we had a few weeks of freezing temps.

Thank you for the information Chris....have a great day.

Hi Chris, Thank you very much for the pointers.
Now that I looked closer at the pictures....I can see the 2x4's at the top and the ply behind.
2 questions if I may....how deep/tall are they ? The ply looks to be between 8 to 12 inches (?)
Also, what is "Sickens" ? Is that a brand name of water proofing for wood ?
Again, thanks so much for the info.

Hi Chris. I was checking out your pictures.....very nice set up ! What really caught my eye was the picture where you were setting up new DWC grow beds. The picture shows 2 of 4 beds set up and ready.
Looks like you laid ground cover cloth down and built on top of it. Did you use "PT" 2 X12 's and drive rebar in to hold up the sides ?
This may sound like a silly question.....do you have termites in HI ? The reason I ask, I'd love to copy your design....but here in FL, we have 'lots' of termites. I was considering raised DWC beds, but it would be a lot more work and cost.
Thanks for the great idea(s) Chris. Take care.

Ha! Sure enough, that was me. Small world, Big Island. Interesting idea on growing Wasabi- I googled it and it looks quite fascinating. Worth a shot, for sure- I'll try to get my hands on some.

Aloha Chris! Finally another member from the Big Island! Your system is amazing- and Kona has the perfect climate for aquaponics. Here in Volcano rainforest we tend to be somewhat 'insolation deficient', but I'm trying not to let that stop me. Give me a shout if you ever find yourself headed for Volcano and we can talk story...
