Awesome Aquaponics Events for Earth Week (1 of 3)

Various folks are rolling out the aquaponic carpet for Earth Week. I'm going to be holding tours every night, as are several dozen other aquaponics folks across the United States.

For tonight, I wanted to mention a workshop my friend, Sahib Punjabi, is putting on down in Florida. If you've seen the book, Sahib is the one who has created a garden paradise in a vacant alley behind a strip mall. He's got everything going on down there, from floating rafts to vertical towers to media beds, including wicking beds and xeriscape-like root-zone watering of plants and trees along the verge of the parking lot.

Tomorrow I'll talk about free tours being held by members of the Aquaponics Association, but for those of you ready to move forward to some serious gardening, Sahib's workshop near Orlando, FL, is a great opportunity.

Sahib is also working with the non-profit Feed Hunger Now to train folks on how to use aquaponics to alleviate hunger, using "dead space," areas that get sun and rain but that are currently empty.

Sahib's Florida vision is very close to that of Eric Maundu, of Kijani Grows. Hundreds of thousands of people have been introduced to Eric's vision of converting urban wastelands into productive gardens and farms, as shown in the video below:

A third place I know of that is working to serve the urban hungry is The Grow Haus in Denver, Colorado. Tonight I'll close leaving you with a short piece where Coby Gould talks about the neighborhood food hub concept behind The Grow Haus. Very Cool!

Aphids and Worms

Video of Worm Cocoons Hatching

Fortunately, I had several plants winter over, including cabbage parsley, beets, sage, strawberries, garlic, chives, and onions.

Unfortunately, my onion, chives, and garlic on one bed became infested with little black aphids. Interestingly enough, the chives and onions in other beds on the other side of the greenhouse (3-4 feet away) were not affected at all.

Chives, garlic, and onions are supposed to protect other plants from aphids. But apparently there's a type of the little bugs that is adapted to love what other aphids despise. Which is entirely unfair, in my opinion.

After trying for a few days to hose the bugs off in place and applying organic sprays, the black bugs were still thick on the plants. So I decided I had to rip the affected plants out of my grow beds and start over. I figured with luck I would be able to salvage to add to a dinner dish, at least.

It turned out that when I had the plants completely out of the grow bed, it was possible to hose them down really well. All the little black things are gone. So while that would have been good enough for me for adding yummy bits to dinner, I thought maybe I'd give the plants another change to continue growing in the beds. I particularly wanted to save the chives, which had formed a large patch, and which we love to add to dishes.

During the ripping out and re-installing the plants, I found a lot of worms. Like, whoa, a lot of worms. And there were a lot of little tiny ones as well. From time to time I'd also come across these little elongated globules. Unsure what they were, I had flicked a couple of them out into my yard.

Then it hit me. They are worm cocoons! I made sure to leave all the other ones I was finding alone.

Looking it up tonight, I see that worms tend to massively increase population when the weather warms up. So you'll get a lot of cocoons and baby worms either in the spring or in the fall if you bring your worm bins inside. Worms continue reproducing throughout the warm season, of course, but since I don't usually go looking for them, I'd never seen enough cocoons in real life to realize what I was looking at.

Trying to find out more about composting worm cocoons, I stumbled across the video above that shows itty worms hatching out of their cocoon. Apparently you can have anywhere from one to six little worms per cocoon. Pretty cool!

Complete Idiot's Guide to Aquaponic Gardening - it lives!

Today "my book," the Complete Idiot's Guide to Aquaponic Gardening, was officially launched. Around 4 pm today I finally got a hard copy to look at.

A year ago I got a random e-mail, which read:

"I am a literary agent scouting on behalf of a major publisher for an expert to write an introductory book on aquaponics. I found your site and wonder if you have interest?"

I responded, saying something to the effect of "Heck yes!" and began a whirlwind journey creating the book I wish I could have bought, back when I started into aquaponics in the spring of 2010.

The Complete Idiot's Guide to Aquaponic Gardening (CIG to AG as I came to know it) was a labor of love. I did get paid, but this was a work for hire deal, which means I don't get royalties on book sales. Given the way my head works, that's actually really great for my sanity. The book pulls heavily from the collective wisdom currently available via online forums, innumerable scholarly articles, conferences, and endless youtube videos. So I would have felt guilty getting royalties for this book. However, I did put many, many hours into crafting the book, and that labor deserved some payment.

It's been interesting today, reading the book. I haven't seen it for four months, so it's kind of fresh. I find several instances where I wish I could edit the English just one more time to make it read more smoothly. And the glossary includes one problematic typo - nitrite misspelled as nitrate in the definition of cycling (p. 306), but the definition in the body of the text on page 126 is correct.

It will be interesting to see what folks say. I read this book knowing the hours I spent gaining the knowledge contained in each paragraph, not to mention the additional hours it took to distill that knowledge into comprehensible prose. Only I and a few others know how many authorial "darlings" were killed during the creation of this book. If you were one who read an early draft, I think you'll agree the final product is far superior to what you saw.

I hope the book helps people make the transition from hearing about aquaponics to confidently embracing aquaponics as part of their lifestyle. In the mean time, I'm thrilled to have the book itself, with an index! What I would have given for such an index three years ago! It's fascinating knowing how much of that information was unknown to me in March 2010 when I first tumbled across the word "aquaponics."

Lastly, I have to acknowledge again the amazing generosity of this community, and how willing people were to share their experiences and photos. I am humbled to know such wonderful, innovative people!

Now back to enjoying my own garden, and actually getting to tend it, unlike the neglect that writing the book necessitated last year. Beets, bok choy, spinach, radishes, and turnips are thriving, as are most of the plants that wintered over. All the fish are alive, and despite the cold, ammonia levels are nearly zero (a great thing). It's great to merely have to do the simply daily visit I mention in the book, to check water temperature and level, feed the fish, and notice what plants need nutrients or organic pest control. It's my happy place, where the world is simple, life abounds, and the speed of "information" is the rate at which spinach seedlings put forth their first true leaves.

If you have been thinking about aquaponics but haven't yet set up a system, I invite you to take the plunge. It's well worth it!
