More about Kratky Hydroponics

In my last post, I wrote about Basil in a Kratky Can, and I want to include the video update we did on this experiment with this post.

The Kratky method of hydroponics addresses a few issues some people might have with hydroponics, one being the need for electricity to run the pumps for the systems. Eliminating that factor makes this method attractive for those wishing to reduce their dependence on these types of energy sources. 

But this method does have some limitations, limitations that may or may not be overcome with certain modifications to the system. For example, the basic concept speaks to growing greens and lettuces – quick growing crops that are harvested within a specific timeline. They're ready to harvest by the time the supply of nutrients is spent.

But for plants such as tomato, cucumber, and squash that have a continuing cycle of production, the Kratky method doesn't seem practical. You would need a container with a 12 inch depth for the roots; you would need to consistently refill that container; and you would need a way to stake the plants.

Well, that just sounds like a challenge to me.

You'll note in the video that I consistently refill my Kratky cans with fish water, and the basil, then, just keeps growing, and I continue to harvest basil leaves. That's a start to addressing one issue, anyway.

So, I'm working on a way to apply the Kratky method to fruit bearing plants. I can work on this over the summer, while my soil garden takes its respite.

In the meantime…

From the top of the ladder

Temperatures are climbing here in Phoenix, and we're reaching the 100 degree mark in the afternoons. Tomato production in the soil garden is slowing down, but the eggplant is going strong, as are the sweet peppers and hot peppers. Not sure what's going to happen with the squash and cucumber though.

The sun shades are up, and though we didn't get to video the installation, I did manage to snap a few photos. From the roof, no less.

And I purchased a blueberry bush. It's self pollinating, so I don't think I need to get another one for cross pollination, but I just may pick one up anyway. Because I want to. I'll be getting those into the garden next week, and very likely will have a few words to say about it. I'll take some pictures.
