Light on the subject

Oct25 029

I've been pretty busy lately with winterizing outside plant beds and getting firewood so I haven't spent as much time in my new greenhouse as I want. I did want to talk about the lights and barrelponics though a little bit. The above photo shows what type light I settled on. It is a 600 watt High Pressure Sodium lamp with a parabolic reflector. I got two of them and boy, does it ever throw the light out. Here is a close up of the underside.

The reflector is 3 feet across. Should be sufficient. This next photo is taken from the field outside my greenhouse and shows how bright the light is.

Here's another shot. But in this one notice that I have my insulating panels up to show the contrast.

Now back to Barrelponics. The following photo shows a view of the complete system. The bottom tank holds the fish. The top tank is where the water from the fish tank is pumped up to. and the two half barrels, side by side are the grow beds. I have heard that the inventor, Travis Hughey, at http:/www.fastonline.org, is working on a new system that does not need an electric pump and will be bigger. So far this one has been really fun for Hank and I. Thanks Travis!

Here are my fish in the tank (currently they are goldfish, but someday I want Tilapia). Notice the water draining into the fish tank. It is a natural aerator.

This last photo is another look at the fish in the tank.

  1. Thanks for the link on barrelponics (not that I need another project right now...). It is an idea I've been thinking about, and finding a system that works in the real world is a huge step forward.

    We are just on the cusp between design and building on greenhouse #2. It will be much smaller than out first hoop house, have heat, lights, and more active systems. We have a dozen citrus trees that we need to keep alive over our zone 4.5 winter. I've less than a month to put it together. Thanks for the systems inspiration!

  2. Next week I'll be posting my step by step pictures on putting together barrelponics. Travis Hughey will let you download his manual for free. It was easy to put together. Good luck on everything you are doing. Sounds busy.

  3. I do not even know how I finished up right here, but I assumed this put up was great.
    I don't recognise who you might be but certainly you're going to a well-known blogger when you are not already.
    Cheers!

  4. My programmer is trying to persuade me to move to .net from PHP.
    I have always disliked the idea because of the costs. But he's tryiong none the less. I've been
    using WordPress on numerous websites for about a year and am anxious about switching to another platform.
    I have heard excellent things about blogengine.
    net. Is there a way I can import all my wordpress
    content into it? Any kind of help would be really appreciated!

  11. Howdy would you mind stating which blog platform you're using? I'm planning to start my own blog soon
    but I'm having a difficult time deciding between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design and style seems different then most blogs and I'm looking
    for something completely unique. P.S Sorry for being off-topic but I had to ask!

    This astonishing transformation is the result of the lack of boundaries not being set in a relationship
