Feeding 16 was never so easy!

SEE HERE I've always liked the idea of geodesic domes as greenhouses. This is an interesting aquaponics system that uses a geodesic dome.

April Musings ... Rockwool Cubes and All That

Well here we are on Easter Sunday, April 8th, 2012.  Around April 3rd I finally got off my duff and planted some seeds in rockwool cubes.  First I soaked the rockwool cubes in water for a day pouring off one charge of water and adding another.  This is good practice to make sure the pH of the rockwool cubes isn't too high.

Then I seeded them with three kinds of seeds: Abe Lincolns, Better Boy hybrids, and Best Boy hybrids, eight each for a total of 24 rockwool cubes in a matrix 4x6.  Here's what they look like now. (see below)

They are currently in a plastic container which I cover and sit near a Southern exposure window since I'm too lazy to keep track of what nights it is going to be cold.  I made up a gallon of weak nutrient, about one-sixth standard growing strength (a teaspoon of concentrate of the blue and the white instead of an ounce) and here's a picture of the nutrient and the container when it is closed.

Then I was walking around my hydroponics design stores (Home Depot and Lowes) and was looking for a "greenhouse".  Of course nothing is as it seems.  A "greenhouse" is something that can be used as a baby greenhouse.  There are lots of clear plastic containers that seem to fit the bill and then I saw a cute thing, an inexpensive radio thermometer which will radio in your outside temperature to display inside.  Wow, I thought.  That's a neat way to create a baby greenhouse and monitor.  So here's a picture of the sensor.  (I already have one on my screen porch so I thought if I put the baby greenhouse out there and the extra temperature monitor then I'll be able to see the difference between the temperature in the screenroom and the temperature in the baby green house on the screen porch.  So here's picture of the sensor (about $25)

And this is the baby greenhouse.  Right now the sensor it out on the screen porch inside the baby greenhouse while the plants are in the house still.  I'll wait until they get a little bigger before putting them out. Here's the greenhouse.  It's just one of those clear plastic containers which you can put outside upside down.  We'll soon see how this works.

Since my camera has a macro capability here is a close up of the two tomato plants best expressing their baby leaves.  So far things are going well.  I'll keep you abreast of the adventure of the baby green house.

Thinking ... It's Winter!

Winter is the time between systems.  This past year without a hydroponics system reminded me in spades why I went over to hydroponics in the first place.  No weeds, fewer bugs, I've yet to have a slug climb up to the plants in the NFT systems.  The result is much better and uniform fruit and higher yields.  What's not to like about that?  But you do get more tomatoes than you can comfortably eat yourself.  The secret (well not so secret) is that beautiful tomatoes are a cinch to give away.  The only problem is people keep coming back for more and are disappointed when they're all gone.  This year Jessica (the better half, often referred to as "The Boss" or "She who must be obeyed") has informed me that I'm to build at least a one tube system because that produces as many tomatoes as she wants and make sure that you plant big ones, not those French Dona's you're so fond of.  Nothing opinionated about that right?  Well a one tube system or even a half tube system is a cinch.  I'll make a little figure to show what the minimum one tube system looks like.  There it is at the top of the post.  Simple really.

The Season's End

Sooner or later you end the season and we've had a couple of overnight cold snaps and the garden in the ground, only the second I've done is quite a few years, is now history. Putting down newspaper and straw kept the weeds down but the garden was plagued by bugs and grubs and things that generally make tomatoes unappetizing although I'm a master at cutting out the bad parts. I've been too lazy to do the final update and roll up the statistics so maybe I'll do that later.

Right now, this year's experience has made me appreciate hydroponics all the more.  I never had grubs and bugs in a hydroponics system like I did in the ground.  I suppose I could have sprayed or something.  Not sure what would have worked.  Overall I had more tomatoes than I knew what to do with.  Jessica said that next year I should just do one tube (seven plants) and that would produce more tomatoes than we'd know what to do with and not be a very difficult system to set up and maintain.  That's definitely a thought.  A one tube NFT system would be fun and easy, so maybe that's what I'll do.  I certainly don't need the kind of production I get off a six tube system and the six tube system is a bit of a pain to set up.  It's not really hard except for the overheads.  The one problem with a one tube system is that I'll probably have to guy-wire the overhead support system since it will just be a single inverted "U" structure which will have no lateral stability unless it is guyed.

Update on the Statistics

Well, no new pictures to show off, so I thought I'd at least update the statistics. So far we've taken a total of 53 tomatoes, although I'm only showing 51 since the first two are from August 1st and we tiny little runts that I took off mostly because they'd been bitten by something and some ants had somehow gotten up to them and were swarming all over one of them. I know that doesn't sound too appetizing, but I washed them off, cut out the part that was bitten and ate them anyway. There is no point is wasting a perfectly good tomato. I like to slice them up and then drop a drop of horseradish sauce on each slice and a bit of salt and then savor them as I eat them one by one. The only thing better is to put them on a juicy hamburger. The total quantity right now is a little more than 18 pounds with an average a bit higher than 5 and a half ounces each. The biggest single tomato and these are all Big Boys has been one 10 ounce one and then three in the 8 to 9 ounce range. As you can see the mode is in the 7 to 8 ounce range.

Status Update

Here it is August 15, 2011 — Where has all the Summer gone. School will start in a couple of weeks and I'm only starting to get tomatoes. That will teach me to start the plants earlier in the future. The picture above shows the edge of the garden after a heavy rainfall which knocked down a couple of the tomato cages. That's very annoying but doesn't really seem to bother the tomatoes that much.
We have a counter top full of tomatoes. In all I've picked 25 so far for a total of 7.97 (almost eight) pounds. Some of them have exhibited some splitting, testimony to the heat and the fact that they're not grown hydroponically. I've also had some blossom end rot. But on the whole they look pretty good as I think you can see. They are all big boys but I don't think they've been all that big. The average weight has only been about 5 1/8 ounces, maybe six if we throw out some of the outliers. I'll put a histogram up of their weight when I have some more data.And here are a few still on the vine waiting to be picked. The first two, rather disappointing ones were picked on August 1st and then it's been fast and furious staring on August 10th, 12th, 14th, and 15th. Pretty soon the counter will be overflowing and we'll be seeking tomato eaters or adjusting our diet to be more in keeping with the largesse available.

Update for Robert

My friend Robert Doumax made the comment to me today in an email: "No news of your weedless garden since June 21: absolutely scandalous!" so this update is for you Robert. Of course all my hydroponics friends can tell that this year the garden is of the "dirt" variety. I've explained but I'm trying to do well by it since it's all I have.

If you compare the picture above with the last picture you'll notice there has been appreciable growth. I've been watering it regularly and giving it some Miracle Grow LiquaFeed see picture below. The results seem promising so far. The tomatoes are all "Big Boys" so they still have a way to go. I put a second picture above to capture the ambiance and show the kind of Miracle Grow I'm talking about. I have to say that this is a promising garden so far.

The things that have worked well are 1) rototilling the garden, 2) putting up the tomato cages (the tomatoes were planted in peat pots and then planted in side a plastic cut to help retain water and deter cut-worms [whatever they are]), 3) laying down newspaper and covering it with straw to deter weeds, 4) watering regularly and using the Miracle Grow LiquaFeed — so far I've used 1 and a quarter bottles. Things look like they are coming along well.

Thanks for getting me off top dead center Robert!
