How to save corn seeds (Kernels)
15.1 years ago corn, harvest, seed saving, seeds 1 Comment
Corn is one of those crops I really don’t have space to grow but still like to try every year. This past year I only had one ear that made it to maturity, in the plants defense we have a very hot summer and I didn’t have the most consistent watering schedule so I am to blame for most of their demise. Given I used the last of my corn seed this year and wanting to make the best out a bad situation, I decided to use this ear for seeds for next year.
I decided to go the natural route and simply let the corn stay on the stalk until I was ready to pull up my corn stalks my wife got tired of looking at our dead corn stalks in the backyard which turned out to be yesterday (October 31st) As you can see from the picture above the corn kernels have dried out pretty well, though still contain a little moisture.
To remove the kernels I started by braking the cob in half and then starting where I split the cob pushing the loose kernels off with my thumb starting from one end to the other. Once I have this first row off it should be pretty easy to attack these kernels at any angle.
Lastly I layered the kernels in a single row in an open ended brown lunch bag to allow air flow to allow the remaining moisture to be removed. I put the bag on top of our cabinets in the kitchen and will add them to a homemade paper seed packet after a few weeks or drying (or when I remember they are up there more like a few months late) then store in the refrigerator until time for planting next year.
Now I have more seeds than I probably will ever need for a few years and hopefully will have better luck (or at least remember to water them better) next year.
Fuji Heavy Industries autonomous farming robot
15.1 years ago garden maintenance, robot Leave a comment
We have seen MIT students making robots to tend on their plants. Now Fuji Heavy Industries has created a robot that can completely take care of your fruits and vegetables in your fields (or greenhouse) for a modest fee of only $100,000. You can pick up your own by the next fiscal year.
It uses lasers with reflective panels to orient itself and is 6.5 feet long, unfortunately there are not too many additional geeky details which probably would be helpful before putting down the $100K for this bad boy.
Given this is the cheap vegetable gardener, I will be sticking with my hands and trowel next fiscal year though can’t wait to see a video if this in action.
Twittering computer grow box
15.1 years ago indoor growbox, twitter 2 Comments
Well this is pretty much clichéd nerdiness but given it only required a couple of lines of C# I couldn’t resist. I have updated my grow box software to “tweet” some sort of semi-humorous and not really witty comment appropriate to its current state and share its current temperature and moisture content every 2.5 hours.
For those who want to do something similar, this is how I did it. I one of the many twitter C# libraries and for no specific reason I chose tweetsharp and after adding a reference to their DLL and just the few lines of code (below) you can be programmatically making updates via twitter.
private void UpdateStatus(string message)
{
IFluentTwitter twitter = FluentTwitter.CreateRequest();
twitter.AuthenticateAs("user_name", "password");
twitter.Statuses().Update(message);
twitter.AsUrl();
string response = twitter.Request();
}
If you want to see it in action go to http://twitter.com/computergrowbox.
Right now I only have a handful of not so witty comments, so if you have some good zingers add them to the comments and if I like them I will add them to the list.
UPDATE: Grow box shares its own pictures
I get busy these days and sometimes can’t make it out to keep a close eye on my plants in the grow box. Given I have everything automated the box basically takes care of them, though I thought it would be nice if I could see how they are doing so added photo sharing to the grow box’s twittering software.
I already have the software taking pictures every so often so all I really needed to do what send out the most recent file to twitter. After a little looking I found that tweetsharp already supported this so yet again this was just a few lines of code to implement.
First I needed the logic to determine the last photo I have taken, fortunately I was carefully about my naming using a timestamp based name similar to “Photo_2008_10_01_090130.jpg”, so alphabetical sorting would work just fine. I removed the error handling to keep things brief but here is the code to complete this logic:
string[] files = Directory.GetFiles(photoDirectory, "*.jpg"); Array.Sort<string>(files); string fileToUpload = files[files.Length - 1];
Now you have your photo to upload just signup for one of the photo TwitPic using your twitter account and run the following code using your credentials.
IFluentTwitter twitter = FluentTwitter.CreateRequest(); twitter.AuthenticateAs("user_name", "password"); twitter.Photos().PostPhoto(fileToUpload, SendPhotoServiceProvider.TwitPic); twitter.Statuses().Update("My Picture").AsJson().Request();
Hopefully this, you too can make you own grow box (or other inanimate object) share its feelings on twitter.
Growing blueberries
15.1 years ago blueberry, cheap 9 Comments
If it were up to me every part of my landscaping would be edible. Though my homeowners association may disagree with me but blueberry bushes looks just as nice as any ornamental plant/bush when you visit the nursery with the obvious bonus of free food.
When selecting a blueberry bush, unless you are very patient spend about $10 a plant and get some more established ones (about 1/2 inch stem) You can get the two for $10 plants from your local Home Depot but you won’t be eating blueberries for a couple years. With the larger plants you should pinch off the blossoms to get better growth for the first couple years but I opt to getting my reward now instead of later and enjoy the handful of berries the young plants can produce.
When it comes to plant selection there are a large number of species to choose from with varying fruit size and harvest timing. I would recommend getting varieties that have varying maturity dates so you can enjoy those blueberries for a longer period of time. When I got my first two plants I went with Toro and Berkeley. The Berkeley is a very popular bush given it produces average size berries great for muffins/pancakes/cereal or the occasional snack with a mid-late harvest. The Toro on the other hand produces large (almost grape size) berries which are great for jams and snacks though bit of a mouthful for muffins. If you are curious of other varieties here is a great resource.
I have heard differing opinions on whether you need to have different species to successfully produce fruit after a little research I found this article which explains that blueberries are capable of pollinating with a single species, though studies have shown that having more varieties can produce larger and earlier fruits. So if you have a favorite variety you can go crazy with the single plant though a little diversity seems to always be a good thing.
When it comes to pest control the biggest pest is birds. You can control them by laying some netting on the plants, though in my personal opinion that just gets in the way of me getting my snacks so I opt for the lazy approach and just plant more plants and share with “neighbors”. Worse case I end up with a backyard with some bushes that look much nicer than my current evergreens, and I always can take up bird watching.
One of the most important parts to being successful with your little blueberry plants is soil preparation. The plants need to have an acidic soil and their roots like to remain moist, but not drowning in water. Given my area has an abundance of clay in my backyard, I naturally do not have either of these requirements. To give the plants a head start I dug a 1 foot wide/deep hole and filled it with peat moss and mixed with a few handfuls of compost. Not only will this retain water well, but the peat moss is also naturally acidic and will be a nice haven for a large family of worms in the next few years to add some awesome natural fertilizer (worm castings) Last I purchased I box of organic blueberry fertilizer which provides the primary and trace minerals as well as help keep the acidity of the soil up. I simply followed the directions on the box and watered the plants when there was a couple of days without rain.
Now some of you might be thinking, “hey it is fall why are you talking about growing blueberries” Well this is the “Cheap Vegetable Gardener, right now is a great time to visit your local nursery to pick up some of their “old overgrown” blueberry plants at bargain prices which you can plant now and enjoy some delicious berries next spring/summer.
Pickled jalapeno peppers
15.2 years ago jalapeno, peppers, recipe 10 Comments
My jalapeno peppers did great this year. So good I didn’t really know what to do with all of them. After making some salsa and having several mature red ones as snacks in the garden, I still have about two pounds that I didn’t want to go to waste. After a little thought I decided to make some pickled jalapeno peppers.
CVG Picked jalapeno pepper recipe
Directions: Mix ingredients and bring brine to boil. Either slice or leave the pepper whole. If you choose to do whole peppers, be sure to poke them with a toothpick so they won’t collapse. Fill jars with jalapeno peppers and then fill with hot brine up to 1/2 in from the top of jar. Boil for 10 minutes and feel free to pick some pickled peppers as fast and as many times as you want this summer.
Computer controlled grow box – Part 2
15.2 years ago indoor growbox, water 5 Comments
Though I have made some significant changes to the grow box controller, the actual grow box has undergone some minor but important changes over the past few months.
Automated watering
Now I must say this one is pretty darn simple. Though I will be planning on a slightly more complicated hydroponic setup later I decided to start with a very easy bottom watering technique. Just take a regular old fountain pump (I went with the cheapest I could find) drop it in a 5 gallon bucket of water and attach a hose long enough to reach your planting tray and plug in the power to the pump to your grow box controller and that’s about it.
To prevent evaporation and algae and little bugs making a home in my nice bucket of water, I added a lid with two holes for the water output and power input. The power input required me to make a straight cut with a utility knife to ensure a snug fit while not requiring me to cur the AC line to feed the wire through.
I also cut a hole of the same size as the water output on the bucket lid to the grow box to allow the line to enter while still keeping the box closed.
Exhaust fan control
Air circulation is important for plants to be healthy but when the box gets warmer than expected I installed two controlled CPU fans to help regulate temperate as well as one static fan that constantly pushes air from the top to bottom.
I added a 12 volt exhaust fan to the top of the box (pictured above) to help push hot air out of the grow box with another (pictured below) at the lower part of the grow box to push in cold air as needed. Both of these fans are powered by a 12 volt power wall adapter plugged into the grow box controller.
Heating
Though the computer and lights allow the box to create a comfortable internal temperature, sometimes it needs a little help. For this I installed a regular old seedling heater to hopefully take a little sting out of the cold floor the seed tray is sitting one. Like other components this was simply plugged into the grow box controller.
Putting it all together
My previous version was a little sloppily put together with duct/packing tape (lets just call it prototyping). Though this added some hackiness appear it wasn’t too functional so I added a little strip of wood to support a couple hinges which I created a top which holds the LCD panel.
Upon opening the top you can see the grow box controller and the state of the art 600 MHz PC in all their glory.
As you can see I have still have some cleaning up to do with compress air and maybe a few more zip ties but all in all everything seems to have come together nicely.
