$3 LED light bulbs coming soon…
Researchers at Cambridge University have come up with a method to significantly reduce the cost of creating LED light bulbs. LEDs use gallium nitride and requires being grown on sapphire wafers. The new technique allows growth on silicon wafer reducing the cost significantly from $28 to $3 per bulb. The big news for the bulbs is they use 12 times less energy that incandescent bulbs, last for 60 years, and they are far enough in their research that they could come to market in just a two years. Just imagine, in just a couple years you could be buying your last light bulb(s) of your life, unless you physically break them of course.
This this so exciting for indoor growing, my cheap LED grow box works great for the small space for seedlings. When I start thinking of expanding my growing area, the current LED prices make the start-up cost to illuminate a large space is considerable. Because of this I am forced to resort to CFLs as the more economical solution. With these innovations we could definately see indoor gardening much more accessible to a greater audience with this financial barrier lifted. via Gizmodo

Gardening products I would buy if I wasn’t so cheap
16.2 years ago cheap, compost, germination, indoor seed starting, tomato
Today I got my Gardener’s Supply Companycatalog, this particular catalog is dedicated to items to assist you with your gardening habit. You should be able to guess from this site I do my best to resist buying anything for the garden I absolutely need, otherwise I make a cheaper alternative. Well the point of this post is to show what I would like to get if I wasn’t as disciplined.

They sell these Accelerated Propagation System (APS) seed starting kits which have all the basics you expect from a seed starting kits you would find at your local garden store. They include 6 to 40 cells to plant seedlings and a clear plastic dome to help raise the humidity to provide extra moisture for the tender seedlings. The bonus in this setup is it also contains a reservoir which holds enough water to keep them moist for up to a week. With the help of an elevated platform and capillary matting provides just the right amount of water to your plants. At just $19.95 for the 40 and 24 cells sizes this is one purchase I am still considering, since I never have finished my automatic watering system on my computerized grow box and this makes much better use of space than my plastic tub, newspaper pots, and daily watering method I am doing now. |

Eco-Friendly Cowpots basically planting pots made as a byproduct of processing cow poo. The poo is dried, composted and mixed with natural fibers creating a completely biodegradable pot which holds up well during growth and transplanting but biodegrades in the soil after several weeks. I watched an episode of Dirty Jobs which went through the whole process and it was very interesting and environmentally conscience but, unfortunately due to the price tag (about $1 a pot) these are a little over my budget since my newspaper pots are free. |

Gardener’s Revolution Planter – You have probably seen something similar advertised between gardening shows on HGTV (Topsy Turvy) , I know my daughter has and has been talking about growing tomatoes upside down for some time now. She even on her own came up with a ingenious design to do this (not 5 gallon bucket) which I will write-up when we get around to that project. In case you were wondering the improvement this year (or compared to the TV advertisement) it is the addition of a 1 gallon water reservoir which slowly releases water to the plant as neededSelf watering must be a big seller this year since there are also many other variances of self watering pots in many shapes and sizes with designs similar to the original (to my knowledge) the EarthBox. |

Now definitely in the gadget department the Push-Button Kitchen Scrap Composter can take your everyday kitchen scraps and turn them into compost in less than 11 days. The concept on this one is pretty simple:Food + Heat + Spinning = Compost
Of course it crossed my mind of creating something similar myself, but probably would end up burning down the house or if I was lucky just launch partially composted food across the living room at 50 miles per hour. Given the $299 price tag seems like I will be stuck to waiting 3-6 months for my compost to be created. Though it would be much more convenient than walking through the snow to add kitchen scraps to the compost. |

Why should you have a grow box?
16.2 years ago indoor growbox, indoor seed starting, LEDs, seeds
Other than the “Do you really just grow ‘strawberries’ in your grow box?” question. The most common question I have gotten is why exactly do I have a grow box. Hopefully I will be able to answer this question below, as for the first question the answer is yes (without the fingerquotes)
Necessity: I am cheap and don’t want to buy all my plants from local nursery or garden center, but do not have a good location inside my house to grow seedlings with a normal table/shelf light setup. I definitely do not have the space to setup a greenhouse in the backyard. This unfortunately forces me to do my growing in my cold windowless garage. Using a grow box allows me to maintain a safe temperature for my plants no matter what the conditions are outside.
Control: I have nearly complete control of the conditions inside the grow box. I can provide my plants with the perfect temperature, humidity, lights (intensity and wavelength as well as day/night simulation) and even can simulate a slight breeze using a small fan if desired. This gives me many advantages which I would not have even if I could grow indoors. One example of this is growing peppers, which can be fairly difficult in our climate but with some modifications settings in the grow box can create the perfect conditions for it.
Saving Money: Given my options such as the $20 PC Grow Box and my $6 Christmas Light LED Grow Box the cost of entry is pretty low. You do have the expense of lighting the thing but given the 48 watts required for the PC Grow Box and 10 watts of the Christmas Light LED Grow Box even those maintenance costs are reasonable.
Portability: All three of my grow boxes (PC Grow Box, LED Grow Box, Computerized Grow Box) all have a single plug that goes into the outlet and can literally be picked up and moved to another location if needed (try doing that with your greenhouse)
Scalability: Need more space in your grow box? As little as $6 can get you a new one, or $10 worth of lumber can double the size of your existing one (assuming your old lighting can support the space) You are limited to what your creativity can imagine.
Fun: Call me crazy, but I like the idea of tricking my strawberries that it is a nice spring day and get them to start blooming and producing fruit. If all goes well I can move the plants outside during the real spring and get even more harvest while freeing up some space for more plants.

Cheap Vegetable Seeds
16.2 years ago cheap, coupon codes, free, seed saving, seeds
Looking at my web logs I have seen the query for “cheap vegetable seeds” a few times so figured would be good to help people find what they are looking for. Being The Cheap Vegetable Gardener, I can do better than “Cheap vegetable seeds” how about some “free vegetable seeds” as well.
Cheap Vegetable Seeds
- Buy online — You can find a much greater selection and some great prices compared to your local home and garden center. For example right now:
- One of my favorites is Burpee Seeds, they have been around since 1876 and definitely know their stuff. The actually have a seed sale going on now where you get $15 off on order of $75 (just use code AFFB4A35) expires on 1/15
.
- The name is not too exciting but Generic Seeds
offers no thrills packaging with quality seeds and very reasonable prices and if you spend $20 or more shipping is on them.
- One of my favorites is Burpee Seeds, they have been around since 1876 and definitely know their stuff. The actually have a seed sale going on now where you get $15 off on order of $75 (just use code AFFB4A35) expires on 1/15
Free Vegetable Seeds (pretty much)
- Ask your neighbors — Notice your neighbor is a gardener, check if they want to go in on a seed order and share unless you really need 200 carrots this year.
- Harvest your own seeds — If your plants bolt to seed early this year, don’t pull them out let them create some seeds for next season. Notice your neighbor has some seeding plants, ask if you can get some (important part is to ask though)
- Get seeds from the grocery store — Before putting those vegetables in the compost bin, set the seeds aside to let them dry and you got some free seeds. Though a word of warning many vegetables are hybrids and may be infertile or not produce the same quality of product but hey its free.
- Check your spice rack — Many cases you can plant seeds from your spice rack. Some ideas, mustard seed, dill seed, coriander, poppy seed, celery seed. If your spice rack is lacking you can pay a few cents buy a teaspoon of organic spices in bulk, last time I bought dill seeds got about 100 seeds for $0.05.
- Seed swap web sites — Below I have listed a few links where you can share seeds with others. This is a great way to find some heirloom seeds you might not be able to find in stores/seed catalogs. In many cases people will offer seeds for free by just sending a SASE (Self Addressed Stamped Envelope) Just remember to pay it forward when you come into a plethora of seeds yourself.

Using WonderSoil for seed starting
16.2 years ago cucumbers, fertilizer, indoor seed starting, vermicomposting, wondersoil
I had great results using coconut coir last growing season it was great to work with, retained water great for young seedlings, and was economically priced. The only challenge was actually finding some to use this year. No luck in local stores, last year I only could find a single block in one hardware store. Online there are plenty of locations that sell them, but unless you have a need for a couple metric tons, the cost of shipping can be more than the the product itself.
Finally, I found a solution to my problem WonderSoil
- Shake, Water, and Plant — 1/2 inch mini wafers that can be added to any of your pots. In my case I underestimated the expansion of these little things and made a little mess and it overflowed on my table (apparently 3 was the magic number not 4)
- The Tube — There are larger wafers made specifically for 4 inch pots, in my case this would be newspaper pots
- Reground Wafers — This is basically a loose version available in 2 or 5 lb bags. This is a more economical option which I will plan on using when doing larger seed trays.
For Christmas I got indoor seed starting kit which came with pots/seeds/peat pellets. I decided this would be a great opportunity to do a little side by side comparison. From the start I was WonderSoil seemed like the obvious winner. After adding a little water, it fully expanded in just a few seconds and was fluffy and ready for me to drop a seed in, the peat was a swampy mess.
Peat pellets Left, WonderSoil Right
After a few minutes and fluffing with a fork the peat was ready to planting. I put cucumber seeds in both peat and WonderSoil pots and I will provide some updates on how things progress on my little experiment.
After the WonderSoil had some time to settle in my cheap LED grow box I did see some strange formations appear in the soil.
I little concerned I went back to their product and I believe this is their “water saving polymers” in action which I would assume is some sort of gel crystal which is supposed to save up to 50% water. They also boast about use of worm castings which I am definitely a fan of as well as addition of a balance of various micronutrients.
I will have to wait and see if the product produces as well as it claims, but I must say I am definitely impressed at this point and have high hopes for WonderSoil for this years seedlings.

Computer controlled grow box – Part 1
16.3 years ago cheap, computer, electronics, indoor growbox, PC thermometer
The Idea and Design
My PC Grow box was very effective though it did have some shortcomings along with my desire for tinkering caused me to create a new version code named “Project Everbearing” after the test subjects for the project, several Everbearing strawberry plants I propagated from my garden last Summer/Fall. The specific shortcomings I wanted to overcome were temperature control and limited size. My grow box has to live in my garage so on cold nights the temperatures can fall low enough to kill my summer seedlings (tomatoes/cucumbers) Size is an easy fix just make it bigger though it is more difficult to keep a larger grow box warm and still well lit.�
My solution to both of these problems was the addition of a computer to the system. First computers generate heat, using this along with computer controlled fans and incandescent lights (heater) allow me to regulate the heat to my desired levels. This is the point a normal person may have just stopped, but I am far from normal and decided a few more features, which I will explain more below.
The Structure and Insulation
First comes the structure, upon inheriting a set of shelves from my sister, we ran out of room for some of our existing storage shelves (see above), though we used the buckets to store loose toys on our new shelves we had the structure of the old one sitting in the garage for some time. After many passes by in the garage not knowing what do do with this shell, it finally came to me that this would be perfect for my new grow box, (Reduce/Reuse/Recycle) in action. The only customization required was the removal of a couple of the wooden dowels and I was ready to add some hardware. Of course you could do the same thing with an old bookshelf, cabinet or just with construct your own frame with a 12”X1”X8’ foot board cut in two along with two 1”X1”X8’ pieces of lumber cut into two. Screw one 1”X1” in each corner and should should have a pretty solid frame. For the top I used pegboard mainly because I bought a 4’ by 8’ sheet when I only needed half of it but worked really good to use zip-ties to secure various components and provides decent airflow between the computer and growing areas.
Second comes insulation, after some not so careful calculations and measurements I determined I could cover the 3 exposed areas with 2 sheets of 2’ by 4’ sheets of insulating Styrofoam. I glued and taped (duct tape of course) the Styrofoam which was cut using a utility knife and straightedge to cut to size making sure I made the top straight and flush. I then created an exactly copy of the other side and one more piece for the top. Using a long strip of duct tape I created a hinge for the top and glued side of the box. The last piece I simply fit into place using a tool box to ensure a tight fit but also allows easy access to plants when needed.
The Lighting
I went cheap on the lighting taking from the success of the PC grow box I decided to go with a similar setup using $2.00 home depot wired sockets hooked up to an couple old computer power cords. I went with two 24 watt CFL bulbs and one incandescent bulb. Though the incandescent is not as efficient and the CLFs it does provide a full spectrum of light and a little extra heat which the box can use in the many times cold garage where it lives. The CFLs and incandescent exist on two separate circuits so they can be controlled independently by the software.
The Software — Grow box brains
Now I know all of this could be done with a Basic Stamp or Arduino pretty easy, but I wanted the ability to track history and have a decent user interface to look at, so I wrote a windows form application using C#. To cover the basic functionality of temperature control I used the parallel port outputs hooked up to the computer’s parallel port to give the software the ability to turn the lights on and off. By configuring a “sunset” and “sunrise” time which I am in complete control over the lights will turn on and off as appropriate. I added some logic to ensure the plants stay at a comfortable temperature (thresholds configurable) by turning on the incandescent bulb when it is too cold and an exhaust fan when it gets too hot. In order to allow the computer to know these temperatures I used a PS2 controller to create two temperature sensors one for the area the plants are growing and another for the top area where the CPU resides (computer was too old to have onboard temperature sensor)
My daughter thought it would be cool if we have some sort of automatic watering system. I agreed, so I added a moisture sensor and created an algorithm to periodically check the moisture level and activate a water pump to add water until it reaches the specified moisture level. I still need to buy and hookup the pump but coding portion is complete and tested.
I live in the Pacific Northwest it rains a lot and can get cold in the evenings and I don’t want to trek out to check on my plants. solved this by adding the computer to my Wi-Fi network now I can take look at them by connecting to the machine wirelessly and see how they are doing through it’s webcam. I also take periodic pictures of the plants so I can create cool time-lapse videos of progress like the one below. I also have the ability to browse through pictures taken at specific time periods.
Finally to store all of this data I installed SQL Server 2005 Express (free) which allows me to track historical data of the conditions and images over time. If you have data, you definitely need some graphs. Being too lazy to do this graphic work I leveraged ZedGraph (free) to allow some visual tracking of temperatures and moisture content.
Features for future versions (Beta 2?)
- Finish automated watering
- Add automated red LED lights for flowering stage
- Install LCD Panel
- Make box look better (real door which does not require tape to open/close)
- Create single USB controller for lights/sensors
- Better/additional camera
Video of grow box “booting” up, personally I like the flashing lights when the computer sends signal through the parrallel port. If you are old enough to ever have a printer that used a parallel port this is when it would make its annoying sound letting you know it was alive.
