It’s been almost a year since I lasted posted on here. Now I’m back with a little video update below. I bought a new air pump because my last one back siphoned due to the fact I didn’t have it elevated higher than my reservoir…oops! The new one has four air outlets, so I’m thinking of setting up a horizontal system on the other side of my window sill.

I’m open to any advice or comments! Here’s the video update link…

Hey Fellow-windowfarmers!

I’d like to share some pictures of the design and progress of our first ever windowfarm where we are growing peas, mini tomatoes and cayenne peppers :) So far, so good! More updates will follow as our plants grow.

As you will see, the basic set-up of the windowfarm includes; an airlift system using a pump, a nice green hose, a t-joint, two valves, a plastic white cereal container as a reservoir (3.5 litres capacity), 3 plastic white plant pots, two chains by which to suspend the pots from the curtain rail, plastic white tubing to allow the water & nutrients to drain down through each pot and some bbq skewers placed horizontally to keep the white tubing stable and to give the plants something to grab onto! Please feel to add your comments, feedbacks and tips!

Very special thanks goes to my boyfriend Dmitry for his engineering, design and building contributions. It is our windowfarm and I couldnt have done it without him :) .

Grafting to hydroponic tree?

3:59 pm in Nutrients, Plants, questions, R&D-I-Y, Seeking Advice by Walt Edwards

Please forgive me if my netiquette is incorrect.  I’m new to this…

The inspiration:  I’ve been going to the same Christmas Tree Farm for 20 years.  It’s a sustainable farm, and we cut the tree ourselves, but we ALWAYS leave the bottom rung of branches on the tree.  Why?  Because then the tree completely regrows itself by next Christmas.  Every year I’m amazed that these tree stumps grow back as much as 10 feet in such a short time.

So I’m wondering what if instead of starting a hydroponic garden from scratch each season, what if we grafted our plants onto the branch of a “permanent” tree root base that provides all the nutrients for the plants without having to grow a new root and leaf system from scratch?  Wouldn’t this have the same effect?  10 times the growth?  Longer growing season?  Bigger yields?  Simpler irrigation?

I’ve heard that local hero, Luther Burbank, grafted 144 plant varieties onto a single apple tree!  So it seems like it should be possible.  But this is not my area of expertise and I don’t have enough time to research it myself this year.  Feedback?  Thoughts?  Suggestions?

Article about benefits of hydroponically grown produce

1:09 am in Uncategorized by BionicMel

This is a very interesting article, with lots of good information.

There is a large list of plants that can be grown hydroponically, and outlines the environmental benefits of hydroponics. Keep in mind, this is from a website that also has an online store, there is a little bit of advertising. Otherwise I found this to be a good read.

I hope this is useful!

http://www.growhubhydroponics.com/pdf/Hydroponic_Produce.pdf

I think this is my favourite part:

With hydroponic technology and a controlled environment, you have the ability to grow premium quality produce using minimal space, water and fertilizer. Amazingly, with artificial light, 6 square feet of space has been proven to nutritionally feed a family of 4 year-round!”

Video: Progress and 2nd Tower

silox – 1st Week Progress and 2nd Vertical Plant Tower w/ New Plants – March 30th, 2010

This is an update after the 1st week of growing in the 1st vertical plant tower and after building/planting in the 2nd vertical tower of our hydroponic window farm.

We have learned a few things just in the 1st week of setting up, planting and running our hydroponic window farm that I would like to share with you.

*  Mentioned it in my last post, but I cannot stress enough, water quality is VERY IMPORTANT.  The first couple of days I used our city tap water to power the 1st vertical plant tower(before my first video/blog until 3/22/2010).  This was also before I purchased a simple PH testing kit.  The electronic ones are nice, but I stuck with the manual method using a small container and drops to gauge the PH for costs reasons, plus I don’t think I’ll have to use it that often due to the reservoir sizes and the water I use now.  I tested the PH of the city tap water I was using and it was over 7 which is not good. Aside from an unbalance PH, the city tap water also contains chlorine, flouride, other chemicals and various minerals.  Even though water can be naturally dechlorinated by letting it sit 24-48hrs in an uncovered bucket, you still have to worry about all of the other nasty stuff and the PH of the water.  Now, I could go through the trouble of filtering my water which I may do in some form or fashion in the future, but I find it easier and cheaper to purchase RO(Reverse Osmosis) water locally from 1 of the 2 sources less than a mile away which I did and I can happily say I’m now using it.  Right out of the gate, the PH was perfect and no impurities whatsoever.  An unbalanced PH can cause the plants to stop uptaking some or all nutrients in order to protect itself(from what I’ve read), same with all of the other chemicals inside the water.  We do have some indoor AC units that collect several gallons of condensation daily in collection containers when they are working hard all day to cool down the apartment, so we will probably look into using that water instead when the time comes to keep them on.  We are also considering purchasing an atmospheric water generator such as an Ecoloblue which also collects water from the atmosphere/humidity in the air, but also filters it afterwards which allows it to be used for drinking/cooking etc(7-8 gallons a day!) and the hydro reservoirs.

* Adequate lighting is also very important to keep the plants photosynthesizing which equals produce!  I think it’s probably safe to say that most window farms will probably not have 100% of the needed light to produce as quickly or as much as most people desire, but I could be wrong here.  That is certainly the situation in our setup and while we try to use the natural sunlight when it’s available for a few hours a day, we’ve supplemented to make up for the lack of desired light.  We added a 4ft 54W florescent bulb complete with reflector to our window farm and attached to the sliding glass door facing the vertical plant towers.  We reshaped the reflector to open up and allow for light to be casted almost 180 degrees towards the side of the plants which I believe really helps the light be as efficient as possible and keeping unwanted light from shining out of our window towards the neighbors.  You can tell the plants really are reaching to grow towards the light, so much that I’m going to need to move the vertical plant tower back just a hair to keep them from touching it, hehe.  I have the light on a timer for 12hr on/12hr off(6:30am to 6:30pm).

* Attaching the wooden dowels that support all of the plant containers on the vertical plant tower to the reservior for extra support sounded like a good idea at first, but presented some logistical maintenance problems later on.  We corrected this by mounting a aluminum L bracket (the kind designed to hold up a simple shelf) to the top of the window area so they wooden dowels can held straight up via a hook driven into the top of the dowel and inserted into a hole on the end of the L bracket.  All of the weight of the plants/dowel is resting on the floor via the bottom of the wooden dowel and the hook/L bracket assembly is to keep it from tipping over.  This allows for us to easily move or rotate the vertical plant tower and remove the reservior for water maintenance(water replacment and cleaning).  This will also allow me to move the vertical plant towers back some from the light as I mentioned above with a simple modification or two.

* We are using the caps that came with the bottles and recreated the holes in them to be smaller directly in the middle of the cap.  The plan does not call for these caps AFAIK.  Why did I use them?  To keep water from splashing out of the containers onto the floor.  Without the caps or using caps with large holes in them allows for water to flow unevenly which results in droplets that are thrown out the container and that adds up quickly over a few days.  I recut the caps to use a smaller hole(5mm) and this seems to work very well.

Recap of plants we have growing, locations and dates planted

Plants on 1st vertical tower(far left) from top to bottom – planted on 20100321:
1. Butterleaf Lettuce
2. Green Beans
3. Strawberries
4. Jalapenos

Plants on 2nd vertical tower(middle or right) from top to bottom – planted on 20100330:
1. Brussel Sprouts
2. Cauliflower
3. Broccoli
4. Eggplant

I thought it would be interesting to do a little math on the cost to run the light and pump.  With my current setup(1x 54W florescent light and 1x Petco 9904 pump), assuming a 30day month and $0.15/KWh power rate, it costs a mere approximate of $3.50 a month to run the light 12hrs a day and the pump non-stop.  Not bad!! :D

Our future plan is to put a 3 vertical plant tower in the same window on the far right.  In order to do so, we will need to purchase another 4ft 54W florescent light w/ reflector(lights can be daisy-chained together out of the box), another air pump and 4 more 1.5L Ozarka water bottles.  We pre-purchased all of the other materials with the expectations of creating at least 3 vertical plant towers total.

Will try to post an update in about a week’s time.  Happy window farming!

Video: Silox’s 1st Tower

5:06 am in Completed Window Farms, Getting Started, Materials and Resources, Plants, Projects in Process by silox

To avoid confusion, this video was taken on Sunday, March 21st, 2010 and was just now uploaded.

silox – Initial Setup and 1st Vertical Plant Tower – March 21st, 2010

The initial setup and after planting in the 1st vertical tower of our hydroponic window farm. Our hydroponic window farm is located in our apartment sliding glass door area somewhere in Texas :) We are very excited to see how our hydroponic window farm turns out and learn from our experiences. We want to use our knowledge we gain from this to setup a much a larger aquaponics setup(aquaculture + hydroponics) down the road when we move into a house.

This configuration is based from the 3-container, air lift instructions found on windowfarms.org.  We tried to get away with 5 containers, but that seemed to be too high for the water to make it(tried 1 and 2 air tubes).  We settled for 4 per tower(1 more than what the plan calls for).  We also tried getting away with just one air pump tube to power this vertical plant tower, but ended up using two like the plans call for.  I think you might be able to get away with using just one if you were to buy separate, better quality one-way air valves instead of using the ones that came with the Petco pump as each one certainly seems to provide different amounts of air resistance (tested by blowing through each one before installation).

What we are using:
- Petco 9904 Air Pump(4 air outlets and kit includes one-way air valves)
- 1 Gallon or more reservior(8L or about 2 gallons in my case)
- Various surgical type tubing, but most importantly reinforced tubing for bringing water from the reservior to the top to prevent kinking in the line
- Wooden dowel to attach 1.5L plastic water bottles to
- Sports ball air needles (1 for each air line coming from Petco air pump)
- 3″ net cups for plants
- Hydroton(or equivalent) expanded clay pellets for growing medium
- 4ft 54W flourescent light bulb w/ ballast and reflector(reshaped to redirect near 180 degrees on one side)
- Timer for light to keep it on 8-12hrs(depends on cycle of plants and natural light availability)
- Water(Qualtify makes ALL THE DIFFERENCE). Get Reverse Osmosis water if at all possible or something equivalent. Make sure PH is right(between 5.5 and 6.5) and it’s pure.
- Botanicare Pure Blend Pro Grow Nutrients(Organic) for all vegitation phases of growth
- Botanicare Pure Blend Pro Bloom(Organic) for fruiting of plants(haven’t used yet and may not be necessary, so we’ll see)

Plants on 1st vertical tower(far left) from top to bottom:
1. Butterleaf Lettuce
2. Green Beans
3. Strawberries
4. Jalapenos

We will try to post an update once a week for now until we at least harvest most of these vegetables to show trials and tribulations to get to that point(we are hopeful we will make it that far, lol)
