Since our goal is to make this eco-friendly we hooked it to my 3W solar panel + powerbank, similar to my "Portable Solar Charger" guide. This guide is great for school projects such as: science fair and investigatory projects
Our Investigatory Project (GRADE 8 - IP):
Originally this project was documented for our "Investigatory Project" last year, about: "The Feasibility Of Growing Crops In A Hydroponic System" Our . I.P. was quite a success, caught some attention and got the highest grade in class.
So the problem goes like this: Today’s rapid growth of human population causes the lack of available space for crop agriculture. The traditional method for planting crops requires labor intensive methods such as: tilling lands, watering crops on a daily basis, using unhealthy pesticides, fumigating the crops. Scientists say that “vertical farming” is the future of plant agriculture, although soil is very hard to transport, especially in tall building. Hydroponics is done to have better control of the nutrients being absorbed by the plants and makes planting on rooftops more convenient and easier
Recommended Seeds/ Plants:
- Tomato Seeds/ Plant
- Mung Beans/ Plant (We used this one)
- Chili Pepper
- Bell Pepper
I'm starting a Weekend Project channel: For the plan to succeed I need to have a number of viewers from YouTube, Facebook & Instructables. Thank you for your cooperation!
Please support my new FB page :D There are more interesting stuff to come!
Step 1: Gathering Your Tools and Materials
- Recycled Container (Free)
- Controlled Fertilizer ($1.00)
- DC Water Pump ($4.00)
- A Cheap Mini Funnel ($0.10)
- Aquarium Tubing ($0.40)
- Water Flow Valve ($0.20)
- T-Shaped Splitter ($0.10)
- Super Glue/ Epoxy ($1.00)
Recommended Pump Kit: DIY Water Pump Motor Water Pipe Power Supply Set ($12.90)
Tools & Equipment:
- Leatherman Multitool (Gift From: Instructables)
- Rotary Tool (Dremel/ Black & Decker)
- Permanent Marker
- Soldering Iron
- Hot Glue Gun
- 12inch Ruler
Step 2: Installing the Water Distribution System in Your Funnel
1st.) Drill a hole on your funnels side for the T-splitter.
2nd.) Measure the inner circumference of your funnel and cut a strip of tube [Formula: (2)(π)(r)]
3rd.) Slit some hole on your tube using a knife, be sure to slit it on 5 even sides. Use a ruler!
4th.) Connect your tube on the T-shapped splitter
5th.) Apply a few drops of super glue to mount your assembled drip system (tube) on your funnel
Step 3: Glue the Assembled Funnel to the Cover
1st.) Trace your funnel on top of your container's cover
2nd.) Use your leatherman's knife to cut a hole cleanly
3rd.) It's now time to warm up your gluegun and mount the funnel to your container's cover. Be sure to seal in the gaps!
Step 4: Installing Your Water Pump
If you plan to hook it up to a solar panel, I recommend reading: DIY Portable USB Solar Charger ($20)
Okay lets get started! What I have here is a non-submersible water pump, which I found from my inventory. I had to drill a hole on the container in order to add a pinch valve (water flow valve). The pump is slightly elevated since it is not water proof.
Step 5: Finalizing the Setup
Use smooth pebbles to hold your plant's roots, make sure they are tucked in firmly.
Step 6: Soil Planting Vs. Hydroponics
Bottom Line: Plants planted on a hydroponic medium, grows faster [Hydroponic Wins!]
