Other Instructables that cover elements of the "Hydroponic, Automated, Networking, Climate Controlled Greenhouse Project" are listed below with many more to come:
Part 1: Construction of the Greenhouse
Part 2: The 72 Plant Vertical Garden
The greenhouse when completed should be equipped with a large, centralized hydroponics system capable of supporting up to 40 large plants (tomatoes, bell peppers, banana peppers, etc.) and up to 72 small plants (lettuce, spinach, strawberries, etc.) for a total of up to 112 plants. The greenhouse will be equiped with an arduino based climate control system capeable of monitoring the indoor environment through a variety of sensors (temperature, light intensity, humidity, CO2 concentration, etc.) and automaticly adjusting each variable by controlling different devices (exhaust fans, louvre doors, heaters, grow lights, solenoid valves, pumps, etc.). The readings from all the sensors as well as the on/off status of all of the devices should be sent out over the internet and be viewed remotely and in real time from any computer or mobile phone.
As of this moment the greenhouse's skeleton is all that is completed. I didn't get as much done over the summer as I had hoped because of the nasty weather. However, over the winter I am working on constructing most of the hardware to go inside the greenhouse including the climate control system. I hope to be up and running by the time it's warm enough to start growing.
Each major section of this project should be it's own instructable and when it's all finished I'll compile it into a guide. Right now I'll show you the features of the Vertical Garden ready for installation in the spring.
Step 1: The Supporting Frame
Each horizontal piece holds one PVC grow tube, with a small machine bolt passing through the PVC pipe and the horizontal member and then secured with a nut and washer. Each PVC tube is secured with two fasteners. Each fastener is located near a hole for a mesh pot. That way a screwdriver can be easily inserted into the bolt head while the nut on the other side can be tightened with a wrench.
The vertical members are positioned so that they match up with the studs in the corner of the greenhouse. When the Vertical Garden is installed, it will be attached to the studs via these vertical members.
Finally, at the top and bottom of each outer vertical member is a diagonal cross member that keeps the whole structure from flexing while it is free standing. The bottom cross member is also a point of attachment for the supply manifold.
