Rooftop garden

Step 1:

4.4 Technology

A hydroponic technology system was set up on the rooftops. The model consists of 3-4 water beds”,

directly attached to on each rooftop. They are made of wooden frames, plastic sheets, foam panels

and cups filled with peat moss and pyralite substrate. The 15-cm deep water is supplied by a water

pipe through an electricity connection from downstairs and maintained by a water pump and water

filter. As an alternative, the project installed boxes filled with soil, having the advantage that no

electricity is needed for water circulation. The biggest challenges for the rooftop farmers were

irregular water supply and electricity cuts, as well as the hot summer temperatures which

negatively impacted the growth of the plants. Economics costs/benefits etc. Measurements should

be conducted in order to assess the actual microclimatic impact. Technical setup: The hydroponic

model is relatively cheap and thus affordable. However, other factors(maintenance, water and

electricity consumption, usage of organic waste and grey water, impact on microclimate

conditions) should be considered for up scaling. Other technical options aside from the hydroponic

system should be explored. Remaining technical bottlenecks have to be tackled by on-site

experimentation. Impact: the microclimate rooftops should be protected from direct solar radiation”,

enhance cooling-off through evaporation and enable a higher effect by spatial clustering and a

bigger implementation area.

Equipment and tools

1. Pickup Truck

Before we bought out indispensable pick up, we bought an old Chevy Blazer. We quickly realized”,

however, that an SUV is not a pickup and cannot substitute for one. A pickup could be the most

versatile and useful long-term investment you can make for your farm. These trucks are essential

for hauling various things, including building supplies, feed, firewood and sod. Teamed with a

trailer, you can move livestock. Although a pickup is a big investment, when you take care of it, it

can last for decades. Good used pickups can often be bought at a reasonable price.

2. Hand Tools

Every farm needs a variety of hand tools such as locking pliers. Companies such as Sears and

Snap-On make hand tools that will last for generations and that come with a lifetime warranty.

First on my list of items to purchase a 25-foot and a 100-foot tape measure; a good claw hammer

with a comfortable grip; electrician’s pliers; a ratchet and socket set; adjustable wrenches in several

sizes; a screwdriver set with regular and Phillips head drivers.

3. Garden Tools

Every small farm needs a flat spade and a pointed spade among garden implements for digging. A

good digging fork is a multipurpose tool, used for breaking up and turning soil in garden”,

harvesting and for manure cleanup around the barn. You might also consider a broad fork. My

preference for hoes is the collinear hoe designed by gardening guru Eliot Coleman. This style hoe

takes the “back-breaking” out of weed control by letting you stand straight up while you work.

4. Fencing Tools

Farms and fences go hand in hand. Plan to purchase a fence-post driver. A driver is a heavy iron

tube that goes over the top of a T-post and has handles on the side. You use it to pound the post

into the ground. Among useful fencing implements is a pair of fence pliers. They are a fairly in

expensive, specialty tool to have. We love electric fences-they are economical, efficient and safe-

but when you have an electric fence, you need a fence tester.

5. Miscellaneous items

We always carry pocketknives when working, and a Leatherman-type tool serves many purposes.

Heavy-duty flashlights are a must when the lights go out during a heavy storm, or when you need

to tend to a livestock emergency in the pasture at 2 a.m. Garden houses are essential; when buying

them, purchase the longest and strongest available. The good ones come with long-term guarantees

card with the receipt stapled to it, because under farm-use conditions that “lifetime” turns out to

be only a few years. The last miscellaneous tool on the list is a digging bar. We use ours for

breaking ice in winter, for digging large rocks out of the garden, construction sites, or fence holes;

and for prying apart incorrigible packages.

Step 4:

Location and Facilities

Rooftop farm is located in Dhaka City and inside of the Dhaka City. The middle city

and the capital of Bangladesh.

Around Dhaka City, there are a large population. It has grown a huge percentage

between 2000to2010. The country is expected to continue to grow by a similar rate

until 2015 when it reaches a large number of population.
