By The Numbers

One Baltimore City Block is about 2.21 to 2.5 acres of land a 17th of a mile. The acreage is roughly 100000 sqft of land. It requires 10 sqft to install one solar panel. You can install 10,000 Panels will produce 10,000 kw which will produce 17,000,000kwh of energy which roughly adds up to be 2,720,000 dollars a month and becomes 32,640,000 a year we must create the supply because there is a overwhelming demand for energy.

Recycling Bricks: It takes 8147 bricks to a house. Baltimore has 16000 vacant homes which turns out to be 130816000 bricks , we sell the bricks at 96 cent per square foot. Which can generate 125,583,360 dollars.

Growing Food in old no longer used structures: Hydroponics farm systems  in unoccupied City Buildings can produce a wealth of revenue and fresh food for under-nourished communities. 17.5 million square feet in district-owned permanent buildings

• 434,613 square feet in district-owned modular and portable buildings

• 560,000 square feet in buildings not owned by City Schools

Containers are spaced at certain distances to obtain marketable plants and reasonable profits per square foot of production area. There is a tradeoff between container spacing and plant quality: Closer spacing tends to reduce plant quality (yielding more upright, less bushy plants with thinner branches) but results in a greater number of containers per area of production, whereas greater spacing increases plant quality but yields fewer containers per square foot. Optimum spacing would allow the leaves of one container to slightly overlap the leaves of adjacent containers.

Spacing Pots:

Pot spacing is expressed in terms of the distance (in inches) between the centers of adjacent pots. Pots are spaced on a square or diagonal spacing pattern. Square spacing is the most common pattern used for pots, but growers can place more pots in a defined area with diagonal spacing than with square spacing. For example, a grower can fit 400 pots in 100 sq.ft. with 6-inch square spacing and 462 pots in 100 sq.ft. with 6-inch diagonal spacing (see Figure 1, right).

Figure 1 provides information on the amount of space occupied by one pot (in square inches) and the number of pots per 100 sq.ft. of production area using square or diagonal spacing. For example, when pots are spaced on 10-inch centers using a square spacing pattern, each pot occupies 100 sq. inches, and there are 144 pots per 100 sq.ft. (or 1.44 pots per sq.ft.). For pots spaced on 14-inch centers using a diagonal spacing pattern, each pot occupies 170 sq. inches, and there are 85 pots per 100 sq.ft. (or 0.85 pots per sq.ft.).

Minimum pot spacing is determined by pot size. Thus, for 8-inch pots, the closest spacing possible is 8 inches, which is the same as pot-to-pot spacing. As a consequence, you can place 8-inch pots on 10-inch centers, but you cannot place 8-inch pots on 6-inch centers. You can pack more small pots into a given area than large pots using pot-to-pot spacing.

Determining Space:

Much of the information in Figure 1, right, can be determined using a calculator. The following examples show how to solve pot-spacing problems. Example 1. Approximately how many pots are there (per square foot) when pots are spaced in a square pattern on 14-inch centers?

14 inch x 14 inch = 196 sq. inches occupied by each pot12 inch x 12 inch = 144 sq. inches, which equals 1 sq.ft.144 sq. inches per sq.ft. = 0.73 pots per sq.ft ÷ 196 sq. inches per pot = .73 pots per sq. ft.0.73 pots per sq.ft. x 100 sq.ft. = 73 pots per 100 sq.ft (same as Figure 1)

Pot spacing calculations are used to determine the number of pots that can be grown in a given area.

Example 2. In a 35×75-ft. greenhouse with 1,838 sq.ft. in benches, a poinsettia crop will be grown with pots spaced on 14-inch centers using a square spacing pattern. Approximately how many pots can be grown in this house?

Pots on 14-inch centers = 0.73 pots per sq.ft. (from Example 1)1,838 sq.ft. x 0.73 pots per sq.ft. = 1,341 pots

If the bench area could be increased to 2,263 sq.ft., then the number of pots would increase. It’s simple By The Numbers!
