27. Feasibility Question What are the forces of the lights need to be taken into account? Rochester Roots Horticulture Lab27 Best method: Calculations (statics) Given: Mass=11.23 kg Assumptions: Mass of light is equally distributed rigid body supported by 2 brackets brackets are equidistant from center Calculations: ∑Fx =0, ∑Fy =0, ∑Fz =0, ∑M =0 ∑Fx =0 (no forces in X-direction) Fw=(11.23 kg)*(9.8 m/s)=110.05 N ∑Fy=2Fs-Fw=0 Fs=55.025 N ∑M =-MFs + MFs=0

28. Feasibility Question How much power is used by the system and is it acceptable? Rochester Roots Horticulture Lab28 Light Source-3 light sources consisting of 400 Watt HID bulbs use roughly 3 kilowatt-hours of electricity each for a total of 9 kilowatt- hours for the entire system Heating Element-6 heating pads of 11x22 inches use roughly 0.3 kilowatt-hours of electricity each for a total of 1.8 kilowatt-hours for the entire system Sensors-sensors use a negligible amount of electricity and were not included in the calculations Total-the system uses about 10.8 kilowatt-hours of electricity per month

29. Feasibility Question How big is the lab? Rochester Roots Horticulture Lab29 Planting ScheduleJanuaryFebruaryMarch Types of Plants Planted2 -323 Total2 -34 - 55 # of Each Plant??? Total Known Info Table Height = 31.25 in Ceiling Height = 9 ft Table Depth = 33 in Table Length = 322 in Plant Max Growth = 6 - 8 in Plant Trays = 11 x 22 in Max Plants/Tray ~ 72 Assumptions Height of Light (2 ft above plant) = 30 - 32 in Heating Pad ~ 11 x 22 in Light Coverage ~ 4 x 4 ft Each plant experiences each different set of conditions **CONDITIONS CHANGED / TRAY Soil = 2 types Light = 3 settings Temperature = 2 settings Water = 3 levels Using Gaphic Diff colors = light setting 1, 2, 3 Darker vs Lighter = room temp vs heat Label = soil 1, 2 Each tray split into 3rds = water 1, 2, 3 72 plants per tray / 3 = 24 plants per water/tray max plants = 5 types 24/5 = 4-5 of each type per water/tray Conclusion Facilitating all variations of all conditions, using 4-5 of each type of plant, the lab would have dimensions of 132 x 22 in, would use 12 plant trays, 3 lights, and 6 heating pads.

40. Project Statement & Deliverables Problem Statement The experimental horticulture lab is a design project with the purpose of creating a small indoor seed starting lab for the use of elementary students. The lab will be built into the students curriculum, teach the students the scientific method, mimic systems used in real scientific studies, and produce statistically significant results. The students will have access to their plants and be able to control growth parameters such as water, soil, temperature, and light.
