The timer may switch equipment on, off, or both, at a preset time or times, after a preset interval, or cyclically. A countdown time switch switches power, usually off, after a preset time. A cyclical timer switches equipment both on and off at preset times over a period, then repeats the cycle; the period is usually 24 hours or 7 days.
Newer versions of AIM include the Content Planning Module (CPM) and Learning Object (LO) Module. The modules incorporate data from the Job Duty Task Analysis (JDTA) process, which aids the revision and creation of training programs. [5] The latest version of the system is AIM 5.0. [6]
Originally launched under the name The Greenhouse Project, [9] the Hydroponic Classroom program was created in 2008 to increase K-8th grade students' interest and proficiency in STEM education while understanding the environmental issues of their time: global climate change, efficient use of water and energy, building greener cities, and growing a secure and healthy food supply.

The greenhouse industry is the second largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment Agriculture has the ability to produce crops all year round, with the possibility of increased yield by adjusting the amount of carbon and nutrients the plants receive.
These timer apps can be set for a specific time [2] and can be used for tracking working or training time, motivating children to do tasks, replacing an hourglass-form egg timer in board games such as Boggle, or for the traditional purpose of tracking time when cooking. Apps may be superior to hour glasses, or to mechanical timers.
DIF is a greenhouse technique involving temperature control for the purpose of controlling plant internode length and thus elongation rates. DIF's effectiveness has led to a reduction in the need and use of chemical plant growth regulators. Although many common greenhouse plants do react strongly to -DIF, there are some plants which show little ...
Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye).
