• Demand/Market price i.e P6.00 per head.
• Terms of delivery eg. Fast delivery.
• How much to pay for the product i.e price,
reasonable price versus production costs.
• Type of crop preferred by consumer’s i.e guided by
market survey.
• Strategy to make customers prefer the crop i.e lettuce
that is healthy, nutritious and safe for human health.
Organic products of good size, shape, texture, nutrients
composition versus the price.
• What resources available: structural component such
as plant factory to control pests, microclimate and crop
quality improvement strategy i.e irrigation system, bio
fertilizers (vermicompost).
• Consideration of the budget for structural erection
versus economy of business trading viability.
• Collaboration and complimenting other aspects from
others i.e scientific, engineering and mathematics.
• Supply i.e Assurance to continuity of product flow to
the market at required intervals-sustainability

Plant factory
Plant Factories are divided into the following two types:
Fully artificial light-type
Sunlight-typeThese plant factories primarily depend on sunlight to grow
vegetables in greenhouses, while using artificial light as an
auxiliary light source and air-conditioning (ventilation, cooling) technologies in the summer or heating during winter
These plant factories grow
vegetables in a closed environment without the utilization of sunlight. http://www.kingpengintl.com/intelligent-

Nutrient solution supply unit
What you need to build up hydroponics system?
1. A reservoir tank to contain the nutrient solution
2. Nutrient pump
3. Tubes or pipes to distribute water from the nutrient
pump to the growing gutter
4. Growing gutter with channels for plants to grow in
5. Baskets to contain plants and growing media
6. Return system (tubing, channel) to guide the used
nutrient solution back to the reservoir
7. EC and pH meter
NFT (Nutrient Film Technique)
https://www.diynetwork.com/how-to/outdoors/gardening/how-to-assemble-a-homemade-hydroponic-system
Slope is necessary to return the nutrient solution to the reservoir by gravity and to create film.
PROS AND CONS OF THE NFT
PROS:
• Easy to inspect roots• Low water and nutrient consumption
• Environmentally friendly – minimize the risk of contaminating localized groundwater• Plant roots can maintain a uniform pH and EC
CONS:• Flow of nutrient solution stops or pump failure cause
death of crops in a few hours, especially in hot weather• The channels can become blocked by roots of
vigorous-growing plants
DFT (Deep Flow Technique)
PROS AND CONS OF THE DFT
PROS
• Low cost and easy to build up the structure.• Nutrient abundance for plants is present.
• The overflow tube ensures that flooding in the containers is not possible. • Avoid the problems of electricity cut to ensure availability
of nutrient solution
CONS• Instances of unstable pH levels and EC• Overflow may risk to leakage
