The physical implementation of bottles irrigation system for tomatoes plants are shown below in fig.2 each unit of
bottle is connected to other bottle for proper circulation of nutrient. Substrate of coco peat, vermiculite and perlite are
kept in small cups and keep these cups inside the bottles. The substrate has very good water absorbing capability which
is very useful in hydroponics. The nutrient solution flows continuously inside the bottles. The major objective of this
system is to promote eco-safe vegetable production unit. It produces self sufficient, safe and sustainable vegetable
production
