In my earlier post you would have come across a manual entitled "The Growbox System for Vegetables" a producers manual. from the Ministry of agriculture in Trinidad and Tobago. This manual gives full details from locating a site for your grow box to maintaining your plants in the grow box. It is a very good manual. This is the manual I used to set up the grow box at my school. The only problem I encountered however was that the manual indicated that although a grow box can be any size, a 'standard sized grow box ' should be 30 feet long by 5 feet wide. However as you can see from these photos the grow boxes were a bit too wide and the students had difficulty reaching to the middle of the grow box.
The grow boxes will therefore be reconstructed to a width of 4 feet to allow students to have easy access to the middle of the box.
