One of the features of the our NFT system is its portability. It breaks down into pieces, is easily carried by one person and could almost be stuffed into a tent bag.
When fully assembled, two people are needed to move it about.....not for its weight but rather because of its size.
The addition of a small nutrient reservoir and a pump and you've got a 48 plant growing system that can be set up and operating in minutes.......and a very good one, too.
If I lived in places where things freeze solid in winter.....or are scorched to a crisp in summer......this would be my growing system of choice. You can bang it together in minutes in the optimum growing season and then pack it away in the basement when it gets nasty outside.
