as of early 2015 it s approximately $ 3 00 per installed watt the average sized solar panel system is 5000 watts so this brings the total cost to $ 15000 that 15k figure is just an average amount
Hydroponics is a subset of hydroculture and is a method of growing plants using mineral nutrient solutions, in water, without soil.Terrestrial plants may be grown with their roots in the mineral nutrient solution only, or in an inert medium, such as perlite or gravel.ericke originally defined hydroponics as crop growth in mineral nutrient solutions. Hydroponics is a subset of soilless culture. Many types of soilless culture do not use the mineral nutrient solutions required for hydroponics.
Perhaps one of the most common problems in hydroponic systems is the Pythium pathogen and what many growers don't realize is that Pythium being an 'opportunist' fungi, often takes advantage of plants which have been stressed by a combination of high temperatures and oxygen starvation in the root zone.
