Answers:    if money is a limiting factor, why go for a hydroponic setup.you can budge for something which will get like results that will not cost you as much money.what you need to is plant your plants surrounded by a soilless medium,and afterwards hand nurture with a suitable nutrient mix,it may be more labour-intensive than a hydroponic setup,but the results will be similar.
