hey man if u dont wanna spend alot of money to grow ur wasting ur time doing a hydro setup u r going to need a chiller to keep res temps within a healthy range also having ph meter is very important...stick with soil grows if u dont want to invest very much money, its forgiving and great for beginners I would suggest this over trying to dwc if u want to upgrade over time u can get into hydro and all the meters and stuff...first go dirt, upgrade ur meters then go hydro.
