indoor sorry

right now i have a tupperware pan and 2 solo cups with some holes in the bottom of them the pan is fill a liyttle bit with water so they dont dry out

hydro systems can only be sooo inexpensive...your going to have to buy nutrients. I think one of the cheapest ways would be to make your own DWC bucket. Requires a fish tank air pump...minimum of 3 gal buckets and some aquarium glue and lines and last but not least nutrients. Then you still gotta buy a ph meter and ppm meter. Im sure there is a DIY dwc bucket sticky around here somewhere.
