cheap effective plans?

im looking for the easiest, cleanest and most efficiant DWC system and would like to emphasize on cheap. any one have plans that they would like to share on this thread? it would be much appreciated, thanks

there are a lot of inexpensive dwc systems if you want to guild your own, i built mine for about 35 bucks. there are people on here that make them for even cheaper. do some research there are guides all over the place but here is one.

All this is at walmart.
Cheap dark colored tote.
air pump, tubing, and air stones-all in fish area.
Mylar- Emergency blankets in camping section, they call it aluminized polyester. works like a charm!
double sided tape (to stick mylar onto wall or wherever)
Miracle grow (2 types, one for vegg(all purpose) one for flower(bloom booster))
They're so many types of MG you could actually get a lot of different types for more advanced cycles (veg, super veg, transition, flower and bloom)
Digital thermometer and humidity gauge.
liquid PH tester for a pool or aquarium. (had to get a wide range tester from pet store. it reads from 5.0-9.0)
Humidifier
Light bulbs (CFL- 6500k(daylight or bright white)for vegging. 2700k(warm white) for flower.
They have some security HID lights you can convert to work for normal wall sockets, but I like my CFL
The only thing I couldn't find at walmart for a grow op is the net baskets! Had to get big 10" plant baskets at home depot.

That's all I can think of right now, If I remember anything I'll come back
Happy growing!
