Common sense here... you will be using sharp objects, dont cut towards your body, be safe, use adult supervision

, blah,blah. by reading any further you understand i am not liable for any damage incurred while using these instruction. just be safe.
so i really dont feel like spending money on a hydro system, mainly because i just got a new place, and a new car. so i decided to make one. here is the outline and idea behind it.
1. get 2 liter bottle. small rubbermaid or "whatever they are called" container. a blade (once again be safe). air pump, air line and air stone. marker.
2. set the 2 litre bottle besinde the rubber maid container, depending on how you want the bottle to sit (level or sticking out about the lid of the container) take the lid off or use the lid. place your razor on the edge of the container and turn the bottle to scar it in a perfectly level line. go back and cut it.

3. next lay the cut out bottle on the lid on the cut side of the bottle. mark the circumference of the bottle, and cut it out.

4 this is the hard and very dangerous part. please e careful. you could also just buy a cup net, they really cheap. cut lots of vertical spaces into the bottle. (easier said than done)


5 then slide your bottle into the opening in the container.

6.cut a hole in the top for the air line.
7. cut a hole to pour in the nutes and check ph etc. make sure you can cover it with something later though.
8. now cover the entire container in any light proof tape. i recommend doing the lid the same way., and also recommend that aluminum foil go on top of the lid to reflect light back to the plant.
thats all for now. just make sure to clean it all VERY good with a bleach solution(once again be careful wear gloves blah blah blah) then wash with peroxide.
