DWC SCrog???

Ok so I have about 7 or 8 DWC plants. I use a few different air pumps w/ airstones in each bucket. I want to do a scrog to keep my plants shorter since their all sativas. Id like to iuse these air pumps if possible to pump nutes from external res. through tubes maybe even to a dripper? Any one have any ideas or setups like it? Dont rlly want to spend more $ ON pumps

PLease help my plants kkeep falling lol

you need more lights. the only reason they would be falling is because of stretching and stretching only happens when the plant or plants are not getting enough light.
