need a good diy for building a small hydro setup for 4 plants.

Yeah... lots of 'pest' looking spots on those leaves...

You should really look up "Ask Lucas" on the web and read all several thousands posts in the thread that comes up. HUGE database of info on growing with DWC.

Stay Safe!

OK so I just switched the lights to 12-12. heres how they r looking as of yesterday. ya cant see the 2ed plant as good but she is looking good to.
the first one is the hydro DWC one. the 2ed plant is the reveging ladie. I just hope the DWC one is a female because its been hell getting it big. I know the DWC one doesn't looks as good as it could but Im doing my best. maybe im not feeding this one enough N.
