Hi, i had a few questions about hydro growing... i have clay pellets (need to be washed) bubblers from fish tanks, water jets, etc. i need to setup a very small, very quiet, efficient grow room... i would not like to give my plants tap water because i live in the city and it has fluoride chlorine etc... can i buy jugs of food/water or can i buy tablets and put it in water i will do a soil grow but hydroponics would be so much better...
