just about to start using new hydro kit

have successfully germinated 10/10 'ice' seeds ready to go into my hydro kit.

all I nmeed to worry about is teh nutrients + a ph kit

does anyone know where I can get a decent kit and does anyone use ordinary litmus paper>??????????

I will be using a 400 hps + a 100 hps for veg will a regular timer be ok with these lamps or will I need a contactor??????

I have a kit a bought as a back up to my meter. You fill the vile with water add three drops of solution and check the color. no paper.

I just want ordinary litmus paper but can't find it anywhere man !!!!!!!!!!!!!!

in the uk. I can find loads in u.s. check my new ice seedlings post in indoor growin !!!!

Go to a pet store, they have them for fish water.
