how much do i pour in??

i just started my first hydro grow. im using a 20 gallon container and two eight inch pots iv just planted and do not need to add fert yet but i need to know how much to add to the water at the beginning of a two week water cycle once the plants grow

I read the instructions on my fertilizer bottle for 'hydroponic' growing, and it worked perfectly ... imagine that :jointsmile:

yeah i made the post before i even looked at the bottle what do you know:rastasmoke:
