Hey all i started my first hydro a couple of weeks ago, and i took a plant that i had growing in soil and transferred it over to a hydro system that i put together from a youtube tutorial. at the moment i am not home, but plan to put pics up by monday. i have been researching what exactly i need for my hydro but it seems that i got it wrong. i have a 18 gallon tub with four pots in it. i went sorda ghetto on it and used tubaware for the net pots. but i really want to know is what is the right amount of food, and hydrogen peroxide that i should use to get the best results. i fill the tub up t0 16 gallons and have the pots just right on the surface of the water. i am really new to growing and need some help with my hydro to get the best grow out of it. Thanx for advice.
