i bought some miricle grow, it says to mix 1 spoon with 4 litres of water.but i dont need to mix so much, how much do u think i need to mix with a cup of water? or somthing smaller than 4 litres of water.
even though you're "not supposed to" use miracle grow, i do. i just took a gallon milk jug and put the appropriate mix of water/fert. in it. of course, i didn't use it all at once, so i had some saved for next time i had to fert.
