Noob-y question about amounts of air

right i am buying another airpump (the last one sounded like a horse stamping on your ears) and im curious how many LPH do i need ?

im growing two plants in two 25l buckets so i need dual outlets, so for a good yield how many LPH i need ?

hey so if i did the math right in my head they should be like 6 gallon buckets?? heres an air pump that will be more than enough and has worked for me amazingly http://www.horticulturesource.com/product_info.php?products_id=6350 its not to expensive i am also using it with 8 5 gallon buckets with no problems.. so you oculd probably go down to one of thier smaller models

i heard that the general rule is 1watt per gallon when using airpumps

Good information I didnt know that just set up my first system.

the best one ya can afford & a sprare . couple extra air stones wouldn't hurt either,,stinks to go out and see no bubbles.
