Help first grow ever anddd i have a good setup but i have a 20 gallon normal storage bin like all the videos on youtube but thats a lot of water to fill and weighs probably 800 pounds soo, i need helppppp
Well yes when the roots get big enough they need to be in the water. leave a few inches below the net pots and the water level though. And I'm assuming you already know to put air stones in the res.
Your supposed to use a water pump to get the water out... they cost like $20-30. Normally your system will have a pump anyway, DWC is about the only exception.
Yea definately use an air pump with an airstone running 24\7. I also recommend using a 5 or 3 and a half gallon bucket( home depot or htgsupply.com). Using that 20 gallon storaage bin is really inconvenient.
