New poster here but not first grow. However will be my first hydroponic grow. I came across this and honestly know nothing about it. If anyone knows and willing to help me out would appreciate it. It came with out a pump and im pretty sure I need one, just don't know which to get. The only brand marks on it says general hydroponic. So a little information on what I found and maybe a direction on where to look next on forum. I'm on a crappy cell phone and no computer which is why it's difficult for me to search the forum.
