Bongojaz Reviewed by Bongojaz on . Hydroponic question ok, I am kinda on a low budget but I need to find the simplest and easiest way to make a hydroponic system. I have an old aquarium and pump if there is a simple way I can make on using those then that would be helpful. If you have step by step instructions or videos please let me know. thanks Rating: 5
