well i just got some gutters a few weeks ago and this was the first rain i had and i collected 100gallon on 1 side i will be hooking it up better but i wanted to see how much i can get .. all i can say is WOW.. it did not even rain that hard and only off and on while i was at work.. so i am thinking about getting a 500gallon tank for 2 sides.. i will take more pics after i get my parts made ... i know the gutter guy so he is hooking me up .. or we will see.. i am thinking i can do so much with this free water.. i am now really going to have to work on my raised bed garden.. and i will be starting aquaponics system real soon also.. so enjoy ...
