I used to do a one plant two bucket system, but it took up too much space. All together it held about 10 gallons of water maybe 11. So I wanted to find a single bucket that would hold more water and fill my needs. I know the 8 gallon square buckets you’re talking and used it on my last grow trying to move to a one bucket system. It just didn’t hold quite enough water for my like. Since then I have moved up even more, I have a single 13 gallon bucket. This system when full should hold at least 11 gallons in one bucket. Now, is this 13 gallon bucket larger than a 5-gallon bucket? It is but all in all it’s not that much bigger, a little bit wider and a little bit taller.
Already been circulating water around it checking for leaks and I’m leak free, and I will probably be dropping beans on the 25th
Here is the 13 gallon bucket and you can see it’s not like it’s massive compared to a 5 gallon bucket
