Hey y'all. I'm trying to maximize yield on an indoor soil grow and I was told to use 5-gallon pots rather than 3-gallon. I went to the hydro store and the lady pointed out the "5-gallon" pots. After looking at them I realized they weren't actually capable of holding 5 gallons so I asked her. She said the "5-gallon" term is just a trade name and it doesn't really mean 5 gallons. It looked to me like it held maybe 3 gallons when comparing it to a typical 5-gallon bucket. So, are these what people are using? Or do I need a true 5-gallon bucket type container? I'm doing probably a 3 week veg... just long enough to FIM once and recover then flower. Will these be adequate to maximize yield?
