So I normally use 5 gallon buckets for DWC and RDWC. But I also usually grow pretty decent size plants, so the root mass takes up the full 5 gallons by the time I flower them. I'm wondering if a smaller plant can get away with smaller buckets, and how small? Lately I have been putting seedlings in 3.5" netpots in groups of 3 in 2 gallon buckets to use less nutrient solution and save space. They get their own bucket after true leaves. So naturally, it's got me wondering if it's possible to do a 2 gallon bucket grow?
