EXACTLY, and planting a seed in a 5 gallon bucket is just asking for problems trying to maintain PH and you are going to waste a lot of water trying to water a 5 gal pot for a seedling. I start my seeds in a 9 oz solo cup with organic seed starter. After about 14 days after sprouting, I pot up to a one gallon container. The next logical step is a 3 gallon, unless you plan on taking the plant outdoors. You are of course free to plant how you wish, but it sounds like you could use a growing guide to read.
