I just wanted to add this, in case you wanted to try and save a bit of cash....if you are growing plants that are 4' or less, you don't need to use 5 gallon buckets. 3 gallon pots are about perfect for plants that size, and are actually less than 3 gallons and will save you about 1/2 the soil that you'd need for those 5 gallon buckets. Just my 2 cents.lol
