• Why are there differences in container size versus volume capacity in nursery containers?

  There are several different comparisons of gallons:

  Nursery trade gallons versus standard gallons

  Liquid gallons versus dry gallons capacity

  U.S. gallons versus imperial gallons

  When referring to gallons there are different capacity equations In the United States and other countries. A U.S. liquid gallon is defined as 231 cubic inches, which is about 3.785 liters. In the United Kingdom and Canada, a gallon equation is referred to as an imperial gallon. One Imperial gallon is equivalent to approximately 1.2 U.S. liquid gallons.

  *Note when liquid gallons are used as reference to gallon size, they are the capacity of liquid that can be stored in that size, not the mass of the liquid itself.

  The volume of liquid found in a container of milk for instance is much different than the volume of soil found in a nursery pot.

  To confuse matters more the term 5-gallon nursery pot will vary between nursery pot suppliers depending on if they are manufacturing a standard 5 gallon, a squat 5 gallon, a tall 5 gallon or a tapered 5 gallon. Most horticultural pot companies refer to their sizes as #5 rather than a 5 gallon because of this.

  Differences in Gallons themselves:

  1 liquid U.S. gallon = 3.78541 liters

  1 Imperial liquid gallon = 4.54609 liters

  1 dry gallon = 4.40 liters

  Another variation in what the inside dimensions are of a fabric hand sewn container versus a hard plastic (injection molded pot) is the fabric material is cut. When the fabric is sewn into a pot it will vary up to ½ an inch in the folding of the seams which will cause a variance in the dimensions, therefore creating slight differences in the volume of its contents.

  Bottom line if you ever thought that a 1 gallon you get at a nursery with a perennial plant looks a lot smaller than a 1-gallon jug of milk, you were right! One is holding soil; the other is holding liquid and the two have a different conversion of volume.

  A 1-gallon nursery pot may only really hold 0.664 gallons of soil.

  A standard nursery trade gallon is approximately equal to 0.71 of a U.S. liquid gallon.

  The gallon sizes in nursery containers should be considered approximate sizes. The best way to figure out which size container you will need is to check the dimensions.

• Is FDA approval required at this time for Grow Bags, Nursery Pots, or any Horticultural containers?

  Short answer is no not at this time. Our understanding is that at this time the federal government does not view growing Cannabis as a federally legalized act and has not yet required that they meet FDA standards test 21 CFR 177.1630 (contact with food, drugs, biologics and cosmetics).

  The FDA requirements are of course inevitable since it is important that container manufacturers create safe non-toxic containers for the use of growing plants that will be consumed by humans.

  We at Root Pouch believe it is important to our customers that our containers have been tested and have passed safety test for contact with food. We have decided not to wait until it is required and have taken it upon ourselves to ensure that the containers we produce are free of harmful contaminants that may effect the quality and safety of the plants grown in them.

  All our grow bags have undergone rigorous testing by BACL (Global testing and certification lab) in accordance with FDA contact test 21 CFR 177.1630
