Hello, guys,
I have some extra fermented substrate that I don't need at this moment. I just made too much on the summer-fall last year, and I would like to offer to others who might need it right now.
I would rather make some more new substrate in coming summer than just storing it.
The substrate is fully filled in the USPS Priority Medium Flat Rate Box.
The inner dimension of USPS Priority Medium Flat Rate Box is 11" x 8.5" x 5.5"
That is equal to 514.25 in³ = 2.226 gallon, so it is approximately 2 gallons.
The first box I packed is 9 lbs, but there can be some variations per each boxes.
The price including Priority Medium Flat Rate is ------ (plus PayPal Fee).
*I have more than just one box.
