A block is about 2 gallon expanded.

Please note, husks may be shipped separately and via ground shipping as due to its size and weight, we don’t want to risk the plants being crushed and this will also prevent shipping from being too high for priority. If you prefer a faster delivery option, please let us know in the note section when you check out or email us at support@unsolicitedplanttalks.com

Thank you and happy planting!
