Our grow mats are made of all natural industrial hemp.  They are an ideal grow media for microgreens, wheatgrass and sprouts.  The loose weave fibers allow your plants roots to grow through while also providing them nutrients.

*The hemp grow mats are sold in rolls that are not pre-cut

Our hemp grow mats are 650 gsm providing a durable mat and still allowing you to cut these to size. 

 Each mat is ¼ inch thick.

1020 Tray Cutting Instructions

  1. Cut into 36" x 19.5" Strips
  2. Divide those strips into 4 equal prices each measuring 9" x 19.5"

Note: this is a loose weave so there is stretch involved when unrolling, cutting, etc.  Meaning all numbers above are approximate.

Ask a Question
  • What are the dimensions of an individual roll? Thanks!

    For a roll that yields 20 mats it will be 36"x100" (this is the the smallest roll we offer)

  • What size are the mats? (How many trays will 1 mat do?)

    The smallest roll we sell is the one labeled "20" for $49.95 and this will allow you to cut approximately 20 - 9"x19.5" mats with each single mat fitting into one of our 1020 trays.  So in other words our 20 mat offering with yield 20 1020 trays.

  • What are the dimensions of each roll?

    For a roll that yields about 20 mats it would be 36"x100" and about 5.2 lbs

  • I am wanting to grow microgreens. I am unclear if using a grow mat would you need to have a tray that has drainage holes?

    Either way will work, just personal preference :)

    A 20 mat hemp roll is 36" x 100".

  • what are the dimensions of the whole,uncut hemp mat? Thank you!

    A 20 mat hemp roll is 36" x 100".

  • 20 mats of 36"x19.5" for 49.95?

    Cut into 36" x 19.5" Strips Divide those strips into 4 equal prices each measuring 9" x 19.5" So 20 mats of half that size, or 10 mats of the size per your question.

  • For your product, HEMP GROWING MAT - BULK ROLLS, if I order 20, now many 10x20 grow pads can I cut from them?

    If you select the "20" size you will get approximately 20 pads for your 10x20 tray.
