I recommended using PERLITE (a puffed volcanic ash) to airate either SOIL or SOILESS grow mixtures.

There are various textures of Vermiculite. From fine to course.

My good friend STARTS ALL his seedilings in vermiculite....but he grows Flowers and herbs....NOT fresh wheatgrass.

You can sprout and grow wheatgrass IN YOUR HAND....it will still be FRESH wheatgrass when it reaches the proprer height for cuting and juiceing.

But remember you may buy OATS before they go into the horse.....or after....What you get in your hand are two different things.

It is not only quick and easy...to save time and effort....and sometimes money$$$$! I use a $30,000.oo John Deer tractor to turn and compost my used grow mats.

The way I grow my "commercial wheatgrass(9years) to help people that do not have the time or location to do it themselves....is VERY labor intensive presently.

And if I changed the Food Grade Sea Kelp Meal for say Liquid Kelp....and replaced my Chemical free Candian Peat with Perlite custom Grow mix from Farfard of Canada.(no wetting agent and no start up fertalizer....I could make TWICE the profit on EVERY pound of fresh wheatgrass we sell.>>>>>Not worth it!

Gone fishing....this time Sabastian Inlet!

No WAY!!
