DEAR SPROUTMAN: I have been growing and juicing wheat and barley grass for about six months now and have a couple of questions that I’m hoping you’ll be able to help me with: 1- Once I cut the grass and juice it, can I let it grow again for another round of harvesting? Or does the nutritional content of the grass diminish after it’s grown enough to be harvested once? 2- I see that you have some trays for growing wheatgrass without dirt. I’ve been growing mine in dirt and mineral powder supplements. Will I lose any of the nutritional value if I grow it without dirt? Thanks so much!! – Susan

DEAR SUSAN: The nutritional content of the grass diminishes somewhat. Most people do not juice the second growth, but there is no absolute rule. To answer your second question, no nutrition is lost without dirt. I do a full comparative study on soil vs. no soil in Wheatgrass Nature’s Finest Medicine on  page 57. I recommend using Liquid Kelp to enhance the nutrient value of the grass.
