How big a batch are you making and what size trays are you using?If you want 4-5ozs. per day then a flat everyday will be needed most likely.Are you growing inside or in the great outdoors?I would first focus on growing well then ramp up for production.I have some pictures of my grass and other sprouts in the Image Gallery in the photos section under grassmans sprouts.I do allot more sunflower than grass nowadays do to the fact it grows so much better and is more versitile as far as consumption goes.Good luck and happy growing.Jeff.
