The Tribest Sproutman Wheatgrass Grower SM-350 allows you to grow three trays of wheatgrass in just ten days...right in your own home. If you do a lot of juicing or just have a heavier demand for fresh wheatgrass, you can expand the system up to ten trays. Here"s the refreshing news: you don"t have to worry about lighting, room temperature, or complicated hook-ups when you use the SM-350 Tribest Sproutman grower. Your preferred home temperature will be just fine and no special lighting is required. The trays properly drain away excess moisture so your wheatgrass gets what it needs and no more. You can choose to grow with or without soil and there is a plastic sheet that prevents roots from getting tangled and makes cleaning up much easier once your grass is grown. If you don"t have a lot of space to devote to growing wheatgrass, the Tribest Sproutman Wheatgrass Grower SM350 is a great grower to have around. It measures just 10-inch by 12-inch and can easily be tucked into a corner or slid to the back of the counter without interfering with cooking and other kitchen duties.
