We recently had a question about growing wheatgrass in the winter. Very good question! Yes, you can grow wheatgrass during the winter, in fact, that is one of the major benefits! You can grow fresh organic wheatgrass all year round inside your home! Wheatgrass grows very well indoors, a 70-degree climate preferably. It will grow even if it gets as cold as 50 degrees, but it will grow very slow. It usually takes grass about 7-10 days to reach the perfect height for harvesting. Wheatgrass needs indirect sunlight. In other words, if you put it near a window you will have ideal growing light. If you don't have space by a window you can use full spectrum lighting. Thanks for your questions!
