This doesn’t mean blasting them out the air lock of your interstellar craft! There’s a real art to planting seeds and transplants at exactly the right distance to maximize yield and minimize open, wasted ground that will probably grow weeds anyway. The best spacing will give the plants all the room they need to fully develop, and to fill in completely between plants and down the rows, leaving just enough room for you to walk along and pick your harvest. Ideally they’d all be at waist height too so we won’t have to bend over!
