培植土平面的一面是用來種幼芽類，像小麥草、蘿蔔苗、苜蓿芽等以量為主的植物。種之前先把種子浸在清水中約 1-2 小時，再平均舖在培植土上便完成。種植香草、沙律菜及其他需要較多及整齊生長的植物，要用培植土有小洞的一面。把 2-3 粒種子放入洞內（用水輕輕沖洗洞水有助種子落入洞內底層吸收水份）便可直接發芽生長。Flat surface is for planting young buds, like wheat grass, radish seedlings, alfalfa sprouts, etc. Soak seeds in water for 1-2 hours, then spread out evenly on the flat side of the growing medium.
Use the side with holes while growing herbs, leafy salads, and other plants. Put 2-3 seeds into each hole (gently wash them down with a stream of water), then germinate and grow directly.
