Short answer: A wick runs through the straw. The wick conducts water, which makes sure your plant stays moist!
🤓 Long explanation: As one end of the Plant Straw sits in water, capillary action will strive to balance the moisture level between the two ends of the wick inside.
The tube (the straw) makes sure no water dries out to the air on the way over.
To adjust for specifik needs of different types of plants and sizes of plants, use a longer or shorter length of the wick in the soil.
