Solid lotus seeds are generally more expensive than hollow lotus seeds. This is due to several factors, including their rarity, quality, and traditional uses in Chinese medicine and cuisine.

Solid lotus seeds are the seeds of the lotus plant that have not been hollowed out. They are typically larger, have a thicker shell, and are more difficult to process. These seeds are highly valued in Chinese culture for their medicinal properties and are often used in traditional Chinese medicine to treat various ailments. Their rarity and the time-consuming process of harvesting and processing contribute to their higher cost.

Hollow lotus seeds, on the other hand, are the seeds that have been hollowed out and are often used in culinary dishes. They are less expensive because they are more readily available and require less labor to harvest and process. While they are still considered a delicacy, they are not as highly valued as their solid counterparts.

According to a report by the China Lotus Seed Association, the price of solid lotus seeds can range from $10 to $20 per pound, depending on the quality and variety. In contrast, hollow lotus seeds can be purchased for as little as $5 to $8 per pound. This significant price difference is primarily due to the higher demand for solid lotus seeds in traditional medicine and the more labor-intensive process involved in their production.

In conclusion, solid lotus seeds are more expensive than hollow lotus seeds due to their rarity, quality, and traditional uses. The higher price reflects the additional value and effort required to harvest and process these seeds.
