What must be included on containers of seeds that weigh over half a pound?

The inclusion of the lot number and germination date on containers of seeds that weigh over half a pound is critical for traceability and quality assurance. The lot number uniquely identifies a specific batch of seeds, allowing for tracking back to the conditions under which they were produced, including the source and processing methods. This is essential for both regulatory compliance and consumer safety, as it provides a way to identify and address any issues related to specific batches of seeds.

The germination date indicates the viability of the seeds, informing consumers about how fresh the seeds are and their expected performance in terms of sprouting. If seeds are not planted within a certain timeframe after the germination date, their ability to sprout may diminish, affecting crop yield and overall satisfaction.

The other options, while they may provide useful information, do not fulfill the specific regulatory requirements established under California Seed Law pertaining to labeling and consumer protection for seeds of that weight category.
