The antonyms for the word "more home-grown" are terms such as "imported," "foreign," or "commercial." These words represent products, goods, or even people who come from or are associated with other countries or regions. While home-grown items are generally considered to be more desirable or authentic, imported or commercial products may offer different advantages, such as price, quality, or availability. However, in the context of some industries, such as agriculture, local businesses, or arts and crafts, the emphasis on home-grown products is often a matter of preserving tradition, promoting sustainability, or supporting small businesses.
