Supplier lists rot in a particular way: companies rename, merge, and get bought, and the old name keeps circulating for years. We track the renames and point at the current company. For a number of nutrient and lighting brands we hold structured data on their actual product lines, analyses, and specifications from our own chemistry work; those cards carry the Ours badge.

A handful of anchors come up in almost every serious answer: Johnny's Selected Seeds for seed and tools, walk-behind tractor dealers like Earth Tools for BCS equipment, and specialist houses for drip irrigation, trellising, and season extension. This shelf lists them by category, each with what they are actually best at.
No, and they cannot. There is no paid placement, no affiliate link, and no advertising anywhere in the Library. A supplier is here because growers buy from them and speak well of them. That is the entire admission standard, and it is also why you can trust the shelf.
Agriculture suppliers rename and merge constantly: Autogrow became WayBeyond, Nexus and Rough Brothers became Prospiant, Kitazawa became True Leaf, Jain's irrigation lines moved under Rivulis. When a company on this shelf has renamed, the card carries the current name and we retire the old one, so you land on the real company instead of a parked domain.
