About Growlightia

GrowLightia was founded by an electronics engineer and an impatient gardener — the same person, actually, and the tension shows. After one too many fixtures whose specs dissolved under a quantum meter, we started publishing the grid maps ourselves, then designing boards that made the maps look good without asterisks.

Every fixture we sell is measured on our own bench: efficacy, corner PPFD, spectrum, and noise (which should be none). The maps are on every listing. If a number is missing, we haven't finished measuring — we don't round up and we don't say 'equivalent.'
