This is pretty awesome. A lot of vegetables are grown in greenhouses, but traditional greenhouses are quite energy intensive. Anything that reduces the need for greenhouse area could save quite a bit of carbon. Paired with techniques [1] to reduce the amount of heating needed, this could be a real game changer.

A long time ago I was looking at artificial chlorophyll. About all I remember is that in comparison to inorganics, that stuff's already super wideband and detuned.

(OP is definitely a cool approach, anyone know anything about last year's progress in artificial chlorophylls?)

Edit: as to the effects of speeding up plant growth, we've already had several instances in history where more intensive agricultual techniques have improved crop yields, some of which were by increasing number of harvests/season.

1200sq ft is currently $3600. https://www.ubiqd.shop/collections/frontpage/products/ubigro... Also, whitepaper/case studies: https://img1.wsimg.com/blobby/go/e91a4987-3726-410f-8e4a-95c...

White paper tldr: between +5% (cannabis) and +20% yield (tomatoes).

This is huge.
