Momentarily puzzled by the mention of plant food, as none of these crops are carnivorous, Thor's eye lights up a little as he realizes there's something he can do here. Something helpful. Something that Loki had urged him to do, in vague muddled memories, which he had nearly forgotten. "No need. Just a moment."

Thor reaches out a hand over the waiting earth, and closes his eye. Faint wisps of blue seidr curl around his palm, like a gentler rendition of the lightning he has called on for centuries, and while it has been quite some time since Thor has blessed a field, he has not forgotten how. His magic sinks into the dirt, darkening its dusty hue to a richer brown, infusing it with nitrogen and phosphorus, strengthening the soil's ability to support life. The air inside the greenhouse slowly becomes a little more humid, and while the cloudy skies still hide the sun, the daylight is still enough to warm the enclosed space to a comfortable temperature.

He opens his eye again, looking over his handiwork with a small, hopeful smile. "That's better."
