Nocturnal Lantern is bugged. Search forum for "nocturnal", you will see the details, but you can't get it in green from planting. Thunderhoof Grass you can.
However, they messed up the seed distribution. The stretched 60-80 to give the same mats and then they stacked all high level mats on 79 seed. So, you will be getting some L75 mats in green, but not a huge lot.
If you are serious about production in quantity, you will need to supplement your planting with buying the mats. L70 food mats are from TOSH-entrance Black Codex vendors, L75 are from Chrysalia. 30 mentos is not unreasonable for a stack of green mats.

Oh, and people who have more than 3 classes are clinically insane.
