'...the Medicine Garden is already complete.' Ashton mused inwardly.
'A temporal array had been installed around the garden to hasten the growth of the herbs. It is rather unfortunate that they have to be raised in a greenhouse but the density of Spiritual Energy in there should be enough to compensate for that.'
Raising Medicinal Herbs in a greenhouse makes them weaker compared to those that grew out in the wild naturally. They'll need more care if they were to be handled as well.
While Ashton could simulate harsh weather to neutralize this, doing that would be a bit wasteful. It's almost guaranteed that the ones who weren't able to hold on will be thrown away in the trash. Ashton didn't like the sound of that so they might as well just stick to the path that will give them the most optimal results.
