Do a side by side. Plant one in a smaller container and do your normal transplanting. Plant the other, in a much larger pot say 10 -20gal. Water accordingly. The results may surprise you. From my experience, the ruderalis hybrids do best with a vast space for root development and nutrient uptake. The best organic practices in my opinion will allow you to use water only. In that you wouldn't be transplanting the one, layering accordingly is a must. The seedling will of course require less, and should be accounted for when building the layered medium. GL
