Yeah I always use Shroud Topsoil on Krakka Roots and I get piles of Sylkis Bud seeds (in average more that if I'd use Thanalan Topsoil) and as added bonus double amount of Krakka Roots as well. It's well worth it if you run multipply gardens / repeated loops. Get over 150 Sylkis just in couple of weeks, planning to move to next stage (Sylkis & Boombrush) nex week, still need a few more Broombrush seeds to be able to fill most of the garden Garden patches in one go ...
