The Greenhouse Seeds GWS is nothing compared to MNS Shark Shock. The MNS Shark Shock is one of my all time favs. The Greenhouse was feminized seeds that all hermied. No light leaks or anything to trigger them to hermy. There were otherplants ffrom other strains that were just fine. The Greenhouse version is short and squat showing more Indica as opposed to MNS which is taller, yeilds more and is much tastier. No contest on this one.
