Our SS offerings were created through a proprietary staminate flower/ pollen production method that targets multiple plant hormone pathways. It is not related to plant stress but a direct intervention of the natural hormonal state. This method is incredibly effective at producing pollen, much much more so than colloidal silver, and significantly more effective than Silver Thiosulfate in terms of overall pollen production .

can't find where i read about it but maybe someone else can, its here somewhere... unless i dream't it up lol.
To the large and singular furniture of this noble island i have added from foreign places all the variety of herbs and flowers that i might any way obtain.
i've laboured with the soil to make it fit for plants, and with the plants that they might delight in the soil - so they might live and prosper under our climate as in their native and proper country.
