Cotton discs with a blend of sodium alginate and germination compounds were blended into a hydrogel and planted with green onion seeds in order to determine a resulting increase of germination rate. After its product viability was determined, apparatus design was reevaluated to minimize seed suffocation effects with varied results dependent on disc thickness. Though the germination rates were lower than planting regularly, it is believed that if the gel’s physical construction could more resemble soil, the suffocation factor would be negligible and drought tolerance can be more accurately measured.
