Narrator Grant “The King of Random” Thompson goes through a step-by-step breakdown of how you can take some mundane diapers and convert them into water-storing gel that your plants will love, poses no harm to the environment and keeps your plants consistently hydrated; freeing up time that you might otherwise spend watering plants.
Thompson’s recipe for super absorbent hydro-soil requires that your diapers be of the disposable kind and that they have experienced little to no intended use; the reason that Thompson recommends diapers is for their inner layer of sponge-like crystals. He further demonstrates this property by pouring four cups of liquid directly onto an opened diaper and that not a single droplet can escape after relatively little time. Thompson then rips the exterior of the diaper and dumps the saturated absorbing crystals into a large bowl, adds some more water to the mixture and massages it with his hands to make sure everything is fully saturated.
Beyond its uses as a gardening aid, which should be mixed in equal parts with potting soil; Thompson points out that this hydro-gel can make for an excellent improved cooling pad by sealing it within a zip-lock bag and leaving it to freeze. He also comments that in addition to halving the frequency of necessary watering sessions for your plants, that the very nature of the hydro-soil’s absorbing crystals can serve as an insurance policy against over-watering; excess water simply stays within the crystals until such time that the plant draws water.
