i mean you could waste you cash buying gel or even further with solutions but you in no way need any of them not to long ago i built two dwc cloners out of plastic coffee cans one i used clone gel the other strait tap water just to run a control all clones were of the same strain some strains will root faster then others in my finding the gel cloner n the strait tap water cloner rooted at the same time.maybe using hormones gives people a sense of security.ive read people post saying alls they use is a cutting a cup n a little water thats it no hormones oxeganated water notin and claim great results.i dont see no reason why you couldnt reuse your plugs maybe give them a quick wash with hot water and soap.do you think you could reuse the cloner after its first use?just kidding bro keep on growing,keep it green most of all respect my boy charlie sheen i dont know where that came from just having fun im at work right now n im just tryin to pas the time
