Hey everyone, this is my first post on grass city! I just started a hydro grow my friends and I have been working on for the past month. This isn't my first grow but tips are always helpful. I'm going with a SWC and these sweet sprayers my buddy found online. I just put the clones into the first machine that uses 15 florescent lights for about a week just to get the roots going. I didn't want to kill the clones with the 600w hps/mh mix just yet, Just until the roots drop. I have skywalker, pre 98 bubba kush, and OG cooking atm, more to come. Let me know what you think!
