I can say with certainty that the AG nutes seem to work just fine. I'm sure some of those other brands out there may work better especially during flowering perhaps. But remember all 7 sockets/ pod holes are filled with herbs. I've got parsley, thyme, oregano and sage in the other 6 pods. Like I said in a previous post, however, those have taken a backseat to the ganj and are small, having grown very little since the bud has gotten bigger. I just let 'em go and focused on the plant in question. I opened my closet this morning to see like double the flowers (white pistils anyway) from yesterday. It is really taking off. Soon I'm going to have to remove the hood from the arm, drop the base to the floor and hang the hood from a rack to accommodate the size of this thing. From what I understand the plant can practically double in size with the colas growing up and up.
