I know this is an old thread but I have a pretty simple question that sort of pertains to this topic. Im new to hydro, DWC Bubbleponics specifically. I have a 4'x4'x6.5' Mylar Grow Tent, 1000w MH&HPS Switchable Light System, 440cfm Exhaust w/8"x20" Austrailian Carbon Filter, and 3 5gal bubble buckets. Since im new to this im thinking of starting with GH Flora Series Performance Pack. Is this enough to get through a 2.5-3 month grow with 3 plants and are these nutrients the lowest quailty, most basic regime for hydro grows like most of the pro's suggest? I know theres Canna, Fox Farms, and many others that are suggested to be advanced nutrient systems but isnt GH Flora specifically formulated for high performance hydro culture also? I know there are flavor enhancers and all that stuff but those are mostly sugar based and plants do not absorb sugars. They produce sugars and leech sugars into the subtrate to take care of thier symbiotic microbes such as mycorrhyzae. There are many growers that dont know these things. Anyway, quality of GH Flora Series, and grows per starter pack? If the starter pack doesnt get through at least one entire grow its surely not worth $40!
