This is a full on experiment, first to test my grow skills, second, to mimic coco as closely as possible with inert soil and smart bags. I know I could have made this all very simple, yet, I have been growing for four years and although I have done well for myself with nice yields, I want to test myself, explore this concept fully. I hope everyone enjoys this little snippet of my experiment, that picture is of my plants growing in inert soil in 4 weeks and three days of bloom. My lights Meizhi 1200 watt(568 watts actual) in a 4x4x7 tent generic, intake outtake fans, my humidity stays in the range of 40-55%, temperature stays between 68(at night) and 80(at daytime). I use tap water, I do not measure EC or PPM, just never needed to and will not do it. I am using dynagro nutes, foilage and bloom, and I have added calmag from general hydroponics, I vegged for about three weeks under a weaker lamp, and then moved to tent.
