10k. I'm sorry, but your wrong friend. I hate soil and I am forced to have my gifted moms in them. They are growing just as fast, if not faster under very low light and hydro ferts in FFOF. I grow NFT in small RW cubes primarily, and the vegging is pretty much identical. 1" a day??? that's really nothing to brag about. my SFV grows 2+'' daily. I had a SSH grow over 6" in 24 hours. you gotta be able to distinguish when to feed, when to flush, and how much ferts @ givin PH in ANY medium. I can't say running organics is going to slow the process because I never compared. I can tell you that my current moms were vegged in "organic" FFOF soil and didn't get ferts amended for about 5 weeks. they got some hydro food and the growth rates havent changed. they get food 1 week. water the next. growth just began accelerating after taking cuts. Is it the hydro ferts, or the soil? or the the rootmass I now have 2 months later???
