Synned: thanks for the info but its not straight FFOF. i cut it 50/50 with FFLW so shouldnt have an issue there. thats what i thought it was at 1st but then i used organic soil and same thing happened. im 99% sure its a off-gas issue from the tent. ive moved all new ones out of the tent and time will tell. also contacted hydrohut to request a new tent!!
