I'm still have a few things to get before I am totally ready.. Mainly a tds meter.. But had a few questions. My set up is a 600w for budding. I have fox farm fert. Running a 18 gal res with air stone. I'll attach a pic to show the set up. It's home made so don't laugh to much.. Lol. I'm gonna use another tote to veg with some floros. I'll have a air stone in that as well. I would like to know how often should I run the water timer in my rail set up? I was thinking like 15 on 45 off. Also what should my ppm be. From what I read I need them around 250 during clone and start veg. Then up to say 500-600ppm in veg and 1500 during flower.. Is that sounding about right Been in soil for a couple years. Want to switch over with few issues as possible..
