Hello fellow tokers! I am halfway into my noobie setup and I'd like some advice before I make any major mistakes. I have spent hours & hours doing book and online research and depriving myself of simple pleasures to save cash to get started, so I'm super excited and anxious to get it right. I'm hoping you guys will humor my craziness and offer whatever sage advice of which you feel I am worthy. Ok, so far I have: A reflective grow tent (76x76x76in) One 600-watt dimmable ballast (50-75-100%) A cheap reflective hood 1 each 600w MH & HPS bulb (to be alternated or used with an additional setup) and a digital hygrometer. I suck with soil so I'd like to try a DWC setup with 5-gal buckets, fitting net pot lids, and hydroton medium. I'll be sure to aerate. I was thinking one of those bubble disks. What do you guys think? I found a digital pH tester on amazon for $22.95, its "Milwaukee Instruments PH600AQ Ph Tester With 1 Point Manual Calibration". I'm not 100% sure if it's worth spending the cash to start with, or if that can wait. Any thoughts? I'm concerned with ventilation, maybe too much so. Those inline fans are expensive! The room my tent is in gets pretty cold at night so I was hoping I could get by with that and an oscillating fan for a short period. I will eventually try the DIY carbon scrubber I found on here, when smell becomes an issue. I am a prop 215 patient in Cali, but I don't want to upset the neighbors An advice you wise ones wish to bestow upon me will be greatly appreciated!
