IMHO your going to have more trouble with autos growing then photos..just from being new to this...autos have a predetermined finishing time so 1 little mess up, it will significantly hurt your yield...1 little mess up with a photo , you just veg another week and it's corrected....I just wouldn't grow autos until you have your room dialed in and your soil, and fertilizer...but first and foremost WHATEVER you do, make sure you add perlite into your soil....you will thank me fornthat, your drainage will be 10x better
