Hey you guys, I'm also planning on starting a small grow just for personal use. I ordered 3 Northern light seeds from herbies(autoflower), and I've got a 4x2x5 tent, moisture control soil, the nessesary pots, and a muffin fan(already connected to an 12v for the wall). Heres the light setup I ordered. <a data-ipb='nomediaparse' href=''>http://www.amazon.co...=A2WRS4X4C0GMOQ</a> Theres just a few things that I'm curious about. -Is there like an "all purpose" nutrient solution I could purchase? -Will that one muffin fan be enough to circulate new air through the tent? -If I've got this setup in the attic above my garage and make one of those make-shift "smell absorbing" tools, would it be overwhelming? I only plan on growing two at a time. -Is the wattage on the lights(400W) enough for 2 plants all the way through the cycle? -Also, I'm not too educated on PH I've read a few articles on it but I'm not sure about how much acid or base to apply. Also what the ideal PH is. Thank you to anyone that provides info and I look forward to starting a journal!
