Well I am starting tomorrow and I am super excited to go pick up my clones. Anyways my set up so far is an attic grow. I covered the walls with mylar and plastic sheeting since there is fiber glass. Then I laid down a 6x3 board. I am going to 18 plants in 2 gallon buckets that'll cover 2.5x5.5 under a 1000 watt HPS Lumatek light. Hullwhatever bulb and I have one fan. But I got a couple questions. 1) Will that light cover enough space? If not I plan on buying two three foot floro tubes and hanging them down on the sides so the outside plants get enough light. 2) I am using Fox Farms Organic soil, it has some fish on it. Guy at the hydroponics store suggested it, so should I add perlite or nah? 3) What yield will I be expecting? I would like a pound off 18 plants I plan on upgrading later on by selling my one light and buying two 600 watt so I can cover more space. Also is it worth investing in c02? I might do it on my next grow. Thanks a bunch, sorry I have so many questions I am just so excited.
