hi all ive been lurking on this site for about a year. and i had a couple of questions. 1. on the indoor/outdoor thermometer im using a 400w hps and the outdoor goes to 97 while the indoor is at 78. when i was using cfl's they stayed close to the same temps 77-82. im just wondering if its too hot or im tripping. 2. re using dirt? i was thinking about starting a compost heap and throwing the used dirt (FFOF) and mixing it with regular dirt. this is my first grow to make it to flowering last one died from using mg organic with no extra nutes.
