Just starting off my second grow, had all 4 seeds sprout in Peat Pellets. 2 Gorilla Glue, 2 Blue Dream. I modified some 5 gal storage containers from home depot to use as pots. Filled them up with Organic potting soil and put the peat pellets right in the soil. I'm using 4 1000w equivalent Sunraise LED grow lights and the room has a 4 inch fan vented to the outside.
