See IF you can get DR. Earth or similiar; Organic Soil with Mycor...(those natural soil=probiotics!) A well thought out Soil like this won't be available everywhere, but search and you'll find-it! This is my 1st Indoor (going into 13th week) and the Soil mentioned has been very successful, and i have not attracted any bad bugs, just mini-mini-fly's and they seem to benefit the plant! Thought about bringing in a Praying Mantis i found, but don't seem to need him. Oh, using "OneNess" by Humboldt Nutrients as Feed/H2O-2-3 times daily; 3 small scoops;maybe 3 ounces each, AND The Exhale; CO2 Bag=effective and Cheap; Running One 400W using MH and just introduced the SPS bulb, using Electronic Energy Saving Ballast with 4X4X76" Grow Tent.
