Silica adds substance and UV-B will get you more THC; more stoned. UV-B is available from the pet shop as lizard lamps. Recomend output rating of 10.0 < a good one is ZooMed ReptiSun 10.0. Or suntanning lamps are made with UV also. I have a small Sperti Suntan Lamp 800 watts 30%UV-B. The lizard bulbs need annual changing.
