you'll get mixed reviews on fem seeds. i love them, have never even once had a hermie. check out
www.drchronic.com and
www.cannabean.com both of these sites have great prices and super stealth shipping. to render pollen inert, spray it with water. plain tap water. if you need to de-pollenize your box just mist the whole thing inside and out till it's dripping. then just wipe it down really good. maybe mix a teaspoon of bleach into the spraybottle to sanitize your cab while your at it. good luck bro!
