lol i know this is a total gravedig but i have to say the idea of having tons of spiders in my grow space sounds absolutely aweful.i recently brought some spiders into my outdoor growing space and it seems to be working great..and all kinds of different stuff to buy at local pet shop that will kill bugs around your plants and doesnt harm your plant...(praying mansis,ladybugs,spiders) ...im sure all that spray shit works but i still hate using it..
