Never even occurred to me..ick Bet that would certainly have something to do with it. I personally have only had that with MG soil but like you said they would have eggs in it if stored in the elements. I think people can practice/excel on just about any type they want its not hard to adjust based on results and experience. Use whats available to you and what works for ya. Anything tailored to Cannabis is worth a look but keeping things basic and simple is all that is needed.
