We could sit here day after day and never come to any one conclusion. You believe totally that it helped and I don't. You continue to use them and I won't. But it is curious if you believe they helped so much why was it that the person that caused you to use the 'magic rocks' didn't use them in their last/current grows? You sure think that if it was such a boom to growing that they would've had them incorporated into those grows. Kinda makes you wonder. Or at least it does to someone with an open mind.

As far as the mold? Well as I understand it you don't just throw a couple light colored rocks in there. You cover the top of the soil with a layer of them for..."maximum light reflectancy". If this is so anytime you cover the soil, add water and then heat, you promote mold.

I'm done with this. Sorry SK for this taking up so much of your threads space.
