I always wondered about this since one of the guys at my local hydro shop who's actually pretty knowledgeable suggested I add this as well, but I kinda assumed it was snake oil without really looking it up. There seems to be a wide variety of products for silica supplements, I wouldn't mind something like ArmorSi or Silica Blast since these are only $30 a gallon at my store, but some of the other ones (name failing me right now) run like $70 for a pint. Which one do you use and at what rate?

I use Agsil 16H. I've only used it with soil but here is a website that'll give you the application rates.

I used Dyna-gro Protekt before I switched to soil.. Good product at a decent price..

Cheers, thanks for the info on the silica, I'll look into adding that into my next grow. Is everyone adding this to the res or are you foliar spraying it?
