First, I do not understand why the silica? Drainage? If drainage why not more perlite?

I would like to know how to enlarge and strengthen stems with a short veg time. I keep a fan on them, but they just get so big, and not big enough to support the main top.....Ya I know, bummer of a problem:jointsmile:
WashougalWonder Reviewed by WashougalWonder on . Searching for a method to add silica to my grow.....Right now I have at least a few plants after transplanting from clone to 1 gal then to 3 gal that die....everyone of them die from some type of stem problem....seems like the area is right where the stem enters the soil there is a problem...starts to dry out and boom dies....I was thinking that maybe if silica was added....it would get that stalk nice and thick and strong, most of those problems would go away... Just a thought.... Anyone have any thoughts? Rating: 5
