I think horsetail and comfrey both are great for silica, but I don't know from experience - just from reading here and icmag.
I'm no expert, I don't claim to be. I'm probably the dumbest dude here when it comes to all this growing stuff. I'm new, very new to it but I read alot and I try to learn as much as I can. Every single day I'm on here and other forums reading, several hours. I read so much that I can't even remember half the shit most of the time, I have to take notes.
Rrog has helped me more than anyone, on any forum. He will spoon feed me all I need, even the most basic, most obvious shit. This guy is truly exceptional and I'm very glad to have him here. I'm not "ass grabing" I'm just showing my appreciation.
I'm sorry if I offended anyone, when I seen someone say that "everyone should use protekt" I thought.. well shit I needa get me some of that! Then I seen the bottle, and while it may just be a label, it screams "market hype" to me. It doesn't say anything about being organic which led me to believe there are some sorta chemicals that I don't want. If the product doesn't say organic, or is listed organic - I question it and most likely won't touch it. If they're making silica into a plant useable form, there's gotta be some kinda chemicals they're using to do that. I'm the kinda guy that likes to take the less beaten path in life, I hate to follow crowds, I hate to follow trends and I question everything. I like to understand the why's and hows.
If some of you choose to use protekt, that's awesome. I don't judge you, or look down on you. I don't have a pissing contest about it. I was just simply stating my doubt publicly, maybe I should have kept it to myself.
So once again, I'm sorry to those I offended, I surely did not mean to.
With that said... that c99 looks amzing myco... I'm growing c99 right now about 1 month into veg. Hoping my flowers can look as good as those do!
