AAAAllll right guys....im all skeptic about it but i will give it a try on my next clone run and see! I appreciated your hints!

Well......damn, it DID work indeed!
I got a small bottle and as soon as i did the first application my plants started showing overfeeding, mainly of P.....so I backed the feedings from feeding everytime to once every two plain waterings...
Yes the buds are way more frosty, the tricomes are waaaay bigger as i can see with my eyes....
I noticed that the products has Alfalfa extract in it , i didnt like the idea to use it during flowering cause of the N boost, i wasnt happy about it, but now im pretty convinced that maybe even the extract contributed to the frostiness....donno....but for the price of the bottle and the results ill keep usin it

Has anyone used their Silica? Or is there a less expensive alternative that works just as well?

I use AgSil 16H from Custom hydro nutrients and mix It with RO water.
add 148g to 1 liter of ro or distilled water and use 1ml per gallon.
always add silica first and give plenty of time to mix. I run a submersible pump in the res for at least 15min.
