Recommendations on Silica

I grow indoor in coco and use canna A+B. I see lots of people use a silica additive. What’s the best to use? What part of the grow cycle to add it or frequency and does it raise EC? Thanks in advance for any help.

Hey thanks man appreciate the info. I have been studying up on it. Dam there are lots of options out there even a silica acid which is insanely expensive.

Bloom City makes a fantastic silica. I switched to this brand over 2 years ago. I no longer have to stake down or tie down my monsters because the silica toughens the colas so good. Plant below has over 10 colas and yielded 1 lb 5 oz and didn’t have a single stake it stood up by itself and didn’t even bend

I use silica blast. Rice hulls also add silica if want organic.
