BAC Silica power.. Is it good?

Is this a good silica product?
I search a lot and can't find any review about it and never read someone saying they use it or recommend it... which could mean a lot..
so, because i intend to try a silica product for the first time and in my growshop this is the only silica product they have, i thought i should ask some opinions from you people who are more experienced
the product itself is quite expensive, too, and i wouldn't just buy it before asking, you know...
so, any opinion on this will be much appreciated
thank you very much!!!

peace!

Yes, great product. On my second bottle now. It lasts a long time as the application is only 0.1-0.3ml per litre.

Definitely feel my plants are sturdier and hardier, more tree like to hold weight with ease. I don't even check for pests or anything anymore.

I grow under leds, using the full bio canna line at full strength + + great white mycorrhizae (feed-feed-plain 0.4ec water). Silica with every feed (add silica first into the water (0.4ec) and let it mix for 10 min before adding the rest of nutrients).

I stop applying silica at week 7 (10 week plants) and week 9 (12 week plants like Ghost Train Haze) of flowering respectively.

I grow on 5Lt pots and the ghost train haze produces regularly 125-130grams but more is not out of the question. 5 of those alongside the stand up fan, produce 600+ grams easily on 1mt2.

Don't know how important is the silica in all of this, but consider I'm far from an expert but a stoner. I like to make things as easier as possible (measuring PH for example, no thanks...), so if it is the silica that let me get away with not putting on much effort on growing, the price its well worth it.
