I've only been growing a little over a year but this stuff blows me away. I'm running autos in Earthboxes and that combine with MontanaGrow's Silica has made my stalks extremely thick by only 38 days old. I'm not sure how my gals are going to finish but I might have to bust out the real saw come harvest.

I finally found a great source for silica. I’ve had my ups and downs with Silica Blast as I bet others have. Like everything else BAS offers, this stuff is top notch and won’t screw with your plant’s ph like the bottled products can

The summers, in northwest Oregon, have changed, with more days in the 90's and 100's. Silica is an excellant amendment to help regulate soil biology. Great texture with Montana Silicate.

As suggested on MontanaGrow's website, I planted 2 containers of the same flowers, 1 with Silica, 1 without. The one with silica not only had more lush growth, but after being away for 8 days on vacation at the end of July, the MontanaGrow plant was still alive without watering, while the other planting was all dried up. I also used it and BioTone to revive used potting soil, and the lettuce in it compared to new potting soil grew twice as big. The lettuce in the picture were started at the same time.

You never know how much you need something until you try it out. I used to SCROG like a madman. Now, I only use one at the end of the run for support on the biggest buds. The plants come out so stout it's unnecessary now. Just like CoWoCo, the cheap alternatives end up being more expensive because they're way less effective. So you have to use more. I've always used a silica amendment, but now I'm sticking with Montana Grow.

I've tried every silica under the sun....from cheap liquid, to monosilicic acid silica including Power Si Original and Bloom, dry powder, but Montana Grow is hands down the absolute best because it's NOT ONLY silica but it comes with a lot of minerals, trace elements, calcium, and some other molecular stuff and the way Jeremy grind it up is perfect because it comes as powder as well as bigger chunks and the bigger chunks with work as slow release while powder would be available after a couple of days after the microbes convert it to monosilicic acid. FYI... if you want to reuse your soil for 2nd or 3rd, etc run then I recommend grinding it up to complete powder so you can topdress it once in early VEG and once more after stretch in bloom so after 21 days in flower I'd topdress them again to help support all that weight from heavy nugs and help with other things that Silica is known for. Happy growing 🪴🗣️💨
