GH Armor Si Quart (12/Cs)

This stuff does wonders for your plants. I'm sure you could go a whole grow cycle without it however it makes such a big difference in the overall strength in the stem since it helps produce this giant kuncles on the stem of the nodes. I'm not done with my grow yet but I have no doubt that the plant will be able to support all of its flowers. Furthermore, you can use this stuff pretty sparingly so it's gonna last you FOREVER. Overall, I think it's worth the investment.

Works wonders

A lot of silica additives are the same as their purpose is to help increase the strength of the stalk’s cell walls. I’ve tried several brands and keep going back to this one. Something tells me it just blends with my recipe better than many other brands, possibly the additional potassium but it seems to be more compatible than Advanced Nutrients Rhino Skin (which I really, really like and still use when I can’t get this) and Botanicare Silica Blast (just below Rhino Skin imo and is my third string silica). After many runs of each brand and a couple not named, I’ve pretty much settled on Armor Si.

I’ve been using the General Hydroponics Armor Si for a few weeks now, and I am genuinely impressed with the results! This water-based nutrient solution is easy to mix and apply, and I’ve already noticed a noticeable improvement in my plants' health and growth.

This is a must have
