I understand the science behind the need for silica but I broke a branch off a plant in DWC and thought that silica would make a difference and I didn’t notice a difference at all, plants still remained fragile. I’m a huge fan of the GH lineup but I think armor si is pointless

Hands down needed for stress and heat management. It just makes your plants stronger indoors and outdoors.The first thing added to your tap water to feed your medicinal garden. Can be used with any food ....

Started using halfway through veg, havent noticed any change in stem growth speed yet. Mainstem is large but it was growing pretty fast already. Will change review if it works better next time.

Product is good, been using the GH line for a while however the bottle was opened and leaked all over the box, otherwise would have given 4 stars.

Great value, this product lasts a long time! Make sure you add it to your water first then mix other nutrients. It really helps balance out the pH.

So many advantages using silica of any brand... But Armor Si has a very strong concentration versus other brands, and remains among the cheapest.

Noticed an improvement after using on my garden as a foliar spray and nutrient additive. Will definitely buy more soon

Plants love it. I won't grow without it. Leaves and stalks are much healthier with silica.

Works great like always, strengthens stems and stalks and overall plant structure.
