Review: It just works, promotes strong branch development, seemingly helps with high heat environments too - I've grown with and without this product to compare. This does seem to promote strong thicker trunk/branch development, along with faster recovering time after pruning. Seems to give plants a higher tolerance to heat as well. Just using the recommended dosage on the bottle and slowly ramping up as the plant grows. A little goes a long way. I would say this is a good value for the money. Review: Amazing product - Awesome stuff, reduced the risk of powdery mildew on my cannabis plants and increased the resistance to insect damage and temperature related stress. Much more stable than ProTekt, which crystallized bad around the lid. Plenty of potassium to act as a bloom booster as well. Highly recommended. I used at half strength during early veg and boosted to full strength during growth spurts and into flowering. ## Features - Causes skin irritation. - Armor Si is suitable for all types of plants during all stages of growth - Use as a growth enhancer with irrigation water or in addition to your regular fertilizers - Armor Si improves plant structure and foliar development, increases yield and improves flower and fruit production ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E5K5NS0 | | Best Sellers Rank | 587,592 in Garden ( See Top 100 in Garden ) 775 in Hydroponic Growing Kits & Systems | | Brand | General Hydroponics | | Brand Name | General Hydroponics | | Coverage | Medium | | Customer Reviews | 4.7 out of 5 stars 1,626 Reviews | | Global Trade Identification Number | 00793094017824 | | Item Form | Liquid | | Item Weight | 2.4 Pounds | | Item form | Liquid | | Item weight | 2.4 Pounds | | Liquid Volume | 32 Fluid Ounces | | Liquid volume | 32 Fluid Ounces | | Manufacturer | Hydrofarm, Inc. | | Mixing Ratio | 1:20 (1 part Armor Si to 20 parts water) | | Model Number | GH1782 | | Number of Items | 1 | | Part Number | HGC732802 | | Specific Uses For Product | Hydroponics | | Specific uses for product | Hydroponics | | Target Species | plants | | UPC | 793094000000 793094017824 827165706284 | | Unit Count | 946.3529 millilitre | ## Product Details - **Brand:** General Hydroponics - **Item form:** Liquid - **Item weight:** 2.4 Pounds - **Liquid volume:** 32 Fluid Ounces - **Specific uses for product:** Hydroponics ## Images ![Armor SI for Gardening, 32-Ounce - Image 1](https://m.media-amazon.com/images/I/51wIr0+y4fL.jpg) ![Armor SI for Gardening, 32-Ounce - Image 2](https://m.media-amazon.com/images/I/5110HpCQkyS.jpg) ## Questions & Answers **Q: Can we use as foliar?** A: Armor Si™ is suitable for all types of plants during all stages of growth.

It helps with stem and stock thickness as well as heat and drought resistance. Keep in mind silica supplements are alkaline and will raise your ph.
