Review: 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.
Review: One of the must have for growing Cannabis. I have done side by side comparison with this and without and the plants without are so bridle and easy to break when super cropping and the root balls are quite smaller. The plants with it heck I can't bend twist roll whatever and they will not break the root balls and so huge and white like a freshly broke Bone. Only down side of this product is it will raise your Ph good lord will it raise it so be prepared to use more ph down but it is worth it you will not be discouraged

**Q: which product in the GH flora series do you add first . both armor si and flora micro claim they need to be added  first**
A: Always add your silicate first allowing it to dissipate completely in the water prior to adding anything else. 5mins or so...The silica will bind to everything around it locking everything out so don’t give it anything to bind to..

**Q: Can silica be used in early flower at heavier doses to reduce plant stretch and node spacing?**
A: Hello,

Silica can be used in early flower.  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.  

Thanks,

Eco

**Q: Does it kill microbes?**
A: No

### ⭐⭐⭐⭐⭐ Review
*by B***K on 18 July 2019*

First-time user, and I believe I am seeing some substantial results in terms of plant structure and sturdiness. Full disclosure - this is my second personal cannabis grow, and improved knowledge and training practices since my first grow may also have contributed to my success, so take this with a grain of salt. I have been applying 1ml per litre and adding the completed mix to both my DWC (Deep Water Culture) hydroponic systems as well as my Fabric Pot outdoor plants. Plant stems and stalks are approximately triple the strength/thickness of my previous grow, and there is a sort of durability to the leaves that was not present in my earlier grows, feeling thicker and possibly larger (hard to attribute directly to silica since I am training these plants - LST - Low Stress Training - differently than my last grow, but seems likely). There is almost a slight 'waxiness'to some of the larger, more developed leaves. They seem to be able to handle heat stress very well, where my first grow had issues now and then under standard LED lighting, these plants can take the pressure of newer 2000w lights with COBs and additional supplemental lighting without issue. In short, there is probably triple the intensity of light in my tent now than last time and there is virtually no sign of heat-stress. On the negative side, over-feeding silica seems to have a detrimental side-effect: branches may snap easier under pressure if too much is applied. I doubled the silica feed on one my plants to test the results of silica feeding. This is the only plant i overfed, and when employing LST (Low Stress Training - bending and shaping the plant into a desired shape - in my case a flat bush) the plant became harder to bend, and inevitably easier to break. This plant was for all intents and purposes the same as the others in terms of size and shape, except of a slightly different strain. Again, take that with a grain of salt. The branches could not bend easily and I ended up breaking a large branch at the base. I repaired that and moved on to the next, but not before easily snapping off another fan leaf, also at the base. I tried again to work on another branch but felt resistance and now knew what came next. I believe that the over-feeding of silica is causing the branches to become too rigid and too heavy to properly support themselves. Lesson learned. Summary - Too much of a good thing is not a good thing. But just the right amount is great. Note: Don't use this product when entering the flowering cycle. Waxy cannabis flowers aren't very useful.
